Why is my Spearhead TWIGA 500 Tractor Accessories gearbox overheating?
- C
  Cindy BeltranAug 17, 2025
  If your Spearhead Tractor Accessories gearbox is overheating, several factors could be the cause. It may be due to an incorrect oil level, so check the oil level. The oil grade might also be incorrect, so verify the oil grade. Overloading the implement or using the wrong PTO speed can also lead to overheating. In these cases, reduce forward speed or ensure the tractor PTO speed matches the implement's requirements.

  Steven ReyesAug 20, 2025
  Excessive belt wear on your Spearhead Tractor Accessories can stem from a few issues. Start by checking the condition of the belt and pulley; replace them if necessary. Ensure proper pulley alignment. Incorrect belt tension can also cause wear, so tension the belts to the specified level. Finally, overloading the implement can contribute to this problem; reduce forward speed or increase the height of cut.

  Maria BaldwinAug 22, 2025
  If your Spearhead Tractor Accessories oil tank is overheating, several factors could be the cause. It may be due to an incorrect oil level, so fill the tank to the correct level. The oil grade might also be incorrect, so drain and refill the tank with the correct grade oil. If the PTO speed is too fast, ensure the tractor's PTO speed matches the implement. High ambient temperature or an overloaded machine can also cause overheating. Try reducing the work rate or installing an oil cooler; reduce forward speed or increase the height of cut.

Why does my Spearhead TWIGA 500 Tractor Accessories break-back operate frequently?
- G
  George MeyerAug 26, 2025
  Frequent break-back operation in your Spearhead Tractor Accessories can occur due to several reasons. The machine might be overloaded, so reduce forward speed or increase the height of cut. Using the machine on an excessive incline can also trigger this; switch off auto reset. If the weight of the machine is being carried upon the rear roller, use Autopilot or head float. Also, ensure the machine is set vertical by shortening the top link.

What causes P.T.O. wear U.J. failure in Spearhead TWIGA 500?
- G
  Garrett BaileyAug 27, 2025
  P.T.O. wear or U.J. failure in your Spearhead Tractor Accessories can be attributed to a few reasons. If the working angle is too great, reduce the offset of implements. An incorrect shaft length, such as the shaft bottoming out, can also cause this; resize the PTO shaft as recommended. Lack of maintenance is another factor; grease the PTO shaft as recommended.

What to do if Spearhead TWIGA 500 Tractor Accessories hydraulics are not responding?
- M
  Misty WilliamsAug 30, 2025
  If the hydraulics on your Spearhead Tractor Accessories are not responding, start by checking the oil level and fill it to the correct level if it's low. A blocked oil pump suction filter can also cause this issue, so replace the filter element. Look for any oil leaks in the pressure line. Finally, ensure the pump is rotating, as a broken driveline could be the problem.

What causes rotor vibration in Spearhead TWIGA 500?
- M
  martinkristiSep 2, 2025
  Rotor vibration in your Spearhead Tractor Accessories can arise from several causes. Check for broken or missing flails and replace them. Worn or damaged bearings can also lead to vibration, so replace them. A bent rotor needs to be re-balanced or replaced. The build-up of debris and incorrect speed can also cause vibration; remove debris and check rotor R.P.M.

How to improve cut quality of Spearhead Tractor Accessories?
- C
  crobinsonSep 4, 2025
  Several factors can affect the cut quality of your Spearhead Tractor Accessories. Worn flails can cause a poor cut, so replace them. Check the tractor PTO speed because rotor speed/direction influences cut quality. Finally, crop condition can play a role; look for suitable conditions.

What causes rotor bearing failure in Spearhead TWIGA 500?
- T
  tylerhaleySep 7, 2025
  Rotor bearing failure in your Spearhead Tractor Accessories can occur due to several reasons. If the rotor is out of balance, see rotor vibration solutions. Wire or string in the bearing can cause failure, so remove any wire or string. Lack of maintenance is another factor; grease bearings to schedule. Water in the bearing can also lead to failure; expel water with grease.

Why is my Spearhead TWIGA 500 joystick control sluggish?
- J
  Justin SmithSep 9, 2025
  If the joystick control on your Spearhead Tractor Accessories feels sluggish, it might be due to air in the pilot lines from the joystick. To resolve this, slacken off each line of the pilot circuit individually at the spool valve while operating. When all air is expelled, retighten the line.
