I have a heavy and steady leak from the kotter pin hole of hydraulic fluid when the tractor is running. Additionally, my PTO is not working. This model has the independent PTO. Its hard for me to say if these two things started at the same time, however it is a possibility that they did. Fluid levels in the Trans resevoir are lower than the fill to hole, and the fluid level in the rear hydraulic resevoir is full to the fill hole. Based on my research, I likely need to split the tractor and repair the busted seal(s) in the front of the transmission. Could these busted seals have anything to do with the PTO not working? The three point hitch is working, but is very sensitive.. small movements of the lever cause large up and down movements in the three point hitch attachements (bushhog).
