AgriLinc had a range of Herbst trailers on its stand, including a simple but cleverly made gravel cart for back-filling drainage trenches. The 8t capacity hopper drops material onto a sliding cross-conveyor, which can distribute material to either the left or right of the trailer thanks to its side-shift facility. A hydraulic shutter controls the rate of flow of stone into the trench.  Requiring three spool valves, the 8-tonner retails for £8,750.
