Radman, my 72" materials bucket measures 24" high and 24"-26" deep depending on where you measure to at the back of the bucket from the front edge, It does seem like your right in the middle with that machine having 12 more H.P. than the 4310 but only a slightly bigger frame. does the 72" standard and HD buckets have less volume than the light materials 72" bucket? if so then the standard or HD 72" should be good for your tractor. But 485 pounds sounds high, how much can the whole loader weigh, two guys can move it around. 485# would reduce your lift capacity which is only about 1500# for the 300cx on a 4310, does the loader get a higher lift rating when mounted on the 3720? are you stuck with the SS system or was it your choice? good luck. more pics attached.
