You should never turn your four-stroke petrol mower on it’s side. This could cause oil to leak into the cylinder and very often drowns the air filter. It would then be very hard to start and the air filter would need replacing if it’s a cartridge type. When cleaning the mower, always put it in the ‘wheelie’ position ie. on it’s back wheels, front wheels in the air, spark plug up. Using a plastic spatula, scrape off the grass from under the base. On a hot day put the mower out to air dry. This will extend the life of your chassis.
Always make sure the mower is not running 😉
