<p>A cultivator for pedestrian operation which has rotatable soil working members mounted on upright shafts and a rear supporting member with driving means that both rotates the soil working members as well as the rear supporting member to operate and propel the implement. A forward supporting member is pivoted to the frame and can be adjusted about a horizontal axis to regulate soil working depths and for transport. Preferably, the rear and forward supporting members are each rotatable and pivoted to the frame to turn about a common axis. These members are articulated by arms to an upright spindle that can be turned to simultaneously move the supporting members vertically. The rear supporting member has elongated rods with bends intermediate their ends to form a soil smoothing member.</p> |
