Bolens QT17 bucking
Posted August 11, 2010 - 07:37 AM
I have noticed that there are a few posts on the net concerning bucking or jerking hydro on Bolens QT's and similar. Well, now I have the same issue....violent bucking at just about any speed other than full. I have tried lifting the wheels and running the tractor backwards and forwards to remove air but that helped slightly. I also changed the fluid and filter. Any suggestions?

I'm not too familiar with the hydro's....

Does the fluid get foamy? If not we may have to look elsewhere.

Thanks for the response. No foam. I am trying to think of where it could be sucking air from. Bad check valve or seal? Nothing is leaking. Where would you start troubleshooting ducky?

If so Here is a link to the service manual.

Use these in most Masseys as well.
Never had this symptom before.
I would take a close look at the linkage and be sure it is not loose or sloppy. I think the swash plates could move at will if not held in place.
I say this because it will go away at full speed and you linkage would be able hold the swash plate at full travel.
Let me know.
