Abstract: A longitudinally adjustable flow divider situated in the particulate material path of a spinner spreader between the bin and the rotatable disc divides the particulate material so that the particulate material is dischargeable on to the upper surface of the rotatable disc on first and second laterally spaced apart longitudinally oriented drop lines. An actuator operably connected to the flow divider adjusts a longitudinal position of the flow divider to longitudinally adjust drop points on the drop lines at which the particulate material is dischargeable on to the rotatable disc. Longitudinal adjustment of the drop points along laterally spaced apart drop lines on one spinner disc permits control over spread pattern to help achieve uniform distribution of the particulate material on a ground surface.

Abstract: A tillage implement has a frame connectable to a towing vehicle and at least two transverse rows of secondary tillage tools mounted on the frame, the at least two transverse rows comprising a row of main rollers mounted on the frame rearward of all other rows of the at least two transverse rows. The implement also has a transverse row of auxiliary rollers mounted rearward of the row of main rollers, the transverse row of auxiliary rollers independently pivotable vertically about a transverse pivot axis. The implement has at least one ground-engaging wheel. Independent pivoting of the row of auxiliary rollers allows an operator to increase tillage/field finish on the go or as needed.

Abstract: A method of controlling spread pattern of a particulate material broadcasted by a spinner spreader involves permitting particulate material to flow through a plurality of sluices situated in a particulate material path between a bin and a rotatable disc of a spinner spreader. Each sluice receives a portion of the particulate material and delivers the portion of particulate material to a radial and/or angular position on the rotatable disc. The radial and/or angular position on the rotatable disc to which the portion of particulate material from at least one of sluices is delivered is adjusted by longitudinally translating the at least one independently moveable sluice independent of all other sluices of the plurality of sluices to change position of the at least one independently moveable sluice relative to the rotating disc thereby changing the spread pattern of the particulate material broadcasted by the rotatable disc.

Abstract: An angle adjustable coulter wheel assembly includes a rotatable shank having a longitudinal axis defined by an upper portion of the shank. The longitudinal axis is oriented neither vertically or horizontally with respect to the ground when the assembly is mounted on a tillage apparatus. A coulter wheel rotatably mounted on the shank proximate a lower portion of the shank. An actuator rotates the upper portion of the shank about the longitudinal axis to cause the face of the coulter wheel to rotate about three orthogonal axes thereby changing orientation of the face of the coulter wheel with respect to the ground when the assembly is on the tillage apparatus. The coulter wheel assembly permits adjusting the angle of the coulter wheel in at least two planes permitting greater control over how much soil the coulter wheel disturbs during tilling.

Abstract: A self-propelled air boom spreader has a container mounted on a frame, the container having a product hopper and a noise-reducing fan assembly compartment therein with a fan assembly including at least a fan and a motor for operating the fan mounted in the noise-reducing fan assembly compartment within the container. The spreader has a product distribution system for receiving product from the hopper and an air system, including the fan assembly, for receiving product from the distribution system and distributing the product to the environment. Situating the fan assembly in the container provides a quieter operating spreader and distributes the center of gravity of the spreader forward to reduce overloading of the rear axle, to avoid overbalancing the spreader at the rear axle and to reduce undesirable torque of the frame at the rear.

Abstract: A spreader for spreading particulate material has a plurality of outlets transversely spaced-apart in a direction perpendicular to a direction of travel of the spreader. The outlets are configured to receive the material from a metering device and to dispense an amount of the material to mid-rows between crop rows on a field such that the plurality of outlets dispenses half the amount of material to an outermost mid-row compared to the amount of material dispensed to the other mid-rows. Also, the metering device may have two metering elements, which may be controlled to meter the material to only one side of the spreader. A centrally located outlet situated on a driving line of the spreader may receive material from both metering elements so that the centrally located nozzle can dispense the material whenever one or the other side of the spreader is not dispensing material.

Abstract: A tine harrow has a plurality of harrow tines mounted on and downwardly depending from a harrow frame. The tines are configured to be movable between a lowered position and a raised position, and at least one tine lowerable or raiseable to a different relative position in relation to a surface of a field than others of the tines. The ability to lower and raise individual tines or rows of tines to different positions in relation to a surface of a field provides more effective response of the tine harrow to changing land conditions. The positions to which individual tines or rows of tines are lowered or raised may be selectively set to further enhance effectiveness of the response of the tine harrow to changing land conditions.
