Tip: Always refer to the engine manual for specific engine maintenance procedures.

Mower Deck Operation

Proper deck operation ensures even cutting and extends blade life.

Engage PTO only when seated with parking brake set.
Adjust cutting height to desired setting before starting mower.
Mow at full throttle for best cutting performance.
Overlap cutting passes by 2-3 inches for even coverage.
Disengage PTO when crossing driveways or non-grass areas.
Clean underside of deck after each use to prevent rust and buildup.

Blade Sharpening: Remove spark plug wire. Tip deck safely. Remove blades with socket wrench. Sharpen at 22-degree angle; balance before reinstalling.

Storage & Winterization

Prepare mower for extended storage (e.g., winter).

Clean entire mower, especially underside of deck.
Change engine oil and filter.
Add fuel stabilizer to gas tank and run engine for 5 minutes to circulate.
Disconnect battery negative cable; store battery in cool, dry place.
Store in dry, covered location; consider using a mower cover.

CAUTION! Do not store with fuel in tank for more than 30 days without stabilizer. Gasoline can degrade and damage fuel system.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Engine won't start	Dead battery, empty fuel tank, safety switch engaged	Charge/replace battery; add fuel; ensure PTO disengaged and brake set.
Poor cutting performance	Dull blades, low engine speed, clogged deck	Sharpen blades; operate at full throttle; clean deck underside.
Excessive vibration	Unbalanced blade, loose blade or spindle	Stop engine immediately. Check blade balance and tightness; inspect spindle.
Loss of power	Dirty air filter, old fuel, clogged fuel filter	Replace air filter; drain old fuel; replace fuel filter.
Hydrostatic transmission sluggish	Low fluid, drive belt loose	Check fluid level; inspect and adjust drive belt tension.
