My 1811 has been giving me heck lately. Ever since I converted it from an 1810 to an 1811 it has been performing strangely. When driven at first it seems normal, until it warms up, when the neutral zone grows and the tractor jerks when transitioning from forward to reverse. It also makes an odd vibrating noise when moving from forward to reverse. I welded up and re-drilled the 5/8 hole in the triangular shaped part of the linkage to remove excessive play and shimmed it with a washer. This didn't fix the problem. I can't seem to get neutral in the right place anymore, and at idle the tractor won't move in either direction, at partial throttle settings when you slowly move the hydro lever forward it does nothing and then all of the sudden jerks and abruptly moves forward. At full throttle the neutral zone is much smaller but it still jerks. I have read the FAQ's and am totally stumped. Anybody got any ideas or had a similar problem?
BTW, I didn't change the hydro pump, it already had a ported pump for some reason. I just changed the implement relief valve spring.
