HST tranny details?

[davesisk]

Hi folks:

I'm a current Power-trac owner (<A target="_blank" HREF=http://www.ipass.net/~davesisk/tractor.htm)>http://www.ipass.net/~davesisk/tractor.htm)</A>, and it's completely hydraulic drive, HST pump and hydraulic wheel motors at each wheel, no gear lever, etc. One disadvantage is that you only half one speed range, although it's certainly nice to not have to shift between forward and reverse (you just press the right or left pedal).

I'm curious about how the HST tranny's work on a more traditional CUT. On the JD's, is it setup with a hydraulic pump that drives a single hydraulic motor which in turn drives a geared transmission/differential/etc? Do you have the right pedal = forward/left pedal = reverse deal (or similar) but also a clutch and gear range shifter? Any details appreciated...

Thx,
Dave

It depends on the model with regards to the pump. Most of them have a forward/reverse pedal that you push. You also will have three gear ranges as well. There is also a differential lock on them.
