You're probably researched and seen the posts 'bout all the post purchase flushing and bolt tigthtening. I did a crate JM-354 Jinma. 1st thing convert that little fuel tank shut off to a standard 1/4" needle valve so some fuel can get to the engine. 2nd thing convert the hydraulic suction filter to a screen of somekind, there's different style on this. I don't know of the exact differences between the 3 machines one of the posting venders here can fill in there, but, as far as getting my moneys worth for a useable 4 wheel tractor it's been a great investment. I have spent serious money on 3pt attachments for it also. I didn't get squat as far as a warranty, didn't need it and didn't want it. I surely didn't want to pay for the extra big name dealer overhead either. With the chinese tractor I bought as soon as the vender got the check in his hand it was my tractor and my problem, I knew that and it was okay. I use to turn wrenchs for living so maintenance and repair didn't scare me. My vender did send me some hood bracket parts for free, to be fair. I've had my tractor coming up on 5yrs. maybe 1000 hrs on it. The one thing I credit longer no breakdowns period is I didn't get a FEL on this tractor. I won't belabor the point but in MY opinion the FEL has cause a lot of grief for people. This is just snapshot kind of a review. bjr
