The Last Cut Counts Twice: Putting Your Mower Away Properly This November

November has a way of making the mower look redundant. The grass has slowed, the light is flat, and the shed is already full of half-finished jobs. But the way you park the mower now has a lot to do with how easily it fires up next spring. A focused 45 minutes before the frosts settle in is usually cheaper and calmer than a first cut that turns into a repair mission.

This isn't about a full workshop service. It's about the handful of checks that matter when a machine is going to sit idle for weeks in a damp British shed.

Decide when the mower actually stops

In most UK gardens, grass growth tails off through late autumn as soil temperatures drop and daylight shortens. You're not chasing a neat stripe any more; you're tidying up. The last cut of the season should usually be a little higher than your summer setting, and it should only happen when the grass is dry and frost-free. Cutting wet or frozen grass is hard on the machine and rough on the lawn.

Once growth has clearly stalled and the forecast is more cold than mild, stop cutting and start storing. If you get a surprisingly soft spell later on, a light high cut is fine, but don't keep going just because the mower is still out. The aim is to send it into winter clean, dry and protected, not caked in the last clippings of the year.

Petrol mowers: deal with the fuel before it deals with you

Stale petrol is one of the most common reasons a mower won't start in spring. Modern UK petrol often contains ethanol, which can attract moisture and degrade in a machine that's left sitting. A half-full tank over winter is not doing you any favours.

You've got two sensible options. Either run the tank dry by letting the engine run until it stops, or fill it with fresh fuel and add a fuel stabiliser according to the product instructions. If you're running it dry, do it outside and let the engine cool before you start cleaning. If you're storing it full, make sure it really is full, not half-hearted, to reduce condensation space in the tank.

While the engine is still slightly warm, check the oil if your model has a dipstick or oil filler. If it's due a change, do it now rather than in a rush next spring. Tap out the air filter, check the spark plug, and note anything that looks tired. A quick phone photo of the spark plug gap or the blade bolt arrangement can save head-scratching later.

Cordless mowers: get the battery out of the shed

Battery-powered mowers are simpler in some ways, but they have their own winter weakness: cold, damp storage. Lithium-ion batteries don't like frost, and they don't like being left on the charger for months either.

Remove the battery, wipe it clean, and store it indoors somewhere frost-free and dry. Aim for a partial charge rather than full or empty, and check the manual for your specific model. Clean the contacts gently with a dry cloth, and give the battery housing a quick brush out so no grass debris sits against the terminals. Don't put the battery back in the mower until spring.

Clean the deck and look at the blade

Grass clippings hold moisture against metal. Over winter, that's a recipe for rust and a stiff, unhappy mower. Disconnect the spark plug lead on a petrol model, or remove the battery on a cordless one, then tip the mower safely according to the manual.

Use a plastic scraper or an old stiff brush to clear the underside of the deck. Avoid jabbing at it with a screwdriver; you don't want to scratch through paint or damage a belt. Check the blade while you're there. A blunt blade tears grass rather than cutting it cleanly, and a badly unbalanced one can stress the motor or engine. If the blade is nicked, bent or past its best, sharpen or replace it now. Wear gloves and eye protection, and use the correct spanner or socket. If you're not confident, book it in with a local service centre rather than improvising.

Keep damp away from the machine

A British shed can be a surprisingly hostile place. Condensation forms on cold metal, dust sheets trap moisture, and concrete floors pull damp upwards. Once the mower is clean and dry, park it on a pallet, a shelf or a couple of offcuts of timber rather than straight on the floor. A breathable cover is fine; a tightly wrapped tarpaulin is not, because it can trap moisture underneath.

Pick a dry day to air the shed, check for leaks, and move anything corrosive, such as fertiliser or salt, away from the mower. A quick look for rodent nests and chewed cables is also worth doing now rather than discovering in March.

The short kit list

• Plastic scraper or old stiff brush
• Gloves and safety glasses
• Correct socket or spanner for the blade
• Fuel stabiliser, if you're storing petrol
• Dry cloth for battery contacts
• Breathable cover or old towel
• Pallet or timber offcut for floor clearance
• Notepad or phone for photos and part numbers

Park it properly, thank yourself later

None of this is glamorous. But a clean deck, a checked blade, sensible fuel or battery storage and a dry parking spot are the difference between a mower that starts on the first pull and one that sulks through the first warm weekend of spring. Give it 45 minutes this November, then shut the shed door knowing the job is done.
