Massey Ferguson 811 skid steer

[El]

I am looking at a MF 811 that the seller states has a weak drive on one side. He is thinking the drive motor. The unit is priced right but was curious if anyone can make a recommendation on what to look for diagnose the weak drive. This way I can be better aware of the fix and cost. Thanks

I think that to use the worst case senario as to what is wrong parts wise ,then look and see if the parts are readly available to make that repair ,labor inc. and use that info. plus is this the right machine for your use. Then make your choice.
