Spring and summer mowing season can be a busy time. To save money on costly lawn mower repairs, it is a good idea to keep a schedule of your lawn mower maintenance so you can keep your lawn mower engine in top shape and keep your lawn looking great year after year. Your mower engine is important to the life and performance of your equipment.
Here are some easy steps you can follow by season to keep your lawn mower in top shape. Follow the seasonal or hourly intervals, whichever comes first. More frequent service is required when operating your lawn mower in dirty or dusty conditions. For specific questions about your Cub Cadet, Husqvarna or Huskee mower engine, refer to your owner’s manual, contact the manufacturer, or visit your local Tractor Supply Co. store.

When the cold weather of fall and winter arrives, it is time to winterize your lawn mower. Prevent damage to hoses and gaskets caused by changes in temperature by adding or replacing key fluids and following these steps:
