Abstract: A vehicle has a vehicle frame having a first end and a second end and a first siderail and a second siderail spaced laterally and each extend longitudinally from the first end to the second end. A caster wheel having a lateral axis is rotatably coupled to the vehicle frame towards the first end. Drive wheels defining an axis are rotatably coupled to the vehicle frame towards the second end. A prime mover coupled to the vehicle frame has a base and a vertical driveshaft, which is in operative communication with the drive wheels, extending from the base. The vertical driveshaft has a driveshaft axis closer to the second siderail than the first siderail laterally and closer to the caster wheel axis than the drive wheel axis longitudinally. The base is positioned vertically below most of the length of each of the first siderail and the second siderail.

The container also includes first and second ends and an opening formed at the first end for receiving the biological organisms. The apparatus has a dispensing port disposed at the second end for dispensing the biological organisms over a target location. The apparatus further includes an auger, driven by a motor and having a plurality of spiral like wire brushes, said auger mounted to and driven by a first motor; a spreader motor mount having a motor mount holding area for holding a second motor, the spreader motor mount having a motor mount connection area for connecting to the second end; and a spreader agitating device used for spreading the biological organisms or material over the target location.

Abstract: Method for a centrifugal spreader to precisely spread particulate material across an entire field with increased application rate, swath width and driving speed by utilizing a tiered disk spinner arrangement fed by a conveyor and guided by a material divider and an adjustable chute moveable in rotation around the spinner disk to achieve a desired symmetrical or asymmetrical spread pattern.

Abstract: A control apparatus for a broadcast spreader includes a gate adjustment dial mounted on, and generally coaxial with, a handle portion of a handle assembly of the spreader. Rotation of the gate adjustment dial in a first direction causes an increase in a current maximum discharge rate of the spreader and rotation of the gate adjustment dial in a second direction causes a decrease in the current maximum discharge rate of the spreader.

Abstract: A method for controlling an agricultural spreading machine during the discharging of spreading material on an agricultural area, comprising: using a conveyor belt of the spreading machine to feed the spreading material to be discharged along an idling section, which relates to a longitudinal section of the conveyor belt, wherein the idling section lies between a rate-setting plane, in which the feed rate of spreading material entering the idling section is set by a feed-rate-setting device of the spreading machine, and an ejection plane, in which the feed rate of spreading material leaving the idling section is ejected from the conveyor belt in the direction of a first and a second spreading disc.

Abstract: A seed delivery system for use in a seeding or planting machine that removes the seed from a seed meter by capturing the seed therefrom. The delivery system then moves the seed down to a lower discharge point and accelerates the seed horizontally rearward to a speed approximately equal to the forward travel speed of the seeding machine such that the seed, when discharged has a low or zero horizontal velocity relative to the ground. Rolling of the seed in the trench is thus reduced. Furthermore, as the seed only has a short drop from the outlet to the bottom of the seed trench, the seed has little vertical speed to induce bounce. The delivery system uses a brush belt to capture, move and accelerate the seed. By capturing the seed and moving it from the meter to the discharge, the seed is held in place relative to other seeds and the planter row unit. As a result, the seeds are isolated from row unit dynamics thereby maintaining seed spacing.

Abstract: A method for spreading broadcasting material using an agricultural spreader is provided, and in particular with an open-loop and/or closed-loop control device in which open-loop and/or closed-loop control with at least one adjustment parameter is provided for the spreader and is configured to influence on the basis of the at least one adjustment parameter a spread pattern of the broadcasting material that can be spread by the spreader, where a need for the adaptation of a control behavior of the at least one adjustment parameter is detected, and after the detection of the need for the adaptation of the control behavior, the control behavior of the at least one adjustment parameter is adapted; where a need for adjustment parameter adaptation for influencing the spread pattern is additionally detected, and one or more adjustment parameters with adapted control behavior are changed after the need for adjustment parameter adaptation has been detected.

Abstract: A broadcast spreader and methods of using the same. One method includes dispersing particulate material using a broadcast spreader having a hopper and an impeller by placing the spreader in a first configuration where a first set of through openings proximate a bottom portion of the hopper permit the particulate material to pass therethrough and fall onto the impeller to thereby be distributed in a first spread pattern, and shifting the spreader into a second configuration where a second set of through openings proximate the bottom portion of the hopper permit the particulate material to pass therethrough and fall onto the impeller to thereby be distributed in a second spread pattern. The first set of through openings includes a different number of through openings than the second set of through openings, and the first spread pattern is different than the second spread pattern.
