Certain embodiments of the disclosure include planers with side plates which may be adjusted independently or simultaneously. In a preferred embodiment of the present invention, a planer with adjustable side plates is comprised of a planer housing enclosing a grinding drum with grinding tools to be moved over a surface to be ground in a direction of travel and a pair of side plates are arranged substantially parallel to the direction of travel and mounted substantially adjacent the housing. The side plates are mechanically linked to the housing and are hydraulically controlled to be adjustably raised and lowered relative to the housing.
