In another post the term power wagon came up and it reminded me of the huge
rock pile I must move this spring. I've been wanting a walk behind self
propelled larger than normal garden variety dumping wagon for a while.
Anyone have plans already available BEFORE I start searching. I've got a few
spare B&S and Honda engines salvaged from dead generators and lawn tractors
and would like to build one fairly soon.

This is what I would like to do with it.

1) self dumping bed...flip a switch / valve and rocks on the ground
2) carry at least 700 lbs some of my rocks are over 100lbs each and it's a
ways from the rock pile
3) Forward / Reverse and a positive braking system..Sometimes I'm on a hill

Doesn't matter if the propulsion is mechanical or pneumatic except I would
like the cost to be as low as possible

Anyone have plans online??

Thanks
Pedroman
