I found a factory refurbished Milwaukee Super Hawg for a reasonable price on 
eBay...

Hole Hawg = 7.5A, 350/1350 rpm 
(http://www.milwaukeetool.com/power-tools/corded/1675-6)Super Hawg = 13A, 
450/1750 rpm (http://www.milwaukeetool.com/power-tools/corded/1680-20)
It easily drives the K2550 two winches on my UST TX-472 w/ big F12 C-4XL yagi + 
mast.
A bonus is, I can bore any size hole in ANYTHING. :)

The multisection boom on the yagi allows me to remove two sections and tilt the 
tower
completely horizontal. All antenna work is done with both feet on the ground.

At $158 it's certainly worth trying. That's a lot less than the dayton.
The nice thing about the Dayton was you could let go of the handle with 
no worry.  The Fulton with the brake?
It's still worth a try.  However, as the tower is vertical, I think I'll 
use the Dayton to tip it down and then try the fulton to raise ir and 
compare the forces. I think thats the safest approach.

As far as exposure a cover is easy to build for a winch like that..

I still need to get the rotator, mast and tilt plate installed as well 
as the control box for extending and lowering the tower when it's 
vertical.  Because of the tower placement, I'll need to extend the tower 
8 to 10 feet when tilted over.  I think two tilt plates with the C19Xr 
plus the WARCt might be a bit much for this tower

Thanks es 73
