摘要

Tractor unit pulling a three part mowing machine, in which the mowing units work in conjunction with each other and rotate around vertical shafts. The mowing machines are attached releasably to the first part of the tractor's connection points by means of a hydraulic lifting device. The lifting device is of the three point lift type, whilst the connection points form likewise a three point system rigidly connected to the tractor by means of an upwards directed coupling unit. This coupling unit supports at least one tractor P.T.O shaft at a distance from the lengthways symmetrical plane in the direction of forward movement. The coupling unit can be fitted to the front drive shaft of the tractor.
