Agricultural apparatus with hydraulic cylinder and manifold for a row unit
First Claim
Patent Images
1. An agricultural row unit comprising:
- an attachment frame adapted to be rigidly connected to a towing frame;
a linkage assembly pivotably coupled to the attachment frame to permit vertical pivoting movement of the linkage assembly relative to the attachment frame;
a hydraulic actuator coupled to the linkage assembly for urging the linkage assembly downwardly toward the soil; and
a hose connection manifold mounted adjacent to the hydraulic actuator for circulating hydraulic fluid between a hydraulic source and the hydraulic actuator, the hose connection manifold having a modular port for accepting, one at a time, a removable control valve and a port plug.

Abstract
An agricultural row unit includes an attachment frame adapted to be rigidly connected to a towing frame, and a linkage assembly pivotably coupled to the attachment frame to permit vertical pivoting movement of the linkage assembly relative to the attachment frame. The row unit further includes a hydraulic actuator coupled to the linkage assembly for urging the linkage assembly downwardly toward the soil, and a hose connection manifold mounted adjacent to the hydraulic actuator for circulating hydraulic fluid between a hydraulic source and the hydraulic actuator. The hose connection manifold has a modular port for accepting, one at a time, a removable control valve and a port plug.

11. An agricultural system, comprising:
-
a hydraulic source for supplying pressurized hydraulic fluid; a towing frame attachable to a towing vehicle; a first row unit attached to the towing frame and including a a first hydraulic actuator for urging the first row unit downwardly toward the soil, and a first hose connection manifold having a first modular port and mounted adjacent the first hydraulic actuator for circulating hydraulic fluid between the hydraulic source and the first hydraulic actuator, the first hose connection manifold having a removable control valve inserted into the first modular port; and a second row unit attached to the towing frame and including a a second hydraulic actuator for urging the second row unit downwardly toward the soil, and a second hose connection manifold having a second modular port and mounted adjacent the second hydraulic actuator for circulating hydraulic fluid between the hydraulic source and the second hydraulic actuator, the second hose connection manifold having a removable plug inserted into the second modular port. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
