Hump, the problems I have with the winch (Superwinch 1500) are it is too
strong and too fast.
Running at 36V would make it faster (and stronger?) and that would be a
bigger problem.
Already I have to use some kind of disposable sacrificial link between the
strap and the
implement so as to avoid ripping the fixture right off the implement. I
use a 1.5" or 2"
diameter split ring (keyring). When the snowblower is all the way up
against the stop and I
haven't managed to get my finger off the up switch, the split ring uncoils
and stretches so
that nothing breaks. I've been trying to brainstorm some kind of fairlead
mounted on a spring
arm so I can get a visual indication of imminent damage, but I haven't got
anything yet.
The other possibility I've been considering is some way of implementing a
limit switch, but
that would need a different setup for each implement, and has other
electromechanical issues.
Still thinking...

Since you said the winch is beefy. I would just wire it to run on 36v.
I have a small portable air compressor I bought at K-mart; it is the
"Truck-Air 125" I believe. It is designed for use on a 12 v auto battery.
I
think you know the type I'm talking about. I cut off the cigarette lighter
end and attached some clip leads. I run that 12v motor off the 36v pack,
everytime I use it. So far no problems. And let me tell you it really
moves
some air on 36v.
I speculate that the winch you have has an even beefier motor and was
designed for at least 4 times the load you will ever put on it with an ET.
Just run it off the entire pack. It'll be alot quicker too.

On a separate but related topic, currently I'm running a beefy 12-volt
winch
on the front of the tractor instead of the defunct OEM lift. I worry
that
I'm imbalancing the pack by driving it off the two front T-105s,
especially
when snowblowing or plowing when I lift the blower or plow up and down
all
the time. I wonder if I take out the OEM charger and start using a
Soneil
3610SRF instead, I can put a 12V battery in it's place and use that for
the
winch motor. Then to charge the 12V I can get a 36VDC-12VDC converter.
I
could use an inexpensive little one with low rated amps, and make sure
it's
disconnected from the circuit when drawing the big amps with the winch.
(Maybe I can use one of those self-resetting-fuse things, positive
temperature coefficient devices to protect it?) Or maybe I'd be better
off
with a separate Soneil charger for the 12V bat.
