Estimating the term…
A down-pressure system for an agricultural implement has a linear actuator connected between a frame assembly and an opener assembly. A mounting structure for connecting the linear actuator to the opener assembly includes a bushing and an alignment member attached to the linear actuator. The bushing has protrusions extending transversely from opposite sides of a longitudinal axis of the linear actuator. Each protrusion has a curved engagement surface for engaging a flat surface on the opener assembly to prevent bending stresses on the linear actuator when the opener assembly is raised and lowered. The alignment member is arranged to lock the bushing into a predetermined rotational position about a longitudinal axis of the linear actuator relative to the opener assembly. The alignment member comprises a first structure that mates with a corresponding structure on the bushing, and a second structure that engages opposite sides of the opener assembly.
An agricultural implement, comprising:
In an agricultural implement having a frame assembly adapted for forward movement over a field, and an opener assembly having an opener arm with a first end pivotally connected at a first connection point to said frame assembly and a second end supporting a furrow opener, an adjustable down-pressure system for rotatably biasing the opener arm, the down-pressure system comprising:
In an agricultural seed drill having a frame assembly adapted for forward movement over a field, an opener assembly having an opener arm and a furrow opener, said opener arm having a first end pivotally connected to the frame assembly and a second end supporting the furrow opener, and a down-pressure system for adjustably biasing the opener arm, the down-pressure system comprising:
An agricultural implement, comprising:
