How to Tune Up Your John Deere Lawn Mower

How to Tune Up Your John Deere Lawn Mower

Excited to start up your John Deere lawn mower but want to make sure it’s in peak condition before taking on your yard? We’re here to get you started! Use our checklist below to tune up your John Deere Lawn Mower and make sure it performs exceptionally all season long.

1. Tune Up Your John Deere Lawn Mower: Drain Old Fuel and Change the Oil

Typically, fuel should be drained from your John Deere lawn mower before putting it into winter storage each year, but if there is any leftover fuel from last season left in the tank, make sure you drain it now. Because old fuel can separate into deposits and clog the carburetor, it is possible that you will discover some damage as you inspect your mower (if you find that any parts have been damaged, you can search for replacement parts here). Next, change the oil to help ensure engine longevity and better performance.

2. Tune Up Your John Deere Lawn Mower: Clean or Replace the Air Filter

Depending on what type of air filter you have, you can boost performance by cleaning or replacing the filter. Foam filters can be washed with hot water and dish soap, while paper filters should be replaced once they are no longer usable. To determine if your paper filter is in working condition, remove it from your mower, tap off excess dust, and hold it up to a bright light. If the light shines through the filter, it is clean enough to put back on your mower. If you cannot see any light, the filter is dirty and should be replaced.

3.  Tune Up Your John Deere Lawn Mower: Change the Spark Plug

Ideally, spark plugs should be replaced each year or after 100 hours of use, whichever comes first. Although spark plugs rarely go bad, they are good indicators of underlying engine problems and as a result should always be taken care of. Use a crescent wrench or pair of vise grips to turn the metal base and remove the spark plug, then place a few drops of oil into the open cylinder. Start the engine a few times to coat inside valves, then replace your old spark plug with a new one. Remember to use the same part number, as there are many types of spark plugs available as you work with different equipment (click here to find spark plugs).

4. Tune Up Your John Deere Lawn Mower: Sharpen Blades

Sharp blades can make a huge difference in cut quality. Check blades for excessive dents, chips, or wearing that could have an impact on mowing performance, and sharpen or replace depending on severity of damage.

5. Tune Up Your John Deere Lawn Mower: Double-Check Bolts, Wheels, Cables, and Belts

Finally, inspect your John Deere for any loose bolts, worn cables or belts, or damaged wheels. Tighten, repair, and replace as needed to help avoid future problems that could pop up later in the mowing season (click here to find parts by illustrated diagram).

Paying attention to these important tips can help you stay on top of your John Deere lawn mower maintenance and enhance the quality of your lawn all season. For questions about replacement parts, you can contact us here. Best of luck, and let the mowing begin!

How to Level a John Deere Riding Lawn Mower Deck

How to Level a John Deere Riding Lawn Mower Deck

When mowing around your home and businesses, pay attention to the recently mowed lawn. If you notice ridges forming where you recently mowed, the deck on your lawn mower may not be leveled. Luckily, leveling your mower deck is not a time consuming task, allowing you to get back to cutting the grass in no time.

Before performing any maintenance on your riding lawn mower, refer to your owner’s manual for maintenance and safety information. Maintenance instructions vary by model. Depending on your riding lawn mower model, our instructions may vary slightly so refer to your owner’s manual for more specific instructions.

Before you begin leveling your lawn mower deck follow these safety instructions. Park your mower on a hard, flat surface and shut the engine off. Set the parking brake to prevent your machine from rolling back, injuring you or others. Remove the ignition key to prevent accidental starting and wear heavy leather gloves since you’re working near mower blades.

Tools you’ll need:

  • Exact Adjust wrench
  • 18 mm wrench
  • Tire pressure gauge
  • Mower gauge

Here’s what to do:

Before starting, make sure the tires on your John Deere mower are inflated. Check your owner’s manual for information on tire pressure numbers.

John Deere Tractors

Raise the mower and place the mower cutting height knob at the position specified for deck leveling. Lower the mower and check that the mower wheels are not making contact with the ground and raise if necessary. Place the mower gauge under the mower at the adjustment point near the left rear corner. If your tractor does not make contact with the gauge, adjust the deck accordingly.

Check the mower front to back level at the front adjustment point on the front left deck hanger bracket. If necessary, use the 18 mm wrench to loosen the rear nuts on each of the front lift rods. Turn the nuts on each side until the gauge slips under the front adjustment point.

Fully raise the tractor and adjust the height control knob to the desired height, then lower the machine. Adjust the wheels so they’re at least 1/4 inch off the ground. The wheels will carry the mower deck over higher areas in the lawn to give it an even cut.

John Deere Zero Turns

Make sure the mower is parked and then mount the mower. Raise the deck into the transport position. Make sure the anti-scalp wheels are not making contact with the ground.

Lower the deck to 76 mm (3 inches). Position the right mower blade on the discharge side in the front to rear position. Once the blades are in the correct position, measure the distance between the front blade tip to the ground. Use the mower gauge to check the mower blade level. The front blade tip should be 76 mm, with a tolerance of +/- 2 mm.

Move to the other side of your zero turn and position the mower blade in the front to rear position. Measure the blade’s tip to make sure it is 76 mm as well.

If one side is lower than the other, loosen the jam nut on the adjustment rod and turn the rod tube as needed to bring the tip into the proper position. When satisfied, lock the jam nut to secure the setting. Re-check both sides of the deck after the adjustment has been made to ensure it is within specification.

How to Change the Deck Belt on a John Deere Riding Lawn Mower

How to Change the Deck Belt on a John Deere Riding Lawn Mower

When the deck belt on your John Deere riding lawn mower begins to make noise, slip, or snap, it’s time to replace it. It’s a good idea to stay on top of maintenance and repairs to extend the life of your mower. Though changing the deck belt on your lawn mower may seem overwhelming, it’s a relatively easy task. Here’s how to change the deck belt on a John Deere riding lawn mower.

Before performing any maintenance on your John Deere lawn mower, refer to your operator’s manual for maintenance, safety information, and instructions for your machine. Maintenance instructions vary by model, so depending on your riding lawn mower model our instructions may vary slightly.

Before changing the deck belt, make sure your lawn mower is parked on a flat, level surface. Shut off the engine, remove the key from the ignition, and disconnect the spark plug wire to prevent accidental starting.

Once this is done, raise the deck height lever to the highest setting. Place wooden blocks under each side of the mower deck to prepare for deck removal. Lower the deck height lever to its lowest position so the mower deck rests on the blocks.

Disconnect the deck lift linkages by removing the pins and washers. Remove the linkages from the deck, disconnect the rear draft arm, and disconnect the mower deck belt to remove the deck from the mower. Remove the wooden blocks and allow the deck wheels to touch the ground. Slide the deck from underneath the mower.

Remove the belt covers by removing the screws that hold it in place. Loosen the sheaves and remove the old deck belt. Replace it with a new John Deere deck belt.

Route the deck belt around the sheaves and pulleys, following the same path as the belt you removed. Replace the belt covers and screw them into place, and re-tighten the sheaves with the belt in position.

Place the deck height lever in the transport position to reattach the mower deck. Slide the deck back under the machine. Reinstall the pins and washers to reattach the linkage to the deck, and reattach the rear draft arm to the deck.

Lastly, reconnect the spark plug ignition wire and start the mower.

How to Install a Mulch Kit on a John Deere Tractor

How to Install a Mulch Kit on a John Deere Tractor

Mulch kits can give your John Deere tractor more value when mowing. Mulch kits generally include mulching blades and a mulching plug, along with necessary hardware for installation. The mulch blades chop grass clippings into smaller pieces than the standard blades, and those smaller pieces decompose faster and help return nutrients back into the soil, keeping your grass healthy. Continue reading to learn how to install a mulch kit on your John Deere tractor.

Before performing any maintenance on your John Deere tractor, refer to your owner’s manual for maintenance and safety information. Maintenance instructions vary by model. Depending on your model number, these instructions may vary.  Be sure to refer to your owner’s manual for detailed instructions.

To install a mulch kit on a John Deere tractor, begin by removing the mower blades. Use a Jungle Jack or other form of jack to lift the front of your mower to create space under the mower deck. Raise the deck to the highest setting. Remove the center holding nut from the mower blade with a wrench. Use a gloved hand to keep the blade from turning while removing the nut. Save the nut for installing the mulching blade. Repeat this blade removal step for the mower blade on the other side of the deck.

Now that the old blades have been removed, it’s time to replace them with the new blades included in the mulch kit. Place the center hole of the mulching blade over the mounting stud on the underside of the mower deck. Make sure the cutting end of the blade faces forward when spinning in a clockwise direction. Use your gloved hand to hold the blade in place while tightening the holding nut with your wrench. Repeat this step to install the mulching blade on the other side of the deck as well.

To install the mulch plug on your John Deere tractor, lift the discharge chute up. Place the mulch plug into the deck discharge chute opening with the carriage bolt threads facing upward.  Fit the mulch plug onto the mower deck lip and remove the tape from the metal deflector and discharge chute so that it falls into place. Insert the carriage bolt into the mounting hole on the lower left side of the mower deck. Tighten the locking wing nut.

You are now ready to use your John Deere tractor as a mulcher. In the future, if you want to mow without mulching, remove the mulch plug, and you will not need to change the blades.

How to Use John Deere Maintenance Kits

How to Use John Deere Maintenance Kits

Staying on top of maintenance is essential to maximizing the performance and life of your outdoor power equipment. John Deere makes it easy to tune-up your tractor all on your own. They also make it easy to match a kit to your specific tractor model by listing the model on the box so you’ll never have to worry about missing parts necessary for maintenance.

Most John Deere Maintenance Kits include:

2 quarts oil

1 oil filter

1 air filter

1 fuel filter

Air precleaner

Spark plugs(s)

Additional tools (not included in Maintenance Kits):

Oil filter wrench

Drain pan

Towels/rags

Pliers

Socket wrench

Spark plug gap gauge

 

Here’s how to perform maintenance on your John Deere tractor using a John Deere Maintenance Kit.

Change the oil and oil filter

Drain the old oil by running your tractor’s engine for a couple minutes so that the oil flows better. Set your drain pan on the ground to catch the old oil. Remove the drain cap and allow the oil to drain completely. Once the oil has been drained, remove the dipstick and use a towel/rag to wipe off old oil.

Before replacing the oil filter, use your towel or rag to clean the area around the filter and then place the drain pan under the filter tray. Remove the old filter and gasket and make sure to dispose of it properly. Rub a light coat of fresh oil on the new filter gasket and screw on the new filter by hand, until the rubber gasket makes contact with the filter base. Then tighten the filter another half turn to make sure it’s secure.

Next, install the drain cap and pour in the new oil, but make sure not to fill it past the full mark. Run the engine again to make sure you don’t have any leaks, and ensure proper fill by checking the dipstick.

Change the air filter

Before replacing the air filter, make sure the engine is cool. You should also brush away any debris covering the air intake screen. Take off the air filter cover then remove the air filter and the precleaner. If your maintenance kit comes with a replacement precleaner, use the new one (to make sure, check your operator’s manual). Put in the new air filter and reinstall the cover.

Change the fuel filter

First, make sure you are in a well-ventilated area and that the engine on your tractor is cool. Check the fuel lines to see if they look worn or cracked. If so, have them replaced. Look at the arrow on the old fuel filter – it shows the gas flow. Make sure the arrow on the new filter goes the same direction as the arrow on the old filter.

Use your pliers to move the clamps away from the filter. Pull off the hoses, gas tank side first, and quickly attach the hoses to the new filter, gas tank side first. Use the pliers again to put the hose clamps back in their original place. Run the engine for a couple minutes and check for leaks.

Change the spark plugs

Pull off the plug wires and use the wrench to loosen the plugs. Remove the plugs and use the spark plug gauge to set the right gap (your operator’s manual will show you the proper gap size). Install the new spark plugs finger tight and then use the wrench to fully tighten the spark plugs. Lastly, reinstall the plug wires.

Sharpen/Replace Blades

Blades are not included in John Deere Maintenance Kits but whenever you perform regular maintenance you should sharpen your blades or replace them if they’re worn. You can sharpen your blades on your own or bring them to a professional.

John Deere Maintenance Kits will keep your equipment running like new year after year. They come with everything you need to service you lawn equipment so stay on top of maintenance to see the best results with your equipment and your lawn.
