Bought the tractor new. The engine has been trouble free. Transmission often grinds when shifting gears and has run rough from day 1. After 5 years the plastic body parts became brittle and started falling apart.
Unscheduled maintenance items and approximate hours when they showed up:
25 hours: Bad fuel injector, fixed under warranty.
200 hours; selector started popping out of "B" range, had to hold the lever in position by hand to use "B" range.
300 hours: plastic surround for the range shift lever broke allowing lever to move past the "C" position, causing the lever's internal linkage to disconnect from the transmission and requiring a visit to the repair shop to fix.
350 hours: all plastic cover parts (hood, grill, sides) around the engine compartment started becoming brittle and proceeded to gradually disintegrate over the years.
350 hours: 4 wheel drive lever refused to engage.
350 hours: diode block (V1) in fuse panel failed, replaced block.
400 hours: brakes started not releasing after being applied, was able to temporarily fix by adding a spring on each side to release the brakes when I release the brake pedals.
400 hours: differential lock stopped working.
450 hours: seat's shock absorber failed, replaced seat and shock absorber.
450 hours: clutch safety switch failed, bypassed switch.
