Steps To Drain Oil From Lawn Mower

As a lawn mower owner, you might face the daunting task of draining oil from it. An essential maintenance step, replacing old oil with new oil helps to keep the mower running smoothly and efficiently. Several steps need to be carried out to drain oil from the lawn mower properly.

Let’s discuss each of them in detail under the subheading: steps to drain oil from lawn mower.

Remove Drain Plug/ Oil Cap

The first step is to locate the drain plug or oil cap on your mower. Follow the user manual to find it. Every lawn mower has a plug on its underbelly that allows you to have access to the oil chamber.

Use a ratchet and socket to remove the drain plug or oil cap located on the mower’s underside. This action will enable the oil to flow out and into the drain pan below.

Place Drain Pan Beneath Mower

Before proceeding further, make sure to place a drain pan directly under the mower’s oil exit hole. The pan’s size should be sufficient to hold all the old oil, so choose the right size. You don’t want to make a mess by letting the oil spill all over the lawn or garage floor.

Tilt Mower To Pour Old Oil Into The Drain Pan

Once the oil chamber is fully drained, empty the collected used oil from the pan into a suitable container. Then, tilt the lawn mower towards the direction of the draining pan to pour the rest of the old oil out completely.

Make sure to shake the device gently to drain all the remaining oil from the engine. This step is crucial to prevent any potential harm caused by residual oil in the oil chamber.

Clean The Oil Drain Plug

With the old oil fully drained, clean the drain plug with a clean cloth and check it for damage. You can now replace the drain plug if necessary.

Pour New Oil Into A Reservoir

Now it’s time to refill the chamber with fresh oil. Using a funnel, pour the right amount of oil into the mower’s oil chamber. Check the user manual to find the amount of oil you need to fill for your specific model.
