A spreader tool includes a hopper disposed above a base. The base includes a base opening that forms an egress. The spreader tool further includes an impeller disposed below the hopper. The spreader tool further includes a distribution gate that is positioned below the hopper and configured to selectively permit egress between the hopper and the base. The spreader tool further includes one or more motors that is operably coupled to a power unit and the impeller and the distribution gate. The one or more motors is configured to selectively rotate the impeller and the distribution gate. The spreader tool further includes a handle having a trigger assembly. The trigger assembly being configured to selectively command articulation of energy from the power unit to operate the motor to rotate the impeller and the distribution gate.

A broadcast spreader broadly comprising a frame, a hopper, an impeller, a set of wheels, and an electric hub motor. The hopper is supported by the frame and configured to hold a particulate material. The impeller is rotatably connected below the hopper and is configured to receive the particulate material from the hopper and spread the particulate material over a surface. The wheels are rotatably connected to the frame for traversing the surface. The electric hub motor is at least partially positioned in one of the wheels and configured to drivably engage the one of the wheels to propel the hopper along the surface.

A quick-connect top dress seal assembly for converting a standard broadcast spreader into a top dress spreader. The assembly includes a seal base, a compression spring, a seal lock, and a seal cap. The seal base couples to the bottom of a hopper of the spreader over a shaft of the spreader, and includes a ledge near one end and tabs near the other end. The compression spring fits inside the seal base and acts against a ledge in the seal base. A seal lock resides within the seal base and is held in place, against the spring force, via the tabs and a pin seat. A seal cap couples to the seal base to prevent entry of sand therewithin.

A swing disc spreader includes a swing disc which is arranged to be rotatable; and a swing driving mechanism, which is in transmission connection to the swing disc and used for driving the swing disc to swing reciprocatingly, the swing disc being configured to be in contact with materials during a swinging process so as to spread the materials outwards. In the technical solution provided in the present application, the swing disc spreader can achieve the spreading operation of materials simply by using one swing disc, such that the swing disc spreader has a simpler structure, achieves a reduced overall size and a relatively uniform spreading width, thus reducing the cost.
