Benefits of Sharp Mower Blades: Research Update

Crabapple LandscapExperts know all about the value of keeping mower blades sharp! Dull mower blades:

 

● reduce the visual quality of turf because they shred the tips of the grass blades, producing a discolored cast
● increase disease susceptibility of the lawn, due to the creation of entry sites for pathogens at the tattered leaf tips
● cause growth to slow
● decrease water usage(!) Nebraska researchers Drs. Don Steinegger and Robert Shearman found that turf cut with a sharper blade actually used 33 percent more water than the turf mowed with a dull blade. They think this is due to the slower growth rate of the turf mowed with a dull blade. The researchers caution that using a dull blade isn’t the most pragmatic way to conserve water, noting that reduced visual quality, greater disease and slower growth more than offset the benefits of lower water use.
 ● most surprising, Steinegger and Shearman found that sharp mower blades cut fuel consumption by 22 percent. It makes sense that a dull blade would produce more resistance, but this study shows that the difference in fuel consumption is more than a theoretical consideration.
