Storing Your Lawn Tractor for Winter

 

file

After you cut the lawn for the final time for the season, it's time to prepare your lawn tractor for its winter hibernation. Taking the right steps to store your tractor in the fall saves you time and trouble when it's time to crank up the riding mower in the spring.

These general guidelines help you prolong the life of your tractor and prepare it for smooth operation when you pull it out next season.

What You Need

  • Engine tune-up kit containing oil, spark plugs, air filter, fuel stabilizer and fuel filter
  • Lubricants such as multi-purpose grease and mower deck spray
  • Replacement belts and cutting blades, if needed
  • Cleaning brushes, scraper, soapy water and rags

Wash Under the Deck

Cleaning the mower deck now prevents rust from creeping in during the off-season.

If your lawn tractor’s deck doesn't have a deck washout port, park the tractor near a faucet and stop the engine. Use a hose with a spray attachment to clean under the deck.

Tip: You can install a washout port on your mower deck using this universal add-on kit if your deck doesn't have one.

If your mower deck has a washout port, follow these steps to clean the underside of the deck.

 

1. Park the lawn tractor in a clear and level area of lawn, near an outside water faucet with the deck's discharge chute pointed away from people, pets, the house and parked vehicles Set the parking brake and stop the engine.

 

2. Remove the bagger chute or mulch cover so water and debris can fly out the discharge chute during cleaning.

 

3. Connect a water hose from the faucet to the washout port on your mower deck and turn on the water.

 

4. Start the engine and move the throttle to the fastest setting. Engage the cutting blades. Leave the blades running for several minutes to thoroughly clean under the deck.

 

5. Shut off the cutting blades and stop the engine.

 

6. Turn off the water and disconnect the water hose from the washout port.

 

7. Start the tractor and move it to a dry area on concrete or asphalt. Engage the cutting blades for several minutes to help dry the underside of the deck.

Prepare the Deck for Storage

For the next phase of cleaning, park the tractor near its storage area and let the engine to cool.

 

Many owners' manuals recommend that you remove the mower deck and store it disconnected from the tractor for the winter. Refer to your owner's manual for specific instructions on how to store your deck. Here are common steps to take when getting the mower deck ready for storage.

 

  1. Disconnect the deck fasteners and pull the mower deck from under the tractor.

  2. Thoroughly clean the underside of the deck. Scrape off any remaining grass clipping or debris and wipe the underside of the deck with rags. Replace any damaged or dull mower blades now so you get a clean cut when you use the mower in the spring.

  3. To help prevent grass from sticking to the underside of the deck, spray the underside with a coat of Mo-Deck spray.

  4. Remove the mandrel pulley covers and clean grass and debris off the mandrel pulleys. If you see grease fittings on each of the mandrel pulley housings, add grease to fill each mandrel using a grease gun. Stop filling when you encounter the resistance—that means the mandrels are full. Wipe off residual grease after filling each mandrel. Examine the deck belt and replace it if necessary.

  5. Wash the top of the mower deck and the mandrel pulley covers with a rag dipped in soapy water. Wipe the deck with a clean rag soaked in clear water and let it dry.

  6. Touch up any nicks or scratches on the deck by lightly sanding the area and applying touch-up paint.

  7. Reinstall the mandrel pulley covers after the deck dries completely. 

 

Your mower deck is now ready for storage. Move it to your storage area if you're keeping it detached from the tractor.

Prepare the Engine

Prepping the engine now saves time next spring when the grass takes off.

 

Fuel and oil. You have two options for preventing gummy deposits from forming in the carburetor and fuel system over the winter:

 

Run the engine until it burns all the gasoline in the tank and fuel system. The engine dies when the fuel runs completely dry.

 

Add fuel stabilizer and run the engine for 10 minutes so the fuel with stabilizer enters the carburetor. Change the engine oil so the lawn tractor has fresh oil when you start the it in spring.

 

Lube the pistons and change the plugs. Remove the spark plugs) and pour one ounce of oil into each spark plug hole. Distribute the oil through the cylinder by turning on the engine for 5 seconds. The oil coats the piston and cylinder to prevent corrosion during storage.

 

Gap and install new spark plugs.

 

Replace or clean the filters. If your tractor engine has a fuel filter, follow the directions in your owner's manual to replace it. Remember to clamp the fuel lines to prevent gas from spilling if you didn't run the engine dry of fuel earlier.

 

Remove the air filter cover and carefully pull off the pre-filter and paper air filter. Wipe the air filter base with a damp cloth, taking care to prevent dirt from entering the carburetor intake port on the air filter base.

 

Replace the pre-filter if you find holes or damage. If the pre-filter is in good shape, wash the pre-filter in soapy water and then rinse it with plain water. Pat the pre-filter dry with paper towels.

 

Tap the paper air filter on the ground to remove dust and dirt. Replace the paper air filter if it's too dirty to clean or damaged. Reinstall the air filter and pre-filter on the engine.

Clean the Battery

Disconnect the black battery cable and then the red one. Pull the battery out of the tractor and wipe it with a clean wet rag. Dry the battery thoroughly.

 

Clean deposits off both battery terminals and both battery cable ends by brushing them with a wire brush until the metal turns bright. Coat the battery terminals with grease or petroleum jelly to prevent corrosion during storage.

 

Place the battery back in the tractor but don't reconnect the battery cables. Connecting the battery during storage causes corrosion and battery power leakage. Position the battery cables so they don't contact the battery terminals.

 

If you have a battery charger, fully charge the battery now. Even after following these steps, the battery may still require charging in the spring before you start the tractor the first time.

Prepare the Tractor

Blow grass clippings and debris off the tractor body using a leaf blower or a compressed air hose. Wipe the body with a damp cloth. Repair scratches and nicks by sanding them lightly with fine grit sandpaper then apply a coat of touch up paint.

 

Clean debris from under the tractor, especially the steering plate below the brake pedal. Debris often collects on top of the steering plate and can restrict brake pedal movement.

 

Check the ground drive belt and replace it now if it's worn or damaged. Your owner's manual shows how to route the ground belt over the pulleys and through the belt keepers.

 

Now is a good time to check the air pressure in the tires and fill them with air if needed. Replace any damaged or tread-bare tires.

Store the Tractor

Push the tractor to your storage area, preferably a dry spot indoors. Don't store it indoors with gasoline in the tank if gas fumes may reach an open flame or spark.

 

If you store the tractor and mower deck outside, move the mower deck under the tractor and cover them with a protective lawn tractor cover that doesn't retain moisture. Don't use a plastic cover because it doesn't breath, allowing moisture to condense on tractor surfaces, which causes rust.

 

It might seem like putting away your lawn tractor is a lot of work, but you’ll be glad you did it in the spring, when yard care goes from 0 to 60 overnight. If this to-do list is just too much, you can put off changing the oil and replacing the spark plugs until spring—but that will cut into the time you have for picking out impatiens at the garden center.
