B7510 Jackrabbit start

[CampMan]

I recently purchased a new B7510 Hydro. When I attempt to accelerate slowly in HIGH the tractor moves slowly at first and then it suddenly jumps forward like someone had struck you from behind. Like a jackrabbit start. It will do this eight out of ten starts, at any RPM. Same for in reverse. The dealer says that Kubota had introduced a new CAM in their acceleration control in their B7510 & B7610 models and the sudden acceleration is common. ANY OWNERS OUT THERE?

Yup.

I have a 7610HST and usually only run in low but this has happened to me especially when I try to creep. You will get used to it. I just start off at lower revs.

New 7610 purchased in June.
I get a bit of it in high range but never jarring. I got used to it pretty quick but would have to say that there's not a lot of middle ground in the pedal in high.

If you don't get used to it do the prudent thing....report it to the dealer while still under warranty IN WRITING.....CYA
