The Crusher breaks blocks, and when combined with a cobble generator, it can be used to collect mass amounts of cobble. To use it, place a sign onto a piston with the text [Crush] on the second line. Every time the piston pushes the block in front of it, the piston will mine the block instead.
You can only crush blocks so quickly; if you do it too quickly, you'll find that the piston pushes the blocks instead.
If you setup an automated cobble generator farm, please be mindful of other players and keep the rate low. If you are collecting items in a chest, use a comparator to pause the crusher when the chest is full.
