Some additional tips that will help you keep your mower in great shape:

The lubrication needs of an air-cooled engine are more severe than an automotive engine. Although automotive oil can be used, most OEM oils are specifically formulated with greater anti-wear additives for the needs of your engine. Even if you use an extended interval oil, do not run that oil longer than recommended. Although the base oil and additives may be intact, the dusty environment of a lawnmower means fine dust (smaller than the filter size) can accumulate in the oil and so it should be changed in a timely manner.

DO NOT use compressed air to clean out an air filter. This will damage the filter and allow dust to pass through it. The best way to clean a filter is the gently tap it to remove loose debris. Be careful to not let grit fall into the engine when removing the filter. Some aftermarket filters do not seal on the intake of the engine very well and can lead to dust ingestion and may void your engine warranty.

If you don’t know what your engine spec number is and you need to lookup parts for your engine, the easiest way to find it is to search you mower serial number at and scroll to the bottom of the page. Your engine serial number and spec number will be listed there. Otherwise, you can look for the spec number on the engine. Most Kawasaki and Kohler engines are on the side of the shroud and most Briggs are on the valve cover.

Performing an end-of-season or preseason preventative maintenance can save you a lot of time:

  1. Check belts for any wear. Replacing a belt in the shop is a lot easier than dragging a mower off a customer’s property or fixing it on-site.
  2. Check idler pulleys and spindles for worn or rough bearings.
  3. Check for any leaks.
  4. Service all oil and filters.
  5. Check all pivots and linkages for wear.
  6. Inspect the mower for any missing or loose hardware.
  7. Worn tires are more likely to receive a puncture and will lead to more skidding on your customers’ properties. Replace worn tires and deck wheels and smooth operation will greatly extend the life of your tires.

Check your owner’s manual for a complete maintenance schedule. This is only a snapshot of a few of the most common maintenance points on your mower. You manual will have the latest up-to-date information.
