rocker shaft pivoted in the end frames of the roller. The rocker shaft is turned by a threaded rod and the frame thus raised or lowered to alter the working depth of the teeth.
DISC HARROW CONTROL. A vertical lever is pivoted on the harrow tongue here and its lower end linked to the inner ends of the gangs. At each end of this lever is a rod connecting with a notched cam on the sliding draft head.
