Hey Folks, As always, thanks to all that mke me look smart. We have a JD 110 backhoe that travels fine when you go slow. As you increase the throttle, it starts to jerk (i.e., pull and then not pull) as if it is dropping hydrostatic pressure. Has any one ever heard of this? Thanks again to all!!! Chris Lennon
Sounds like a speed sensor. They are known to go bad. They are on the right hand side of the engine toward the rear. They tend to go bad in cold weather. One way to check them is to heat the sensor up with a heat gun while it is installed in the engine and see if it drives fine when it is warm. The replacement is about $100 and change if I remember right. There is a 2 wire harness to it and it screws into the engine. Easy replacement.
Bob, You the man! Thanks for the help. I'll let you know if that does it. Chris
