Abstract: A residue clearing apparatus for a seeding implement includes a plurality of ground driven residue wheel pairs, each movably and rotatably mounted to the seeding implement with right and left residue wheels on corresponding right and left sides of one of the shanks such that each residue wheel pair moves vertically independent of the shanks. Residue contact members connected to each residue wheel engage the ground surface adjacent to one of the shanks to rotate the residue wheel. Outer ends of the residue contact members pass forward of the shank above the furrow opener. A raising system operative to raise the residue wheel pairs to a wheel transport position.

Abstract: Provided are a deicing unit adjustment mechanism, a deicing unit, a deicing vehicle, and a deicing method. The adjustment mechanism comprises sub-adjustment unit(s) comprising a positioning wheel, a screw rod, a guide rod having one end connected with the screw rod, an upper-end cover slidably arranged at one end of the screw rod away from the guide rod, a lower-end cover fixedly arranged at one end of the screw rod close to the guide rod, a positioning wheel-adjustment spring sleeved outside the screw rod and having two ends abutting against the upper- and lower-end covers and a pressure-adjusting nut at one end of the screw rod away from the guide rod and one side of the upper end cover away from the guide rod. The positioning wheel is rotatably-arranged at other end of the guide rod, with an axis of the positioning wheel perpendicular to that of the guide rod.

Abstract: A garden implement that utilizes a hub motor assembly coupled to a frame. One or more working tools may be selectively coupled to a hub body encompassing a hub motor of the hub motor assembly. The working tools are operative to work soil in a garden or other agricultural setting. The hub motor may include a brushless DC motor driven by an electrical power source. The electrical power source may include a battery or an AC power source. Alternatively, the hub motor may be used to drive a wheel which propels the garden implement.

Abstract: An agricultural implement for towing over fields, for incorporating crop residues into soil, possessing a pair of juxtaposed, substantially parallel, spaced-apart, rotatable shafts, comprising a first forwardly-mounted shaft and a second rearwardly-mounted shaft, each mounted on a frame transversely to a direction of travel of said implement. A plurality of protruding tine members, extending substantially radially outwardly from each of said pair of shafts and longitudinally spaced along each of said pair of shafts, each tine member adapted to rotate about a longitudinal axis of a respective shaft, a tip of each of said tine members when rotating about said respective shaft creating a circular arc, are further provided. The circular arcs of the tine members on one of said pair of shafts interdigitate with a corresponding plurality of circular arcs of said tine members on said other of said pair of shafts.

Abstract: A soil cultivating machine or rotary harrow has a row of tined soil working members that are driven about upwardly extending shafts. Further soil working or cultivating members between the driven members are mounted for free rotation about axes also located in the same row which extends transverse to the direction of travel. The further members have tines or blades that are supported on respective arms that extend forwardly and are journalled on vertical shafts at the front of a frame portion. The arm of a pair of blades or a pair of freely rotatable tined members is pivotable to and fro between limit stops to avoid obstacles in or on the ground. The tined members are freely rotatable about upwardly extending axes and the bladed members are freely rotatable about horizontal axes to assist in shedding weeds and other debris.

Abstract: A soil cultivator has at least one rotor mounted for rotation about a horizontal axis and rows of rigid soil working tines are secured on the rotor to be driven through the soil in a direction opposite to the travel direction of the cultivator. The tines can be curved with their free ends oriented to the rear with respect to their direction of movement through the soil. Stationary tines can be affixed in front of the rotor so that the rotor tines are moved between the stationary tines. Two rotors can be mounted side-by-side on a common shaft or axis of rotation and the shaft journalled in side plates having edge rims. A row of rotatable disc-like supporting members is arranged zig zag on a beam and the beam has arms that are adjustably connected to the cultivator frame at the rear of the rotor. Projections on the bottoms of the members induce rotation thereof. The rotor or rotors can also be supported by an elongated roller having a helical rib.

Abstract: A harrow has rotary soil-working members in driving connection and spaced apart from one another to work non overlapping paths through the soil being cultivated. Between the rotary soil-working members, non rotary tines are positioned to work the strips remaining between the paths already worked. The non rotary tines are pivoted to the frame to move to and fro through the strips during travel. The rotary soil-working members are tined supports and the supports are elongated horizontal members to which arcuate-shaped brackets are attached. The brackets afford stops for the non rotary tines that are moving to and fro during operation so that the to and fro movements of the non rotary tines are limited.
