A LOAD ADAPTIVE FLOTATION ARRANGEMENT FOR A MOWER

摘要

An arrangement for load-compensated balancing of an agricultural mowing machine consisting of a mowing unit (3) equipped with a knife unit (5) and a conditioner (7), supported by a spring suspension in a carrier frame (1), in which the mowing unit (3) is attached to the carrier frame (1) by at least two guide arms (9 and 10) and is supported by at least three spring elements (11, 12 and 13) acting between the mowing unit and the carrier frame, at least one of the spring elements (13) consisting of a hydraulic or a pneumatic cylinder or a bellows (14), whose lifting force compensates for the additional load to which the mowing unit is subjected when cutting a crop.
