Hello, first I just wanted to say thanks for all the helpful info I've received from this site before I even joined! Just purchased an '04 1/2? sportsman 500ho 50th anniversary edition from my friend. Spent the last 2 days wiring and installing a new warn pro 2500lb winch and 60" plow. What a treat that was. Two wrong winch mounts later and some cuts and lots of swearing, its ready to rock! Lol Anyway, after snowblowing 600+ ft of driveway for years I was excited to try it out and retire the snowblower! I hit my first snow bank and moved it about an inch before I lost traction. Come to find out my awd is not working. Anyway, with the help of previous posts on this forum I've narrowed it down but I'll post my questions in the proper forum. Sorry for the long intro, but it's been quite the learning experience over the last two days!
