[AT] OT: hydrostat mowers

[Bill Bruer]

I have a Cub Cadet 1330 with the hydrostat transmission - that is, an 
integrated pump and motor unit.  Also, my zero-turn mower has 2 IZT 
integrated pump and motor units.  Neither is recommended for hard pulling 
jobs, yet both have drawbars and I see others using these type of mowers for 
pulling various implements.  The main possible damage seems to lie in 
overheating the hydro units.

So, when pulling an implement is it better for the hydro units to use full 
engine/pump rpm and reduce ground speed with the hydro motor controls or 
slow the engine/pump and open up the hydro motors?  I hope I've stated this 
fairly clearly.
