To change the oil, first ensure the tractor is on a level surface. Warm up the engine slightly to thin the oil, then turn it off. Locate the oil drain plug and place an oil pan beneath it. Remove the drain plug and allow the old oil to completely drain out. Replace the drain plug securely. Remove the oil filter and replace it with a new one. Finally, refill the engine with the recommended type and amount of oil.
The recommended tire pressure for the Gravely 985 Series 985110 1999 Tractor is typically between 12-15 psi for the front tires and 10-12 psi for the rear tires. Always refer to the sidewall of the tire or the owner's manual for the most accurate information.
If your tractor won't start, check the battery for charge and connections for corrosion. Ensure the fuel tank has clean, fresh fuel. Inspect the spark plug for fouling and replace if necessary. Verify that the air filter is clean and not clogged. If the problem persists, consult the ignition system and fuel lines for further issues.
The recommended hydraulic fluid for the Gravely 985 Series 985110 1999 Tractor is typically a high-quality, anti-wear hydraulic oil with a viscosity grade of ISO 46 or ISO 68. Always check the owner's manual for specific recommendations.
The air filter should be inspected before each use and cleaned or replaced every 100 hours of operation, or more frequently in dusty conditions. Regular maintenance ensures optimal performance and longevity of the engine.
To adjust the cutting height, locate the height adjustment lever or knob on the tractor. Move the lever or turn the knob to the desired cutting height position. Ensure that both sides are adjusted equally to maintain an even cut.
If the tractor overheats, stop the engine immediately and allow it to cool. Check the coolant level and refill if necessary. Inspect the radiator and cooling fins for blockages and clean them if needed. Ensure the fan belt is intact and functioning. If the problem continues, consult a professional technician.
To replace the mower blades, ensure the tractor is on a stable surface and the engine is off. Lift the mower deck using the appropriate lift mechanism. Use a wrench to remove the blade bolt, then take off the old blade. Install the new blade, making sure it is oriented correctly, and tighten the bolt securely.
The maintenance schedule includes checking oil and fluid levels before each use, changing the oil and filter every 50 hours, inspecting and cleaning the air filter every 100 hours, checking tire pressure regularly, and inspecting belts and blades for wear. Refer to the manual for a detailed schedule.
To improve fuel efficiency, ensure the engine is well-maintained with regular oil changes and clean air filters. Keep the tires properly inflated and blades sharp. Avoid overloading the tractor and operate at a consistent speed. Regularly check for and repair any leaks in the fuel system.
