A discharge device includes a plurality of material conveying components, an adjustable shear ledge, and an adjustable shroud to convey materials from a container of a material spreader out onto an open area. The adjustable shear ledge includes at least one longitudinal mounting member such that the adjustable shear ledge may be translated towards or away from the plurality of material conveying components to maintain a predetermined gap distance. The adjustable shroud may also be pivotably connected to the adjustable shear ledge such that the adjustable shroud can be pivoted towards or away from the plurality of material conveying components. The adjustable shear ledge and the adjustable shroud may be moved accordingly to maintain a preferred gap distance and to maintain concentricity with a swing of the material conveying components in order to reduce wear on components and promote spread performance of the material spreader.

Material spreader

A drive system includes a drive housing and one or more drivetrain cartridges. The one or more drivetrain cartridges enables better manufacturability by allowing drivetrain components to be installed together outside the housing and then installed as a unit together into the housing. Serviceability is improved by allowing one or more of the drivetrain cartridges to be removed individually from the housing for maintenance or repair. The housing may include mounting surfaces to securely engage the one or more drivetrain cartridges to the housing to prevent play. The housing may include a bottom or side panel with installation mounts to fasten the drivetrain cartridge or cartridges securely to the bottom or side panel of the housing.

Cartridge drive

A spreading apparatus for spreading material onto a target area is disclosed. The spreading apparatus includes a container for the material, a discharge unit which discharges the material, a deflector door disposed on a discharge port of the discharge unit, a positioning device which positions the deflector door and a controller configured to control the deflector door so that the deflector door is positioned between a first closed position and a second open position. The material is substantially prevented from exiting through the discharge port when the deflector door is in the first position. The deflector door may further be positioned at a position between the first closed position and second open position to control a distance of the material discharged from the discharge port.
