Pouring oil to riding lawn mower

It's crucial to check and replace the engine oil on your riding lawnmowers as part of routine maintenance. The engine of your machine will operate as intended and last longer if you conduct this maintenance as directed in your owner's manual. For changing the oil, follow the steps listed below.

1. Position The Riding Mower

Park riding mower on a flat area. Apply the parking brake and remove the key. Place the key in a safe location.

2. Remove The Hood

Removing the hood will allow you easy access to your engine. Disconnect the light harness. Then, lift the hood off the frame and put it in a safe place for later reinstallation.

3. Check The Engine Temperature

Allow the engine to rest for some time to cool off. Verify the engine has cooled off by touching the outside casing but still do it with caution because it still might be hot.

4. Prepare A Collection Container

Place a catching basin underneath or on the side near the draining port of the riding mower. Only use an appropriate oil collection container as noted in your equipment’s manual. You can also look for a basin or bucket that is big enough to catch the used oil of your riding mower.

6. Drain The Oil

It will be necessary to drain the existing oil. To drain the oil, first, pry open the protective cap on the oil drain. Next, insert the oil drain tube and twist. Then, open the oil drain spout and let it drain. 

Wait for the oil to drain. After that, close the oil spout and remove the oil tube. Recap the oil drain valve's end to prevent debris from getting into the drain port.

Another way is using the siphon pump. Remove the oil fill cap/dipstick first. The dipstick is similar to taking a sword out of its sheath. Then, insert the pump’s black tube into the engine's oil fill tube and the pump’s orange tube into the oil pan or collection container.

Avoid overfilling as this may result in excessive smoke and engine damage.

9. Check The Oil Levels

New oil is viscous and needs to be distributed throughout your engine. After some time has passed, use the dipstick to check the oil level once more.

You may find that the oil level indicated on the dipstick has lowered as the oil moved through the engine. If it has fallen below the full line, add more oil. 

Pull back the dipstick from the tube. Prepare a rag or paper towel and wipe any oil from the dipstick's tip. Two marks may be seen at the tip of the dipstick. The lower line shows that the oil level is one quart low and the upper mark indicates it is full.

Push the dipstick all the way down the tube. Now take it out again and carefully inspect the tip and check how far the oil is covered. 

Your engine has enough oil if the level is between the two marks. It's time to add more oil if it is at or below the low mark. But much better if it is in the full mark. After that put back the dipstick and tighten it.

10. Return The Hood

Install the hood back into place and reconnect the light harness and you are ready to mow.
