Troubleshooting your MTD tractor's engine at home can prevent unnecessary and costly repairs. For more severe engine issues, you should contact a professional, but you can save time and money by following our simple MTD Tractor Troubleshooting Guide.
1. The tractor's engine won't crank at all.
This could be happening for five different, but simple problems to fix:
- Check to be sure the safety switch button is depressed, the deck completely disengaged, and the parking brake is fully engaged. You should be sitting in the operator's seat while checking these items.
- Make sure your battery is properly installed. Proper installation is as follows: negative terminal attached to the black ground wire. The positive terminal is attached to the big red wire going to the solenoid. Make sure your battery is fully charged before installing.
- If you suspect your battery is weak or even dead, check the fluid levels. If you find that the fluid is low, fill just below the split rings with water. Fully charge the battery.
- Think it might be a blown fuse? Check the fuse box for loose connections, and pinched or bare wires. Replace with an automotive type fuse if necessary.
- The problem may also be caused by a loose engine round wire. Check to make sure the black ground wire is running from the engine to the frame or mounting bolt.
2. The engine will crank, but not start.
Try these four easy fixes:
- Ensure the throttle/choke is in the starting position.
- Do you have enough gas? If the tank is properly fueled, check to see if the fuel line or filter is compromised by debris or dirt. Clean your fuel line and replace the filter if necessary.
- Connect your spark plug wire and then check it with a tester. Clean and reset the gap. Replace if necessary.
- Inspect the air filter for any debris or dirt. Clean and replace if necessary.
3. Seeing your engine smoking can be a scary thing. Try these two steps before contacting a professional for more intense maintenance:
- You may have overfilled the engine oil. Check the oil level.
- Your engine might have lost its crankcase vacuum. This can be caused by a broken or improperly seated dipstick. If so, replace the defective part. Your engine breather may also be defective, which means you need to replace the engine breather.
