I was wondering how many of you use a walkbehind to mow 4+ acres? Of course there would have to be a sulky involved but has anyone done this? I have one yard that is right over 4 acres and im pretty sick of using my tractor on it. Its the only yard i have that is over 1 acre so its kinda a pain in the butt. Its very wide open with not one tree but there is a drainage ditch that is about 100 yards long along the road with a slope a little over 15 degrees. How would a 32"-36" walkbehind work on a yard like this?
