Abstract: A packing pressure adjustment assembly for a ground opener unit of an agricultural implement includes a spring interconnected between a rotatable pressure adjustment arm and a trailing arm to which a packer wheel is rotatably mounted. The pressure adjustment arm is centered about an axle of the ground opener unit and is movable between a set of mounting positions that are defined by a set of teeth spaced and arced from one another along a frame portion of the ground opener unit. As the pressure adjustment arm is rotated, the amount of force exerted by the spring on the trailing arm is varied. The packing pressure adjustment assembly is relatively compact and is useful in providing high packing forces, such as a packing force in excess of 100 lbs.

Abstract: A precision hoe opener assembly is provided with improved accuracy of seeding as well as improved control over the opener and packer wheel assemblies. The opener assembly includes a hydraulically-driven parallel linkage assembly, a lost motion linkage, a hoe opener, and a packer wheel. The design provides improved seeding accuracy, by adjusting assembly components to and compensating for changes in terrain elevation.

Abstract: A marker assembly includes a first linkage section interconnected to a second linkage section by a pivoting joint. The pivoting joint also includes a spring linkage that limits momentum in the second linkage section before a marking disc carried by the second linkage section engages the ground. The spring linkage may be comprised of a spring that is retained by a pair of washers within a housing or canister. A linkage rod passes through the canister and has a set of nuts that are sized to catch the washers. Thus, if the spring linkage is compressed or extended, the catch nuts press up against the washers thereby compressing the spring. By compressing the spring, a force is applied in the opposite direction as the momentum in the marker assembly, which reduces the collective momentum in the marker assembly during deployment.

Abstract: A low till agricultural implement has a frame with a hitch for attachment to a tractor. A straight coulter composed of an array of parallel circular blades is mounted to the front of the frame, and is followed by a spiral reel assembly and a spike tooth harrow assembly. The circular blades are mounted perpendicular to rotating shafts, and slice through field residue and soil with minimal side movement of material. The blades of the following reel then make cuts nearly perpendicular to those made by the circular blades. A trailing level bar follows the spiral reel. The implement aids in drying the soil surface layer, and, by cutting up residue and even spreading, the implement helps to warm up the soil.

Abstract: An agricultural implement has a main frame and laterally positioned carrier frames pivoted to the sides of the main frame. The main frame extends forward to a coupling point for connection to a prime mover. The rear of the main frame mounts a hydraulic piston assembly that is interconnected to each carrier frame to elevate same into an upward tilted transport position. Each frame and carrier frame supports a frame portion having a respective group of rotatable soil working members positioned in a row to work a broad path during working operation. Connecting members on the carrier frames are connected to the central frame portion to raise same when the carrier frames are in their tilted transport positions. Latches supported on the main frame secure beams of the carrier frames in their tilted positions until release.

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.
