Maintenance Tips
- Check and replace the mower deck belt every 200-300 hours of use, or annually, to maintain optimal cutting performance.
- Sharpen mower blades at least twice per season, or more frequently if you mow in sandy or abrasive conditions. Dull blades tear the grass and make it more susceptible to disease.
- Change the engine oil and filter every 50 hours of operation, or at least once a year before storing the mower for the winter.
- Before storing the S170 for the off-season, stabilize the fuel with a fuel stabilizer to prevent gumming and corrosion in the fuel system.
