My brushog is the only 4-foot implement I have for my 2015. My rear blade is 6-foot. My landscape rack and box blade are both 5-foot. I live on the side of a mountain, with a very steep driveway. Those size implements work very well with the 2015. I can go up the steepest part of my driveway with the boxblade pulling a full load of gravel. I had a 5-foot rear blade, but it was too small to do a decent job of cleaning ditches and clearing snow, so I traded it for a 6-footer.
