New Style Disc Is Free-Floating
The machine also features slanted disc gangs in place of the V-shaped design found on most machines. The slanted gang design shortens up the machine and means that no matter how wide it is built, the length remains constant.
"There's no other disc on the market with as much flexibility. It flexes in all directions and does as uniform a job going over hills and into low spots as it does on flat ground," says Carpenter.
The new disc can be built in any size from 12 ft. wide and up. The 18-ft. model has three 6-ft. sections, each with two disc gangs. Each outside disc section flexes as much as 18 in. below the horizontal and all the way up to the vertical position for transport.
A key feature of the new disc is its completely free-floating tongue. "A frame which holds the tongue to the main frame of the disc releases when the disc is lowered to the ground, allowing the disc to float independently of the tongue and tractor. The result is that, unlike conventional discs which pull out of the ground when going over a hill, this disc is free to follow the tractor independently. When the disc is raised, the frame again stabilizes on the tongue for transport," explains Carpenter.
All disc gangs are slanted. The front gangs on each section throw dirt one way and the rear gangs throw it the other way. Because the design is uniform on each section, the machine can be built to any width and without getting longer, unlike discs with V-shaped gangs which get longer as they get wider. The disc can be used as a heavy offset disc by lowering it all the way into the ground or as a finishing disc by running it shallower. Carpenter pulls the 18-ft. model with a 125 hp. tractor.
"We have found that even farmers who operate on relatively flat land are interested in the new disc because of its compact design, and because most farms, no matter how level, still have uneven areas," says Carpenter, who has formed a company to build and market the new disc.
