Abstract: This invention relates to harrows, such harrows being of the kind comprising a frame portion that is movable over the ground and that is provided with a plurality of soil working members or rotors arranged to turn about corresponding upwardly extending axes, the frame portion being sustained from the ground during the use of the harrow by a rotary supporting member.

Abstract: A power cultivator apparatus being a self propelled device having structure for supporting a tool member thereon for earthworking operations in a limited space or area requirement such as cultivating a single row at a time. More particularly, the power cultivator apparatus provides a power assembly mounted on a support and guide assembly; a tool member connected to the support and guide assembly for earthworking purposes; and a control assembly having foot actuated members operable to 1) raise and lower the tool member; 2) operate a transmission assembly; and 3) raise and lower front forward lateral support wheel assemblies for ease of operation.

Abstract: 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.
