I believe it is the style just before your style. The difference in the decks is how they mount. I would think that the spindles would be the same but I'm not 100% sure. The spindle is working fine for me. **Q: Have a John deere G335 with 54 inch deck.dose this fit this fit** A: yes AM121229 for 54 mower deck parts for 335 AM144377 for model 54C mower deck parts for GX335 **Q: Will this fit a John Deere 425 with a 54" mulching deck? Looks identical** A: That is the correct model and a direct replacement for a 54" deck on a 425 Garden Tractor. This spindle is also interchangeable with AM115528 & AM121229. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice product *by N***M on May 11, 2024* When I ordered it I wasn’t sure if it was the right one. It fit perfectly and it was great this one had carriage bolts which made installation so much easier. ### ⭐⭐⭐⭐⭐ Exact for 757 *by R***R on May 17, 2024* Good quality ### ⭐⭐⭐⭐⭐ Quiet mowing after 40+ pumps of grease *by S***C on August 9, 2023* I bought 3 spindles after one froze after 30+ years of use. These came with zirk, bolts, washers, and lock nuts which appear to be stainless (except the zirk - sink coated). The bolts are longer than the originals but they do not interfere with operation. I read a review that stated that each spindle took 40 pumps of grease each and they were right; it took me around 40-50 pumps each as they are not packed from the factory. For the price compared to OEM, I didn’t mind adding the zirk fitting from the box and the grease. After adding the grease, the bearing is hard to turn so after assembly, I turned all of them by hand to loosen them up as not to bind the belt. I was amazed at how much quieter the mower was during operation. I guess I got accustomed to the noise and should have greased the old spindles better. I plan to update if these new spindles fail prematurely but impressed so far. ## Frequently Bought Together - q&p AM121342 Spindle Assembly Bracket 54-inch Mower Deck Parts for 335 Replace John Deere AM121229 AM121342 Oregon 82-333 Rotary 11278 285-109 with Zerk Fitting for 48" 54" John Deere Decks - HD Switch - 3 Pack - Blade Bolt for John Deere 19M7788 12mm x 25mm ID - 10.9 Grade - Made in USA - MaxPower 561809B 3-Blade Set for 54" Cut John Deere Replaces M115496 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/186606788-q-and-p-am121342-spindle-assembly-bracket-54-inch-mower](https://www.desertcart.co.th/products/186606788-q-and-p-am121342-spindle-assembly-bracket-54-inch-mower) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-03*
