I have a 19HP, B8200, 4WD kubota. My question to a seasoned veteran is , I was told elsewhere that I should use a 48" rear mower as compared to a 60". I've looked and found a 60" is cheaper than a 48". But a 48" is what a tractor this size should pull, but if I could get away with a 60", I'm going that route. Any and all suggestions are appreciated. Thanks Tom
