My TZ25DA with 220 HRS has a problem. The three point hitch goes down on it's own with the tractor running. For example, If I go to carry my back blade, I will put the three point hitch up all the way and the blade will be hitting ground by the time I get to the other end of the property...(1000 feet?). Anybody experience this? This is just after I had to change a front axle seal and bearing. Oh, my fender is cracked under the seat too, but I have a Sims cab on it.....Here we go......Thanks to any replies....
