2066678 9201613 PCTABS00010 A refuse packer includes a paddle (14) which oscillates horizontally about axis (19) through about 200· to sweep refuse into a storage chamber of a vehicle (not shown). The paddle has an actuating assembly (26) supported by a single housing (27) secured to a vehicle chassis. The actuating assembly has a drive shaft with a hexagonal end clamped in a hexagonal opening (21) of the paddle. The drive shaft also has a pinion engaged by a pair of opposed toothed racks each end of each which slides in hydraulic cylinders (35, 36, 37, 38) which act to oscillate the shaft and paddle. A pair of hydraulic resistance cylinders (40 is shown) oppose side loads set up by the engagement of the racks with the pinion. In former arrangements the paddle was coupled to a crank plate moved by hydraulic rams which swung as they reciprocated. This led to uneven torque on the paddle and a tendency to stall midstroke, whereas the present drive provides even torque, throughout the oscillations.
