Help newbie question. I tried installing a Denali plow with belly mount on a 2015 sportsman 570. Installing the 5th carriage bolt is hard because. Have to remove the battery and put the bolt on top and the nut on the bottom. How do I remove the battery on a 2015 sportsman 570? Do I remove the Side panel and foot rest panel first? Or is there an easy way of getting through it? I tried looking online, but can’t find anything. The manual is very vague. Any tips highly appreciated
