Hey guys, I just bought a Turf Tracer Hp this week and I'm already having some problems with it. First of all, I was mowing yesterday and the mower would want to jerk right or make a circle if I were to let the controls go as if it were straight. So I turned the tracking knob to the left in 1/4 turns...this helped but it still wasn't tracking straight. I turned the knob until the darn knob came unscrewed from the bolt. I do not know if I lost some nuts or washers and such in the grass there when the knob came off, but ever since I've tried to get the knob back on and adjust the tracking, it will not track right. Having a terrible time with that. Also, my left hydro pump looks like it is leaking around the base. The right is dry, but the lefts has some seepage. Very dissapointed in my new exmark here. I was hoping I wouldn't have to have this machine at the shop all the time.
