A modification of rotary mowers is mulching mowers. These are designed to cut leaf blades into very small pieces that are able to fall into the lawn rather than remain on top of the grass. As these pieces are small, they decompose more quickly than blades cut to traditional size. The mower blades are designed to create a mild vacuum in the mower deck until the leaf blades are cut into these small pieces. Mulching mowers do not have the traditional discharge chute as do most rotary mowers.
Reel mowers are for highly maintained turf where appearance is important.
Reel mowers cut with a scissor-like action to produce a very clean, even cut. They are used at cutting heights of 2 inches or less. Bermuda and zoysiagrass are best cut with a reel mower. The number of blades needed to produce a smooth uniform cut will depend on the mowing height. Generally, as the height is lowered, the greater the number of blades is required on the reel.
