bedknife

A bedknife is a crucial component in reel mowers, also known as cylinder mowers. It is a long, straight blade that is mounted in a fixed position at the bottom of the mower's cutting cylinder. This stationary blade works in conjunction with the rotating blades of the reel. As the reel spins, the grass blades are trapped between the reel blades and the bedknife. The shearing action created by the rotating reel blades against the fixed bedknife results in a clean, precise cut of the grass.

The sharpness and condition of the bedknife are paramount for effective mowing. A dull or damaged bedknife can lead to torn grass blades, resulting in a ragged appearance, increased susceptibility to disease, and potential browning of the lawn. Proper adjustment of the bedknife is also critical. It needs to be set at the correct distance from the reel blades to ensure an efficient cut without causing excessive wear on either component. Over time, bedknives wear down and require sharpening or replacement to maintain optimal cutting performance. Their design and material vary depending on the specific mower model and the intended application, from fine turf maintenance on golf courses to general lawn care.
