HST Power ?

OP isn't treating the hydro pedal like a gas pedal.....right?
(i.e. don't push pedal down more as tractor slows down, instead lift pedal for the "shift to lower gear" equivalent.)
He wouldn't be the first.

THANK YOU

Good points about the linked throttle and the HST pedal not being an acceleration pedal. It took me a bit to realize that the transmission needs higher rpm to work properly and to get the feel of using the HST pedal. When working it hard I have the throttle set at PTO rpms and monitor the tach to control the HST pedal position. When the rpms start to drop I back off the HST pedal until the rpms get back to PTO speed. It's a balancing act and I have that figured out.

With the HST I can keep the rpms up but have to watch the HST pedal position in order to maintain the rpms

As you can see I have already addressed the Hydro pedal position.

There is no red line or PTO info on this tach. Basically it just shows the rpm's. I checked the owners manual and can't find the max rpm info but this tractor will only rev to about 2510 max and that is where I run it when working it hard.

FredH thanks for that link. As D2Cat suggested there must be a misprint about the drawbar HP. I wish it were true though because if it was I wouldn't have any problem dragging my little boxblade.
