Disks For Sale in Canada

About Discs

Discs (sometimes spelled “disks”) come in a variety of model types. Their descriptions vary by their configurations, such as one-way disc plow, offset disc harrow, and tandem disc harrow. Discs get their name from their numerous concave, disc-shaped blades, commonly made of steel alloys. When pulled behind a tractor, the discs work to till the soil, chopping both weeds and stover (stalks, leaves, etc. left from the previous crop) to prepare the seedbed for planting a new crop. The discs can be perfect circles, serrated, or scalloped.

John Deere 2633 Disc

History

Norwegian immigrant Ole Ringness is credited with inventing the disc plow and disc harrow in Bosque County, Texas. Unfortunately, Ringness died in 1872 before hearing back from the U.S. Patent Office that his application had been approved (albeit with its fee destined to remain unpaid). The first patented disc in the United States had just one set of discs and was pulled by livestock. Eventually, more sets of discs were added, along with self-cleaning capabilities. Kuhn Krause founder Henry Krause came up with the one-way disc plow in 1916, followed in the next decade by fellow Kansan Charles Angell’s version.

As the additional speed and power of tractors in the 1920s began to cause damage to the discs when they encountered rocks and other obstacles, Roy Ingersoll developed heat-treated steel discs that could withstand the punishment. Ingersoll’s tougher steel also allowed the discs to be formed into the familiar concave shape to dislodge more soil per pass. Kuhn Krause’s Rock-Flex disc harrows also addressed the problem of stony soils in the dawning age of the tractor.

Modern Features

In the 21st Century, so-called “compact discs” with independent torsion arms instead of gang shafts spread from Europe to North America as high-speed, one-pass residue management tools.

Today, new Case IH discs for sale come in widths of up to 47 feet, have rugged discs designed to handle the toughest and heaviest crop residue, and offer more precise depth adjustment to accommodate a variety of soil types and topographies.

John Deere discs include technologies such as hydraulic folding wings for manageable transport widths; blades in a variety of sizes, weights, and spacing; and advanced bearing designs to keep the bearings free of dirt and debris.

As for individual disc coulters, Ingersoll Tillage uses a proprietary boron steel alloy with an excellent balance of hardness, resistance to fractures, sharpness, flexibility, and ductility, it says. Case IH, meanwhile, says that its Earth Metal notched blades sharpen themselves during ordinary use.
