摘要：
A hopper spreader apparatus adapted for mounting to a vehicle, to be towed by a vehicle or to be pushed by hand, includes a sprayer apparatus for spraying liquid material as well as dispensing dry free-flow material. The hopper spreader apparatus includes a variable discharge mechanism, allowing adjustment of both the flow rate and the distribution pattern of the dry free-flow material particulate material being dispensed. The operation of the hopper spreader apparatus can be controlled remotely using radio frequency (RF) signaling. The hopper spreader apparatus obtains electrical power from an on-board battery and includes a battery charger to allow the battery to be charged when the hopper spreader apparatus is not in use.
