  • Patent number: 10327372
    Abstract: A mounting structure for mounting a pivot arm to an implement has a cylindrical member, an adjusting sleeve, and a mounting bolt extending through the cylindrical member and adjusting sleeve to fix the cylindrical member and adjusting sleeve together. The cylindrical member extends through a bore of a bearing housing for rotation within the bearing housing. The adjusting sleeve has a threaded external surface. A disc spring is positioned on the adjusting sleeve. An adjusting nut is threaded onto the threaded external surface of the adjusting sleeve. The adjusting nut can be tightened to compress the disc spring to create a lateral bearing force against the bearing housing. The bearing housing can be integral with a pivot arm for mounting a gauge wheel assembly on a planter row unit, or the bearing housing can be a fixed part for mounting a pivot arm for a closing/press wheel on a drill.

    Abstract: In order to achieve a solution which assists a farmer in working land in a way which reduces the risk of soil compaction of the land there is, among others, a method of determining a work trajectory to be followed by an agricultural work vehicle. The method includes accessing a soil carry capacity map of an area of land to be worked by the agricultural work vehicle, receiving load data of the agricultural work vehicle so as to determine the agricultural work vehicle load and determining the work trajectory to be followed by the agricultural work vehicle. The work trajectory is determined by correlating the soil carry capacity map and the load data of the agricultural work vehicle, so as to optimize that the area to be worked with low carry capacity is worked with low agricultural work vehicle load.

  • Patent number: 7757620
    Abstract: A garden machine allows a user to perform various gardening functions with a single machine by allowing the user to easily interchange implements placed on an implement mounting shaft of the machine. The garden machine includes a frame and an implement mounting shaft. The user, faced with a job to do, selects the implements best suited for the job and mounts the selected implements on the implement mounting shaft. The user then manipulates the machine to do the job. The machine can be hand powered or be powered by an engine or motor. A seed drill of the invention includes seed discharge tubes spaced around the circumference of a disk. Each seed discharge tube communicates with a seed reservoir in the disk through a displacement operated valve arrangement. As a planting head is displaced toward the disk against a spring bias, the displacement opens the seed discharge tube so that a seed is discharged from the reservoir into the tube and is delivered to the ground.

The pivot arms are pivotally mounted to the wing frame segments by a rock shaft having an actuator bell crank. The bell crank is coupled to a linear actuator for rotating the rock shaft relative to the wing frame segments. The pivot arms have a working position, wherein the planting units are in contact with the ground, an intermediate holding position, wherein the planting units are raised out of the ground, and a transport position, wherein the planting units have been pivoted on their noses into their substantially vertical transport position. To maintain the rear rank of planting units in the intermediate holding position, a U-shaped stop is placed over the linear actuator so that the linear actuator cannot retract.

  • Patent number: 6520100
    Abstract: A twin row planter (10) includes planting units (20a-26b) arranged in pairs (20-26). Each pair (20-26) is configured and positioned for planting two rows (78,80) of seeds less than about ten inches apart to produce two rows of crops in order to increase the yield of the plot. With this spacing, the rows (78,80) in each pair are close enough to simulate a single row enabling the use of a conventional cultivator, sprayer or harvesting machine.

  • Patent number: 6443079
    Abstract: An agricultural machine has a movable rack (10) having at least one main wheel (16, 18), a hitch (12) which is arranged on the rack (10), a reservoir container (14) which is carried by the rack (10) and/or the hitch (12), and an agricultural implement (20) which is attached to the rack (10) at the rear in the direction of travel and has a plurality of rear support wheels (28). The machine is developed to the effect that the at least one main wheel (16, 18) is positively steered as a function of the pulling direction of a traction force which is exerted on the hitch (12). Such a machine is particularly compact and maneuverable even when the reservoir container is large.

  • Patent number: 6237696
    Abstract: A ground opener unit for a seeding or planting unit includes an arm attachable to an implement frame and a disc rotatably mounted to the arm for forming a furrow in the ground. A scraper assembly includes a scraper plate defining a scraper edge for contacting and scraping a surface of the disc. The scraper plate defines a mounting region remote from the edge. A scraper plate mount secures the scraper plate adjacent the disc and a resilient pad of material is interposed between the plate mounting region and the scraper plate mount. A spaced pair of fasteners extend through the mounting region to secure the scraper plate and resilient pad to the scraper plate mount. The fasteners are located in selected positions in the mounting region relative to the resilient pad such that the scraper plate is capable of being tilted or rocked when said scraper edge encounters irregularities thus assisting the scraper edge to follow the disc surface during use.

  • Patent number: 6125775
    Abstract: A system for ensuring the uniform height of gauge wheels for a towed implement assembly such as a seeder. The seeder has a frame structure with a series of front gauge wheels suspended by the front of the frame structure. A greater number of rear wheels are suspended by the frame structure to the rear of the front gauge wheel. A tow hitch is pivotally connected from the front of the frame structure for coupling to a work vehicle. A front bar having a first end and a second end is coupled to the tow hitch. A center actuator such as a hydraulic cylinder is coupled to one end of the front bar. A rear bar is placed in contact with the opposite end of the hydraulic cylinder. The front gauge wheels are raised by extending the cylinder and causing force to be applied to the front and rear bars. In this manner, the weight on the front wheels is distributed to the work vehicle via the tow hitch and the rear wheels.

  • Patent number: 6119608
    Abstract: The planer row unit has a unit frame with a front member that is adapted to be secured to a tool bar. A sub frame is secured to the front member by parallel links. A furrow opener disk, a seed shoe and a gauge wheel are secured to the subframe.A cam plate supported by a spring to the rear of the seed shoe presses seeds into moist soil in the bottom of a seed furrow. A seed covering disc is supported by a covering disc shank to the rear and to one side of the furrow opener. The covering disc has a circular plate portion that faces downwardly and forwardly, moves loose soil from the furrow opener into the seed furrow and rotates about a central axis that extends downwardly from a horizontal plane. A flange, with notches extends radially outward and rearwardly from the outer periphery of the circular plate portion, rolls and slides along the surface and limits soil penetration by the covering disk.
