The machine is designed to streamline and speed up the work carried out before the harvest season and after it. The undercutter consists of three segments: a supporting frame, a drive section and an operating section. The device is mounted on the front with a three-point mounting category I or on the rear three-point linkage system, after dismantling the beam. The machine is equipped with a movable arm so that there is a possibility of adjusting the distance to the bush which is very helpful when maneuvering the machine in narrow rows. The operating unit includes a drum on which two types of cutting blades are mounted: vertical and horizontal ones, thanks to which shoots are cut and pre-shredded. The device is also equipped with a divider which is used to adjust the amount of undercut shoots to the intended by the operator. The operating unit is driven by a belt drive coupled to a hydraulic motor powered from the main hydraulic system of the tractor.
The machine is made in several versions that differ from each other with equipment:
- The undercutter hitched to the front of the tractor, left- and right-side,
- The undercutter hitched to the rear of the tractor, left- and right-side,
- The machine equipped with a hydraulically movable frame with an operating element.
