Murray 2690891 LT150RDFR Parts Manual

To start the tractor, ensure that the parking brake is engaged, the PTO lever is in the 'off' position, and the transmission is in neutral. Then, turn the ignition key to the 'start' position until the engine starts.
Use SAE 30 oil for the engine when operating in temperatures above 40°F. For colder temperatures, use SAE 5W-30 oil. Always check the owner's manual for specific recommendations.
It is recommended to change the engine oil every 50 hours of operation or at least once a season, whichever comes first.
If the tractor does not start, check the battery connections, ensure the fuel tank is not empty, verify that the spark plug is clean, and check the fuse. Refer to the owner's manual for detailed troubleshooting steps.
To adjust the cutting height, locate the height adjustment lever on the tractor. Move the lever to the desired position, which is marked with numbers indicating different height levels.
Regularly clean the mower deck to prevent grass build-up. Check and sharpen the blades as needed. Lubricate the spindles and inspect the belt for wear and tear.
Stop the tractor immediately and allow the engine to cool. Check the coolant levels and inspect the radiator for debris. Ensure that the engine oil is at the recommended level.
To improve traction, use tire chains and ensure that the tires are properly inflated. Ballasting the rear of the tractor can also help maintain traction on slopes.
To replace the drive belt, remove the mower deck and the belt guards. Release the belt tension and remove the old belt. Install the new belt following the routing diagram provided in the manual and reassemble the components.
Regular maintenance includes checking and changing the oil, inspecting the air filter, checking tire pressure, lubricating moving parts, and inspecting belts and blades. Follow the maintenance schedule provided in the owner's manual.
