To use this tractor with trailer, start by using the front - end loader to pick up hay bales from the field. Lift them up and carefully dump them into the trailer. When you get to the farm, open the flap on the trailer to empty the load. If the engine starts to sound odd, open the hood to check for any obvious issues. Try to look for loose parts or anything that seems out of place. For maintenance, regularly check the oil level and the tire pressure. Keep the tractor and trailer clean after each use to prevent dirt build - up. If you're unsure about any problem, it's best to consult a professional mechanic.
