Abstract: A seed delivery device including a frame defining at least one seed chamber. The frame includes a sidewall and an air permeable floor. Seed can be received and deposited on the air permeable floor through an input port. An air input channel is utilized to introduce an air stream into the seed chamber and direct it through the air permeable floor such that seed is lifted from the air permeable floor to an outlet port. An air bypass channel is configured to separate the air stream into a first stream that is directed through the air permeable floor and a second stream that is directed through the bypass channel and recombined with the first stream, at a point prior to the output port.

Abstract: A declutching device for a seed drill distribution element including a locking element and a support element on which the locking element is mounted, in which the locking element allows two stable positions relative to the support element and can be moved between these, the locking element being configured, when in a stable position, to be able to declutch the distribution element.
Abstract: An agricultural implement for forming a furrow in a soil, is described and which includes a rotatable shank; a resilient, movement limiting member disposed in force transmitting relation relative to the rotatable shank; and a pair of wheels mounted for earth engaging movement, and respectively positioned on the opposite sides of the rotatable shank, and wherein the pair of wheels are positioned substantially laterally outwardly and rearwardly of an intended direction of movement of the shank.
Abstract: An implement for an agricultural machine includes a plurality of discs arranged to create furrows and a plurality of dispensers designed to provide at least first and second depositing locations. The first depositing location lies at a height close to the lowest point of the disc to enable deposition of material at the bottom of a furrow. The second depositing location is located such that the material is deposited into or onto the top of a soil flow created by the discs.
Abstract: Disclosed is a method for controlling the above-ground "raise height" of a seed-planting row unit on an agricultural planter having a row marker, a marker switch and a positioning assembly such as a solenoid valve and hydraulic cylinder for raising and lowering the row unit. The method includes enabling the positioning assembly to raise the row unit and changing the marker switch from its first to its second position when the row unit reaches a predetermined height. The positioning assembly is thereby disabled. Such assembly is re-enabled after a brief time delay. The method is carried out using a unique implement control circuit connected to the marker switch and the positioning assembly.
Abstract: A tramlining device is provided for a seed drill having shutters associated with respective seed spouts and controlled by individual fluid pressure operated actuators for improved flexibility in selecting the tramline spacing. The actuators are preferably such that when pressurized they close the shutters to produce tramlines. Fluid pressure is tapped from the rams that force the coulters into work. Preferably, a control valve in the fluid supply line comprises a valve member that is urged closed by the supply pressure but is opened by a plunger controlled by a bout register. Preferably, a solenoid operated plunger is provided to override operation of the bout register.
