  The clutch of your Nortrac Tractor might be slipping because the clutch plate and pressure plate are dirty or greasy. Clean them with solvent and identify the cause to prevent recurrence. Alternatively, the clutch plate could be excessively worn or burnt, in which case you should replace it. A weak Belleville spring can also cause slippage, requiring replacement. Also, check if the free play of the pedal is too small or nonexistent; readjust it to the correct specifications. Lastly, deformed clutch fingers can lead to slippage, necessitating their replacement.

  If you are hearing noise or impact sounds from the gearbox of your Nortrac Tractor, it could be due to excessively worn gears or chipped tooth surfaces, which would mean you need to replace the gear. It could also be caused by a badly worn or damaged bearing, which also needs replacement. Finally, insufficient lubricating oil or oil that doesn't meet specifications can cause these noises. Refill or replace the lube oil.

  James PerryAug 26, 2025
  If your Nortrac Tractor pulls to one side when braking, it could be due to unequal free play in the left and right brake pedals; adjust them so they are the same. Another possibility is that the brake shoes on one side are damaged or worn unevenly, requiring replacement. Also, check the air pressure of the rear tires, and inflate them according to specifications if they are not the same.

Why is it difficult to put my Nortrac 40XT into gear?
- M
  Matthew ThomasAug 27, 2025
  If it's difficult or impossible to put your Nortrac Tractor into gear, it could be because the clutch has not disengaged completely; troubleshoot according to the clutch type. Another reason may be that the gearshift interlocking rod is too long, and you should shorten it. Also, the shift lever fork might be severely worn, requiring replacement. Finally, the end face of the engagement sleeve or the end face of the gear could be worn or broken, necessitating replacement or repair.

Why does the gearshift on my Nortrac 40XT disengage automatically?
- D
  Dana HarrisonAug 30, 2025
  If the gearshift on your Nortrac Tractor disengages automatically, it could be because the gearshift interlocking rod is too short; lengthen it. Another cause could be a severely worn locating slot of the shifting fork shaft, requiring replacement of the shift fork. Insufficient spring pressure of the interlocking latch can also cause this; adjust or replace the interlocking pin spring. Additionally, a worn bearing on the gear shaft, causing the shaft to tilt, may be the issue, and the bearing should be replaced. Lastly, the spline of the tooth holder might be worn, necessitating replacement of the tooth holder.

Why does my Nortrac 40XT Tractor shake when starting?
- S
  Sandra WardSep 1, 2025
  If your Nortrac Tractor shakes when starting, it could be due to several reasons. The heads of the three clutch fingers might not be in the same plane, requiring adjustments. Grease on the clutch plate and clutch fingers can also cause shaking; clean them with solvent. Warped clutch fingers can also be a cause, and they would need replacement. Finally, a loose fastening screw for the flywheel and clutch can cause shaking; stop the tractor immediately and repair the fault.

- C
  Caroline HoweSep 4, 2025
  If the clutch on your Nortrac Tractor doesn't disengage completely and you hear noise when it is engaged, it might be because the free play of the pedal is too large and the working play is too small; adjust the free play of the pedal according to the specifications. Another cause could be excessively warped clutch fingers, requiring replacement. Also, the heads of the three clutch fingers may not be in the same plane; adjust them as needed.

Why is there increased noise in the central drive of my Nortrac Tractor?
- S
  sandrahardinSep 6, 2025
  If you notice increased noise in the central drive of your Nortrac Tractor, it could be due to several factors. The bearing play of the small conical gear might be too large, requiring adjustment. Abnormal gear engagement can also cause this issue; readjust as necessary. Additionally, the bearing of the conical gear pair or the gear pair itself could be damaged, necessitating replacement. A worn or locked differential shaft can also be a cause; replace the differential gear shaft. Furthermore, worn planetary gears or gaskets can contribute to the noise, requiring their replacement. Lastly, a worn or damaged differential bearing can be the source of the noise, and it should be replaced.
