The present invention relates to a wheel driven spreader having an unloader which can be mounted or dismounted, and which thus requires no needs for an additional unloader to standby, but facilitates easy separation and movement installation of the unloader, and allows a safe pillar to be folded, causing no interference with the ground when spraying fertilizers. The present invention provides a wheel driven spreader having an unloader which is composed of: a main body frame equipped with wheels and connection devices, which can run by using the traction force from a tractor; a hopper which is installed on the top of the main body frame to store fertilizers and which can spread sterilizers by receiving the rotational force from the wheels and operating a mesh chain conveyor and a spreading plate; an unloading device frame fixed and mounted in the main body frame; a crane unit composed of an extendable boom which is vertically supported in the unloading device frame, allowing a rotation and a winch installed in the boom to wind wires; a safety pillar composed of a carriage which can be retracted into the unloading device frame by sliding over the main body frame and an extendable support held up by the carriage; and a hydraulic controller unit which controls the pressure of fluids supplied from the tractor in order to extend the crane boom and the safety pillar′s supports and to control winch winding from the crane unit, and which allows mounting of stacking panels instead of the hoppers installed in the wheel driver spreader to carry items as a trailer if necessary. |
