Just sold my 8N of 21 years, now I'm looking at a used JD 4310 w/loader (2003). It has 1085 hrs and is out of a rental fleet, It has some cosmetic damage, hood is cracked, needs new grill, adjustable top link is bent. I priced everything from the local dealer at around 750.00. I drove the tractor and operated the bucket, it all seems to work fine, however both front and rear rims on the inner side and on the right side of the tractor (looking from the rear) had what appeared to be dirty grease up around the axles. Is this leaky seals and why would it be on one side, this also is the side the link is bent on. My main use is cutting a 3 acre pasture with a 60in. BEFCO mower deck and moving gravel and mulch around the house. Its priced at 10000 or should I look for a 790, I'll put around 300 hrs a year on what I get. Just wanted some advice.
