Ok I have lived with this for a couple years so now is the time to fix it! I have a 2004 Kubota B7510 HST and the the 3ph drifts down all the time! It doesn't matter if I am driving the tractor or if it is sitting running while I am doing something else. doesn't matter if it is at idle or full throttle. I have even been going down the road and tried to lock it in the up position with the knob in front of the seat. I am thinking it might be a seal on the lift cylinder. Any thoughts?? Thanks, Ken.
