What problems can occur from storing a lawn mower in a shed?

Storing a lawn mower improperly in a shed can lead to some problems over time. Here are some of the most common issues that can occur:

Rust and corrosion – Dampness promotes rust on steel parts if the mower is not kept clean and dry.

Gas degradation – Old gasoline left in the mower eventually oxidizes and turns to varnish, clogging the carburetor.
Rodent damage – Mice and other rodents are attracted to the smelly gas and oil in stored mowers.
Tire flat spots – The weight of the mower can flatten tires over time on concrete floors.

Battery drain – Batteries self-discharge over time and may die if left connected.
Gummed up carburetor – Varnished gas and oxidized oil thickens over time, clogging the carb.
Faded paint and plastic – Sunlight coming through windows may fade exposed surfaces.

Proper preparations like stabilizing fuel, putting the mower up on blocks, disconnecting the battery, and covering machine or windows can help minimize these potential issues. Periodic inspection and maintenance is also recommended for long term shed storage. With some care, major problems can usually be avoided.

Should you cover a lawn mower in a shed?

It is generally recommended to cover a lawn mower when storing it in a shed to help protect it from dust, dirt, moisture and potential rodent damage. Here are some benefits to covering your mower:

Protects surfaces from dust buildup – A cover keeps dust off, helping maintain the mower’s appearance.

Reduces moisture accumulation – A cover forms a moisture barrier to keep condensation off the machine.
Deters nesting rodents – Rodents are less likely to nest on a covered mower.
Hides the mower – A covered mower is less attractive for thieves if shed doors are left open.

Prevents accidental bumps – A cover protects from dings, scratches and dents during storage.
Keeps mower cooler – A cover blocks sunlight to prevent internal heating in hot weather.
Maintains value – A covered mower usually retains higher resale value from reduced wear.

The main drawbacks are the cost of a cover, and the need to take it on and off whenever using the mower. But for long term shed storage, a quality mower cover is highly recommended to maintain the condition and appearance of your investment. Make sure the cover fits snugly and allows adequate ventilation.

Is it necessary to disconnect the battery when storing a lawn mower?

For mowers with electric start engines, it is generally recommended to disconnect the battery when storing the mower for extended periods of time, usually longer than a month. Here are reasons why:

Prevents slow drain – Batteries self-discharge over time, and may die after months.

Avoids recharging – Recharging degraded batteries can damage them further.
Reduces corrosion – Disconnecting terminals eliminates electrical paths for corrosion.
Saves having to recharge – A dead battery means needing a recharge before using.

Extends battery life – Deep discharges from self-drainage shortens overall battery life.
Lower fire risk – Draining batteries are more susceptible to short circuits and sparks.
Quick and easy – Only takes a minute to disconnect battery cables.

However, if storing for just 1-2 months, the battery may be fine left connected if it was fully charged beforehand. But for any longer storage, playing it safe and disconnecting terminals can save hassle and expense later. Just be sure to reconnect properly when taking the mower back out of storage.

What fuel stabilizer is best for lawn mowers in storage?

When storing gasoline-powered lawn mowers over the off season, it’s highly recommended to add fuel stabilizer to the gas tank to maintain fuel quality and prevent issues like varnishing of fuel systems. These 3 stabilizers are top rated:

Brand	Benefits
Sta-Bil 360 Marine	– Prevents ethanol fuel separation – Protects against corrosion – Formulated for all engines
STA-BIL 22275 Storage	– Stabilizes fuel up to 2 years – Prevents gum, varnish buildup – Performs well in all temperatures
Lucas Fuel Treatment 10013	– Cleaner and stabilizer 2 in 1 – Reduces need for octane by up to 2 levels – Improves fuel economy

The marine formulas are ideal for steamy shed conditions. STA-BIL is proven over decades. Lucas has a dual-purpose cleaner-stabilizer. Follow dosage directions on the container and run mower briefly to circulate. Properly stabilized gas remains fresh and stable for smooth starting and operation when taking the mower back out of storage.

Should you change oil before storing lawn mower?

It is recommended to change the engine oil and filter before storing most gas-powered lawn mowers for an extended period of 3-6 months or longer. Here are reasons why:

Removes old contaminated oil – Preventing varnish and acid buildup in the engine.
Installs fresh oil – Coats components with new protective film for storage.

Replaces old filter – Allows extended storage with minimal circulation.
Checks for metal pieces – Evidence of wear indicates needed repair.
Follows manufacturer advice – Some specify fresh oil for storage.

Enables easier starting – Oil has not thickened or separated when restarting mower.
Improves storage area cleanliness – Avoids leaks of old oil.

The oil change before storage results in easier starting, reduced wear at restart, and extended engine life. It’s quick insurance when storing the mower over frigid or sweltering temps. Let the engine warm then drain old oil completely before refilling to proper level with fresh oil of the manufacturer’s recommended weight and detergent levels.

What is the best way to store gasoline for lawn mowers over the winter?

Here are some tips for properly storing lawn mower gasoline over the winter:

Add fuel stabilizer to gas – Prevents oxidation and varnishing of fuel.
Fill tank or container 95% full – Leave room for expansion from temperature changes.

Seal containers completely – Prevents moisture absorption and evaporation.
Store in cool, dark location – Sunlight and heat speed up fuel degradation.
