Bought this tractor used from a private seller. He failed to disclose some issues with it, but that's to be expected. Brought it home and changed all the fluids. Found the front diff was full of metal and the wheel gears were dry. Also odd that it uses 80-90 for the trans and all hydraulics. Anyway, It's run great for me and I've put over 75 hours on it in 2 mo.
Two issues... the PTO shaft fell out of the back. Found there was a missing snap ring, bought a new one and replaced and issue solved. Just yesterday I noticed it was pouring fluid on the ground, looked underneath, and the front diff cases had a gap between them letting all the fluid out. Looks like I may have overloaded the front end loader and snapped a couple of bolts. I blame that on trying to do more with the 'lil tractor than it was made to do.
All in all, it's been great, and is a real trooper. I enjoy my time on it, despite it being too small for my size. Highly recommend it, as long as you're prepared to do the gray market parts search when you do have issues.
