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