Backed up to tree and it just spun tires did not stall out but it also is not under the same load because it is not trying to go as fast if that makes sense. It will bog down in forward on a uphill incline no matter where the hydro pedal is so I don't think I am pressing pedal to hard. I checked the hydro fluid and it is clean and to the full mark but the gear box does get very hot. It will cut fine on flat ground but the slightest uphill incline and the blades will lose power to them and barley spin and if I let off the forward pedal they speed back up and are fine till I pick up speed and slow down again. Checked entire deck and it is a ok. I am thinking it has to be in the carb or linkage to the carb just dont know what and how to check it. Only other thing that could be robing power is the hydro rear gearbox and I know nothing about it either.
