Mower Deck Cleanout and Seasonal Inspection Before Storage

The end of the mowing season is when a little preparation saves repair work next spring. A deck put away dirty and wet develops rust and seized joints. A cleanout and short inspection now means the mower starts ready next season.

Wash and scrape the deck clean

Remove every trace of grass from under the deck, around the spindles and inside the housing. Caked grass holds moisture and promotes rust. Hose the underside and let it dry fully. A clean deck also makes the inspection easier.

Inspect blades, belts and spindles

With the deck clean, check the blades for sharpening or replacement, inspect the belt for cracking, and spin each spindle for roughness. Note what needs ordering over the winter. A worn part identified now is replaced before the season, not on the first busy day.

Grease every fitting

Grease all spindles, castors and pivot points before storage. A fresh film of grease protects the bearings over the idle months. Wipe off excess grease so it does not collect dust. Greased joints sit ready rather than seized.

Touch up paint and protect metal

Touch up chipped paint on the deck shell, and coat bare spots. A light oil on exposed metal prevents rust over winter. Store the mower under cover, off the damp floor. A sheltered, clean deck does not develop the rust that a wet one does.

Make a list for spring

Note the parts that need ordering: blades, belts, bearings. Put the list with the mower. Next season starts with the parts on order, rather than discovering them in the field. A clean, inspected, greased deck comes back into service without surprises.
