Steps
Switch the mower off and pull out the battery and the safety key. Keep the battery indoors from now on so cold weather does not drain it.
Tip the mower on its side and block the blade with a piece of wood. Undo the blade bolt with a socket or wrench and lift the blade off.
Scrape and brush out the packed grass and dirt from under the deck. Wear gloves because the edges are sharp.
Wash the deck with soapy water and a cloth, then wipe it dry. Keep water away from the motor and wiring.
Spray WD-40 on the clean metal deck and blade bolt area to push out moisture and slow rust over winter.
Clamp the blade in a vise or hold it firmly and file the cutting edge at the original angle. Keep the blade balanced.
Refit the blade with the bolt and tighten it firmly with the wood block still holding the blade.
Store the mower in a dry shed or garage, standing upright and covered with a sheet or tarp to keep dust and damp off.
Keep the battery inside at room temperature, charged to about half, and top it up once a month over winter.
Tips and common mistakes
Never store a lithium battery fully flat or in a freezing shed, as it can fail to charge in spring.
File the blade along the existing bevel only, and replace it if it is bent or badly chipped.
Do not hose the mower down with a pressure washer, as water gets into the motor and bearings.
Questions
Do I need to drain fuel from a battery mower?
No. A battery mower has no fuel tank or engine oil, so skip those steps. Just remove the battery and clean the deck.
How often should I sharpen the blade?
Once a season is enough for most lawns. Sharpen it at winterizing time, or sooner if the grass looks torn rather than cut.
Can I leave the battery on the mower over winter?
It is better to take it off. Cold and long storage drain the cells, so keep it indoors at room temperature.
