Abstract
Energy for mowing turfgrass was measured with an electric-motor-powered rotary mower and microprocessor-controlled electric power demand analyzer. Mowing energy increased with increased fertilization, decreased mowing height, and increased moisture on the turfgrass, and varied with genotype. A gasoline-powered mower required more direct and total primary energy for mowing turfgrass than an electric mower.
In this experiment, a gasoline-powered rotary mower used considerably more energy than an electric mower. | ||||
