To change the oil, first warm up the engine to thin the oil for easier drainage. Turn off the engine and remove the oil drain plug located underneath the tractor. Let the old oil drain completely, replace the drain plug, and refill with the recommended oil type and quantity as specified in the manual.
The Gravely 985301 1995 Tractor is designed to run on unleaded gasoline with an octane rating of 87 or higher. Avoid using ethanol blends higher than 10% to prevent engine damage.
If your tractor won't start, check the battery connections for corrosion and ensure they are tight. Verify that the fuel shutoff valve is open and the fuel tank has gasoline. Inspect the spark plug for wear or damage and replace if necessary.
The recommended tire pressure for the Gravely 985301 Tractor is typically around 12-15 PSI for the front tires and 10-12 PSI for the rear tires. Always refer to your owner's manual for the exact specifications.
To adjust the cutting height, locate the height adjustment lever on the mower deck. Move the lever to the desired position, ensuring it clicks into place securely. Refer to the deck height chart in your manual for exact measurements.
Regular maintenance includes checking and changing the oil every 50 hours of operation, cleaning or replacing the air filter every 25 hours, and inspecting the spark plug every 100 hours. Lubricate moving parts and inspect belts and blades regularly.
To replace the drive belt, first ensure the tractor is off and parked on a flat surface. Remove the mower deck and locate the drive belt. Release the tensioner pulley and remove the old belt. Install the new belt, ensuring it is routed correctly, and re-tension the pulley.
Excessive vibration may be caused by unbalanced or damaged blades. Inspect the blades for damage or wear and replace if necessary. Ensure the blades are properly balanced and securely attached. Check for loose bolts and mounts on the tractor.
Maintain your tractor by regularly tuning the engine, changing the oil, and keeping the air filter clean. Ensure the tires are properly inflated and avoid overloading the tractor. Operate at steady speeds and avoid excessive idling.
Check the transmission fluid level and add if necessary. Inspect the linkage for any obstructions or damage. If the issue persists, the transmission may need professional servicing to diagnose internal problems.
