I have a JD 757 that the Specs say weighs 1300 lbs. But. I have three weight bars on the front that are stock and must weigh 100 lbs. Caps on the casters that must weigh 20 apiece, and of course the roll bar deal. Im not sure but the bars and the caps might be add ons because I have the bagger system for fall use. Figuring that......does the 1300 lbs include the roll bar which has to weigh 100 lbs? Im takin the roll bar off....the weights off and trying to lighten this machine up.
