I mount a wheelhorse thrower on my hydro walk behind, we just made it up as we went.If you have the blade just attach it where the deck frame attached after you remove it and wala.I notice that one of the contractors in an issue of snowpro was doing this might want to look that up.
Exmark makes a snow plow that you can mount on a Turf Tracer in the place of the deck. I have never used one and my only fear is the tires not gripping. they also make a snow blower that also goes on in place of the deck on a Turf Tracer. This seems like a better option to me,!
