FIELD: agricultural engineering.
SUBSTANCE: hinged apparatus has supporting poles, lifting levers, central upper tie-rod with shock absorber, angle braces and lower longitudinal tie-rods. Each angle brace is composed of regulated and movable stems. Regulated stem is mounted on lifting lever. Movable stem is positioned on lower tie-rod. Angle brace is provided with shock-absorber made in the form of hollow casing. Compression springs are located inside shock absorber casing. Upper and lower compression springs are mounted between regulated and movable stems. Movable stem is equipped with stop. Upper compression spring is positioned between hollow casing cover and stop. Lower compression spring is mounted between stop and lower cover of hollow casing. Diameter of stop is equal to diameter of hollow casing.
EFFECT: enhanced reliability in operation of agricultural machines hinged to tractor and reduced power and material consumption.
