I might suggest you start by check to see if the unit is displaying any error codes. Your manual will tell you how to check for codes through the dash controller. If you do not have a manual you might check the small 'reference guide' that is tethered to your interior firewall in between the seats as I believe it is outlined there as well. If you don't have a manual you can post the error code here and I will look it up for you. It is important that you include which series (A, B,C,D, & F?) Toolcat you have.
It's not throwing any codes, Bobcat says its probably the button in the control panel,1200$ I traced the wireing, all plugs were good, guess it could be the throttle position sensor , it's a D series, just under 1000 hours,probably put it in the shop this winter,, thanks for the reply! I guess this is an uncommon problem,,,just those gremlins!!
