Heavy-Duty Pull-Type Tile Plow
I recently brought to market a heavy-duty pull-type tile plow I've been building since 1990. It's built to take punishment. It weighs 5,700 lbs. and, at 2,200 psi hydraulic line pressure, delivers 100,000 psi down pressure on the plow. It has 1100 by 22.5 truck tires mounted on 3-in. dia. stub shaft axles. One big advantage of my pull-type de-sign over conventional 3 pt. hitch models, for example, is that when you're running 4-ft. deep, you've still got 2 ft. of room for crop residue clearance, meaning you can trench right into standing corn stalks without any pre-ripping. Maximum tile size is 5-in. dia. You can put 5-in. tile 5 1/2-ft. deep and can still get 5 ft. of cover. In the transport position (you can pull my plow behind a pickup with a heavy-duty hitch at highway speeds) the plow is 12-ft. long and 9-ft. wide. It sells for $7,000.
