I bought the tractor new. It has the old style axle, is definitely a work horse, but has also had its share of issues.
Tie rod ends that hook to axle cylinder fail frequently.
6 lug bolts on rear wheels not enough when running R-1 AG tires, too much grip transfers to too much torque for wheel bolts while tractor is pulling or grading. I have to constantly keep and eye on them and carry a socket to tighten occasionally when out in the field. When under warranty the dealer said the axle bolt/lug holes were bad and replaced axle, I brought the tractor home and the new bolts started becoming loose while grading.
There's not enough room between seat and levers and seat belt. The hood, grill, and side grills are all separate and are a pain when servicing,one piece lift up grill/hood would be better.
The hydrostat pedal inkage sticks and I have to crawl under tractor occasionally and spray with lube or the forward pedal becomes very stiff and catches a lot. The cruise control also quit working.
The axle differential lock has quit working twice and I will not repair it anymore. It's not worth the money spent when it will not last.
Throttle accelerator will not stay in a hold position when cold out, I have to constantly keep bumping back up when trying to keep engine RPMS up until tractor is warmed up sufficiently.
The thermistor failed 2 different times--trouble starting happened once while under warranty and started was worn out before John Deere figured out the problem.
I have a 4 in 1 bucket which is great..
