A pneumatic delivery system for particulate agricultural products includes one or more compartment for containing and supplying one or more particulate product. An inductor assembly separately receives and fluidizes the particulate products and conveys the fluidized products to a metering assembly. The metering assembly separately meters each of the product flows and transfers the metered flows to one or more delivery units for applying the products. The pneumatic delivery system can be used on various implements, including planters and applicators for applying seeds, fertilizer, pesticides and other products.

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.

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.

A method for determining setting recommendations for an agricultural spreader includes the steps of: determining an uneven spreading-material distribution in a usable agricultural area or an uneven nutritional status of plants in the usable agricultural area, determining an ideal balancing distribution of spreading material that balances out unevenness of the determined spreading-material distribution in the usable agricultural area or unevenness of the determined nutritional status of the plants in the usable agricultural area, and determining setting recommendations for the agricultural spreader for implementing a balancing distribution of the spreading material, wherein the balancing distribution approximates the ideal balancing distribution.

A dispenser unit (1) for dispensing biological material, e.g. larvae or insects etc. The dispenser unit has a rotary arrangement (2) with a drive shaft (3) and a plurality of protruding vanes (4) positioned inside a housing (10) for encasing the rotary arrangement to form chambers (5) for containing biological material between respective neighbouring vanes and an inner wall (11) of the housing. A track (6) on the housing serves to engage with each vane or movable element to control the volume of the chamber between an inlet opening (20) in a top part of the housing and an outlet opening (21) in a bottom part of the housing. This allows the biological material to be received in the chambers at the inlet opening (20) and dispensed from the chambers (5) at the outlet opening (21) during rotation of the rotary arrangement. The dispensing unit is designed to provide for an expanding chamber volume as the chambers are being rotated from the inlet opening to the outlet opening. The dispenser unit has proven to provide a low mortality e.g. for dispensing living larvae. It can be transported by a drone or the like to spread biological material over a large area.

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.

An apparatus for combining planting implements enables an operator of a tractor to use both a conventional cultivating implement and a conventional broadcasting implement simultaneously. The apparatus is rigidly affixed to a conventional cultivating implement and comprises a support frame, a pair of brackets, and a connection bar. In combination, the support frame, pair of brackets, and connection bar provide a three-point connection whereby a conventional broadcasting implement may be attached thereto, thus enabling an operator of a tractor to use both a conventional cultivating implement and a conventional broadcasting implement simultaneously. In operation, at least a portion of the conventional cultivating implement is disposed behind the conventional broadcasting implement when the conventional broadcasting implement is attached to the support frame, thereby allowing simultaneous cultivation and broadcasting of constituents.

The invention comprises a deflector assembly for use with a spreading disc rotatable around a first axis, the deflector assembly comprising an array of deflector members concentrically disposed relative to the first axis, wherein a stream of particulate material discharged onto the deflector assembly is deflected onto a portion of the spreading disc.

A material spreader is provided. The material spreader includes a hopper for storing material to be a spread which feeds to a rotary spreader assembly. The rotary spreader assembly includes an impeller that rotates about a hub which is secured to an impeller shaft. The impeller includes two or more blades extending radially from the impeller shaft which spin to cause the material to be discharged from the assembly through a chute. The spreader includes a base with a pair of wheels linked via a wheel axle that allows for manual movement. A wheel axle gear set is mounted to the wheel axle such that the wheel axle and wheels mesh with an impeller gear set mounted on the impeller shaft. When the wheels rotate, the movement causes the impeller shaft to rotate and discharges the material through the chute.
