Mowing Instructions

For best results, mow when grass is dry.

  1. Adjust cutting height: Higher for first cut of season or uneven terrain.
  2. Engage blades: With engine at full throttle, pull PTO switch.
  3. Mow in overlapping strips: Change pattern each time to avoid ruts.
  4. On slopes: Mow up and down, not across. Use low speed.
  5. Disengage blades when crossing driveways or gravel.

Tip: Keep deck clean for optimal airflow and cut quality.

Engine Care

Regular maintenance ensures long engine life.

  2. Air filter: Replace paper element; clean foam pre-cleaner if equipped.
  3. Spark plug: Gap at 0.030 inches; replace if worn.
  4. Fuel system: Use fuel stabilizer if storing over 30 days. Replace fuel filter annually.

WARNING! Never run engine without oil. Disconnect spark plug wire before performing maintenance.

Deck Maintenance

A clean, balanced deck provides even cut.

  1. Blade sharpening: Remove deck, secure blade, sharpen at original angle (balance afterward).
  2. Deck cleaning: Scrape off grass clippings and mud after each use.

CAUTION! Wear gloves when handling blades. Ensure deck is securely supported during removal.

Storage

Proper storage prevents deterioration during off-season.

  1. Fuel: Add stabilizer and run engine 5 minutes, or drain tank and carburetor.
  2. Battery: Remove, clean terminals, store fully charged in cool, dry place.
  3. Deck: Clean thoroughly, apply light oil to underside to prevent rust.
  4. Tires: Inflate to proper pressure; store on blocks to relieve weight.
