I picked up a winch that I'll be using to pull dirt out of my
basement. So now I need to power it.

It is a one horse motor- 2000lb capacity.

I'll be using it to pull a [roughly] 300pound load up a wheeled
incline for 20 feet--- then it will rest for 30 minutes or so-- then
repeat. Probably not more than 3 times. . . then do it again
tomorrow.

So I won't be working the thing real hard. What are some thoughts
on how to power it.

I've thought of a marine battery- and trickle charge overnight. I
have the charger. Would have to buy the battery.

I've thought of a transformer. Have no idea what size or what they
cost.

I've got an old riding mower with a bad transmission. Seems like
overkill, but it has a good 8hp motor on it, and charges the little
battery - so I think I could just run it off that battery when the
motor is running.

Or I could pull the Impala around to the side of the house and tap
into that 12v system.

What sounds like a feasible plan?

Thanks,
Jim
