Great Plains Ultra-Chisel
Great Plains introduces the Ultra-Chisel, a durable, low-maintenance tillage machine designed to endure rough ground conditions for consistent field performance.
Primarily a vertical-tillage tool, the Ultra-Chisel provides horizontal fracture to fit both vertical- and conventional-tillage needs. The new piece of tillage equipment has a maximum working depth of 8 inches and is available in 9- or 12-inch spacing, with optional 12- or 16-inch sweeps to undercut weeds while minimizing surface disturbance. The Ultra-Chisel’s spring-loaded shanks have 900 pounds of trip force and 30 inches of underframe clearance.
With a rocking bolster and walking tandems on the front gauge wheels and main frame, the Ultra-Chisel accurately follows uneven ground. The walking tandems absorb shock and provide consistent main frame height and depth control. A floating hitch pivots with the tractor independently of the machine’s frame, keeping all wheels on the ground and enabling all transport tires to carry the weight of the machine.
“The front walking tandems caster, as well as float up and down, so all four sets of walking tandems are on the ground at all times in uneven terrain,” says Michael Ohnsat, Great Plains. “This takes a lot of stress off the main frame and allows the machine to remain level and maintain targeted depth.”
Several new features are aimed at increasing productivity by reducing maintenance. Instead of tapered roller bearings, the walking tandems utilize a composite, fiberglass Teflon-wound bushing, sealed with dust caps on the outside. Additionally, a five-lip, cartridge-style seal in the wheel hubs prevents contamination in the bearings.
“We used maintenance-free pivot bushings so operators aren’t spending time crawling underneath the Ultra-Chisel with a grease gun,” says Ohnsat. “With the new seals in the wheel hubs and oversize, heavy-ply tires, they’re not wasting time fighting flats. Overall, we designed it to just go to the field and run.”
The Ultra-Chisel will have a limited availability for fall 2015.
