Abstract: An aerator includes a frame supported on a pair of forward drive wheels and a pair of rearward caster wheels. An aerator head is mounted on a pivot frame on the forward end of the aerator frame, pivotable to move the aerator head from a disengaged position above the ground, downwardly to an engaged position wherein tines on the aerator head work the soil. The pivot frame includes a forwardly projecting arm upon which the aerator head is mounted, and a rearwardly projecting arm upon which the forward wheels of the frame are mounted, such that movement of the pivot frame will engage either the forward wheels of the frame or the aerator head with the ground. The aerator head is mounted forwardly of the forward end of the frame such that the tines on the aerator head form the forward most part of the aerator.

Abstract: Various earthworking machines make use of an oscillatory blade, such as the herein referred to sod cutter. Instead of employing two handles, one of which raises and lowers the blade and the other of which handles, when tightened, maintains the blade at a selected depth, only a single handle is employed. When the handle is manually moved forwardly, the blade is lowered and when moved rearwardly the blade is raised, but when the single handle is moved to the left the blade is locked at the depth that has been determined by the forward movement of the handle, this handle movement to the left camming a shiftable gear rack into engagement with a fixed gear rack to maintain the adjusted blade depth. Handle movement to the right allows a coil spring to disengage the racks. A stop, when appropriately set, enables the selected depth to be re-established after each raising of the blade whenever no change in blade depth is needed.

Abstract: The application discloses a multi-row plow adapted to be towed behind a small walking tractor. The plow comprises a draft frame having a pivotal attachment to the tractor and a tool frame. At the rear of the tool frame there is a ground engaging wheel. Apparatus is provided to change the elevation of the wheel relative to the draft frame, thereby to adjust the elevation of the rear end of the draft frame. Linkage causes the forward end of the tool frame to be raised when the rear end of the draft frame is raised, and vice versa. The foregoing provides a simple and labor-saving way of removing the tool from the ground at the end of the row for turning the apparatus around.

Abstract: Apparatus of a dual wheel, engine driven garden plow for breaking up soil, then distributing the soil in rows and plowing out between the rows during the growth of a crop. Such apparatus includes an engine powered tractor, dual wheel front frame construction and a counter weight stabilizer bar in the rear for permitting riding of the apparatus. A lever system provides the adjustment structure for the plow itself.

Abstract: A self propelled apparatus providing a cultivator, planter units and fertilizer tanks. A traction wheel assembly composed of a plurality of wheels adapted to propel the entire apparatus forwardly by pushing. The plurality of traction wheels being mounted from a traction wheel assembly frame and the traction wheel assembly frame being formed in two sections which are pivoted together at the mid-point thereof. The plurality of traction wheels being arranged in pairs and adjacent pairs of traction wheels being connected together for co-action therebetween. Separate means are provided for driving the traction wheels and such wheels being balanced and mounted from the pivotal frame will impart substantially no compacting forces to the treated soil. The apparatus includes structure and mechanism whereby the sections of the traction wheel assembly frame may be separated to thereby reduce the width of the traction wheel assembly and traction wheel assembly frame for road transport.

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.
