Why do you need to regularly drain a lawnmower?

We are talking here about the thermal mower, which therefore has a fuel-consuming engine. Fuel leaves deposits and dirty your engine, and all of your mower’s mechanics also require maintenance to keep your engine running. With the use of your mower, the engine oil becomes sticky and loses its protective properties against the mechanical parts of your mower’s engine.

In general, the manufacturers advise you to do it every 50 hours of use, if you are not used to counting your mowing hours, do not panic, one to two oil changes per year should be enough to maintain the mechanics of your mower.

What equipment should I use to drain a lawnmower

A simple equipment is required to drain your mower. In fact, you will need:

  • A plastic container
  • filter wrench 
  • An oil filter
  • container
  • Of engine oil 
  • Of protective gloves for your safety
  • There are also manual suction pumps 

To purchase the equipment necessary to drain your lawn, there is also the drain kits Clipper specially designed for it at low prices:

  • 4-stroke engine oil change kit
  • An  oil change kit 


Step 1: Unplug the spark plug and tip your mower

Disconnect the spark plug for safety. Then tilt your mower  45 ° to the side of the oil drain plug located on the lower part of the engine oil pan. Do not overturn the mower completely if the fuel tank has not been drained beforehand. Secure it in this position.

Step 2: Place the drain pan under your mower and unscrew it with the appropriate key

You need to locate the lower drain plug and place the drain pan well below it.

Step 3: Let the oil flow to the last drop

Before draining, we advise you to run the mower engine for ten minutes so that the oil heats up and is more liquid and therefore easier to empty. This action also promotes the evacuation of impurities which could be in the oil pan.

Let the engine cool down. If you want to tilt your mower to change the oil, the fuel tank must be empty and the spark plug facing up. Put on protective gloves and disconnect the spark plug wire, place the suppressor as far as possible from the spark plug.

Then open the cap using a suitable key and let the oil drain into a container. When all the oil has come out of the engine, close the cap. Store the used oil and deposit it in a specialized place for recycling (for example in a recycling center).

Do not hesitate to let the oil drain for a while, the less it will remain, the better the draining. You can also let it drain overnight and resume emptying the next day.

Step 4: Replace the plug and check the condition of the drain joint

If the drain seal is too worn, it must be replaced with a new seal. Otherwise, the oil may leak out because the closure of the cap will no longer be watertight.

Step 5: Replace the oil filter

If your mower has an oil filter, it must be changed. Once the oil is completely drained, you must change the oil filter if your equipment has it. To do this, first, remove the oil filter with a filter wrench and collect the oil in the filter using a container. Then you have to oil the rubber seal of the new filter. Finally, screw on the new oil filter, without tightening it too much, by approaching it by hand and then tightening it using a filter wrench.

You can have two configurations:

For engines without an oil dipstick tube:

Once the equipment is parked on a flat surface, pour up to the thread of the filler cap and screw the cap back on, or follow the user manual of the engine manufacturer which tells you the volume of oil to be poured.

For engines with oil dipstick tube:

Pour the oil gently, let the oil go down into the engine, wipe the tongue with a clean cloth, screw the dipstick, unscrew the dipstick, see if the oil level is between the 2 notches of the tongue. If not, pour a little more oil and so on.

Step 6: Close the top cap and plug in the spark plug

Once the oil is poured, close the oil cap or the oil dipstick cap. Then clean the spark plug, reassemble it, and finally reconnect the suppressor.

Step 7: Check the oil level one last time and start your mower

Your mower is ready to start, draining is finished!
