To change the oil, first ensure the tractor is on a level surface. Remove the oil fill cap, place a container under the oil drain valve, and open it to allow the old oil to drain completely. Replace the drain valve, add new oil, and check the level with the dipstick. Ensure proper disposal of used oil.
Use unleaded gasoline with a minimum octane rating of 87. Avoid using gasoline with more than 10% ethanol to prevent engine damage.
If the tractor won't start, check the battery connections for corrosion, ensure the fuel level is adequate, and verify that the spark plug is in good condition. Additionally, ensure the seat switch is engaged and the PTO is off.
Perform regular maintenance, including checking and replacing the oil every 50 hours of operation, inspecting the air filter every 25 hours, and checking the tire pressure monthly. Refer to the owner's manual for a detailed schedule.
To replace the mower deck belt, lower the deck to its lowest position, remove the old belt from the pulleys, and install the new belt around the pulleys in the correct configuration. Ensure the belt is properly tensioned before use.
Sharpen the mower blades regularly, ensure the deck is clean and free of debris, and adjust the cutting height appropriately for the grass type. Also, mow when the grass is dry to prevent clumping.
Excessive vibration may be due to unbalanced blades, loose components, or damaged belts. Check and tighten all bolts, inspect the blades for damage, and replace any worn belts.
Clean the tractor thoroughly, change the oil, and add fuel stabilizer to the tank. Store the tractor in a dry place and disconnect the battery to prevent it from discharging over the winter.
If the steering is loose, check the steering linkage for wear and tighten any loose connections. Adjust the tie rods to ensure proper alignment. Refer to the manual for specific adjustment procedures.
The recommended tire pressure for the Broadmoor 738 is typically around 10-14 psi for the rear tires and 12-16 psi for the front tires. Check the sidewall of the tire for specific manufacturer recommendations.
