Maintaining your lawn mower is not only keeping your lawn healthy, but protecting your investment. Sharp mower blades give your lawn a nice clean cut. If you mow with dull blades, you can tear the grass and leave it vulnerable to disease and pests.
For gas mowers, you can prolong its life by changing out the motor oil annually. This keeps your motor healthy and clean.
Clean your mower after 3-4 uses. Scrap away grim and stuck on grass/dirt. Use a light oil on and around the wheels and gears to keep things running smoothly.
