Welcome to the Ardupilot community! The small little mower group is only a very tiny part of a very large community of world wide users and we are just glad they let us use their platform. It is very important to learn how to search the entire Ardupilot website for information. Having a “sticky” thread at the top is a good idea we have pushed for in the past and maybe we need to try again.
Here are some of the other active mower conversations.
