摘要： A forklift vehicle having front wheels mounted on retractible horizontally extending legs which are normally locked in position, by cylinder operated locking pins, to slide plates on the rear frame of the vehicle. To collapse the vehicle, the fork carriage is rolled forwardly on the front legs; locking pins are hydraulically extended from the fork carriage into the legs while the rear locking pins are hydraulically retracted, and then the mast carriage is retracted retracting the front legs with it. The procedure is reversed to extend the front legs. An operator protective cage and seat extends rearwardly of the rear vehicle frame and can be collapsed upwardly and forwardly, further shortening the vehicle length.

摘要： An apparatus for spraying a treatment liquid onto grass growing on a ground surface includes a plurality of rotatable discs spaced laterally apart across the path of travel. Each disc has a plurality of cutters which are adapted to penetrate the ground surface and to cut holes therein as the apparatus travels forwardly. The holes are spaced apart along the path of travel and are also spaced apart laterally. The apparatus also includes a set of nozzles positioned on the apparatus above the grass such that each nozzle is spaced rearwardly along the path of travel from its associated disc but is aligned along the path of travel with such disc. The nozzles are adapted to spray the treatment liquid. The apparatus also including a controller for causing the nozzles to spray the treatment liquid into the holes.
