Regular mower maintenance is essential to achieve the best possible quality of cut. Dull mowers tear leaf tissue, severely wounding the plant and resulting in formation of frayed and necrotic leaf tips. Severe wounding may limit growth and development of grasses and increase susceptibility to stresses such as drought, pathogens, insects, and traffic. The objective of this study was to quantify mower sharpness and mowing injury over time. This information will be used to develop general mower maintenance guidelines and to determine how frequently reel-type mowers should be sharpened to achieve the best possible quality of cut.
