So ... I have a question about HST transmission operations. Is the power put to the ground relative to the HP of the tractor? Or, does it have more to do with the system hydraulic output? I can presume that HP in a HST would still be directly related to PTO HP in the same way that a standard or shuttle gear drive system would.
I've had both shuttle & HST, and there's a clear & obvious difference in the power to the wheels. Not enough to make me switch back to shuttle of course, but it makes me wonder...
If two different tractors, with the same engine & HST transmission are equal in all ways except the hydraulic output, would there be a difference in the "power output" to the wheels? This would apply mostly to operations like plowing, pushing snow, etc.
