Go to the chinese tractor section of this board and say that!!!!Kinda kidding,,kinda,,,but why not???,,,,I guess the question would be,,,how does a jinma compare with the others you mentioned??,,,don't know,,,,the jinma is new,,right,,don't know about others,,,,,,and a jinma is not a grey model tractor,,nothing grey about it,,,,perfectly legal to sell here brand new,,,,,,parts is NOT a problem,,,thats a lie that never wants to go away,,,,,,as far as quality,,well,,just read this board under any make,,,plenty of problems to go around on all,,,but some cost twice as much as the jinma,,,and still have problems,,,,,,,,,I got about 400 hrs on my 254 jinma now,,,not one single problem other than a couple minor leaks,,so,,,another lie,,,,,,,,,,now having said all that,,,,I don't think any 25 h.p. tractor is suitable for a lot of heavy duty dirt moving,,,they are tractors not backhoes or dozers,,,if you are going to put a hoe on it and front end alot of dirt,,you ought to think bigger than a 25 h.p. tractor,,,thingy
