I am looking for a disc harrow for my Nortrac 254 (25 h.p. , 4wd). I am looking at a "King Kutter" 66-inch unit. My questions is: before I pull the trigger on the deal and have them ship it half-way across the country, will the tractor pull this? I don稚 want to get more implement than I can pull. Will the 66" work, or do I need to get something smaller?
