Question 2

Why does my ALPINA AL5 51 SAQ lawn mower not eject grass laterally?

Accepted Answer

If your ALPINA AL5 51 SAQ mower does not eject grass to the side, here are the checks to perform:

1. Check the lateral ejection configuration

The ALPINA AL5 51 SAQ has four operating modes (collection, rear ejection, lateral ejection, and mulching). Make sure the lateral ejection mode is correctly selected according to your setup. The lateral ejection deflector is an optional part - check that your model is equipped with it.

2. Clean the ejection channel

Grass clippings, moisture, or debris can block the side outlet. After ensuring the blade is stopped, inspect and clean the ejection channel on the side of the metal housing.
