Why Hedge Trimmer Won T Cut

Dull Blades

The most common reason for a hedge trimmer not to cut is dull blades. When the blades are dull, they cannot penetrate the branches of the hedge and will simply push them aside. This can cause the hedge to become overgrown and untidy.

Dirty Blades

Dirty blades can also cause a hedge trimmer to not cut properly. When the blades are dirty, they cannot make proper contact with the branches of the hedge and will simply push them aside. This can also cause the hedge to become overgrown and untidy.

Misaligned Blades

If the blades of a hedge trimmer are misaligned, they will not be able to cut properly. This is because the blades will not be able to make proper contact with each other and will simply push the branches of the hedge aside.

Incorrect Oil Level

If the oil level in a hedge trimmer is too low, the blades will not be able to move smoothly and will not be able to cut properly. This is because the oil lubricates the blades and helps them to move smoothly.

Clogged Air Filter

A clogged air filter can also cause a hedge trimmer to not cut properly. This is because the air filter prevents dust and debris from entering the engine. If the air filter is clogged, the engine will not be able to get enough air and will not be able to run properly. This can cause the blades to stop cutting.
