A mechanism for adjusting the height of a frame of an agricultural implement relative to a groundsurface is described. A parallelogram frame is provided which includes a frame mounted member and a wheel mounting member parallel to the frame mounted member. The frame mounted member is secured in substantially vertical orientation to an end of a transverse support member of the frame of the agricultural implement. A stub axle is secured substantially perpendicularly to a face of the wheel mounting member remote from the transverse support member with a ground engaging wheel rotatably mounted on the stub axle. An expandable jack is mounted to the top of the transverse support member. Upon expansion of the jack a force is exerted upon an upper connecting member causing the parallelogram frame to pivot until a first end of the upper connecting member to which the end of the transverse support member is attached is raised relative to a second end of upper connecting member. Upon contraction of the jack a force is exerted upon the upper connecting member causing the parallelogram frame to pivot until the first end of upper connecting member to which the end of the transverse support member is attached is lowered relative to the second end of upper connecting member.
