Mowing energy and fertilizationFluck, R. C. and P. Busey.  1988.  Energy for mowing turfgrass.  Trans. ASAE 31:1304-1308.


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.
