Magnetic attachment of a bed knife in a reel mower assembly

摘要

A reel mower assembly comprises a mower reel rotatably mounted to a frame, and a drive operative to rotate the reel about a reel axis. Magnets are mounted on the frame and a bed knife (18) is magnetically held against the magnets in an operating position such that the bed knife is oriented in cutting relationship with the reel. Engagement means are operative to prevent sliding movement of the bed knife with respect to the magnets while allowing the bed knife to move away from the magnets when a separating force (FD) is exerted on the bed knife in a direction away from the magnets that is greater than an attractive force exerted on the bed knife by the magnets when the bed knife is in the operating position.
