EHSS

[Doc_Bob]

can someone go into more detail about the EHSS? how does it work? is it a cross between HST and gear transmissions? would it be ideal for disking and running a rotary cutter?

I plow, rototill and bush hog with my EHSS (power shuttle) all the time.

The shuttle lever operates electric solenoids which activates hydraulic clutch packs. Usually one pack for forward and one for reverse.
Pretty simple compared to a hydro.

I guess the newer ones are different as to the pedal. My 2120 has a conventional clutch, between the engine and the clutch packs. It's two-stage for drive and PTO.
The EHSS works great, since as Doc Bob says you can run at moderate rpm (I use the foot throttle a lot) yet still have the easy reversing. And when you're working in a field, you have the simple operation of a gear tractor.
I also rev down before reversing, to save strain on the parts, but it will reverse at full rpm. Also have a turtle/rabbit switching the speed of the reversing. I stay in rabbit most of the time.
Mine hasn't broken (1300 hrs, 1993) so I think it's swell!
