There is a long history of Massey on our farm,26,82,410,510,750,860,8570.The 8570 was the shortest lived though.For what new combines cost these days I was disapointed with this machine,lacking power in tough conditions,poor threshing in spring wheat,time consuming serviceability,fire balls with flax straw,annoying little breakdowns too numerous to mention,lack of dealer pre-delivery and service,questionable quality of the machine itself,small fuel tank or bad fuel efficiency ,need I say more.The 860 was a better engineered machine for its time than some current equipment is today.Not intending to rain on anyones parade here,possible to have lemons in every color,too bad it had to cost 150K to find out, so it got traded for a deere for quite a few K more.Maybe we do get what we be paying forIJWishing OlD 750 success with your upgrade.
