The ends of a saddle link are received in sockets formed on gauge wheel arms; and a yoke (or ring-shaped link) pivotally mounted to the frame engages a central saddle bearing surface on the saddle link. The wheel arms, saddle link and yoke are constructed and arranged such that when one gauge wheel raises when it encounters an obstruction, the other lowers and the frame raises by about one-half the distance which the first gauge wheel is raised.Field of SearchAdjustable gauge wheels separate from packerPacking means gauges opener Rotating gauge means Gauge means for auxiliary frame Furrow closer Rotating furrow closer Disk Plural Packer wheel Plural Pinch adjustment Plural cooperating disk openers Paired press rims (e.g., planter press wheels, etc.) Smooth roller with groove, rim or disk Tools on different axes in mutual driving relationship Yieldable material rim (e.g., rubber, etc.) DRAFT, PITCH OR GROUND LEVEL RESPONSIVE DEPTH CONTROL WITH GROUND SUPPORT VERTICALLY ADJUSTABLE RELATIVE TO FRAME Plural ground supports vertically adjustable relative to each other and the frame Tool land ground support moved together relative to frame Plate or side forms bearing surface Trunnion assembly to side of rod | |
