An assembly for use in adjusting a pitch of a tool relative to a machine may have a link with a first end connectable to the tool and a second end connectable to the machine. The assembly may also have a bushing configured to engage a slot in at least one of the machine and the tool. An offset bore may be formed in the bushing. The assembly may also have a pin passing through the offset bore of the bushing and the link. The bushing may be reconfigurable between a plurality of discrete positions within the slot to incrementally adjust the pitch of the tool relative to the machine.
