Instructions: How to Start a Lawn Mower After Winter

Step 1:

Winterize your mower. Follow the instructions in your owner's manual to properly winterize your mower. Most small engine lawnmowers require the fuel tank to be drained and some fuel stabilizer added to prevent plugging and corrosion of the fuel system's internal components during storage periods.

Step 2:

Remove all backhoe contents from your mower. Most lawn mowers have a "pocket" in the back that catches the grass clippings as you mow. Make sure this bag is empty by removing it from the lawn mower and tapping it with a stick outside your garage or other storage area if necessary.

Stage 3:

Take the battery out of your mower. Most lawnmowers have a 12-volt lead-acid battery that powers the motor. If your mower has been stored in an area with no heat, move the battery to an area with warmer temperatures for at least two hours before attempting to start the mower.

Step 4:

Be sure to clean under the lawn mower regularly. Many people store their clippers on a piece of wood or brick for convenience. However, these materials can cause rust and dirt to build up under the mower deck. Be sure to remove all dirt and debris from under header before starting mower.

Step 5:

Check the condition of the air filter. If your lawn mower has been stored for a long time, the air filter will likely become dirty and dusty. To prevent dirt from getting into the mower carburetor and causing problems, remove the mower carburetor.Air filter and cleanor replace if necessary.

Step 6:

Check engine oil level. Your lawnmower engine should be completely drained before winter storage. However, if your engine has been idle for a long period of time and you haven't checked the oil level recently, check that the mower does not have too much or too little oil in the crankcase.

Step 7:

Check condition of spark plug. If the lawn mower is difficult to start the first time you try to start it, check the spark plug to make sure it is seated correctly. If your lawn mower has been stored for a long time, you can also replace this part.

Stage 8:

Make sure all screws holding the main components are tight. Lawnmower engine covers, carburetor covers and air filter covers use screws to hold them in place. Over time, these screws can come loose and cause significant problems if left unchecked. Make sure they are securely tightened before starting the mower.

Step 9:

Prepare a suitable area for cutting. To properly start the lawnmower after winter storage, you must select a flat, level area. Also, since the mower wheels cannot grip the grass while it is still wet, you want a dry grass surface without excessive dirt or large rocks. Finally, if possible, choose a day without wind to make it easier to start the mower.

Step 10:

Prepare new gasoline for your lawn mower. Before starting the mower, add fresh gasoline to the clean, dry gas tank. Do not use fuel that has been in the tank for an extended period of time, and never add fuel stabilizers or other additives to your lawn mower's gasoline.

Prepare a blade engagement bar. The motor turns the mower blade engagement bar to cut the grass. Attempting to start the mower without making sure this part is engaged could result in significant damage. Pull down on the lever on the side of the mower near the wheel so that it locks into place and the cord is free to hang.

Stage 12:

Prepare a suitable pull cord. Most lawn mowers require the pull cord to be in good condition and completely unobstructed. If possible, use a new piece of nylon cord with no sharp edges. Before pulling the handle to start the mower, make sure there are no other people or animals within 15 feet of the mower to avoid injury.
