I am having trouble with my hydros on my 08 bad boy pup 48" deck 30 hp kohler. When I am on an incline, traveling on the side of incline I lose almost all power in the lever that is closest to the bottom of the incline, the mower will not keep the hill it will turn and drive down the hill. I also have issue when I am doing a lot of zero turn type of mowing. I seem to lose power on one side( it varies from right to left side).If I mow wide open in a straight line the mower does fine. Thanks in advance.
