Also found in: Dictionary.
a machine for uprooting stumps, extracting large stones from the soil, and removing trees and brush when bringing new land under cultivation, and during the preparation of routes and drainage canals.
Stump pullers are made with cable traction (winches; cable devices that operate on direct tractor traction) and with working elements in the form of teeth (hooks) that uproot by tractive or pushing force, lifting force, or a combination of forces. Stump pullers mounted on the front or rear of tractors, as well as trailer and self-propelled stump pullers, are manufactured. The most commonly used stump pullers in the USSR remove stumps by the pushing force of a tractor. They have a frame, a working element with hooks, and a lifting mechanism. During operation, the hooks dig under the stump and move it through the pushing force of the tractor; at the same time, the stump is raised by the uprooting device, or the hooks dig under the stump, and the stump is removed by the pushing force of the tractor.
