(ET) Lift motors

[Jim Coate <jbc coate org>]

I've been having some problems with my lift motors, both front and rear.
They will work for a bit then give out, but by waiting a while (few
minutes to few hours) will always start working again. Is this a common
problem?

I've heard these are really 12 Volt automotive power window or wiper
motors being pushed to 18V and 24 Volts repectively... is there some
sort of internal thermal overload that is tripping? Or should I be
looking for something actually broken?

And has anyone built a better lift system use bigger 36 volt motors that
can take abuse? I have a tiller on back and a plow blade on front... the
system is pretty good for breaking up the ground and leveling things
off, but there is a lot of demand on the lifts.
