Greetings all, I bought this thing new in Oct 2012 with new plow. I don't drive it much but use it mainly for snow plow and some trail riding around my house. I missed the 25hr service and am now at 50 hrs. I could probably do the service myself but it really spits and sputs mainly in reverse as I do the driveway snow. I also saw an engine light come on briefly today. Odd that it would be spittin only in reverse???? Has newer gas which was my first thought. Just looking for some suggestions before I take it to the dealer for service or just tackle it myself. I'm an ok wrench, just not too motivated in the cold weather. Thanks.
