Question about Stewi Ground foundation

A short instruction is supplied with the ground socket on how to mount it correctly.
Make a hole at least the size of the perforated disc. Choose the depth of the hole so that at the end the attachment still looks over the edge of the lawn. This is important because when mowing the lawn you can only quickly remove the insertion sleeve and drive over it with the lawn mower. Now drive the pipe straight into the middle of the hole with a piece of wood. Then mount the hole ring (screw it in). Cover with soil and you're done.
