To maintain your John Deere 134, regularly check the oil levels, clean or replace air filters, inspect and replace worn belts, and ensure all nuts and bolts are tightened. Keep the mower deck clear of debris and sharpen the blades as needed. Regularly check tire pressure and battery charge.
If your John Deere 135 won't start, check the battery connections and charge or replace the battery if necessary. Ensure the fuel is fresh and the fuel filter is not clogged. Examine the spark plug for wear and replace if needed. Also, check for any blown fuses or loose wiring connections.
Uneven cutting can be caused by a number of factors. Inspect the mower deck to ensure it's level. Check that the blades are sharp and not bent. Verify tire pressure is consistent on both sides. Adjust the cutting height settings if necessary.
To store your John Deere 135, clean the mower thoroughly and remove any grass clippings. Drain the fuel or add a fuel stabilizer. Disconnect the battery and store it in a cool, dry place. Cover the mower to protect it from dust and moisture, and store in a dry, sheltered location.
To change the oil on a John Deere 134, run the engine for a few minutes to warm the oil. Turn off the engine and remove the oil drain plug to drain the old oil. Replace the plug and fill with new oil, checking the level with the dipstick to ensure it's correct. Dispose of old oil responsibly.
Excessive vibration can be caused by unbalanced or damaged blades, loose pulleys, or worn bearings. Check the mower blades for damage or imbalance. Inspect the pulleys and bearings for wear and tighten any loose parts. Replace components as necessary.
The air filter should be checked before each season of use and replaced if it's dirty or damaged. In dusty conditions, inspect and clean or replace the filter more frequently to ensure optimal engine performance.
John Deere 135 mowers are designed to run on regular unleaded gasoline with an octane rating of 87 or higher. Avoid using gasoline with more than 10% ethanol to prevent engine damage.
To improve performance on hilly terrain, ensure that the tires are properly inflated and have good tread. Adjust the cutting height to prevent scalping. Engage the traction control if available, and mow up and down the slope rather than across to maintain stability.
If your John Deere 135 is overheating, check for debris blocking the air intake or cooling fins and clean them. Ensure the engine oil is at the correct level and change it if it's old or dirty. Verify that the cooling fan is functioning properly.
