## 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.
