PTO Powered Rotary Plow
Kuhn's new pto-powered "all-terrain" rotary plow attracted a lot of attention at the DLG Show in Germany.
It was especially designed for use in difficult soils where traditional moldboards have problems penetrating, such as in hard, compact ground or in muddy, slippery clay soils where tractors would slip. Because the driven plow discs turn in the direction of tractor travel, it requires only minimum drawbar power, greatly reducing tractor wheel slip, according to company representatives.
The 8-ft., 2-in. wide plow works down to 11 in. Working depth is controlled by two gauge wheels. It's fitted with 8 concave discs, each of which is equipped with 5 teeth fitted to the edges. The discs measure 2-ft., 6 in. in dia. The plow can also be fitted with curved, roto-tiller type tines in place of the concave discs and teeth.
Requires a 1,000 rpm pto and the plow's gearbox has interchangeable pinions which let you vary speed of the plow rotor from 94 to 194 rpm's. Works at field speeds up to 4.5 mph. Requires a minimum 110 hp. tractor.
The company says the plow was developed in part because of new laws in Europe that outlaw straw burning. "It does a better job incorporating residue evenly into the top soil, speeding up decomposition yet leaving a protective surface mulch, reducing erosion," says a representative, noting that the new rotary plow has not yet been introduced in the U.S.
