Hey, I have a 2015 gear 4wd, I am looking at buying a boxblade, I have narrowed down to either an atlas hd or a united, the tractor is 54" wide. I am curious which width most 2015 owners use, I am thinking 5 foot to cover tracks ( since most 54" blades are more $$$ ) or would the 4 foot be a better choice for the horspower. Any input would be great.
