3 point lift jerky on Kubota M6800?

[Mseriesfreak]

I just bought a 02 M6800 2wd cab with 1900 hrs.I hooked my heavy JD609 bushog to it yesterday and when you raise it up it is pretty jerky.The rotary cutter is 6' and is very heavy.I can pull in and out on tractor PTO shaft about a 1/4"Is this normal?

a jerky 3pt on an M series never heard of that as far as the pto shaft that not normal at all

I think 1/4 " movement of pto shaft is OK. Have you changed hyd filter since you purchased tractor? If so how long ago?

 

[Mseriesfreak]

I have not changed the filters.Does the valve under the seat have anything to do with my problem or it is just for lowering the speed of 3 point hitch?

It is just for the lowering speed of the 3 point hitch.

It is just for lowering the speed of 3 point hitch.

It is just for adjusting the speed of fall of the 3ph.
