Suitable parts for John Deere riding lawn mowers should match the mower model, deck configuration, and replacement-part number before price or convenience becomes a deciding factor. The supplied data compares 10 products, including ignition keys, deck gauge wheels, a starter solenoid, and a spindle assembly. The strongest evidence is product-level fitment information and listed dimensions or replacement numbers. That evidence can help narrow a purchase, but it cannot confirm installation success on every tractor variant, long-term durability, measured performance, or the accuracy of every manufacturer compatibility claim.
Buyers should treat this roundup as a screening guide rather than a substitute for checking the mower identification label and parts diagram. The Fourtry GY20454 Spindle and AM125172 gauge-wheel kit provide more concrete fitment detail than products with missing specifications, while the GY20680 GX24332 keys are a simpler model-matching purchase. Readers comparing replacement components may also find useful context in Lawn Mowers & Tractors and our guide to top-rated residential riding lawn mowers.
Evidence-Based Shortlist
- Best supported for deck-height maintenance: 4 Pack AM125172 Plastic Deck Gauge Wheel Kit Compatible with John Deere 48″, 54″, 60″, 62“, 72” Deck Lawn Tractor Mowers Wheel Kit, AM124706, 210-300, based on its listed series coverage, deck sizes, wheel dimensions, bushings, grease zerks, and included bolts. The limitation is that the supplied data does not verify fit on a specific mower serial-number variant.
- Best supported for a listed spindle replacement: Fourtry GY20454 Spindle Fit for John Dee re Mower – Spindle Assembly Fit for John Dee re LA135 LA115 LA125 LA145 LA105 LA130 D140 D130 D105 D110 L110 X110 42″ 48″ Lawn Mower Tractor, Replace GY20962, based on the exact replacement number and named mower and deck applications. Specifications beyond the title-level fitment are not supplied.
- Best supported for replacing lost ignition keys: Gy20680 Gx24332 Lgnition Keys Replacement for John Deere D100 D105 D110 D120 D130 D140 D150 D155 D160 D170 Lawn Tractors (3 Pack), based on the GY20680 and GX24332 part numbers and its named D-series coverage. Buyers still need to confirm the machine model before ordering.
- Best supported for a broad starter-circuit replacement: Tecreddy Starter Solenoid for John Deere AM138068 Cub Cadet 725-04439 MTD Troy-Bilt Trombetta 862-1211-211-16 Riding Lawn Mower Tractor, based on its 12V description, replacement numbers, and extensive listed model coverage. The supplied data does not establish electrical testing or compatibility with every listed application.
Pros
- Generous listed dimensions can cover many riding mower shapes and decks
- Coated Oxford fabric helps guard stored equipment against rain, snow, dust, and dirt
- Elasticized lower edge provides a more secure fit than a loose draped cover
- Storage bag helps keep the cover contained between uses
- A 60-day exchange or refund policy and one-year limited warranty are supplied
Cons
- The listed 72 by 54 by 46-inch size may not fit larger or unusually shaped mowers
- Outdoor exposure can make fit and wind retention especially important for buyers in severe weather
- The product data does not specify ventilation, fasteners beyond the elastic hem, or cleaning instructions
Riding Lawn Mower Cover is best for owners who need basic outdoor protection for a compatible riding mower or lawn tractor, because its listed 72 by 54 by 46-inch dimensions cover the machine and its coated fabric is intended to resist weather. Fit is the deciding factor, however, so buyers should compare those measurements with the mower before ordering.
The cover focuses on reducing exposure to rain, snow, wind, dust, and dirt because the supplied description identifies those storage conditions. Its 420D Oxford polyester fabric and polyurethane coating provide the stated material and water-resistance basis, while seamless stitching is intended to limit water entry. These features can reduce direct exposure during storage, though the product data does not establish how it performs under prolonged or severe weather.
An elastic hem around the bottom helps hold the cover against the mower because the description says it is designed to reduce the chance of being blown away. That is useful for open storage areas where wind is a concern, though no straps, buckles, or other anchoring system are listed. A storage bag is included, giving owners a place to stow the cover when mowing.
The main compromise is universal sizing. The stated dimensions may suit many riding mowers, but deck shape, seat height, steering components, and other equipment details can affect coverage. The data does not specify ventilation openings, reinforced areas, or a cleaning method, so buyers should not assume those features are present. A covered shed or larger custom-fit cover may be preferable for unusual or oversized equipment.
Riding Lawn Mower Cover is worth considering when the mower fits the stated measurements and the goal is straightforward protection from outdoor dirt and precipitation. Its strongest advantages are the coated 420D fabric, elastic hem, and storage bag; the main reason to hesitate is uncertain fit and limited anchoring detail. Choose a custom-sized or enclosed-storage solution for larger machines or harsh exposure.
Riding Lawn Mower Cover provides a listed 72-inch length, 54-inch width, and 46-inch height, making it suitable for buyers whose riding mower or lawn tractor fits within those dimensions. The cover is not automatically compatible with every model, so measuring the complete machine before purchase is essential.
Listed Cover Size: The supplied dimensions are 72 inches long by 54 inches wide by 46 inches high. Those measurements give buyers a direct comparison point, though the data does not explain whether the dimensions include extra drape or how much clearance is recommended.
Deck Fit: The title states that the cover fits decks up to 54 inches, while the description calls it suitable for most riding mowers and lawn tractors. Buyers should compare deck width and the mower's overall profile rather than rely only on a general universal-fit statement.
Shape Considerations: Seat height, steering wheel position, hood shape, and attachments can affect how fully a cover reaches the ground because overall machine geometry matters. The product data does not list allowances for baggers, snow equipment, or other accessories, so owners with attachments should verify coverage.
Storage: An included bag provides a dedicated place to store the cover when it is removed. The description also says it can be placed in a mower box, though no packed dimensions are supplied.
Riding Lawn Mower Cover is intended for straightforward placement and removal because it is a full cover with an elastic bottom hem and included storage bag. That makes it suitable for owners who cover equipment between uses, though the product data does not provide a detailed installation sequence or cleaning procedure.
Before Covering: Compare the mower's length, width, and height with the listed 72 by 54 by 46-inch cover size because correct sizing determines coverage. Buyers should also account for the deck and any attachments, though the supplied information does not specify accessory clearances.
Securing: Pulling the elastic hem around the lower portion of the mower is the stated method for helping hold the cover in place. The hem is intended to reduce wind lift, though no straps, buckles, or tie-down points are listed for especially exposed storage locations.
Storage: Place the removed cover in its supplied bag because the bag is designed to make storage easier between uses. The product data does not state whether the cover should be folded dry or how much space it occupies when packed.
Maintenance: The supplied information identifies a polyurethane-coated fabric and seamless stitching but does not specify washing, drying, or repair instructions. Buyers should confirm care guidance with the manufacturer if long-term coating maintenance is important.
Riding Lawn Mower Cover Real Limitations:
- Universal sizing: The 72 by 54 by 46-inch cover affects owners of oversized or unusually shaped riding mowers who need complete coverage.
- Limited anchoring details: Only an elastic hem is listed, affecting buyers who store equipment in locations exposed to strong or shifting winds.
- Unspecified ventilation: The data does not identify vents, affecting owners concerned about airflow during extended outdoor storage.
- Unspecified care instructions: Cleaning and drying requirements are not supplied, affecting buyers who want a defined maintenance routine.
Before You Buy, Verify These:
- Confirm the full mower dimensions and attachment clearance if your machine has a bagger, snow equipment, or an unusual profile.
- Confirm whether the cover includes any additional wind restraints if the mower will be stored in a highly exposed area.
- Confirm cleaning and drying instructions if preserving the waterproof coating is a priority.
Still the Right Pick If: Riding Lawn Mower Cover remains a practical choice for owners whose mower fits the listed dimensions and who want portable, coated-fabric protection for ordinary outdoor storage.
Pros
- The three OEM references benefit John Deere owners identifying a replacement by part number.
- The stated width and length benefit buyers who want to compare belt dimensions before ordering.
- The broad listed John Deere application range benefits owners of several 42-inch deck tractor models.
- The specified belt construction benefits buyers prioritizing the manufacturer's stated strength and flexibility features.
- The 30-day defect remedy benefits buyers concerned about receiving a defective belt.
Cons
- Compatibility is limited to listed applications, so owners of other deck sizes or unlisted tractors may need another belt.
- The product data does not provide installation directions or routing information.
- The warranty is only described for 30 days, which may not suit buyers seeking a longer coverage period.
UDC Parts GX20072 Deck Belt is best for owners of listed John Deere 42-inch deck tractors who need a replacement belt, because the product data supplies OEM references, dimensions, application lists, and a 30-day defect warranty. The main qualification is that the exact tractor and deck must match; the belt should not be selected from the 42-inch description alone.
The belt is listed as a replacement for John Deere GX20072, UC32283, and GY20570 because those references are supplied as the primary cross-checks. Its stated size is 1/2 inch wide and approximately 103.7 to 104 inches long, giving buyers useful measurements to compare with the original, though the data does not establish fit for every John Deere belt system.
Construction details may matter to buyers replacing a belt for regular mowing because UDC Parts describes aramid tensile cords, a natural rubber body, and a two-layer wrapping cover. The product data also says the belt was lab-tested for low friction and minimal wear volume, though no test conditions or independent verification are provided. Installation routing and tools are not specified.
UDC Parts GX20072 is a reasonable candidate when an OEM reference and listed tractor application agree because the fit information is unusually specific. Buyers with a different deck size, an unlisted model, or a need for installation guidance should choose a different verified belt option.
Best For: Owners of listed John Deere 42-inch deck tractors replacing a worn or defective deck belt.
Why It Fits: UDC Parts GX20072 provides three OEM references, a 1/2-inch by approximately 104-inch size, and extensive model coverage.
Think Twice If: Your tractor, deck size, or original belt number is not confirmed against the supplied list.
Bottom Line: Choose UDC Parts GX20072 when the model and OEM reference match, with the 30-day defect warranty as the stated coverage.
Buy It If: You need a John Deere 42-inch deck belt and GX20072, UC32283, or GY20570 compatibility matches your tractor.
Skip It If: You need a belt for an unlisted deck size or tractor application.
OEM References: UDC Parts GX20072 is listed as replacing John Deere GX20072, UC32283, and GY20570, though buyers should compare the original reference.
John Deere Coverage: Listed models include D100, D105, D110, D120, D125, D130, E100, E110, E120, E130, L100, L105, L107, L108, L110, L111, L118, L130, LA100, LA105, LA110, LA115, LA120, LA125, LA135, X105, X106, X107, X110, X120, X125, X126, X127, X145, S100, S110, and S120, though the full deck configuration still matters.
Other Applications: Sabo, Sabre, and Scotts models are listed, though the data does not establish compatibility beyond those named applications.
Warranty: The stated warranty provides free replacement or a refund for a defective belt within 30 days, though the supplied data gives no broader warranty terms.
Pros
- Broad stated model coverage may help owners of several John Deere mower series find a replacement.
- Included mounting hardware can reduce the need to reuse or source listed small parts.
- A grease fitting gives maintenance access, though maintenance intervals are not supplied.
- Pre-greasing may simplify initial installation, though the listing recommends greasing before first use.
- Replacement part numbers provide useful cross-checks against an existing spindle, though dimensions are absent.
Cons
- The lengthy fit list does not specify deck width, mounting dimensions, pulley details, or blade orientation.
- The listing uses fit language rather than independently verified compatibility.
- No material, bearing, rotation, load, or warranty information is provided.
Fourtry GY20454 Spindle Fit for John Deere Mower is best suited to an owner of a listed John Deere model who needs a replacement spindle assembly and wants mounting hardware included. Its greasable design and stated replacement numbers add useful purchase checks, though the listing does not provide dimensions or enough deck-specific information to confirm every fit claim.
The assembly appears designed for a repair market where a worn or failed mower spindle is replaced rather than rebuilt. The compatibility description names many LA, D, L, X, Z, E, and LT series models, including 42-inch and 48-inch tractor applications in the title. That breadth may help a buyer identify a match, though model families can use different deck or mounting arrangements, so the model number alone should not be the only check.
Fourtry states that the spindle is pre-greased and includes a grease fitting for maintenance. That gives the buyer an identifiable way to service the assembly, and the recommendation to grease before first use provides a basic starting point. The data does not specify grease type, service interval, bearing construction, or how much grease the assembly accepts, so maintenance expectations remain incomplete.
Installation convenience is another stated advantage. The package includes a blade nut, pulley lock nut, four threaded mounting bolts, and a seven-pointed star-shaped blade mount. Those components may reduce parts hunting during a swap, though the description does not explain whether a pulley, spacer, washer, or other deck-specific part is included. Buyers should compare the existing assembly before disassembly.
Fourtry GY20454 Spindle Fit for John Deere Mower is a qualified option when the buyer can match the mower model, deck configuration, OEM number, and physical dimensions. Before purchase, compare GY20454, GY20962, GY20867, or GY21098 references with the original part and verify mounting, pulley, and blade details. If any of those checks fail, a model-specific assembly with published measurements is the safer direction.
Strong Match: Fourtry GY20454 Spindle Fit for John Deere Mower is a strong match for an owner whose mower model and existing spindle correspond to the listed series and replacement numbers, because the assembly includes hardware and a grease fitting, though dimensions still require verification.
Also Consider It If: Consider Fourtry GY20454 Spindle Fit for John Deere Mower if ongoing greasing matters, because the assembly is described as pre-greased and greasable, though grease type and maintenance intervals are not specified.
Not the Best Fit: Fourtry GY20454 Spindle Fit for John Deere Mower is not the best fit for buyers unable to identify deck configuration, pulley arrangement, or mounting dimensions, because the broad model list does not provide those technical details.
Decision in One Sentence: Fourtry GY20454 Spindle Fit for John Deere Mower suits owners of a verified listed mower needing a maintained replacement assembly, provided the part number and physical fit are matched first.
Consider It For:
- Replacing a spindle on one of the listed John Deere mower series.
- Cross-checking against GY20454, GY20962, GY20867, or GY21098.
- Using a spindle with a grease fitting for maintenance.
- Receiving listed nuts, bolts, and blade-mount hardware with the assembly.
Pass If:
- Your mower model, deck, or blade arrangement cannot be confirmed.
- You need published mounting, pulley, bearing, or overall dimensions.
- You require documented materials, load testing, or warranty coverage.
Fourtry GY20454 Spindle Fit for John Deere Mower should be considered compatible only after the mower model, deck configuration, replacement number, and physical dimensions are checked, because the listing supplies a broad model list but no measurements.
- Named series include LA, D, L, X, Z, E, and LT.
- Listed replacement numbers include GY20454, GY20962, GY20867, and GY21098.
- The title references 42-inch and 48-inch mower tractor applications.
- Verify pulley, blade mount, mounting-hole pattern, and hardware before ordering.
Pros
- Includes two trunnions, rods, nuts, washers, and spring locking pins for buyers needing a complete listed set.
- Lists a broad range of compatible tractor models for buyers with one of those exact model numbers.
- Provides multiple replacement-part identifiers for buyers checking existing hardware.
- Two of each component benefit applications requiring paired deck-lift parts.
- Narrowly targeted deck-lift contents benefit buyers who need the listed linkage pieces rather than a general repair kit.
Cons
- Fit is not established for models absent from the compatibility list, affecting buyers with unlisted tractors.
- The supplied data does not include installation instructions, affecting first-time repairers who need procedural guidance.
- The data does not provide dimensions or material details, affecting buyers who need to verify physical specifications before ordering.
Huthbrother GX24864 GX21718 Deck Lift Hanger Rod kit is best for owners of the listed J-OHN D-eere lawn tractor models who need replacement deck-lift linkage because the package includes two trunnions, two rods or bolts, two nuts, two washers, and two spring locking pins, though the supplied data does not confirm fit for unlisted model variations. The kit is therefore a model-matching purchase rather than a universal repair choice.
The component count gives the buyer two of each named part because the listing specifies paired quantities, though the product data does not explain whether every tractor installation uses all included pieces. GX21718 and GX24864 appear as the principal trunnion and rod identifiers because those references are in the title and kit contents, though buyers should still compare their tractor model and existing part references.
The compatibility list includes L100 through L175 models, numerous 100-series and D-series models, E100 through E180 models, and selected X, G, and S models because those model numbers are supplied, though the list should not be extended to similar-looking tractors. No dimensions, materials, installation sequence, tools, or maintenance requirements are provided, so buyers cannot verify physical specifications from this listing alone.
The Huthbrother GX24864 GX21718 kit merits consideration when a buyer's tractor exactly matches the supplied compatibility list and the needed parts correspond to the listed identifiers, though installation guidance and broader fit evidence are absent. Buyers with an unlisted tractor, uncertain model number, or need for a complete deck assembly should choose a different product type or verify compatibility before purchase.
Best For: Owners of a listed J-OHN D-eere lawn tractor replacing deck-lift hanger hardware.
Why It Fits: The Huthbrother GX24864 GX21718 kit includes two sets of the named trunnion, rod, nut, washer, and locking-pin components, though installation details are not supplied.
Think Twice If: You own an unlisted model or cannot identify your tractor accurately, because compatibility is stated only for the supplied model list.
Bottom Line: Buy the Huthbrother GX24864 GX21718 kit when the model and part references match, though physical dimensions are not provided.
Buy It If: You need listed deck-lift linkage parts and your tractor model appears in the supplied compatibility list.
Skip It If: You need a complete deck assembly or confirmed fit for an unlisted tractor that this product cannot establish from supplied data.
Model Groups: The Huthbrother GX24864 GX21718 kit lists L, LA, numbered, D, E, X, G, and S series tractors because those model families appear in the product data, though similar names do not guarantee compatibility.
Listed References: GX21718 and GX24864 identify the trunnion and rod or bolt in the supplied kit, though the data does not provide cross-reference verification beyond the listing.
Included Quantity: The kit contains two of each listed component because the contents specify paired quantities, though the required quantity for every listed model is not explained.
Verification: Buyers should match their exact tractor model to the supplied list because compatibility outside that list is not established.
Pros
- Broad listed compatibility can help owners of several John Deere and Cub Cadet models find a replacement.
- 12V specification provides an important electrical matching point.
- Several OEM and replacement numbers are supplied for identification.
- The package includes one starter solenoid, keeping the purchase straightforward.
- The listing provides terminal-size and grounding information.
Cons
- Exact fit cannot be assumed from brand alone, so model and part-number verification is necessary.
- Incorrect wiring could prevent proper operation or cause electrical problems.
- The package contains one solenoid, and no installation instructions are supplied in the data.
- Warranty coverage and testing details are not provided.
Tecreddy Starter Solenoid is best for owners of the listed riding mower models who have diagnosed a failed solenoid and can match the replacement carefully. Its strongest reason to consider it is the 12V specification and broad list of replacement numbers, but electrical parts require exact fitment and wiring verification before installation.
The solenoid is described as a starter relay for John Deere, Cub Cadet, MTD, Troy-Bilt, and Trombetta riding lawn mower tractors. The listing provides replacement numbers including 725-04439, 725-04439B, GY22476, AUC15346, AM138068, and 862-1211-211-16. Matching one of these numbers to the original component can reduce guesswork, although the supplied data does not establish that every listed number is interchangeable in every machine.
Compatibility is extensive. John Deere applications include numerous L, D, Z, LA, and X series models, while Cub Cadet applications include LTX, RZT, CC, GT, GTX, I, LGT, LGTX, LT, SLT, and SLTX models. The component is specified as 12V, with a 1/4-inch terminal stud and grounding through the terminal. The housing and wire materials are described as ABS and QA-1/155 copper wire.
The main concern is installation accuracy. A long compatibility list does not replace checking the exact mower model, existing part number, terminal arrangement, and wiring diagram. The listing refers buyers to a detail-page wiring diagram, but that diagram is not included in the supplied data. There is no installation procedure, electrical test result, warranty detail, or customer review evidence to confirm performance.
Buy it if your mower and original solenoid match the listed application and you are comfortable verifying the wiring. Hesitate if you cannot identify the failed part or need professional installation guidance. Before purchase, compare the mower model, part number, voltage, terminal layout, and grounding arrangement.
The Good:
- 12V specification supports straightforward electrical matching.
- Multiple replacement part numbers are listed.
- Compatibility includes many John Deere and Cub Cadet mower models.
- 1/4-inch terminal stud and terminal grounding are identified.
- Package includes one starter solenoid.
The Bad:
- Exact fitment still depends on the mower and original part.
- Wiring instructions are not included in the supplied data.
- No warranty terms or electrical testing details are provided.
- Incorrect installation may cause electrical problems.
Bottom Line: Tecreddy Starter Solenoid offers broad listed 12V compatibility and several matching numbers, but buyers must verify terminal layout and wiring before installation.
Buy It If:
- Your John Deere or Cub Cadet mower appears on the compatibility list.
- Your original solenoid matches one of the listed replacement numbers.
- You need a 12V replacement with a specified 1/4-inch terminal stud.
- You can safely confirm the wiring and grounding arrangement.
Skip It If:
- You cannot identify your mower model or original solenoid number.
- You need detailed installation support or included wiring instructions.
- You prefer a part with documented testing or warranty terms.
Our Take: Consider Tecreddy Starter Solenoid for a confirmed matching mower and part number, but verify the terminals and wiring before fitting it.

How We Evaluated These Recommendations
These recommendations compare the supplied product facts, listed specifications, compatibility statements, relative price positioning, relative rating positioning, and any available customer-review signals. No customer-review excerpts were supplied for the products covered here, so review volume and review consensus were not used to support a ranking. The category criteria were model and part-number fit, deck-size coverage, component function, included hardware, stated dimensions, and the practical cost of choosing a more precisely documented replacement.
Manufacturer or merchant descriptions are claims supplied for comparison, not independent testing. A listed material, compatibility statement, warranty, or installation feature should not be read as proof of long-term durability or successful fit on every mower. Customer-review excerpts, when available, would also represent individual experiences rather than automatic consensus. Products with more concrete part numbers and dimensions receive stronger editorial support, while products with missing specifications remain conditional recommendations even when their listed applications appear broad.
Decision Criteria for parts for john deere riding lawn mowers
1. Confirm the mower model and replacement number
Model and replacement-number agreement should be the first decision rule for parts for John Deere riding lawn mowers. The Gy20680 Gx24332 Lgnition Keys Replacement identifies GY20680 and GX24332 and names D100 through D170 models, while the Tecreddy Starter Solenoid identifies AM138068 and several alternate numbers. Those details can answer a preliminary fitment question. They cannot resolve serial-number differences, connector changes, or an incorrectly recorded model. A mower manual or parts diagram remains a necessary disqualifier when the listed number does not match.
2. Match deck size before choosing deck hardware
Deck hardware should be selected only when the listed deck size matches the mower. The 4 Pack AM125172 Plastic Deck Gauge Wheel Kit names 48-inch, 54-inch, 60-inch, 62-inch, and 72-inch decks, along with a 5-inch outside diameter, 2-3/4-inch width, and bushing details. That is stronger fitment evidence than a generic deck reference. The exception is a mower with an unlisted deck or a different wheel mount, where the supplied coverage does not establish compatibility.
3. Choose the component that addresses the actual symptom
Component function should determine the purchase: keys for a lost ignition key, a solenoid for a suspected starter-circuit fault, gauge wheels for deck-height support, and a spindle for the corresponding deck drive assembly. The supplied descriptions identify those functions, but they do not diagnose a mower. A no-start condition may not be caused by the Tecreddy Starter Solenoid, and an uneven cut may not be caused by the AM125172 wheels. Buyers should rule out unrelated faults before replacing a part.
4. Prefer concrete specifications over broad compatibility language
Concrete specifications should carry more weight than broad compatibility wording. The AM125172 kit supplies wheel dimensions, bore and hub details, bushings, grease zerks, and bolts, while the Tecreddy Starter Solenoid supplies a 12V description and terminal detail. The Fourtry GY20454 listing supplies model and deck references but no additional specifications in the provided record. Missing dimensions are not proof of poor quality, but they reduce the confidence of a comparison when a buyer needs to verify a physical replacement.
5. Treat price and rating position as secondary evidence
Price and relative rating position should break ties only after fitment is established. The GY20680 GX24332 keys and Tecreddy Starter Solenoid are positioned lower in the supplied price field and higher in relative rating position, while the AM125172 kit is positioned in the middle on price and higher on relative rating position. The supplied record does not provide review counts or excerpts, so these positions cannot establish value, durability, or consensus. A cheaper part is not a safe choice when the model match is uncertain.
What the Data Does Not Resolve
- Long-term durability and service life are not documented by independent test results.
- No customer-review excerpts or feedback-volume data were supplied for these products.
- Variant-specific compatibility, including serial-number and connector differences, remains unresolved.
- The Fourtry GY20454 record does not supply dimensions, materials, bearing details, or installation hardware.
- The listed compatibility claims are not independently verified in the supplied data.
Final Verdict by Buyer Type
Buyers maintaining a John Deere mower deck should start with the 4 Pack AM125172 Plastic Deck Gauge Wheel Kit Compatible with John Deere 48″, 54″, 60″, 62“, 72” Deck Lawn Tractor Mowers Wheel Kit, AM124706, 210-300. Its listed deck-size range, series coverage, wheel dimensions, bushings, grease zerks, and bolts provide the most complete fitment evidence in the supplied set. The trade-off is that compatibility with a particular serial-number variant and real-world durability remain unknown. Confidence is therefore strong for a matching listed deck, but not universal.
Buyers replacing a named spindle should consider the Fourtry GY20454 Spindle Fit for John Dee re Mower – Spindle Assembly Fit for John Dee re LA135 LA115 LA125 LA145 LA105 LA130 D140 D130 D105 D110 L110 X110 42″ 48″ Lawn Mower Tractor, Replace GY20962, when the model and deck match. The exact replacement reference and application list support that narrow choice, but missing specifications limit confidence. Buyers who lost a key have a clearer use case for the Gy20680 Gx24332 Lgnition Keys Replacement, while buyers diagnosing a starter circuit can consider the Tecreddy Starter Solenoid because its 12V and replacement-number details are supplied. Neither electrical operation nor individual lock fit is independently confirmed.
Products With Insufficient Evidence
No product is excluded because the supplied data proves it is defective. The Fourtry GY20454 Spindle Fit for John Dee re Mower – Spindle Assembly Fit for John Dee re LA135 LA115 LA125 LA145 LA105 LA130 D140 D130 D105 D110 L110 X110 42″ 48″ Lawn Mower Tractor, Replace GY20962 receives a more conditional recommendation because the record does not supply spindle dimensions, materials, bearing information, or installation hardware. The Gy20680 Gx24332 Lgnition Keys Replacement and Tecreddy Starter Solenoid also lack customer-review excerpts and feedback-volume data. Those omissions limit confidence, but they are not negative findings about product quality or performance.

The 4 Pack AM125172 Plastic Deck Gauge Wheel Kit has the clearest deck fitment evidence in the supplied data. The listing names several John Deere series, deck sizes from 48 inches through 72 inches, wheel dimensions, bore details, bushings, grease zerks, and bolts. Buyers should still compare the mower model, deck, and existing mounting arrangement because the supplied information does not confirm every serial-number variant.
Are the Gy20680 Gx24332 keys compatible with every John Deere tractor?
The Gy20680 Gx24332 keys are not shown as compatible with every John Deere tractor. Supplied product data names D100, D105, D110, D120, D130, D140, D150, D155, D160, and D170 lawn tractors and identifies GY20680 and GX24332. The listing also tells buyers to confirm the machine model, so owners outside that range need additional parts-diagram verification.
What evidence supports the Tecreddy Starter Solenoid?
The Tecreddy Starter Solenoid is supported by a supplied 12V description, a 1/4-inch terminal-stud detail, a grounding description, and replacement numbers including AM138068, GY22476, and AUC15346. The listing names multiple John Deere models as well as other mower brands. Those facts support a preliminary part-number comparison, not a diagnosis or independent confirmation of electrical performance on a particular tractor.
Does the data prove that the Fourtry GY20454 spindle will fit?
The supplied data supports a conditional fitment match for the Fourtry GY20454 spindle, not proof of universal fit. The product title names GY20454, replacement GY20962, several John Deere LA, D, L, and X models, and 42-inch and 48-inch decks. The record does not include spindle dimensions or other technical specifications, so buyers should verify the original part number and deck assembly before purchase.
