Wheelbarrow Dump Trailer
Henson already had the wheelbarrow, which is an industrial model with a deep bucket. He built a frame and tongue out of some old steel tubing and tach-welded a ball hitch off an old 4-wheeler to the tongue.
The dump bed rides on 12-in. tires off an old riding mower and has an axle made out of 3/4-in. round stock and square tubing. The bucket is hinged at the bottom.
A 1/4-in. thick, horizontal metal strap that’s free to pivot is welded to the trip lever and is beveled at one end, which rests on a small metal tab welded to the frame. The main part of the strap rides on a 6-in. long compression spring that’s welded to the tongue. Pulling the trip lever forward compresses the spring and causes the strap to pull away from the frame, which causes the bucket to dump. When Henson lets go of the lever, the bucket drops back down and the strap automatically resets itself.
“It works really good. I use the tractor’s hitch to raise the tongue 8 to 12 in. off the ground, which causes the frame to tilt down toward the back and completely empty the bucket,” says Henson. “Once the load has been dumped I lower the hitch, which causes the bucket to slam back down.
“I used a 3/8-in. dia. metal rod to make the trip lever and the 6-in. long spring off an old trampoline to form the handle. The spring is shaped like a handle and has a comfortable feel.”
Henson uses an early 1980’s Allis Chalmers Simplicity garden tractor to pull the dump bed. “This tractor is quite rare and has a posi-traction rear end, so both wheels always pull at the same time,” notes Henson.
