23	Working aggregate, more particularly for soil cultivation	US36922073	1973-06-12	US3884310A	1975-05-20	SOUCEK JOSEF; BRAZDA ZDENEK; GRECENKO ALEXANDR
The working aggregate comprises a working unit supporting working tools and suspended on lifting arms between a front and a rear power unit for swinging movement about vertical connecting pins. The working unit can be positively deflected in relation to the power units, to assume either a transport position in which all three units are in alignment, or a working position, in which the working unit is deflected sideways relative to the power units, to assume the required working width. Driving through curves are facilitated by a positively controlled turning mechanism arranged on the rear power unit. All members are adapted for remote control from the driver''s seat on the front power unit.
24	Garden plow apparatus	US3774692D	1971-05-26	US3774692A	1973-11-27	MCDANIEL J
A horizontal U shaped frame is provided with a first horizontal transversely extending axle adjacent the curved portion of the member and supporting wheel means. A second axle parallel to the first and spaced rearward from the first is connected to the first by belt drive means. A motor supported on a platform extending between the side bars of the frame, at the rear of the wheel means, drives the second axle to drive the first axle and produce motive power. The user guides the apparatus by holding the free ends of the member legs. Plow means, pivotally secured to a third parallel axle disposed rearward of the motor and loaded by a small portion of the motor''s weight, digs into the ground and provides plowing action as the member moves forward.
25	Power plow	US3734198D	1971-01-06	US3734198A	1973-05-22	COLEMAN S
A power plow for producing a single furrow having a traction increasing drive wheel, a caster for aid in steering and varying furrow depth and a support stand for machine storage.
26	Garden tractor	US3661212D	1970-10-22	US3661212A	1972-05-09	JOHNSON FRED LEE
An engine and transmission assembly, within a traction wheel, is suspended by hollow trunnions on which the traction wheel is journalled. An inverted U-shaped yoke, fixed to the trunnions, straddles the wheel and combined draft, stabilizing and steering means connect the yoke to an implement frame for relative tilting about a fore-and-aft axis and for steering the wheel relative to the frame. A reaction member is universally pivoted to the top of the yoke and is connected to the implement frame. Articulated controls for the engine and transmission extend from the implement frame through the hollow trunnions.
