I am looking at getting a frontier box blade. I originally wanted a 60 or 66 inch but they have none in stock and I need it for this weekend. The guy at the tractor dealer says I can rent the 72 inch model for 100 bucks and if I like it I can put the 100 towards the purchase price which I think is around 800 bucks. Is a 72" box blade to big for a 3038e. Its a 38 hp tractor but its a light tractor in terms of weight.
