Service - Cutting Units


IMPORTANT: Avoid damage! Backlap cutting reel routinely to prolong life of reel. Do not overtighten bed knife or excessive wear at the ends will occur.

To maintain sharp edges required on cutting reel, follow this procedure:

1. Before backlapping, adjust bed knife to cutting reel (See Adjusting Bed Knife To Reel in this section). The bed knife must be adjusted to assure a light, even contact over the entire length of the blade.
