The basic structure is a suspended, heavy V-disc harrow. It was intended for forestry use, so it had to be as strong as the tractor’s lifting capacity could handle.
We started with our super-heavy forestry suspended disc, using elements from our heavy agricultural trailed disc. The first row received tapered roller bearings with 610 mm disc blades. The massive but well-adjustable beam mounts were specifically designed for heavy-duty use.
Since we wanted a streamlined machine, there’s not much to say about the disc itself. However, this machine has an extra accessory: two BUSA Rotary Hoe rotors on each side. The disc is excellent for rough work, but we wouldn’t want to bring it close to tree rows. It can either take away or throw debris. On the other hand, the Rotary Hoe can get very close to the row, reducing the weedy strip without harming the trees, as it hoes away from the stems. It’s an ideal combination. The rotors can be hydraulically extended, so the working width of the machine can be continuously adjusted.
Experience: Excellent! The disc can turn over meter-high weeds. The tractor is guided by GPS in the middle of the row, and the operator has the capacity to continuously adjust the protective distance of the rotors using two hydraulic circuits, a little closer, a little further.
For reference, a ~5-ton 110-horsepower tractor works with the 18-blade, 1.8-meter working width implement.
