Guide to Cleaning Lawn Mower Deck

Guide to Cleaning Lawn Mower Deck

During the operation of the John Deere lawnmower, the grass particles contaminate the blades and the surface of the deck. Therefore, after each grass trimming, it is necessary to thoroughly clean the surface of herbal waste.

In case of drying, the remnants of vegetation may interfere with the normal operation of the blades. All procedures for cleaning the deck must be carried out with the engine stopped. For cleaning, do not use strong substances such as gasoline and thinner. Particular attention should be paid to cleaning the ventilation holes. After the lawn mower shines with cleanliness, you can apply an anti-corrosion spray to the deck and blade.

Some things to keep in mind:

  • Protect electrical and cordless lawn mowers from moisture ingress.
  • It is best to use rags, mild soap, and a damp cloth to clean the equipment with an electric motor.
  • Some lawn mowers are equipped with a self-cleaning deck or a system of simplified washing of the deck, which allows you to simply connect the hose to the body and clean all the insides of the unit from the grass.

Cleaning the Lawn Mower

To ensure that the lawn mower works properly, it is necessary not to forget to keep it in absolute purity. Did you know that the grass juice has a strong corrosive effect for a riding mower? If the cuttings of the mowed grass cover accumulate under the deck, it will quickly cover with rust and break up. Cleanliness should be maintained both at the top and bottom of the deck.

Cleaning the Deck

Remember that you can minimize cleaning work only if you do not mow the wet grass. Dry grass will fall off from the deck so that all cleaning can be done by a blower or an air compressor. Wet grass clippings, as well as stuck plants, are extracted using a deck scraper and a water hose. Some models of devices have a flushing nozzle mounted on the deck, which makes it even easier to clean them.

Engine Cleaning

No less important is the maintenance of engine cleanliness. The motor of the mowers is equipped with air cooling, and the stability of the entire system will depend on the purity of the cooling fins. Dirty fins threaten with overheating and failure of expensive equipment. Cleaning the fins for a push mower involves dismantling the auxiliary external components of the engine, after which it will be possible to apply compressed air for cleaning. If there is no compressed air source, use a soft brush that shows even greater efficiency in many cases.

Other Things to Keep in Mind

The best way to clean mower deck is with water, however, do not direct the hot water jet over bearings, engine parts, and seals – this may cause damage to the mower. To clean the deck, tilt the tool so that the spark plug is facing up. If you overturn the technique sideways, oil may enter the filter or exhaust system, which also leads to serious damage.

How to Care for a Gasoline Lawnmower?

Gasoline lawn mowers are more powerful and mobile but caring for them may require some additional knowledge. Complying with all requirements will allow your lawnmower to always show 100% performance and extend its service life.

Replacement of the Air Filter

The air filter is one of the main elements in the engine, which ensures its stable operation. This element is designed to clean air from dust. If there is no filter, all dirt gets directly into the motor, which can lead to damage. Most often, gasoline lawnmowers use foam or paper air filters. In case of contamination, the first one can be washed in soapy water, wrung out, dried, and reused. The paper filter for zero turn mower must be replaced with a new one.

Important(!):

  • It is recommended to change the air filter 1 time per season.
  • Operation without an air filter or a dirty filter may damage the engine. In this case, the equipment is not subject to a warranty repair.

Replacing the Spark Plug

An important element of the internal combustion engine is the spark plug. This part provides ignition of the fuel-air mixture. Without it, the work of the motor is impossible. Many manufacturers recommend replacing this element before the beginning of each season.

Replacing Spark Plug on Lawn Mower

When inspecting the spark plug, pay attention to its appearance. Usually, a normal working plug has an electrode gap of 0.7–0.8 mm. If the electrode formed a black deposit, there were traces of fuel or oil, then such a part must be replaced. Light brown carbon, the absence of traces of oil indicate the normal operation of the spark plug.

Important(!):

  • It is recommended to replace the spark plug once a year.
  • Do not disassemble the plug when the engine is running, nor can it be twisted until the engine is completely cooled.

Replacing the spark plug is done as follows:

  • It is necessary to detach the cap of the plug, remove the dirt from it
  • With the help of a plug key, you need to unscrew the part
  • Install a new plug and twirl it with your hands
  • Then firmly tighten the plug with a key

Looking After an Electric or Cordless Lawn Mower

Electric and battery lawnmowers (Husqvarna, Honda, John Deere, etc.)  require less attention than gasoline mowers but certain rules of care exist for them as well. If you are using an electric lawn mower, then you need to pay extra attention to the cord. It should not be pinched or tied in a knot, avoid damaging it with a blade. When the work is completed, carefully wind the cable. Many models are equipped with special holders for the wire.

Important(!):

  • Damage to the cord or body of an electric lawn mower may result in electric shock.
  • The main enemy of electrical appliances is water so when working with an electric lawnmower, moisture should be avoided inside the deck. It is forbidden to work in the rain and in adverse weather conditions. Also, you can’t mow wet grass.

How to Prepare a Lawn Mower for Winter?

To store lawn mowers during the cold season, several rules must be observed, so that the device will again be in the best shape next spring. By the way, here are Useful Tips on How To Winterize Your Lawn – check it out!

Proper preparation for winter is the key to the long and trouble-free operation of machinery. You need to conserve the equipment if you have not worked on it for more than 1.5 months. Follows these steps before putting your lawn mower away:

  • Drain the fuel from the fuel tank, then start the engine, and let it run until it stops. This way, you’ll remove the remains of fuel from the carburetor.
  • Carefully clean the lawn mower.
  • Disconnect the spark plug, pour in a hole 10 ml–20 ml (a tablespoon) of oil. Gently pull the handle of the starter 3–4 times to lubricate all internal elements.
  • Put the spark plug into place without tightening it, slowly pull the starter again until you feel resistance to close all the dampers in the engine.
  • Store the mower in a dry place, grease all corrosion-prone components, and control levers.

Important(!)!:

  • You can use a syringe to pour oil into the mower. Also, there are special syringes-lubricators you can buy.
  • Gasoline or fuel mixture, which is stored for more than 30 days, are oxidized, resulting in them accumulate harmful tar, which clogs the carburetor and can lead to the engine failure.
