Abstract: A powered mobile unit for turf-care apparatus comprises a chassis, driven and steerable front wheels, rear wheels supporting the chassis, a seat carried at least mainly by the rear wheels, a linkage behind the rear wheels for the attachment of turf-treating implements; and a powered hydraulic unit capable of activating the linkage to lift an attached implement clear of the ground and of applying such downward pressure to the implement as to cause the rear wheels to be raised clear of the ground with an operator in the seat, while the unit is mobile.
