 Cleveland, MS. Own small farm near Booneville, MS | In my admittedly limited experience I'm not sure that the JD 3300 would compare to an IH 615. I think it's more like JD and IH combine sizes in those years kind of fit in between each other. We ran a 4400 and a 615 together in the same field with me driving the 4400 and my brother on the 615. Both had 14' grain heads. The 4400 would outrun the 615 by about 1/2 mph. Based on that I don't believe a 3300 would keep up with a 615, but I never ran a 3300 so I'm not sure. I do believe that a 715 was more combine than a 4400. |
