## Questions & Answers

**Q: does this fit the 54 inch deck on the John Deere f725?**
A: I bought it as a spare but have not yet had to use it.

**Q: Does this fit JD gx345 54 “?**
A: I used it on the older style 54" deck. 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.
