New rotary harrow won't plug in stubble TILLAGE EUIPMENT Harrows 14-5-26 A new-style "rotary harrow" equipped with steel spikes lets you incorporate herbicides in heavy stubble without plugging and leaves plenty of standing stubble to prevent soil erosion, according to Brandt Industries Ltd., Regina, Sask.
The harrow consists of a series of discs each with eight 6-in. long steel spikes ex-tending from them. Each set of teeth is mounted on steel plates and mounted on a steel shaft. Depth is controlled by hydraulic cylinders which also fold the harrow back-ward for transport.
"It does a consistent job over its entire width and can be used in a variety of soil conditions," says Peter Dittman, vice president of marketing. "With the trend toward soil conservation farmers want a harrow that can be used in standing stubble to prevent soil erosion without plugging up. Spring tine harrows tend to plug up in trashy fields, but the spikes on our rotary harrow walk right through. They pull straw and weeds out of the ground and leave them on the surface.
"The harrow works great when pulled behind an air seeder because it levels the ridges and removes the weeds leaving weeds and straw on the surface. It also does an excellent job of breaking hard crust on the soil surface, and it does a much more efficient job of incorporating chemicals than a spring-mounted harrow because the rotary spikes stir the ground so well. In addition, the spikes leave small craters in the ground which reduce water runoff resulting in bet-ter water retention. They deflect out of the way when hit by rocks. The bolt-on spikes can easily be replaced."
Harrow requires 2 hp per sq. ft. Models available in widths from 40 to 70 ft. A 50-ft. model sells for $15,000 (Canadian).
