I just ordered some new Exmark spindles part # 1-634972 First I contacted my dealer and he wants $220 + tax each. Since I'm replacing all 3 this mower is 12 yrs old and has the original spindles, on a 60" Trivantage deck. I decided to first do a search online. Bam! Same part number but the price was $96.84 for aftermarket . Which one would you buy ? Is there a difference ? Obviously I went with the cheaper ones, but will they hold up as well as the originals 4100 + hrs? What would you have done? Is the Exmark dealer overpriced, the other dealer said this was his regular price?
