The pedal is not a gas pedal. Less is more when it comes to HST, the less you press the pedal the more torque you put to the ground.

Duane and Jim: Been away for awhile so didn't see your posts. I don't have a digital camera so no pics. All I did was to cut 4 pieces of 3x3x1/4 angle (just what I had laying around) about 4" long and cut a point on one end of each. I welded them to the bottom of the pads, about evenly spaced side to side and centered front to back, kind of like this:

so they expose the most cross section to the back. Hope this helps. Would probably be pretty hard on the lawn!

So these are essentially spikes that dig in if I'm not mistaken in my reading of your description?? TYIA

Bo Man has it right. Pressing harder puts it into a higher gear. Press a little, climb a lot!

Right you are, Jim.

I have my BX22 a week now. Took the backhoe off yesterday and put on the Brush hog. Checked the transmission fluid and it was on the low line. when I raised the 3 pt hitch I saw fluid squirt out of the tractor's outlet hose that I hooked into the return pipe coupler. Will call the dealer on Monday. I am hoping it is only a bad hose. Anyone else have this problem. Have 20 hrs on the machine. rehooked the hydraulic lines to the backhoe. It's not the hose the connection on my tractor has the leak
Bill:
With a HST, you get the same torque at any speed in normal conditions. The torque delivered by the hydraulic portion of the HST is a direct function of pressure, which is set by relief valves. Some reliefs, once they open, have hysteresis which means that you must go to a lower pressure, and therefore torque, before they will reclose. This means that you have to back off the pedal almost completely before you can get full torque again. But if you are moving, you will get the same torque no matter how fast you go.
As for other theories, there is no gear change in a HST, just a pump that delivers oil at a rate set by the pedal, and a motor that spins at a speed that is a function of the oil flow rate.

John,
Just had my BX22 serviced to replace the hydraulic connector on the right side of the machine under the seat for the backhoe. Same exact problem you mentioned. Takes 10 minutes to fix. O ring in the female connector was bad. The tech said if it happens again they'll upgrade the connectors to the stronger ones used on the front loader.

It is real easy to pinch the hose that goes to the backhoe while installing it on the tractor. It might be leaking from a break in the middle of the hose.
