To start the Gravely 50120 Tractor, ensure the transmission is in neutral, turn the ignition key to the 'start' position, and release once the engine starts. Always check fuel and oil levels before starting.
Perform regular maintenance every 50 hours of operation, including oil changes, air filter cleaning, and checking tire pressure. Inspect belts and blades for wear every 100 hours.
If the engine doesn't start, check the battery charge, ensure fuel is fresh, and inspect the spark plug for wear or damage. Ensure the choke is properly adjusted.
Use SAE 10W-30 oil for optimal performance in most conditions. In colder climates, consider using SAE 5W-30. Refer to the owner's manual for specific recommendations.
To sharpen the blades, remove them from the mower deck, secure them in a vice, and use a metal file or grinder to sharpen the edge. Be sure to balance the blade before reinstalling.
Excessive vibration can be caused by unbalanced blades, loose parts, or worn bearings. Inspect the blades for damage, check all bolts and connections, and replace worn bearings.
Adjust the cutting height by moving the deck height adjustment lever to the desired position. Refer to the manual for specific height settings and adjustments procedures.
Check the transmission fluid level and ensure it is at the correct level. Inspect and adjust the drive belt tension if necessary. If problems persist, consult a professional technician.
To improve fuel efficiency, keep the engine well-tuned, maintain proper tire pressure, and clean air filters regularly. Avoid idling the engine for extended periods.
Always wear appropriate safety gear, such as goggles and ear protection. Avoid operating on steep slopes, and be cautious of obstacles. Keep bystanders at a safe distance.
