Claims

1. An attachment for a skid steer loader comprising: (a) a support frame having a width, length and height, a first and a second end with the first end being of greater width and height than the second end, and adapted to support a hopper, a conveyor system, a spreader system, a spreader system angular adjustment, a hydraulic system, at least one wheel, at least one contact roller, and a universal mounting plate;(b) a hopper for receiving construction material and directing it in a downward direction, having an open, a collapsible end, and being attached to the support frame at the first end;(c) a conveyor system attached to the support frame at the first end, at a sufficient distance beneath the hopper as to permit the conveyor system to receive construction material from the hopper and redirect it in the direction of the open end of the hopper;(d) a spreader system pivotably attached at the first end of the support frame, having two walls connected to each other to form a right angle (a spreader elbow), a guide rod and hydraulic cylinder/ram assembly attached to each other in a manner that permits the hydraulic cylinder/ram assembly to move the spreader elbow in the same direction as the open end of the hopper;(e) a spreader system angular adjustment having a first and a second ends pivotably attached, respectively, at the first end of the support frame and to the hydraulic cylinder/ram assembly of the spreader system as to cause the spreader system to change its angular position with respect to the support frame when the spreader system angular adjustment is activated;(f) a hydraulic system for powering the conveyor system and the spreader system, having a gear box and hydraulic motor assembly, a hydraulic cylinder/ram assembly, and at least one two-way hydraulic valve/controller all attached to each other, to the support frame, and to an external hydraulic power source, such as that of a skid steer loader;(g) at least one wheel rotably attached at the first end of the support frame in a manner that maintains the first end of the support frame above ground level and permits the rolling of the support frame when it is pushed or pulled by a skid steer loader;(h) at least one contact roller rotably attached at the first end of the support frame in a manner that permits the contact roller to rotate when it comes in contact with an external wheel; and(i) a universal mounting plate attached at the second end of the support frame in a manner that allows the mounting plate to be engaged by a skid steer loader.

2. The attachment for a skid steer loader of claim 1, further comprising removable and adjustable supporting means for providing additional support to the open end of the spreader elbow.

3. The attachment for a skid steer loader of claim 1, where width, length and height of the support frame are small enough as to allow a skid steer loader operator to have a direct line of sight with the construction material that is being deposited by the spreader system.

4. The attachment for a skid steer loader of claim 3, where the skid steer loader attachment is light enough as to be lifted over obstacles by and when engaged to a skid steer loader.

5. The attachment for a skid steer loader of claim 4, where the support frame is made of steel.

6. The attachment for a skid steer loader of claim 4, where the support frame is made of aluminum alloy.

7. The attachment for a skid steer loader of claim 4, where the hopper is made of reinforced rubber.

8. The attachment for a skid steer loader of claim 4, where the hopper is made of engineered plastic,

9. The attachment for a skid steer loader of claim 4, where the hopper is made of steel.

10. The attachment for a skid steer loader of claim 4, where the hopper is made of aluminum alloy.
