How to Change the Spark Plug on Your Cub Cadet Lawn Tractor

How to Change the Spark Plug on Your Cub Cadet Lawn Tractor

The spark plug on your Cub Cadet equipment should be replaced at least once a year of after 100 hours of use. Spark plugs provide an ignition source for your machine’s engine to power your Cub Cadet lawn tractor. When they go bad, mowing your lawn becomes a challenge. Change the spark plug on your Cub Cadet lawn tractor regularly to keep your mower up and running throughout the whole season.

Before performing any maintenance on your Cub Cadet lawn tractor, refer to your owner’s manual for maintenance instructions and safety information. Maintenance instructions vary by model, so depending on your lawn mower model our instructions may vary slightly.

Before working on your Cub Cadet mower, follow these safety precautions:

  • Shut off the engine
  • Allow the engine to become cool to the touch
  • Disconnect the spark plug wire to prevent accidental starting
  • To carry out this task, you’ll need these tools:
  • 5/8 deep well socket
  • Wrench
  • Extension

To change the spark plug on your Cub Cadet lawn tractor:

  • Locate the spark plug on the side of the engine.
  • Use your socket to loosen the spark plug. Loosen it and grab the spark plug on the end, and give it a couple more turns.
  • Install the new spark plug.
  • Replace the old spark plug with a manufacturer approved replacement part (refer to your Cub Cadet owner’s manual).
  • Hold the spark plug on the end and stick it into the proper hole on the tractor.
  • Turn the spark plug to the left to make sure that it is starting to thread in properly, but turn it to the right to tighten it.
  • Tighten the spark plug by hand. By doing this, you can tell if the threads are going in correctly and won’t strip the threads out of the head of the engine. Tighten as much as you can and then put your socket back on the spark plug to tighten it all the way down. Give it an extra snug turn.
  • If you are working with a twin-cylinder engine, repeat the same steps to change the spark plug on the other side of the machine. Once the spark plugs have been changed, reconnect the spark plug wire.

Lawn Tractor Tire Chains

Lawn Tractor Tire Chains

When using your Cub Cadet Lawn Tractor during the winter season, you may find that the tractor tires don’t have the stability and traction needed when the pavement is covered by hard-packed snow or ice. Under these conditions, you can increase the traction by using lawn tractor tire chains.

Most tire chains are used on lawn tractors’ rear drive tires. Since manufacturers have been making snow blowers more and more powerful, they can also provide added grip to 2-stage snow blower tires that would otherwise slide around when under full power.

Not only do tire chains add traction to your rear wheel drive, they also help break up ice on your drive and walkways. Tire chains are highly suited for driveways that are inclined. Since they are made of hardened steel, combined with the weight of the tractor, there is risk of damage if tire chains are used and operated on brick pavers. If you store your Cub Cadet tractor in the garage, it could possibly damage weak floor surfaces.

There are 2- and 4-link chains available, which refer to the spacing between skipped side links. For 2-link spacing, cross chains occur between every two side link chains. For 4-link spacing, cross chains occur between every four link chains.

Which chain is better? That depends on which chain spacing suits your needs. The 2-link spacing tire chains will give more traction because there are more cross links and the tractor’s ride will be steadier. The 4-link spacing chains are generally less expensive, and still provide a little extra traction.

The chain size is the same dimension that is formed into the side of the tire wall. Tire chains are available in every size used for lawn and garden tractor wheels. Some chain sets are meant for more than one tire size, and links may have to be removed with bolt cutters or by bending the connecting links with pliers.

To Install Lawn Tractor Tire Chains you will need:

  • Tire chain set
  • Air compressor
  • Bolt cutters or strong pliers
  • A level area of pavement to work from

Here’s What To Do:

  1. Semi-deflate the tires that you will be installing chains on
  2. Lay the chains out flat on the ground and remove any tangles
  3. Lay the chain over the tire, cross chain hook facing up, and fastener to the outside
  4. Tuck the first cross chain between the front of the tire and pavement
  5. Move the tractor forward until the end fasteners are about axle high
  6. Hook the inside fastener first, remove slack, then hook outside fastener
  7. You want the chain to be hand tight which will extend the life and performance of the tire chains
  8. Fill tires to the proper PSI rated on tire wall – this will seat the chains to proper tension

Any remaining length can be shortened by removing one or more cross sections. Using pliers to pry the cross chain connecting link open and unhook or use bolt cutters.

It is important to check that you have enough clearance in both rear wheel wells for tire chains. There should be, at minimum, three inches of clearance between the tire and the inside wall and any drive components.

If you still need more traction, some tractors have wheel weight kits that mount on the outside of the rim, or “suitcase” styled weights to add to a rear weight bar bracket, if available as an accessory.

Fuel Tips for Cub Cadet Snow Blowers

Fuel Tips for Snow Blowers

Your Cub Cadet snow blower’s fuel system is designed to withstand years of use. However, if you are not mindful of the fuel in your machine and allow it to go bad this can cause starting or running problems and damage to the fuel system. Read more as our experts explain how to avoid fuel-related problems in your Cub Cadet snow blower.

Fuel Recommendation #1 – Store fuel properly

Store your fuel in a clean, plastic, sealed container approved for fuel storage. This will help prevent rust and metallic contaminants from entering the fuel system. Close the vent, if equipped, when not in use and store the container away from direct sunlight. Fuel will deteriorate faster when exposed to air and sunlight.

If it takes longer than 30 days to use the fuel in the container, add a fuel stabilizer when you fill the container.

Fuel Recommendation #2 – Do not use gasoline with more than 10% ethanol

Gasoline containing higher levels of ethanol is corrosive and attracts water, which can cause starting or running problems and damage to your Cub Cadet snow blower’s fuel system. Engines produced for use in outdoor power equipment are not designed for gasoline with more than 10% ethanol. Read your Cub Cadet snow blower owner’s manual for information on the proper fuel to use in your machine.

Fuel Recommendation #3 – Remove fuel for summer storage

When winter comes to an end, drain the fuel out of your Cub Cadet snow blower. After draining, there may still be fuel in the fuel line and carburetor, so start your blower and allow it to run until no fuel is left in the machine.

This is an important step for off season storage because if old fuel is left in your snow blower it will deteriorate and cause problems for your machine. Your blower may not start or run properly and, in some cases, there will be damage to the fuel system.

Fuel Recommendation #4 –Add fuel stabilizer to your fuel storage container

If you use your Cub Cadet snow blower infrequently during the winter, add fuel stabilizer to your fuel storage container. Untreated gas left in your snow blower can deteriorate quickly, causing problems for your machine and the fuel system. Ensuring that the fuel in your Cub Cadet snow blower is stabilized minimizes the chances of deterioration and damage.

When to Sharpen or Replace Your Cub Cadet Lawn Mower Blade

When to Sharpen or Replace Your Cub Cadet Lawn Mower Blade

To achieve a great cut and a healthy lawn, it is essential to regularly sharpen or replace your Cub Cadet lawn mower blade. While many people only need to sharpen their lawn mower blades once every couple of months, people who mow more than once a week will need to increase maintenance to once each month. The exact timing depends on workload, but if you’re not sure how often to perform blade maintenance, there are a few tell-tale signs that will help you stay on schedule.

With the following tricks, you can develop a trained eye and keep your Cub Cadet lawn mower blade up to par all season.

The first and most obvious thing to look for is unevenness in your lawn. When your Cub Cadet lawn mower blade is sharp, your grass should be cut at the same height every time with just one pass of the mower. If you find yourself making multiple passes to compensate for missed patches of grass, a dull blade may be the culprit.

Another way to tell if your Cub Cadet lawn mower blade needs sharpening is by closely inspecting the grass. If you notice that the tip of each grass blade is torn and not cleanly-sliced, it may be time to switch out your blade. Torn tips may also decrease grass health, causing grass to lose its lush, green color to an unhealthy shade of brown.

Lastly—and perhaps most obviously—you can inspect the blade itself. While your Cub Cadet lawn mower blade can usually be salvaged with routine sharpening, it is important to look for large chips or dents in the cutting edge that cannot be smoothed out. Inconsistencies in the blade are likely to tear grass rather than delivering the clean cut that’s important for your lawn.

Also pay attention to the thickness of your Cub Cadet lawn mower blade. Over time, sand, dirt, and other yard debris can erode the blade, causing the metal to weaken and become paper-thin. If you notice this, replace the blade immediately to avoid breakage during mowing, which can cause pieces of metal to fly apart and possibly injure you or other bystanders.

Overall, paying close attention to your lawn and your mower will help greatly in determining when to sharpen or your replace your Cub Cadet lawn mower blade. Remember the signs, perform maintenance regularly, and your Cub Cadet lawn mower blade should cut beautifully every time you mow.

How to Install a Mulch Kit on a Cub Cadet Tractor

How to Install a Mulch Kit on a Cub Cadet Tractor

A mulch kit is a way to convert your Cub Cadet tractor into a mulcher. When you change the tractor’s standard blades to mulching blades, the mulch kit recycles the lawn clippings as you mow and spreads them back onto your lawn. This returns nutrients back into the soil, keeping your grass healthy. Here’s how to install a mulch kit on your Cub Cadet tractor.

Depending on your model number, these instructions may vary.  Be sure to refer to your owner’s manual for detailed instructions, recommended maintenance and safety instructions.

Before performing any maintenance on your machine, engage the parking brake on a flat, level surface and remove the key from the ignition. Disconnect the spark plug wire to prevent accidental starting.

To install a mulch kit on a Cub Cadet tractor, begin by removing the mower deck. Set the deck height to its lowest setting. Pull the right idler pulley to release tension on the deck belt, and then ease the deck belt off the engine pulley.

Use pliers to remove the cotter pin from the front deck lift rod and slide the rod out of the hanger bracket. Remove the hairpin clip securing the right side of the deck to the hanger bracket supporting the cutting deck and release it from the hanger bracket by moving the deck outward and off the hanger rod making sure the deck doesn’t fall. Repeat this step on the left side and slide the deck out from underneath the tractor.

Once the mower deck is off, flip it over to access its underside to prepare to remove the old mower blades. Note: always wear heavy duty gloves when handling blades.

Use a block of wood and wedge it between the blade and the frame of the mower deck. Make sure it’s good and steady because you’ll be applying force. 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.

Once the old blades are removed, you can 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 each blade with the side marked “bottom” or with the part number on it is facing the ground when the mower is in the operating position.

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 Cub Cadet tractor, lift the discharge chute up. Place the mulch plug into the deck discharge chute by fitting the bolt on the rear side of the mulch plug into the hole in the deck.  Move the mulch plug into place, then pull and stretch the retaining plug on the mulch plug over the deck wheel bracket and hook it under the bottom of the bracket.

Slide the deck back under the tractor and reattach the deck. You are now ready to use your Cub Cadet tractor as a mulcher.
