The recommended oil type for the Gravely G Series 987070 Tractor is SAE 10W-30. This oil provides optimal performance under a wide range of temperatures.
If your tractor is having starting issues, check the battery connections, ensure the fuel tank is full, and inspect the spark plugs for wear or damage.
To change the blades, ensure the tractor is on a flat surface, disconnect the spark plug, lift the mower deck, and use a wrench to remove the blade bolts. Replace with new blades and tighten securely.
The air filter should be checked every 25 hours of operation and replaced every 100 hours or annually, whichever comes first, to ensure optimal engine performance.
Before winter storage, clean the tractor thoroughly, change the oil, add fuel stabilizer, remove the battery, and store in a dry place. Cover the tractor to protect it from dust and moisture.
To adjust the cutting height, locate the height adjustment lever on the side of the mower deck. Move the lever to the desired cutting height position. Ensure both sides are set equally for an even cut.
Excessive vibration can be caused by unbalanced blades, loose parts, or debris caught in the mower deck. Inspect and balance the blades, tighten any loose bolts, and clean the deck thoroughly.
Use a tire pressure gauge to check the tire pressure regularly. Inflate the tires to the manufacturer's recommended pressure, typically found in the operator's manual or on the tire sidewall.
The Gravely G Series 987070 Tractor is designed for use on moderate slopes. Exercise caution and avoid operating the tractor on slopes greater than 15 degrees to prevent tipping or loss of control.
Before each use, check the brakes, steering, and tires. Ensure that all safety guards are in place, and inspect the blades for damage. Confirm that all controls operate smoothly and properly.
