Abstract: A self-propelled disk harrow apparatus having four gangs of disc members attached thereto which are rotated to propel the disk harrow and to thereby till the soil. Wheels are provided for allowing the disk harrow to travel on public roads and to aid in propelling the disk harrow. When the disc members extend too far into the soil or otherwise become ineffective in propelling the disk harrow, for example when in wet or sandy soil, the weight of the disk harrow transfers to the wheels and the wheels tend to primarily propel the disk harrow. A hydraulicly controlled pitch control is provided for controlling how deeply the discs extend into the ground. An automatic coupling structure is also provided for allowing each gang of discs to be folded for extending the effective length thereof and still providing power to all of the discs on each gang.

Abstract: A frame carries two transverse digger shafts each having a plurality of diggers mounted thereon in spaced apart relationship such that the diggers form independent furrows. The frame is supported on wheels on a single axis between the two digger shafts and it tiltable on this axis substantially independently of the three point hitch by virtue of a pair of pivoted connections between the hitch and the frame. A longitudinal tilt arm extends from an elevated position over the frame and is connected near its forward end by a resilient member to the hitch or to a selected attachment point on a rigid telescoping member also extending between the tilt arm and hitch. The tilt of the frame is also biased by placement of the wheel frame axis slightly to the rear of the frame's center of gravity. The digger shafts are connected to the drive for opposite relative rotation with the rear shaft rotating rearwardly whereby its diggers apply a retarding force to the frame and stabilize the frame on the frame wheel axis.

Abstract: A ground working implement is provided wherein a motor driven auger is positioned beneath and partially enclosed by a truncated V-shaped plowshare. The auger contributes to the forward movement of the implement. The space between the auger and the plowshare causes clods of soil to be uniformly broken. Mechanical features are provided, in association with a frame structure, to guide the implement, to adjust the height of the auger, and to control the operation of a motor or engine.

Abstract: A powered machine for moving along the ground surface and producing a succession of holes therein to aerate the soil. The present aerator includes a pair of ground-penetrating members that are moved alternately to engage, penetrate, and disengage the ground's surface. They are moved both vertically and horizontally to "walk" the aerator in a forward path. Each ground-penetrating member is moved through an elliptical circuit in a vertical plane parallel with the forward path. The penetrating members are retained in substantially upright orientation throughout the complete circuit. They are tipped slightly as they engage and leave engagement with the ground to form a uniform upwardly open hole as the aerator is propelled forwardly.

Abstract: A self powered, handlebar operated, earth cultivating machine having a worm gear engine drive and a transversely extending, soil engaging rotating tine wheel is provided with a pair of ground engaging traction wheels spaced therebehind and a sprocket and chair drive train coupled between the tine wheel and each of the traction wheels for driving the latter to selectively propel or brake the machine in accordance with the traction created by the tine wheel with the tilled soil. The worm gear and chain drive train cooperate to lock the traction wheels into a constant driving relationship with the tine wheel in a manner to automatically compensate both for excessive forward thrust produced by the latter in hard soil and for insufficient thrust created thereby in soft soil whereby to eliminate lurching and stalling of the machine and achieve especially smooth, consistent tilling operation.

Abstract: A self propelled disk harrow having four gangs of disc members attached thereto which are rotated to propel the disk harrow and to thereby till the soil.
