I have a Gravely 34Z and the hydros are very sensitive. I know this is supposed to be a good thing but, I wanna lessen it. If I hit a decent bump it will cause me to hit the lever harder. The hydros on these things are strong. you can do a willy by just pushing both levers forward quickly. I think if they could be turned down It would help me have more control and possibly save the life of the pumps and motors.
