Abstract
A modular unit for mounting on at least two different designs of self-propelled grass treatment machine, each machine having a number of mounting locations for mounting respective modular units and in which the mounting locations of one machine are different in type or design from the mounting locations on the other machine The modular unit contains a frame having end frame plates spaced apart from each other transversely with respect to the direction of forward travel of the machine; rotatable mountings provided on the end frame plates; a rotatable grass-treatment device having a drive shaft extending between the rotatable mountings, and provided with working elements arranged along its length; a device for applying drive to the shaft; and mounting points provided on the frame of the modular unit to accept at least two different types and/or arrangements of fitting brackets that permit the modular unit to be mounted on the grass treatment machines.
