Hello all, I have a question for you. Does anyone know what would cause my L2800 hydrostatic transmission pedal to at times be very hard to engage? Revs high or low does seem to matter that much with the problem. At times I have to stomp on the pedal to get it to engage and move the tractor forward, other times it engages smoothly. Doesn't seem to effect reversing the tractor. Thanks for any advice with this issue.
