I have a Ferris 1500, 52"deck w/750 hrs. The mower is leaking hydraulic fluid from inside the left rear tire. After having all the hoses replaced, it is still leaking. Took to another person, took the wheel off and you can see the fluid dripping from between the brake drum and the hydraulic motor. We tried to take the front part off just to see if it is the seal that's the problem but it wouldn't budge. In the parts manual, it does show that it comes apart. Called the dealer and he said no, we have to buy a new motor for $600.00!!! Has anyone had this problem?? What did you do?
