Abstract
Disclosed embodiments include implements with a linkage and suspension configured to provide downward pressure on tool to allow it to maintain a desired level of contact with a work surface. An adjustable biasing member such as an air bag provides upward pressure on the linkage to reduce downward pressure on the work surface from the tool. Shock absorbers can also be included to hold the linkage in place and limit bouncing of the tool when it is being transported.
