Rotating Disk Plow Changes AngleYou've never seen anything like this new tillage machine that's got a disk gang mounted on a circular track that rotates to any angle as needed to do everything from light disking to deep plowing.
"I've wanted a plow that would eliminate the dead furrows left by conventional 1-way plows. Two years ago my sons and I built this prototype which lets you go back and forth across the field, reversing the machine at each turn," says Alfred Korf, Yuma, Cob.
The machine consists of an 18-ft. disk gang suspended by 8 heavy-duty carrier bearings from a circular track. The gang turns on a 3-in. spindle at the center, adjusting to any angle on-the-go so it can be operated straight across for ordinary disking or tilted to the right or left for plowing. Depth and side draft are controlled by four wheels, each of which hinge up and down, controlled by individual hydraulic cylinders. Two additional wheels at the center of the 10 by 18-ft. frame lift the machine for transport.
Korf's prototype is fitted with 20 24-in. dia. discs spaced 11 in. apart. "It'll work at depths from 3 to 11 in., depending on the job. It could be modified to handle larger disks to work even deeper. Because of the way you can change the working angle on the go as needed, you can easily adapt to changing field conditions. In many cases, this tool is all you need to prepare a field for planting."
A single 3 by 24 in. hydraulic cylinder rotates the disk gang on the center spindle. Each depth control wheel is fitted with a 4 by 8 cylinder and there's a 3 by 8-in. cylinder on the hitch for leveling. The machine can be operated off two remotes. The frame of the machine is made out of 4 by 8-in. sq. tubing and the disk gang is fitted with 9 heavy-duty double row triple seal ball bearings.
"We use it ourselves so we built it to last. Because of the versatility of this machine, we think it will catch on with farmers all over the country and around the world," says Korf, who's geared up to build the plow and is also looking for an established manufacturer.
