Sounds like a close call. It's good to hear nobody was hurt and your PT wasn't damaged.
I haven't seen the new hydraulic treadle controls, so I don't know how much more sensitive it is than the old cable model, which I have, but I'm not sure that what happened to you isn't more a function of the PT's steep learning curve than a sensitive treadle.
PTs treadle control is quite a bit different than anything most of us have experience with. There is no dedicated brake pedal to stomp on in an emergency, but when things get sticky, there is a tendency to stomp on whatever is there--and the only thing there is the treadle. 50/50 chance on which direction you shoot. /forums/images/graemlins/crazy.gif It is a purely ingrained habit we pick up when we learn to drive.
The most difficult part of learning to operate the PT is to unlearn that brake stomping habit while on the PT, yet retain it for those times when some clod pulls out in front of you in traffic. It takes some real seat time and engine hours, at least it did for me.
I would suggest that you contact Power Trac and talk to them before you do any modifying of the controls, which might void your warranty on those parts. For one thing, if the new design is a problem in the field, they need to know that, so they can address the issue properly.
You could also discuss with them exactly what it is that controls the treadle's self centering mechanism and how it might best be adjusted or changed.
Good luck, and tell your daughter she is now a member in good standing of a fairly large club. /forums/images/graemlins/wink.gif
