[AT] OT(?) Cub Cadet 1812 Hydro question

[John Wilkens]

I got in on this string late but thought i'd throw in a little tidbit 
on hydrostatic drives.  My cub cadet has dual hydro motors on each 
rear wheel for the zero-radius turning (really like it!), but I have 
experienced one problem.  I got to working it pretty hard last week 
and experienced an increasingly loud growl (not the blades).  It got 
worse and finally just wouldn't go.  The motors are sealed.  The 
problem was the hydraulic oil in the sealed units got so hat it 
started cavitating--fomed up).  I let it sit for a day to cool off 
and it was fine.  The mechanics had never experienced it before.  I 
like the concept of zero-turn but if I had it to do over I'd by a 
Toro zero mower.   JOhn W.
