I have a TX472 and I replaced the original winch with a worm gear. I
use a Milwaukee Hole Hawg drill to run the tower up and down. BTW, I
tried two other "lesser" drills and found them lacking in the torque
needed to lift the tower. The Hole Hawg easily runs the tower up. The
worm gear has enough drag that it won't run in reverse "on its own" from
the weight of the tower.

If I do not replace the handle, I can likely drive the tower up and down using a 1/2" low speed rt angle electric drill. If, however, the handle needs to be there and if said handle needs to be locked in place to prevent self-unspooling of the cable, then I had best find a handle...
