How to fix occasional uncut grass blades with my Allett Lawn Mower?
- Z
  zacharywagnerAug 12, 2025
  If you notice occasional blades of uncut grass, several factors could be at play. First, ensure the engine speed isn't too slow by increasing it. Next, avoid moving too quickly by reducing your forward travel speed. Check that the height of cut isn't too high and reduce it if necessary. A poorly adjusted bottom blade may also be the culprit, so readjust it. Finally, the cutting cylinder or bottom blade may be blunt, requiring grinding or reconditioning, and the drive belt might be slipping, needing an adjustment to its tension.

What causes excessive bottom blade wear on my Allett C 34 Lawn Mower, and how can I prevent it?
- S
  Steven MannAug 16, 2025
  Excessive bottom blade wear can occur due to several reasons. The bottom blade may be in heavy ground contact, in which case you should increase the height of cut. A blunt cutting edge requires grinding or reconditioning. Heavy contact between the cylinder and bottom blade means you should readjust the bottom blade to cylinder clearance. Also, excessively abrasive ground conditions may be the cause, and you should increase the height of cut.

What to do if my Allett Lawn Mower is causing tram lining in the grass?
- S
  Stephanie GomezAug 25, 2025
  Tram lining of grass in the direction of forward travel can be caused by a few things. The bottom blade might be in ground contact, so increase the height of cut. It could also be due to poor cylinder to bottom blade adjustment, so readjust the bottom blade. Lastly, worn cylinder bearings can cause this, requiring you to replace the worn parts.

Why is my Allett Lawn Mower scalping the grass, and how can I stop it?
- M
  Melissa HinesAug 27, 2025
  Scalping of grass can occur if the height of cut is too low for the conditions, so increase the height of cut. Uneven ground conditions can also contribute; in this case, increase the height of cut and change the direction of cut.

Why does the cylinder on my Allett C 34 knock while rotating?
- R
  Richard PenaAug 31, 2025
  If the cylinder knocks while rotating, it could be due to high spots on the cutting edges, so grind or recondition the cylinder and bottom blade. Another possibility is worn cylinder bearings, which would require replacing the worn parts.

Why does my Allett C 34 Lawn Mower leave strips of uncut grass between runs?
- R
  Robert DiazSep 7, 2025
  Strips of uncut grass between adjacent runs are typically due to insufficient overlap between runs. To resolve this, increase the overlap between runs.

Why is my Allett Lawn Mower leaving ribs in the grass perpendicular to the direction of travel?
- D
  David MatthewsSep 12, 2025
  Ribbing of grass perpendicular to your direction of travel can happen if the cylinder speed is too slow relative to your forward travel speed, so increase the engine speed. Alternatively, you might be moving too fast, so reduce your forward travel speed.
