At Lawnmowers for Africa we service, repair and sell a broad range of Lawnmowers. It is important to take care of your lawnmower to ensure it runs smoothly for many years. Ideally the engine oil and filters should be changed once a year, every spring or summer when they work their hardest. Changing the oil is one of the small things you can do to avoid the engine wearing out at an accelerated rate. Only taking a few hours to complete, it is well worth the time and effort to prolong the life of your lawnmower.
