My introduction to Wheel Horse began in the summer of 1997, immediately following high school graduation. I worked at Howard's in Coudersport (former Tucker's) until November of that year. I assembled new units, and did maintenance & repair on Kubota, Wheel Horse & Ski-doo equipment. I remember seeing pictures of the 520xi that fall. If I recall, we got one unit in the fall just before I left. I always thought they were pretty neat. Well I got one last week in ROUGH shape. So far I got it un-stuck ( motor was ceased) & running well. I have some questions on this machine, and after reviewing several sites & pages, this looks to be the best "spot" For "street cred" I have attached a link to my shop video. Karl J.
