Landfill compactor vehicles

A landfill compactor vehicle comprising two front ground-engaging steel wheels, two rear ground-engaging steel wheels, each of said wheels having a cylindrical rim, compactor teeth of cast construction welded to and extending radially outwardly of the rim of each ground-engaging steel wheel, and each cast compactor tooth comprising at least one slicing portion integral with a tamping portion, said slicing portion extending radially outwards of the tamping portion, said slicing portion being generally of rectangular plate-like configuration with a wheel rim-remote peak, said tamping portion being of substantially pyramidal configuration extending from a face of said slicing portion, said compactor teeth of each wheel being arranged around the rim thereof in a twin helical pattern with slicing portions thereof lying at an acute angle to the direction of rotation of the wheel, the wheels being fitted onto the landfill compactor vehicle with the slicing portions of the compactor teeth of the two front wheels leading the tamping portions thereof, in terms of the direction of wheel rotation, the tamping portions of the two rear wheels lead the slicing portions thereof, in terms of the direction of wheel rotation, and the slicing portions of the teeth of one front wheel and its opposite rear wheel lying in the same or parallel planes while the slicing portions of the teeth of the other front wheel and its opposite rear wheel lie in the same or parallel planes normal to the first-mentioned planes;

• whereby, the front wheel teeth have an inboard "screwing" action on the refuse or waste, while the rear wheel teeth have an outboard "screwing" action, or vice versa, depending upon the direction of vehicle travel.
