FIELD: agricultural industry; mechanics.
SUBSTANCE: claw-like felling unit consists of a cutting mechanism and a fixed stop installed on a common base, a crimping lever with a drive hydraulic cylinder, which is hinged to the base, and a felling-jack mechanism. The latter consists of a lever jack. One end of the lever jack is made in the form of a jack, and the other end is hinged to the lower part of the base. The other end of the lever jack is connected to a sliding member. The latter by means of a lever mechanism is connected to the drive hydraulic cylinder. Lever mechanism consists of two levers which are hinged to each other at an angle. Lever mechanism with one of its ends is hinged to the drive hydraulic cylinder, and with the other end - to the base. Hinged joint of levers of lever mechanism is located in the sliding member.
