I'm considering building a brush hog; the kind you pull behind an
ATV. *It would be modelled after the Swisher Trail Cutter, which has a
single blade/rotor, 44" cutting width, and 14.5 HP engine. *According
to Swisher's parts diagram, the engine has a 4" pulley and the blade
driver has a 10" pulley (give or take a fraction).
I'm looking for a used 15 - 18 HP engine for my home built machine.
They pop up on craigslist often enough. *I'll buy Swisher's blades.
One area I'm not sure how to construct is the blade drive shaft, hub,
bearings, and pully assembly. *I'm thinking of using a 1 inch keyed
shaft with two flange-mounted bearings, one above and one below the
deck.
So one question is: Does a 1 inch drive shaft seem strong enough?
I would also appreciate a tip on where to get a hub that will attach
the blade to the shaft, or some other means of doing that. *I am not a
machinist, don't have a mill, so I can't fabricate my own hub. *I do
have a drill press, angle grinder, welder.
Thanks.
Swisher probably sells the hub assem. as a replaceable item.

I looked into it. The Swisher parts are VERY expensive.
