Gravely Pro-QXT 985910 2016 Operators Manual

To start the Gravely Pro-QXT 985910, ensure the transmission is in neutral, the PTO is disengaged, and the parking brake is set. Insert the key into the ignition and turn it clockwise to start the engine.
Check the battery connections for corrosion, ensure fuel is reaching the engine, and verify that the spark plug is clean and properly connected.
Change the oil every 50 hours of operation or at the start of each season, whichever comes first. Use a high-quality SAE 10W-30 oil.
Ensure the engine is running at full throttle and check the PTO switch and connections for damage. Also, inspect the PTO belt for wear or damage.
Use unleaded gasoline with an octane rating of 87 or higher. Avoid using E85 or ethanol-blended fuels with more than 10% ethanol.
Clean the tractor, perform all necessary maintenance, add a fuel stabilizer, and store it in a dry, covered area. Disconnect the battery if storing for an extended period.
Refer to the operator's manual for specific tire pressure recommendations, but typically front and rear tire pressures should be maintained at 12-15 psi.
To adjust the cutting height, reposition the cutting deck height adjustment lever to the desired position. Ensure the deck is level for an even cut.
Excessive vibration can be caused by an unbalanced blade, worn belts, or loose components. Inspect these areas and replace or tighten as necessary.
To change the spark plug, disconnect the spark plug wire, remove the old plug using a spark plug socket, and install a new plug, ensuring it is properly gapped. Reconnect the wire.
