WOW ,just installed one on my Troy built 2003,7524 ,7.5 hp snow thower.seen it online for around $30.00 from Clairence someone. This guy had a great idea! I made one from the pic's that i seen not bad at all,some thick rubber,galvinized plate,1/4 20 locking wiz bolts An nuts and some thread lock. It took around three hours to fabracate and install.Just tested it on 12" plus of heavy snow that has been rained on all morning.Unbeliveable results thru the snow clear across the yard. So now hope dont have any problems with Bearings,gear box,belts wearing prematurly just not sure if this will effect anything else.anybody install one and in use for some time would like to know.
