ABSTRACT:
A grass treatment apparatus is adapted to be coupled with a propellant vehicle in order to be movable over the ground and which mounts a plurality of grass treatment units which are engageable with the ground in order to carry out required grass treatment operations. The apparatus includes a main frame having mountings for coupling to the propelling vehicle and a grass treatment unit mounted on the main frame. A side frame is adjustably mounted on the main frame and has a grass treatment unit mounted thereon. The main frame has a mounting recess for receiving the side frame. A power operated device couples the side frame to the main frame and adjusts the side frame between an outwardly deployed position in which it is laterally spaced from the main frame and an inwardly deployed position in which the side frame is received by the mounting recess.
