In general, the engine oil, air filter, blades, and grass bag should be checked before each use. Maintenance requirements will vary by model. The owner's manual provides a maintenance schedule.
The Proper Mower Maintenance
Generally, the Honda mower must be carefully inspected at the beginning of the season. Depending on the usage, cables may need adjustment, the blades may need to be sharpened or replaced and engine oil changed. The blades and oil should be checked before or after each mowing. At the end of the season, the mower should prepared for storage as detailed in the owner manual.
The Importance of Sharpen the Blade
The jagged tips produced by a worn mower blade are also open wounds for the invasion of diseased organisms. A worn or dull blade produces a poor cut, so a properly sharpened blade is also a balanced blade, which reduces vibration, extends the life of the mower, and makes it more comfortable to use.
The Signs of a Worn Mower Blade
A worn or dull mower blade will tend to shred the grass leaf rather than cutting it cleanly. It causes a jagged tip that turns brown rapidly, and it gives the entire lawn a brownish or tan appearance for several days. The turfgrass might actually appear to be diseased or stressed, but the green color will gradually be restored as the grass leaves grow.
