We bought this spreader 2 years ago. It has only been used 3 times with sand only, has never had any salt in it, works great! Bought it from northern tool and all the info about it can be found on there site but some key features are vibrator for hopper, internal auger, variable speed rubber paddle for material, can do large areas in a single pass, mounts easily on any 2” receiver and has controller that runs into cab. Asking $1500 OBO. Call 620-791-7191 for any other info!
