Does anybody have plans for a brush hog type mower to pull behind a
four wheeler? I wouldnt be cutting brush, just rough grass, not my
front lawn. I have seen a few in catalogs but not in person. I have a
16HP B&S motor to use, some wheels for the back. I would have to buy
or make blade spindle housings, and blades. I was looking at a Ferris
mower at work the other day. It looks pretty rugged, but I couldnt see
the spindle housings. Does anyone have any advice on this subject? Any
help would be great.
Thanks,

Greetings Craig,
I have a "Bush Hog". It even says that on the machine. It has a
gearbox on top that is a right angle drive. Max input speed is 540
rpm. The gearbox turns a large disc (about 2 feet dia.) that in turn
has blades affixed to it. These blade are mounted on piviots. I
believe they are 1" dia.. The blades are thrown out by the spinning
disc and will fold back when encountering immovable objects. If I was
you I'd get a used one and adapt your motor and wheels to it. You can
pick 'em up pretty cheap used. I beat the hell out of mine and it
keeps on cutting. So getting a used one, if the gearbox and bearings
are good, will provide you with a ready-made platform for all sorts of
weldments to bolt your motor and reduction gear to. And making blades
would be tough. Look at some and you can see why. Not saying it can't
be done but you may be able to spend your time better.
