Anyone on the forum still own/operate a New idea Uni-System equipped with an AC engine? When I was a kid, our neighbors had one with a straight pipe exhaust AC 3500 670T?? Dad hired them to cut corn silage. I remember hauling box wagons to&from field. Never difficult to locate it in the field. Chopper always had a black exhaust plume & was loud. Powerful though! I think it chopped 3-30 rows? I’ve heard & read that AVCO used numerous makes of engines to power the Uni-System. Never was around one setup for combine. How’d they do with those attachment? |

I don't have anything anymore, but dad always talked about the old min-mo uniharvester that he use to have. I thought it was neat of the idea that you changed whole units on a uni-tractor. I know these are what led up the new idea system. ------------- On the farm: Agco Allis 9695, 7060, 7010, R66, Farmall H, and Farmall F20 (Great Grandpa's) |

Worked at Heathercrest Farms years ago, had a Uni-system, combine w/ 13 ft grain, 4-wide corn, forage harvester w/ hay head, and 3-row vari-width for corn silage. A/C engine, yes could always know where it was. Combine did pretty good, never much out the rear. The colder the weather the better it worked. Chopping hay, the IH 856 pulling the Gehl 800 would outpace the Uni., corn the same way, but the 3 row was only utilized to open fields, most fields were to big to make it end to end when chopping 3 rows ------------- I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science. |

Minneapolis Moline came out with that unit. I once used one with a 2 row corn picker on it, in the early 60's. ------------- 917 H, '48 G, '65 D-10 series III "Allis Express" |

I worked at New Idea nearly 20 years in the Coldwater plant hiring in on 8/26/65. That Uni System got me a job. It's been a long time but I believe the first ones had a small 6 cylinder Chevy engine that easily overheated. |

In the early and mid 70's I worked for an Allis Chalmers dealer that also handled New Idea. We had a lot of seed corn grown in this area so the Uni's with a picker were pretty popular around here. From what I remember the early New Idea Uni's used a Chevy 292 inline 6, then they switched to a GMC V6 in gas or diesel. Then in the next newer models they started using the Allis 426 (3500 model???) and they had a Perkins option also. There may of been another engine option available, but if there was we never sold any. I lost track of models after that as I started my own shop in 1976 and was not around the new ones. The salesman that sold these joked "every time we sell another Uni we had to add another man to the shop" so reliability was not their strong point. I hated working on them as it seems your were working on your head between the implement and the power unit or were pulling the implement off to work on the "hidden" side of the implement or the power unit. |

We still own a 803a, it has the 670I in it, the 803c came with the Cummins, the earlier models used the 3500 Allis. We used it for chopping corn, 3 row 30 , it chopped corn quite well , it was a nightmare to work on. Ours smoked very little after installing their last model throat, modified by me some so the corn fed in smoothly and evenly. ------------- 2-8050 1-7080 6080 D-19 modelE & A 7040 R50 |

Thanks for sharing. Since I posted this topic, I’ve also been internet researching these Uni-Systems. Did your Dad’s 702 have the GM401 6.6L V6 gas engine? If so, it’s spark plugs & wires were installed on the inner banks of its heads. 1966 era? How many bushel was it’s graintank? |

| Must of been the gm engine because I remember a foul mood when he needed to tune it up. Can't remember how big the bin was but I do remember it wasn't very big. Had to have a wagon at both ends of the field. We were grinding the corn for cow feed so dad had pulled the screens to get more cob. I really think it was a good machine but I was a teenager back then |
