Most Common Issues (All Models – Gas & Zero-Turn)

• Engine won't start: Check fuel level & quality (use fresh gas, no more than 30 days old); ensure fuel valve open; prime bulb 3–5 times; clean/replace spark plug; check oil level (low oil sensor may prevent start).
• Engine starts but stalls / runs rough: Clean air filter; check spark plug gap; drain old fuel & replace with fresh; inspect fuel lines for cracks; clean carburetor if needed.
• Weak / uneven cut: Sharpen or replace blades; check blade balance; level deck (front-to-rear & side-to-side); adjust tire pressure; avoid cutting wet grass.
• Excessive vibration: Blade bent/damaged/unbalanced – replace immediately; check spindle bearings; tighten blade bolts to spec; inspect engine mounts.
• Self-propelled drive weak / slipping (walk-behind): Adjust drive cable tension; check belt for wear/cracks; clean drive pulley & transmission area; lubricate drive wheels.
• Zero-turn / hydrostatic drive not moving: Check bypass levers in operating position; ensure parking brake released; check fluid level (if applicable); test with engine running at full throttle.

IKON, APEX, ZT-X & Zero-Turn Models (2023–2026)

• One side not driving: Check belt tension & condition; inspect pulley alignment; clean debris from drive system; check hydrostatic fluid if leaking.
• Steering stiff / jerky: Lubricate pivot points & linkages; check tire pressure equal; adjust control levers/neutral position per manual.
• Deck won't engage / blades won't spin: Ensure PTO switch fully on; check deck belt tension & routing; inspect PTO clutch; clean grass buildup under deck.

Riding & Compact Models

• No forward/reverse movement: Check transmission bypass rod/lever; ensure seat safety switch engaged; inspect drive belt; check parking brake fully released.
• Battery won't charge / dead battery: Clean terminals; check alternator output; replace battery if over 3–4 years old; use trickle charger off-season.

Safety note: Always remove spark plug wire before maintenance or blade work. Wear gloves & eye protection. Never operate with missing guards, damaged blades, or bystanders/children nearby. Stop engine & disengage blades before clearing clogs or adjustments.
