Why is my Major 4200 Farm Equipment mower leaving a streak of uncut grass?
- N
  Nancy BarrettAug 16, 2025
  There are several reasons why your Major Farm Equipment might be leaving streaks. The blades could be dull or bent, requiring replacement. The carrier RPM might be too low, so you should use the correct PTO speed. If the field conditions are too wet, stop operation until it dries. The ground speed might be too fast, reduce it by shifting to a lower gear. If grass is down from previous weather conditions, mow in only one direction. There might be a build-up of materials under the mower, so clean it. Finally, the blades might be mounted incorrectly, so ensure the cutting edge faces the correct rotation.

  If your Major Farm Equipment's gearbox is overheating, first check the lubricant level and fill it to the proper level if it's low. If the lubricant is the improper type, replace it with the correct one. Also, remove any excessive grass or debris buildup around the gearbox and lower the RPM rate.

Why is my Major 4200 mower discharging material unevenly?
- M
  michael26Aug 26, 2025
  Uneven discharge from your Major Farm Equipment mower can occur if the material is too high or there is too much of it. Reduce ground speed while maintaining 540rpm at the tractor PTO, or make two passes over the material, raising the mower for the first pass and lowering it to the desired height for the second, cutting at a 90-degree angle to the first pass. Also, if the grass is wet, allow it to dry before mowing, slow the tractor's ground speed while keeping the engine running at full PTO rpm, and cutting lower may also help.

Why is my Major Farm Equipment machine so noisy?
- I
  Ivan CarneyAug 28, 2025
  A noisy Major Farm Equipment machine could be due to several reasons. A worn bearing could be the culprit, so replace the bearings. Check the oil level in the gearbox and add oil if it's low. Ensure all bolts are fully tightened, as loose parts can cause noise. Verify the PTO RPM rate and adjust as necessary. Replace any bent or missing blades. Check that the PTO shafts are aligned correctly. Also check output shaft on gearboxes are not bent and driveline between gearboxes is aligned.

What to do if my Major Farm Equipment blade is scalping the ground?
- T
  Tammy WalkerAug 31, 2025
  If your Major Farm Equipment blade is scalping the ground, it might be set too low, so raise the mower and reset the wheels. If the field is ridged, try cutting at a different angle. Also, if the field is too wet, stop and wait until it has dried.

Why are the blades on my Major 4200 wearing too fast?
- E
  Emily LawrenceSep 3, 2025
  Blades on your Major Farm Equipment might wear too fast if you are cutting in sandy or rocky conditions. In these cases, increase the cutting height. Also, ensure that the blades are not hitting the ground and increase the cutting height if they are.

What to do if my Major 4200 gearbox is leaking?
- J
  Julie JonesSep 6, 2025
  If your Major Farm Equipment gearbox is leaking, the oil seal may be damaged, installed incorrectly, or not sealing in the housing, in which case you should replace the seal and use a sealant on the outside diameter of the seal. A bent or rough shaft in the oil seal area may also cause a leak, so replace or repair the shaft. The oil level could be too high, so drain the oil to the proper level. Other potential causes include a hole in the gearbox, damaged gasket, or loose bolts, so replace the gearbox, gasket, or tighten bolts as necessary.

Why is my Major Farm Equipment mower vibrating excessively?
- K
  kevin10Sep 12, 2025
  Excessive vibration in your Major Farm Equipment mower can be caused by several factors. Check the gearbox bolts and tighten them if they are loose. Also, check for loose nuts on the blades and tighten them. A broken blade can also cause vibration, so replace the blades in a set. Avoid mixing new blades or bolts with worn ones; replace them in sets. Finally, ensure the drivelines are phased correctly, with implement and tractor yokes in line, and replace if necessary.

Why does my Major 4200 Farm Equipment mower require excessive power?
- L
  Lisa ParrishSep 12, 2025
  Your Major Farm Equipment mower might require excessive power if you are advancing into the grass too rapidly, so reduce your forward travel speed. If the mower is hitting the ground, raise it and reset the wheels. Worn or dull blades can also cause this issue, so sharpen or replace the blades. Finally, ensure that your tractor is large enough for the mower, and use a larger horsepower tractor if necessary.
