It used to be very common to mount the vac on the front. It was pretty standard to have it mounted on a Fisher plow mount. These days I'm seeing more mounted on the tail gate. It is sweet to be able to nose right up to a pile, but the long horizontal rigid run of pipe can be a pain to clear if it clogs. I'm holding off mounting my leaf loader until after I'm done with full cleanups on my regular customers. After that I may mount mine on the rear of my dump trailer and go chase piles...or not.
