Abstract
An agricultural implement is equipped with a plurality of earthworking tools spaced from one another in the fore and aft direction. One of the tools is adjustable between working and nonworking positions on a main frame by a hydraulic actuator connected to the main frame by a resiliently cushioned support which includes a spring loaded link. The one tool includes a coulter gang supported on a subframe by a pair of U-shaped springs. The deflection of the U-shaped springs and the spring loaded link allows the coulter gang to pass over relatively large boulders or the like without raising the implement frame to a significant extent and without causing the relief valve in the actuator hydraulic system to open.
