An apparatus includes a shaft, a first barrel, and a second barrel. The shaft has a first end, a second end, and a longitudinal axis of rotation. The first barrel surrounds a first portion of the shaft and is fixed to the shaft to rotate therewith. The second barrel surrounds a second portion of the shaft and is configured to rotate about the axis independent of a rotation of the shaft.

A spreader with a material divider that is adjustable from side to side so as to change a percentage of a stream of material which flows through portions of the material divider and also supports and moves laterally with a spinner while the spinner is adjustable longitudinally. The geometry of spread patterns can be adjusted by laterally manipulating the location of the material divider.

The invention comprises a chassis rail comprising an elongate frame member having a first end for mounting a head pulley and a second end for mounting a tail pulley; a first plurality of spaced-apart apertures to allow visual inspection of a plurality of bed rollers; and a second plurality of spaced-apart apertures to allow visual inspection of a plurality of return rollers.

A solid distribution system of an agricultural spreader includes a blower, a manifold having an inlet and a plurality of outlets and coupled to the blower, and a plurality of hoses. The manifold is configured to split air flow from the blower into flows through each of the plurality of outlets. Each hose is connected to one of the manifold outlets. A plurality of parallel rigid tubes are each connected to one of the hoses. A product hopper is configured to deliver solid particulate material to the rigid tubes without passing through the manifold or hoses. Vehicles having such solid distribution systems are also disclosed.

A method of spreading granular fertilizer includes driving a small framed truck over an electronically mapped area that is in need of granular fertilizer. As the small framed truck is driven over the mapped area, a GP S sensor is read to determine the location of the small framed truck on the mapped area. An electronic control determines the application rate of granular fertilizer needed to the left of the truck and the application rate of granular fertilizer needed to the right of the truck in relation to the location of the truck on the mapped area. The method includes dispensing left and right amounts of granular fertilizer from a hopper carried on the truck, with the left and right amounts being separately dispensed at rates determined in the determining step. Apparatus to carry out the method is also disclosed.

A feed control system for a spreader includes a section configuration module configured to output a section configuration and a section control module configured to receive the section configuration, determine a first actuator position based on the section configuration, and determine a second actuator position based on the section configuration. The feed control system also includes a belt speed module configured to receive the section configuration, receive a commanded belt speed, and determine a target belt speed based on (i) the section configuration and (ii) the commanded belt speed.

A chute for spreadable material for guiding spreadable material in the direction of a spreading disk of a spreader, having several guide surfaces which extend from a supply region for the spreadable material in the direction of the spreading disk.
