New sportsman 570 2015 help regarding break in

I apologize for the newbie post, but this is my first ATV sportsman 570 base model 2015. I read the manual regarding break in and it stated that first 25 hours do not go too fast and squeeze on the throttle too hard and do not stay in the same rpm all the time. The thing is I bought this ATV mainly for plowing and light trailing in my backyard. I have 3 acres in my property with a trail and 10,000 acres after that of wild life reserve. I haven’t ventured out of my property due to fear of trespassing so I’m limited in distance on how far I can really go with this ATV. Today is the first time I tried it and I was able to go only 10-15 mph varrying the speed for a total of 5 miles today. I can’t go really fast cause it is a gradual incline to go up through the trail. Will my conditions affect the break in or should I take it somewhere so I could break it in more effectively before I use it for snow plowing. It’s October right now and here in NJ we may get snow as early as first week of December. Any thoughts about this will be highly appreciated.
