How to fix Major Farm Equipment that leaves uncut grass?
- C
  Catherine MeltonAug 17, 2025
  If your Major Farm Equipment leaves a streak of uncut or partially cut grass, several factors could be responsible. The blades might be dull or bent, requiring replacement. Ensure you're using the correct PTO speed. If field conditions are too wet, stop operation until it dries out. Reduce ground speed by shifting to a lower gear. If grass is down from previous weather, mow in only one direction. Clean the mower to remove any material build-up. Finally, ensure the blades are mounted correctly with the cutting edge facing the correct rotation.

Why does my Major Farm Equipment discharge material unevenly?
- B
  Brandon HudsonAug 20, 2025
  If the Major Farm Equipment discharges material unevenly, leaving bunches along the swath, it could be due to a couple of reasons. If the material is too high or there's too much of it, reduce your ground speed while maintaining 540rpm at the tractor PTO. Alternatively, 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 and slow down the tractor's ground speed, keeping the engine running at full PTO rpm.

  If your Major Farm Equipment's gearbox is overheating, there are a couple of things to check. First, make sure the lubricant level is adequate and that you're using the correct type of lubricant; replenish or replace as needed. Also, excessive grass or debris build-up around the gearbox can cause overheating, so remove any accumulated material from the machine.

Why is my Major Farm Equipment vibrating excessively?
- R
  Richard CollinsAug 26, 2025
  Excessive vibration in your Major Farm Equipment can stem from several issues. Start by checking the gearbox bolts and blade nuts, tightening them if they're loose. Inspect the blades for any breaks and replace them as a set if needed. Ensure that new blades or bolts are not mixed with worn ones, replacing them in sets. Finally, verify that the drivelines are phased correctly, aligning the implement and tractor yokes; if necessary, phase the driveline or replace it.

Why is the gearbox leaking on my Major Farm Equipment?
- C
  Curtis LucasAug 28, 2025
  Several factors can cause a Major Farm Equipment gearbox to leak. It could be due to a damaged oil seal, in which case you should replace it. A bent or rough shaft in the oil seal area also requires replacement or repair. Ensure the oil seal is properly sealing in the housing, and use a sealant on the outside diameter of the seal if needed. If the oil level is too high, drain it to the proper level. In more severe cases, a hole in the gearbox necessitates replacing the entire gearbox. Damaged gaskets should be replaced, and loose bolts need tightening.

What causes blades scalping ground on Major Farm Equipment?
- C
  Courtney MercadoAug 30, 2025
  If the blades on your Major Farm Equipment are scalping the ground, it could be due to a few reasons. The mower might be set too low, so try raising it. If the field is ridged, try cutting it at a different angle. Also, if the field is too wet, stop and wait until it has dried out.

Why is my Major Farm Equipment so noisy?
- B
  brooke25Sep 2, 2025
  A noisy Major Farm Equipment machine could indicate several issues. A worn bearing may need replacement. Low oil in the gearbox requires checking the level and adding oil. Ensure the correct PTO rpm rate is set and adjust as necessary. Bent or broken rotors should be replaced. Finally, check that the PTO shafts are aligned correctly, the output shaft on the gearboxes isn't bent, and the driveline between gearboxes is aligned.

Why does my Major Farm Equipment require excessive power?
- D
  Dr. Chris BullockSep 5, 2025
  If your Major Farm Equipment seems to require excessive power, several factors could be at play. If you're advancing into the grass too rapidly, reduce your forward travel speed. If the mower is hitting the ground, raise it and reset the skids. Worn or dull blades should be sharpened or replaced. Finally, ensure that your tractor is large enough for the equipment; if not, use a larger horsepower tractor.

Why does the cutting deck on my Major Farm Equipment swing behind the tractor?
- A
  anthony41Sep 12, 2025
  If the cutting deck on your Major Farm Equipment swings behind the tractor while cutting, it could be due to a few reasons. If you're advancing into the grass too rapidly, reduce your forward speed. If you're dealing with a very heavy crop, reduce your forward speed and/or change the cutting height. Also, the pressure relief valve might be set too low, so adjust it until the cutting deck stops falling back.
