Storage

Clean the Flail Mower at the end of the working season or when the mower will not be used for a long period.

1.Clean off any dirt or grease that may have accumulated on the mower and moving parts. Scrape off compacted dirt from under the hood and then wash the surface thoroughly with a garden hose. A coating of oil may also be applied to the area to minimize oxidation.

2.Check rotor knives and knife bolts for wear and replace if necessary. See “Rotor Knife Replacement” on page 16.

3.Inspect for loose, damaged or worn parts and adjust or replace as needed.

4.Lubricate as noted in the Lubrication portion of this section starting on page 18.
