Lunging or Jumping

[Kevin New]

we have a 2011 M126 that lunges or jumps violently when using the clutch to stack bales, load bales, and even working in the field Mowing when stopping or taking off while using the clutch, i have seen this problem somewhere on here before but can't find where it was, has anyone else experienced this problem? when loading bales in someone's truck it can be pretty scary, sometimes it is so violent, u wonder if the transmission fell out

Don't know if it is any help to you but,
I had a car years ago that acted like that and it turned out to be the clutch disc itself. Some of the spring pieces in the middle surrounding the hub were broken and lay in the inspection cover of the bell housing.

Don't think I'd be loading anyone's truck until it's fixed. If it lurched into a newer model you'd do way more damage than the hay is worth!

What gear are you working? It can’t lurch very much in Lo-1.

Welcome to this forum
M126 parts catalog I viewed showed this model has a damper clutch plate that remains engaged 100% of the time. Therefore clutch control my guess is a hyd valve either manually or electronically controlled. Do you see any error codes? While inspecting parts diagram for shift valve I noticed a breather. Has this breather been checked/cleaned lately?
