That is totally opposite of my brother-in-law with his old 1486 International that I can keep track of even when he is over a hill in the field we were chopping by the stream of black smoke. His tractor is rated at 145 PTO HP, my M135GX is rated at 110 PTO Hp, yet I out chop him by a 4 to 3 margin. I don't know if his tractor is that down on power due to old age. Choppers are same model and condition. It has been interesting to see how this tractor will do against his.
Was the 1486 tested at Nebraska?
