Summers typically bring scorching temperatures and dry turf conditions that can challenge even the most reliable equipment. Whether you’re using a commercial lawn mower on expansive properties or maintaining a smaller residential plot, proper mower adjustments, routine system checks, and rigorous safety precautions are essential. Below, we’ve outlined best practices to keep your equipment running smoothly and ensure your well-being in the sun.
- Understand the Impact of Heat and Drought
- Grass Stress: Hot, dry weather often places turfgrass into a semi-dormant state. Cutting too low can scalpel the grass, leading to brown patches and thin stands.
- Increased Debris: Dry soil can create dusty conditions and more airborne particles, accelerating wear on engine components and filters.
- Engine Load: High ambient temperatures make it harder for engines to cool themselves, increasing the risk of overheating.
- Mower Adjustments for Optimal Cut
Raise Step-by-Step Cutting Height
Set your cutting deck slightly higher than usual—about 3.5 to 4 inches when possible. A taller cut shade the soil, reducing moisture loss and protecting grassroots.
Sharpen Blades and Inspect Cutting Edges
Sharp blades ensure a clean cut and reduce plant stress. Inspect blade tips for nicks or bends. Replace or sharpen them using genuine lawn mower parts for consistent performance.
Balance the Blades
An unbalanced blade can cause vibration leading to premature wear on bearings and spindles. After sharpening, always re-balance blades to factory specifications.
- Essential System Checks Before Mowing
Air Filter and Cooling Fins
In dusty conditions, the air filters clog quickly, thus restricting airflow and straining the engine. Clean or replace the filter regularly. Also, clear debris from engine cooling fins to maintain optimal heat dissipation.
Oil and Fuel Inspection
High heat degrades oil faster. Check oil levels before each use and adhere to recommended change intervals. Use fuel stabilizers if fuel may sit in the tank during prolonged breaks.
Belts, Pulleys, and Deck Spindles
Inspect mower belts for cracking or glazing and ensure proper tension. Grease pulleys and spindles according to the manufacturer’s schedule to prevent seizing in high temperatures.
Tire Pressure and Traction
Hot pavement or dry grass can alter tire pressures, affecting mower stability. Check and adjust pressures to recommended settings to maintain traction and deck level.
- Cooling and Hydration Strategies
- Engine Coolant: For liquid-cooled engines, verify coolant levels and condition. Look for leaks before starting up.
- Hydration Stations: Keep bottled water or sports drinks readily accessible. Plan mowing routes with shade breaks every 15–20 minutes.
- Shade Covers: If your commercial lawn mower has a rollover protection system (ROPS) or canopy option, use it to reduce sun exposure.
- Personal Safety Precautions
Dress for the Heat
- Wear light-colored, moisture-wicking clothing and a wide-brimmed hat.
- Choose high-traction, breathable work boots.
Sunscreen and Eye Protection
Apply broad-spectrum SPF 30+ sunscreen on exposed skin. Use UV-blocking sunglasses or a face shield to guard against glare and debris.
Rest and Watch for Heat Illness
Schedule mowing for early morning or late afternoon when temperatures dip. Know the signs of heat exhaustion (dizziness, nausea) and heat stroke (rapid pulse, confusion). Stop work immediately and seek shade if symptoms occur.
