A material spreader assembly for the broadcast spreading of particulate material from the trailer hitch of a vehicle. A hopper for storing the particulate material is supported by a frame having a trailer hitch coupler for connection to the vehicle. A spreader including a spinner driven by an electric motor receives and disperses the particulate material. A control circuit receives electric current from the vehicle via a plug interface and a wiring harness and controls the operation of the spreader. A remote communicates user commands to the control circuit. The control circuit includes a motor control processor that controls a motor power relay and a motor driver to gradually ramp up the current supplied to the spreader for start up the spreader while preventing a high transient current draw spike. Component feedback sensors enable the motor control processor to provide an emergency shut off feature and warning signals.

The invention relates to a dispensing device for dispensing filler material onto a surface to be filled, said device comprising a main frame and at least one conveying belt guided thereon for delivering the filler material to at least one output portion, wherein both in and against a direction of travel at least one distribution brush is arranged on the main frame behind the output portion for distributing the filler material on the surface to be filled.

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.

A sand bunker rake/infield groomer vehicle having a frame; a plurality of wheels to traverse a driven surface, wherein the wheels are rotatably mounted to the frame; a power source mounted to the frame; and a rear attachment structure attached to the frame, wherein the rear attachment structure provides a joint enabling rotation; a bracket including a shaft wherein the bracket is configured to cooperate with an associated rake/grooming attachment; and a pivoting bracket mounted to the frame.

An autonomous ground maintenance system comprising a vehicle comprising a chassis supported upon a ground surface by ground support members, a container supported by the chassis, the container defining a discharge outlet operable to disperse treating material held within the container to a target area of the ground surface, a gate adapted to selectively open and close the discharge outlet, a sensor adapted to identify the target area, and an electronic controller supported by the chassis, the controller being in communication with the sensor and the gate. The controller is adapted to position the chassis at a location proximate the target area such that the discharge outlet is capable of delivering the treating material to the target area and energize the gate to open the discharge outlet.

A method of removing debris from an area of turf grass can include providing a grass treatment system including a comb having a leading edge comprising a plurality of comb teeth, wherein the comb is mounted transversely to a direction of travel, and a substantially cylindrical brush positioned above the comb and configured to engage at least a portion of a top surface of the comb, wherein the brush rotates relative to the comb. The method can include positioning the grass treatment system closely adjacent to the turf grass such that the comb engages debris on and around the turf grass surface, and moving the grass treatment so that (i) the comb engages the debris, (ii) the rotating brush removes at least a portion of the debris from the surface of the comb, and (iii) the rotating brush does not come into contact with the turf grass.

An automatic treatment material spreader device that is designed to automatically spread a treating material such as a salt or fertilizer for treating lawns, gardens, driveways, and parking lots. The device includes a rectangular body having a truck bed for storing treatment material, tank treads for mobility, and a funnel with rotating blades for metering and spreading the treatment material to a target area. The device is remotely controlled by an operator through a software application wherein the device can run on electrical supply provided through an internal battery. The internal batter can be charged by a wireless charging dock. The device can be programmed through the software application to spread the treatment material within a specified area and a specified treatment schedule. The device provides real time information about its location, material volume, and battery status.

There is a hopper having a substantially closed interior space that is configured to receive a binder, a fill assembly that is configured to be in fluid communication with the interior space of the hopper, and an exit port. Secured to the hopper is a base with at least one carrier. A pneumatic pump is secured to the hopper. An ingress pipe is secured to be in fluid communication with the pneumatic pump. A valve housing is secured to the ingress pipe and the exit port of the hopper. A valve is secured within the valve housing. An egress pipe is secured to the valve housing, and a spreader bar is secured to the egress pipe.
