What to do if the starter motor doesn't work on my Yanmar Farm Equipment?
- W
  William McdanielAug 15, 2025
  If the starter motor isn't working when you turn the key, make sure the brake pedal is fully depressed. Also, ensure the threshing clutch lever is in the 'OFF' position. Check the battery; it may be dead and need recharging, or the terminals might be loose or corroded, requiring cleaning and tightening with antirust oil applied. Finally, inspect the fuse and replace it if it's blown.

Why does the starter motor rotate but the Yanmar AW70V engine won't start?
- A
  Andrew WheelerAug 18, 2025
  If the starter motor rotates but the engine doesn't start, check if the fuel pump is working (replace the fuel pump if it’s faulty). Ensure there's fuel in the tank and that the fuel pipe isn't damaged (replace if damaged). Exhaust any air mixed in the fuel. Confirm the range shift lever is in the 'N' (neutral) position. Also, check for water in the fuel tank, and drain it from the fuel filter or water separator. Finally, inspect for blockages in the pipe due to contamination; clean the fuel tank and pipe if necessary.

How to fix crops not being threshed completely by Yanmar AW70V?
- J
  Jessica WalshAug 22, 2025
  If crops aren't being threshed completely, check if the revolving speed of the threshing rotor is too low. Adjust the accelerator lever to raise the engine speed to the 'Green zone'. Also, ensure the chaff discharge adjust lever is not in the 'Open' position; put it to the 'Close' side. If there is insufficient feed of crops, raise the harvesting speed slightly. In case crops are conveyed unevenly, speed up harvesting, and lower the reel backward if it is too near the front.

Why is there an abnormal sound in the threshing section of my Yanmar AW70V Farm Equipment, or why has efficiency decreased?
- M
  Maureen DavisAug 25, 2025
  If you notice an abnormal sound or decreased efficiency in the threshing section, it could be due to several reasons. If crops are wet from dew, wait until they dry before harvesting. Check the engine tachometer and adjust the accelerator lever to raise the engine speed to the 'Green zone' if the rotor speed is too low. Reduce your operating speed if it's too high. If the moisture content of rice is high, put the chaff discharge adjust lever to 'Open'. Also, identify and remove the cause of any uneven conveying of crops.

How to reduce heavy loss in the reaping section of Yanmar AW70V Farm Equipment?
- K
  karen85Aug 27, 2025
  To reduce heavy loss in the reaping section, lower the reel if crops are accumulating in front of the cutter blades, ensuring smooth flow to the platform auger. Adjust the header height; it shouldn't be too high, and harvested crops should be appropriately long for even conveyance to the platform auger. If reverse harvesting, adjust the reel to a proper height to prevent it from pressing the crops.

What causes grain splashing in Yanmar AW70V Farm Equipment and how to fix it?
- O
  Olivia WalkerAug 30, 2025
  Grain splashing can occur if the chaff discharge adjust lever is in the 'Open' position; move it to the 'Close' side. If the engine speed is too high, check the engine tachometer and adjust the accelerator lever to raise the engine speed to the 'Green zone'. Also, ensure the angle of the chaff sieve of the swing separator is appropriately adjusted according to the crop condition and that the air volume of the fan is correctly adjusted.

What to do if crops are not conveyed in Yanmar Farm Equipment?
- J
  Joanna TerrellSep 3, 2025
  If crops aren't being conveyed, inspect the cutter blades and conveying chain for obstructions like grass, straw, mud, stone, or other foreign materials, and remove them. Also, check if the header drive belt is loosened and adjust it if necessary.

Why is Yanmar AW70V Farm Equipment pulling out rice roots and how to prevent it?
- A
  Alan HobbsSep 5, 2025
  Rice roots being pulled out can occur if the crop divider cuts into the root of the crop; adjust the front end of the reel. If harvesting too rapidly, reduce the speed to suit the crop and field conditions. Also, check and adjust the gap between the cutter blades.

How to fix a stuck reel on Yanmar AW70V?
- M
  michaeldrakeSep 8, 2025
  If the reel is stuck, it might be due to the angle of the reel tines being too small; adjust them properly. Alternatively, the reel might be too low; adjust it to a proper height.
