Abstract
A tractor-drawn implement for breaking up caked litter on the floor of a poultry house includes a stationary blade which passes beneath the surface of the litter and a rotary rake whose tines are flattened and are inclined at an oblique angle to radial planes of the rake. The tines break up caked litter as they turn; their inclination causes sweeps the litter particles toward one end of the blade, away from the wall of the house.
