Height Settings for Lawn Mowers
What is the best height my lawn mower should be set at if I am using it as a mulcher?
Mower height settings depend on the type of turfgrass and season. Use the higher range of mowing heights during the heat of summer. You can go with a lower setting in spring or fall.
Bluegrass, fine fescue and perennial ryegrass - 1 1/2 to 2 1/2 inches
Tall fescue - 2 1/2 to 3 inches
Bermudagrass - 1/2 to 2 inches
Buffalograss - 2 to 3 inches (or unmowed)
Bahiagrass, St. Augustinegrass - 2 to 4 inches
Zoysiagrass - 3/4 to 2 inches.
