摘要： A harrow has a frame, tines pivotal on the frame and each a lower arm with a soil surface under the harrow. An actuator on the frame can shift a bar frame shiftable horizontally on the frame. Respective spring biasing units above the axes each have a guide element connected to the bar frame and displaceable therewith through a predetermined displacement path, a connecting element connected to respective upper arms of the tines, a first compression spring bearing on both of the elements and biasing the other element away from the one element so as to press the lower arm downward into the soil surface during movement of the respective guide element through the path, and a second compression spring bearing continuously on one of the elements and engageable with the other of the elements after displacement of the respective spring-biasing unit only through a part of the path.

摘要： An agricultural row unit for use with a towing frame hitched to a tractor includes an attachment frame adapted to be rigidly connected to the towing frame, a linkage pivotably coupled to the attachment frame, and a row unit frame having a leading end pivotably coupled to the linkage to permit vertical pivoting movement of the row unit frame relative to the attachment frame. A hydraulic cylinder coupled to the attachment frame and the linkage, for urging the row unit frame downwardly toward the soil, includes a movable ram extending into the cylinder, and a hydraulic-fluid cavity within the cylinder for receiving pressurized hydraulic fluid for advancing the ram in a direction that pivots the linkage and the row unit frame downwardly toward the soil. An accumulator positioned adjacent to the hydraulic cylinder has a fluid chamber containing a diaphragm, with the portion of the chamber on one side of the diaphragm being connected to the hydraulic-fluid cavity in the hydraulic cylinder, and the portion of the chamber on the other side of the diaphragm containing a pressurized gas.

摘要： A finishing assembly for an agricultural implement includes a first rolling basket and a second rolling basket. The finishing assembly also includes a basket support assembly coupled to the first rolling basket and the second rolling basket and configured to support the first rolling basket and the second rolling basket relative to each other. The finishing assembly further includes a linkage pivotably coupled to the basket support assembly at a first pivot point. The finishing assembly even further includes a hydraulic actuator pivotably coupled to the basket support assembly at a second pivot point, wherein the hydraulic actuator is configured to damp pivoting of the basket support assembly about the first pivot point in both a first pivot direction and a second pivot direction, the second pivot direction being opposite the first pivot direction.

摘要： An agricultural implement includes at least one row unit having a plurality of support members, each of which is pivotably coupled to an attachment frame or another of the support members to permit vertical pivoting vertical movement of the support members, and a plurality of soil-engaging tools, each of which is coupled to at least one of the support members. A plurality of hydraulic cylinders are coupled to the support members for urging the support members downwardly toward the soil. A plurality of controllable pressure control valves are coupled to the hydraulic cylinders for controlling the pressure of hydraulic fluid supplied to the cylinders. A plurality of sensors produce electrical signals corresponding to predetermined conditions, and a controller is coupled to the sensor and the controllable pressure control valves. The controller receives the electrical signals from the sensors and produces control signals for controlling the pressure control valves.

摘要： Agricultural machines and implements have a need to adapt to changing environments. A closing system for an agricultural machine has a need to adapt to changing ground surface. The closing system includes a closing device pivotably connected to the agricultural machine, a passive mechanical element that is operable to apply an initial amount force to the closing device, and an actuator that is operable to apply an actuator force to the passive mechanical element to increase the amount of force that the passive mechanical element applies to the closing device. The actuator can be a linear actuator having an adjustable stroke length to vary the amount of actuator force applied to the passive mechanical element. The passive mechanical element is operable to absorb a shock force as the closing device traverses a ground surface. The passive mechanical element includes one or more springs adjacent the actuator.
