Why does my Major MR180 Lawn Mower leave a streak of uncut grass?
- P
  pferrellAug 17, 2025
  Streaks of uncut grass can occur for several reasons. The blades might be dull or bent, requiring replacement. The carrier RPM could be too low, so ensure you're using the correct PTO speed. If field conditions are too wet, stop mowing and wait for drier conditions. A ground speed that is too fast can also cause this, so reduce your speed by shifting to a lower gear. If the grass is down due to weather, try mowing in only one direction. Lastly, there might be a build-up of materials under the mower, so clean the mower.

Why is my Major MR180 Lawn Mower gearbox overheating?
- L
  Luis GomezAug 20, 2025
  An overheating gearbox can be caused by several factors: the lubricant level might be low, requiring you to fill it to the proper level; the lubricant type might be incorrect, so replace it with the proper lubricant; or there might be excessive trash build-up around the gearbox, which you should remove.

What to do if material discharges from Major MR180 unevenly?
- T
  Teresa BenjaminAug 22, 2025
  Uneven discharge can happen if the material is too high or there's 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, and slow down the tractor's ground speed while keeping the engine running at full PTO rpm.

Why Major MR180 Lawn Mower seems to require excessive power?
- E
  Elizabeth MorenoAug 26, 2025
  If your mower requires excessive power, it could be due to several reasons. You might be advancing into the grass too rapidly, so reduce your forward travel speed. The mower might be hitting the ground, so raise it and reset the wheels. The blades might be worn or dull, in which case you should sharpen or replace them. Finally, the tractor might not be large enough, so consider using a larger horsepower tractor.

Why does my Major MR180 have excessive vibration?
- L
  Lee BrownAug 28, 2025
  Excessive vibration can stem from several issues. Start by checking the gearbox bolts and tightening them if they're loose. Also, check for loose nuts on the blades and tighten those as well. A broken blade can cause vibration, so replace the blades as a set. Avoid mixing new blades or bolts with worn ones; replace blades or bolts in sets. Finally, ensure the drivelines are phased correctly, with implement and tractor yokes in line, and replace if necessary.

What to do if Major Lawn Mower blade is scalping ground?
- J
  Jade BlairAug 31, 2025
  If the blade is scalping the ground, it could be because the mower is set too low, so raise the mower and reset the wheels. Alternatively, if the field is ridged, try cutting it at a different angle. Also, if the field is too wet, stop mowing and wait until it has dried.

- J
  John HartSep 5, 2025
  If your mower won't cut, and it's a shear bolt drive model, the shear bolt may have sheared, requiring you to install a new one. Alternatively, the belts might have slipped and need stretching, or the belts may be broken and need replacement.

Why Major Lawn Mower blades wear too fast?
- C
  Christina ChapmanSep 8, 2025
  Blades wearing out quickly can be due to several reasons. You might be cutting in sandy or rocky conditions, so increase the cutting height. Also, blades hitting the ground can cause excessive wear, so increase the cutting height.

What to do if Major Lawn Mower PTO contacts mower front frame when raised?
- J
  Jacqueline MorenoSep 12, 2025
  If the PTO contacts the mower's front frame when raised, it's likely due to raising the mower too high or incorrect adjustment of the tractor top link. Adjust the top link or tractor lift stops according to the attachments instructions.
