In a leaf loading method, material is picked up from the ground by operating a rotary beater and a rotary broom. Material is then delivered between the beater and the broom by rotating the beater and the broom in opposite directions. Next material is guided from between the beater and the broom toward an auger disposed rearwardly of the broom. Finally material is transferred from the auger into a thrower by rotating the auger and then material is discharged by operating the thrower.
