We run a Parker 739 behind our 4760 Deere FWA. Seems there is a lot of weight on the hitch with this cart but we have never had anything else to compare to. A larger cart would be nice this fall as we have upgraded combines and keeping up with a 750 bu cart is going to be borderline especially in oats. Power has never been an issue for us, we have flat firm dirt. What can I look at that may put a little less stress on the hitch and give me another 100 to 150 bu capacity? What are others using with a comparative sized tractor? Thanks.
