I have the 2038R coming in a few weeks and I went with the Frontier 60 inch box blade with scarifiers. Seems like many of you with similar tractors use the 72 inch. Did I go too small? I am using it to grade my steep gravel driveway and to make a new road thru the woods to my new garden. I assumed with the steep slope a loaded box would get heavy. Same with the new road, with roots, rocks, and all. Did I mess up?
