For one reason a hydrostatic drive is much more smoother, and it does
adjust itself automatically according toload on a lot of models, but
its by applying more pressure, and no difference in shifting is felt
as it does not shift, it just applies more pressure for more torque
when needed. Put it in drive and go and forget about everything else.

That is called the governor and it is on the engine, not the
transmission. The governor keeps the speed of the engine constant. All
tractors have engines where the speed is controlled by a governor. The
throttle just adjusts the spring on the governor.

Bullshit again dude.....my engine is run at a constant speed, as power
erequirements change the flow out of the hydrostatic unit is changed
automatically , similar to a auto tranny would use that to shift gear
ranges, and only when I get it really loaded down does my engine rpm
change. You can even atch the governor linkage it does not
move.,..........so now I guess you will tell me its out of
adjustment.........Perhpas on a cheap assed Murray or Stanely that may
be how they woprk but the Cub Cadets and JD and Kubotas certainly
don;t

That is what a governor does, it maintains the speed of the engine
constant. When there is a heavy load, the constant speed is putting out
more power so the engine needs more power. That works the same with a
standard transmission or a hydrostatic. No difference.

I agree the governor holds the engine at a preset speed, and prevents
over reving, but on the hydro I have that motors governor does not
fluctuate and the hydro will vary in ouotput all due to its load
governed by a pressures senseing valve in the tranny, that
automatically adjust hydraulic flow independant of engine
speed..........do your homework!
