Abstract: A user assistance apparatus and system is disclosed. The apparatus and system may include a base and a platform rotatably positionable about the base. A lift assist chair may be disposed upon the platform, and handrails may be attached to the platform such that the handrails rotate with the platform. The handrails extend from the platform to define an entry, and the handrails are configured to assist a user as the user passes between the entry and the lift assist chair. Fixtures may be disposed in a generally curved arrangement to cooperate with the entry as the platform is rotatably positioned about the base. Related methods of use are also disclosed.

Abstract: A self-aligning row crop spraying device includes a parallelogram-shaped device comprised of a pair of guide support members disposed parallel to each other and a pair of transverse members also parallel to each other. One of the transverse members is fixed to a structure allowing the remainder of the parallelogram-shaped device to move freely about the transverse member. A pair of guide members form a channel for receiving plants. The device allows a spray nozzle to remain aligned with a row of crops throughout the spraying process.

Abstract: A chisel cultivator for post-planting cultivation. The cultivator includes a main frame. A chisel member has one end portion coupled to the frame and a second end portion spaced from the first end portion along a longitudinal axis of the chisel member for cultivating sub-surface soil during operation of the cultivator. A heave limiter is coupled to the frame ahead of the chisel member relative to the direction of operation of the chisel cultivator. The chisel member is adjustable relative to the frame to adjust the distance of the second end portion of the chisel member from the frame. A sweep assembly is coupled to the frame behind the chisel member relative to the direction of operation of the chisel cultivator. The sweep assembly includes wings which extend outwardly of a centerline extending in the direction of operation of the chisel cultivator in a plane substantially orthogonal to the longitudinal axis of the chisel member.

Abstract: An apparatus for controlling the horizontal and vertical orientation of a boom assembly. An elongated frame assembly adapted to be mounted to a vehicle has a cam plate mounted to and moveable therealong. Hydraulic drive means controls the movement of the cam plate between fully extended, intermediate, and fully retracted positions. A hinge plate assembly is rotatably mounted to the frame assembly and an elongated boom, such as an agricultural spray boom, is pivotably mounted to the hinge plate so that the boom is vertically adjustable relative to the ground.

Abstract: Soil conditioning apparatus having a main frame, and means coupled to the main frame for cutting and loosening compacted soil to prepare a seed bed and rooting environment, including a subsoiler coupled to the main frame and angled to be pulled downwardly into the earth below the surface to prepare a better rooting environment and seed bed and to increase water infiltration. A slot filler wheel is coupled to the main frame for filling voids in the soil left by the forward motion of the subsoiler therethrough; the slot filler wheel is mounted adjacent to and laterally spaced from the subsoiler so that a portion of the slot filler wheel may extend forwardly of the trailing face of the subsoiler. Also, the slot filler wheel may be mounted to lie in a plane of rotation which extends downwardly toward the subsoiler and inwardly toward the slot formed behind the subsoiler.

Abstract: A post directed crop spraying apparatus and related method, comprises a pair of opposed substantially vertically extending hood members coupled to a main mounting means. Spray nozzle means are coupled to the main mounting means and disposed between the hood members for spraying liquid material toward the ground between and under the hood members to cross row centers at the base of plants being sprayed. Knockdown bar means are coupled to the main mounting means and extend substantially transversely between the hood members for contacting and for pushing down on weeds during operation of the apparatus. The knockdown bar means are located sufficiently close to the nozzle means to permit the nozzle means to spray liquid material onto the weeds from the bases to the tips thereof and to permit liquid material to be applied in a substantially uniform pattern to the soil around the plant bases.

Abstract: Soil conditioning apparatus is disclosed which has a front coulter assembly, preferably with a fluted coulter, for preparing a narrow path wider than the following subsoiler shank by cutting trash and breaking and slitting the topsoil. Following the front coulter assembly is the subsoiler assembly for further breaking the surface soil and breaking and shattering the "hard pan" created by years of conventional tillage. Following the subsoiler assembly is the slot filler assembly for filling the slot or crevice left by the subsoiler as it moves through the ground, a sufficient amount to prevent cave-ins or settling which would carry seeds too deep to properly germinate. Behind the slot filler wheel assembly means is the seed bed implement assembly for preparing the seed bed by pulverizing the soil and by removing trash which may have remained in the seed bed region after the above mentioned prior operations.

Abstract: In a preferred embodiment of the invention, a trailer-like multi-sectioned frame is mounted on supporting spaced-apart wheels adjustable intermittently of the height of the frame and having mounted on the various sections of the frame, functional elements including a forward rotatable cutting blade for cutting upper earth soil, a following sub-soil cutting blade aligned to follow in the upper earth cut formed by the forward cutting blade and being formable of a sub-soil groove beneath the slot, a soil-fill-in tine rotatable wheel having laterally curved and directed tine ends extending a breadth wider than the slot such that are trailed along the slot the tine ends cave-in soil to fill the sub-soil groove, a seed-bed-preparing tine wheel mounted to trail in the slot behind the soil-fill-in tine rotatable wheel, and a seed planter of conventional nature mounted to trail the seed-bed-preparing tine wheel to plant within prepared soil along the slot, the tine elements of the seed-bed-preparing tine wheel being c
