Good question...off topic..hijacking the thread...Is it possible to modify a Lesco spreader to serve as a pull behind spreader? For behind your ATV?
Naturally if you pulled it backwards you must reverse the impeller spin--in my opinion. However that is not hard; I have done it accidentally, you simply install the axle backwards when rebuilding it.
Probably it is simpler to pull it forwards. You would have to attach a "trailer hitch" made of conduit to the two side tubes under the hopper. You could use the hopper bolts if you got longer bolts. Perhaps you would need a couple screw clamps to further stabilize the two tubes. Then you would naturally need a long pole made from PVC pipe attached to the open lever, to open and close the hopper.
