My new 4110 is coming Tues. I am looking at Five Point by King Kutter equipment at a farm supply store. My tractor will have industrial tires. Will I be better off with the 4 or 5 foot box blade. I am also going to buy a tiller. King Kutter has a 4 footer weighing 600 lbs. requiring 20-35 hp according to the brochure and a 5' weighing 690lbs requiring 25-40 hp. My pto hp is 17, I believe. Are these minimum or maximum hp requirements? Is the King Kutter equipment a good quality brand? They look as good as the other brands I have looked at. Any help will be appreciated. By the way, the 4' box is $279 and the 4' tiller $1195.
