A switch actuation assembly is provided with a support means for supporting the switch in a fixed position relative to orientations of a moveable member. A motion response element is operably connected to the moveable member for being moved in one of two directions in response to movement of the moveable member toward one of the orientations and for being moved in the other of the two directions in response to the movement of the moveable member toward the other of the two orientations. An actuating member is provided for engaging the switch to actuate the switch from a first position to a second position. The actuating member is in frictional contact with the motion response element whereby the actuating member is moved by the response element until any force of resistance to the movement of the actuating member exceeds the static friction force.

A hoe-opener assembly having a 'float' feature is disclosed. The present invention ties operation of several hoe openers to a common framework so that uniform depth control can be maintained. The hoe-opener assembly of the present invention is drawn behind an agricultural implement having a tool bar, and comprises a vertically movable framework. A frame lift-and-lower arrangement is provided for adjusting the spacing of the framework relative to the ground. The hoe-opener assembly includes a plurality of spring-biased hoe openers, each pivotally carried for limited pivotal movement by the framework at spaced intervals along the length thereof. A biasing-spring arrangement in operative association with each hoe-opener is provided whereby each hoe opener is substantially fixed against independent movement, relative to the framework.

A foldable and swivelable screw conveyor mounted on a transportable storage hopper is disclosed. The storage hopper typically contains particulate material such as grain, fertilizer and the like. The present invention is directed to a spatially-compact hopper-loading screw conveyor which can be folded onto a frame portion of the storage hopper, and which can be secured thereto. The conveyor is foldable along a hinge joint and swivelable along a swivel joint. The screw conveyor has an inlet chute which can be placed on the ground. The foldability and swivelability features allow the screw conveyor to be carried in a spatially-compact fashion on the storage-hopper frame when not in use and further allow the inlet chute to be placed on the ground and extended away from the storage hopper, to convey particulate material into the storage hopper, as desired.
