which is better - used Japanese tractor iseki, kubota, janmar or new Chinese compact tractor ?

They are at the same price ?!

Depends on how you define better. The Jinma is stronger than any of the Japanese tractors because it weighs a lot more and has better traction. This is important of you are pulling box blades, landscape rakes, finish mowers, etc.

If you're looking at it as a TLB, the hydraulics are weaker. However, a used Allmand TLB535 is a much better digger than aything that you've listed, however, it is a dedicated TLB, not a a tractor with attachments.

The Jinma requires that you turn a wrench.

I see, Jinma have a lot of "small", cheap problems which don't stop tractor work.

Interesting how long last Jinma engine, gear box, how much motor hours they can work without rebuild ??

[Jinma224]

I don't know how long they will last, I know that I have over 500 on mine, but that is a sample size of one, and I make sure that all of the preventative maintenance gets done on time.

Good job of explaining how things work under there. But, how did the drive balls disappear in the first place?

[Jinma224]

The ball socket joint is the weakest part of the 4WD system. If you bind it up (usually done on dirt with a full FEL, there is incredible pressure on the joint, the balls are pushed against the circlip until it deforms and pushes back. The balls then fall out into the rubber cup. Most of the time, it just needs to be reassembled, however, the cup and and of the shaft can be mangled enough where they need replacement. Mine are a little banged up, but fnctional.
