  • Patent number: 7721815
    Abstract: A cushion standard shield system to remove and deflect residue, dirt, debris, and soil from a cushion bearing hanger, or cushion standard, portion of a disk gang type agricultural implement is provided. The cushion standard shield system includes a mounting bracket supported by a common axle which carries multiple disk blades of the disk gang. A blade assembly is mounted to an upright portion of the mounting bracket, and is positioned generally behind and above the axle, behind the cushion standard. The blade assembly includes one or more plate member with arcuate lateral edges. The radii of the arcuate lateral edges correspond closely in magnitude to the radii of the concave and convex surfaces of the disk blades. The plate members are laterally adjustable with respect to each other, whereby the width dimension of blade assembly is variable to accommodate different axial spacing widths of adjacent disk blades.

  • Patent number: 7717047
    Abstract: A friction drive for an agricultural planter has a linear actuator, which may be hydraulically or pneumatically controlled, to selectively raise or lower a drive wheel into frictional engagement with a carrying wheel. A valve network is fluidly associated with the linear actuator and allows the operator or pilot to variably define the degree of frictional engagement. This allows the operator to vary the amount of frictional engagement of the drive wheel and the carrying wheel, the output of which is used by a material dispensing system to deposited planting material onto a planting surface.

  • Patent number: 7703404
    Abstract: A seed tank arrangement is provided with improved access to seed tanks of an agricultural planter and the contents thereof, while simplifying the manufacturing of such tanks. The seed tank has a fill opening formed in the upper surface of the tank for loading and accessing seeds in the interior of the tank. Features of the tank are mirror images about a diagonal plane of the tank, which enables the same tank to be used for both the left and right sides of the planter. This is achieved by rotating the left tank 90 degrees with respect to the right tank. The design provides improved access to the interior of the tanks for filling and servicing the seed.

  • Patent number: 7669538
    Abstract: An air velocity indicator and control device is provided for use with pneumatic distribution systems used in air seeders that pneumatically discharge agricultural product to the ground, seedbed, or furrow. The air velocity indicator and control device includes a tubular housing, extending between an inlet and an outlet, and pivotally housing a deflectable plate that actuates in response to encountering an airflow entrained with agricultural product. A magnitude of deflection of the deflectable plate, corresponding to airflow velocity, can be displayed through an indicator assembly. This enables a user to identify velocity variances and differentials within the air seeder and make corrective adjustments. In some implementations, multiple air velocity indicator and control devices are ganged together with deflectable plates that pivot in unison with each other. The relative angle of fixation of the deflectable plates, upon the pivot pin, can be adjusted to permit airflow tuning as needed.

  • Patent number: 7640877
    Abstract: A branch for distributing granular material includes an inlet portion, a transition portion downstream of the inlet portion, and an outlet portion downstream of the transition portion. Each portion has a critical air flow rate that is required to cause the granular material to flow through the respective portion. The branching that occurs at the transition portion results in the critical air flow rate of the transition portion being greater than the critical air flow rate of the inlet portion, typically requiring an amount of air at least equal to the critical air flow rate of the transition portion to flow granular material through the branch. In the disclosed branch, the inlet portion is oriented relative to the outlet portion such that applying air to substantially equal the critical air flow rate of the inlet portion results in granular material being urged by gravity to move through the transition portion and into the outlet portion.

  • Patent number: 7631817
    Abstract: A lock assembly operable to secure a lift linkage associated with moving a boom assembly between a lowered, operative position and a raised, inoperative position is provided. The lock assembly includes a lock pin mounted at a carrying frame interconnected between a lift linkage and the boom assembly. The lock assembly also includes a lock plate mounted at the lift linkage. In the raised position of the lift linkage, the lock plate includes a slot configured to align so as receive the lock pin. Once aligned, the boom is pivoted toward the folded, stowed position. As the boom pivots, the boom pushes the lock pin through the slot. The lift linkage is then lowered to seat the lock pin in the slot and thereby secure the lift linkage and supported boom in the raised, folded position.

  • Patent number: 6786143
    Abstract: A baler is described which has a collection chamber or duct and a baling chamber. Crop material enters the duct until a pre-determined level has been reached at which time a stuffer transfers the pre-compressed crop to the baling chamber. A control system is provided for calculating the ratio between the amount of crop material which should be formed into bales under optimal conditions and the rate of flow of crop material entering the duct. This ratio can be displayed and used to control the speed of the towing vehicle. The present invention uses the duct as a kind of measuring cylinder to determine the rate at which crop material is entering the baler.

  • Patent number: 6668620
    Abstract: A test for hydraulic leakage in hydraulic components uses a rate testing device having two circuits including a filling circuit that fast-fills the component with hydraulic fluid and a leakage circuit that measures the leakage rate of fluid flow through the component. The filling circuit is first connected to the component to fill the component. Once full, flow through the filling circuit is blocked and flow to the component is provided by the leakage circuit, which includes a leakage flow rate measuring device. The filling circuit provides a flow rate that is at least twice the flow rate that is provided by the leakage circuit.
