In a lawn mower, the belt works as the pulley synchronizing the blade (or blades) with the mechanism. So, while the issue is about the blade engagement, see if the belt is perfectly engaged.

As mentioned above, the belts might be set too tight, so it creates a stretchy situation on blades or loose that is continuously slipping off the track. The blades may also fail when the belt is snapped or packed up as a result of over process, i.e., cutting too many leaves or grasses that pack up under the desk and push off the belt from the track.

To resolve, we suggest the following,

  1. If the belt is stretchy and tight, try loosening or replace with a longer one.
  2. If it is too loose, find a shorter belt.
  3. Avoid over processing. Better to work in short segments.
  4. If packed up with the grasses and leaves, take your time and have a clean-up.
  5. In case the belt is too old and starts losing elasticity, it is better for the machine to get a new belt.

Resolve When Lawn Mower PTO Won’t Engage

The PTO (also called Power Take Off) is a mechanism that transfers power as a secondary component with the flywheel. When the reason behind blade disengagement is PTO, you need to check the knob, whether it is faulty or just failed.

In this case, you will need a replacement with a good one. So, while purchasing, keep the model and the serial number of the lawn mower in mind. Otherwise, the dealer might end up recommending another mismatch, which may eventually not benefit the replacement at all.

Fixes for Lawn Mower Clutch Won’t Engage

Now the clutch is the closest component with your lawn mower engine and withstands the highest of the frictions. As a result, it surely faces erosion and, at some point, starts tearing.

While the material faces a loss of dimensions, it definitely will not serve as the new product. In this case, replacing the clutch would be a better idea. You can also try re-adjusting the component closer to the clutch if you have good control over the internal mechanism.

The clutch is the most expensive among the components mentioned in the table above, i.e., $200- $300. So it is better to take your lawn mower to a dealer to see the condition of the clutch, whether you need to change it or any adjustment could be applied, before making any decision yourself right?
