He Built His Own Heavy-Duty Bush Hog
Morris operates an automotive shop and built the 3-pt. mounted machine in his spare time and on weekends. “Customers who came into the shop were shocked when they saw what I was doing. They had never heard of anyone building their own bush hog,” says Morris. “I looked at several different brands before I built it, and decided to build something heavier. I used it for the first time last spring with my Massey Ferguson 1135 2-WD tractor on about 300 brushy acres, and it worked great.”
He says he did a lot of mig welding and used a lot of 2-in. square tubing and 3/8 and 1/2-in. thick steel to build the machine. “It weighs at least 2,500 lbs., whereas most commercial models of comparable size weigh up to 1,800 lbs.,” says Morris.
His cost for metal, a gearbox, blades and stump jumper was about $2,600. “I saved a lot of money because if you figured in the labor and cost of materials, it would cost about $6,500 to build one. A new bush hog of comparable size sells for about $8,100,” says Morris.
Power is provided by an 85 hp. gearbox welded onto a 1/2-in. thick round steel plate. “A lot of commercial bush hogs rust out around the gearbox, and the steel plate will help keep that from happening. Also, the gearbox and shaft absorb most of the blade’s cutting force, and the plate provides reinforcement.”
A stump jumper is attached to the bottom of the gearbox, and the blades are bolted to it.
The top of the deck was made by welding together a pair of 4 by 8, 3/8-in. thick steel plates and then cutting them down to 7 1/2 ft. wide. Each side of the deck was made from two 5-in. lengths of 1/4-in. thick channel iron, covered by 11/32-in. thick sheet metal. “I spot welded the sides to make them look like they’re riveted on,” says Morris.
The front part of the deck is reinforced by a pair of welded-on, 2-in. sq. tubes and also by a pair of 4-in. wide, 1/4-in. thick flat steel bars. The vertical support mounts for the 3-pt. hitch are made from 2 1/2-in. square tubing.
The arms that support the caster wheels were made by sliding lengths of 2-in. square tubing inside 2 1/2-in. tubing and then welding the tubes together for strength.
