Toro Z Master Z150 52-inch 74165 Operator's Manual

To adjust the cutting height, locate the height adjustment lever on the mower deck. Move the lever to your desired cutting height position, which is clearly marked on the mower. Make sure the deck is level for an even cut.
First, check the fuel level and ensure there is fresh gasoline in the tank. Verify that the battery is charged and the connections are clean and tight. Inspect the spark plug for wear or damage and replace if necessary. Ensure all safety interlocks are engaged.
It is recommended to change the oil after the first 5 hours of use, then every 50 hours of operation or at the beginning of each mowing season. Always use the oil type specified in the owner's manual.
Use high-lift blades for regular mowing to enhance grass lift and discharge. For mulching, install Toro's specific mulching blades designed for the Z Master series for optimal performance.
Check the tire pressure to ensure all tires are equally inflated. Inspect the mower deck for level alignment. Ensure the blades are sharp and not worn out or damaged. Adjust the deck as needed following the instructions in the manual.
Perform a thorough inspection of the mower, checking belts, blades, and tires for wear. Change the oil and oil filter, and replace the air filter. Also, lubricate all moving parts and check the battery charge.
First, disconnect the spark plug to prevent accidental starting. Remove the mower deck and locate the drive belt. Follow the tension release procedure in the manual, remove the old belt, and install a new belt following the correct routing path.
Check for any debris lodged in the deck or around the blades. Inspect the blades for damage or imbalance. Ensure the spindle assembly is not worn out. Tighten any loose bolts or nuts on the deck assembly.
Keep the mower blades sharp and properly balanced. Avoid mowing with a full throttle when not necessary. Regularly maintain the engine and replace filters as needed. Mow during cooler parts of the day to reduce engine stress.
Always wear appropriate safety gear including eye and ear protection. Do not operate the mower on wet grass to avoid slipping. Keep bystanders away from the mowing area. Regularly inspect safety interlocks and ensure they are functioning properly.
