That's just what it is and there is a G engine to power the combine down on the right where you can't see. I believe there were 5 built to government specs during WWII. There are at least 2 known to exist, possibly 3. John Mrotek owned one and I thought I read one was in England.

I believe Allis Chalmers only supplied the parts. These were built by universitys if I remember correctly. The combine is ran by a Briggs or maybe Wisconsin ? The G just runs the drive wheels. ------------- Randy Freshour,Member Indiana AC Partners, http://www.rumelyallis.com" rel="nofollow - http://www.rumelyallis.com |

I thought I saw a picture of one with a G hood down on the combine drive, musta been in my head. Here is John Mrotek's old combine from the other side and it appears to have a Wis engine. Don't know if the link worked. http://www.aumannauctions.com/index.php?subp=1&sct=2&pg=ap&pid=1212&ap_sub=fp - http://www.aumannauctions.com/index.php?subp=1&sct=2&pg=ap&pid=1212&ap_sub=fp One the Aumann action page it mentions John purchased this combine from the University of Tn. I never heard anything about these combines being built buy Universities before. I would like to hear some other input on this.

Well the picture link takes you to the picture page. Go to the fifth to the last picture and you can see the engine on the side. Here is a story about who built them and where. Stan Wolf's Allis-Chalmers SP-40 self-propelled combine was born in 1940 of a perceived wartime necessity to decrease the country's reliance on foreign markets for strategic grains. In this particular case, the War Department was interested in developing varieties of Rape (Brassica napus), an annual plant in the cabbage family, for its seed oil, which is a key ingredient in synthetic rubber. As part of that effort, the Army Corps of Engineers was handed the task of developing a self-propelled test-plot combine, and they chose to work with Allis-Chalmers on the project. Essentially, the Model SP-40 consists of a Model 40 pull-type combine mounted on a small truck chassis. The wheels and tires are standard military issue, complete with brake drums (but no brake shoes). An Allis-Chalmers Model G rear-engine tractor is mounted above the combine and powers the drive wheels and hydraulic system. A separate, air-cooled Wisconsin engine was mounted low and on the side of the unit to power the harvesting and threshing components. The operator's station was high above the cutter, which offered excellent crop visibility, but with its narrow 40-inch width, the machine can be easily upset. Stan's Model SP-40 is one of five built, and one of three known to survive. This particular unit was assembled at the Letterkenny Army Base near Chambersburg, Pa. 'I obtained it about 20 years ago after it had been stored at the base for over 40 years,' Stan says. 'It was painted army khaki, but I chose Allis orange when I restored it.' One of the other two SP-40s is in a museum in Oxford, U.K. The other is in the hands of a private collector ------------- http://www.ae-ta.com" rel="nofollow - http://www.ae-ta.com Lena 1935 WC12xxx, Willie 1951 CA6xx Dad bought new, 1954WD45 PS, 1960 D17 NF |

Maybe that combine could be called an Allis Chambersburg. ------------- http://www.ae-ta.com" rel="nofollow - http://www.ae-ta.com Lena 1935 WC12xxx, Willie 1951 CA6xx Dad bought new, 1954WD45 PS, 1960 D17 NF |

Yep, built by the Corp of Engineers. I knew I remembered something about the University being involved, couldn't remember the whole story. Ken Eder in North Carolina owns John's now. I thought someone on here showed a picture of a forth one up in Michigan or Minnesota (Canada ?) ? It is sitting right next to the road but is really rough. ------------- Randy Freshour,Member Indiana AC Partners, http://www.rumelyallis.com" rel="nofollow - http://www.rumelyallis.com |

The photo posted above is of John Mrotek's combine at his sale where it sold to a North Carolina buyer for $25000. There is an article in the Winter 2008 issue of O.A.N. discussing these self propelled 40 combines. It lists a Stanley Wolf of Pennsylvania as owner of one and he displayed it at Marion, Ohio in 1991. It was painted military green when he bought it. In the article there's a photo of a 40 S.P. combine. Whether it's belongs to S. Wolf, I don't know but the picture shows what appears to be 2 Wisconsin motors mounted on either side of the combine. There is no model G engine mounted on top as in the above photo. Actually that's where the operator sits (further back) on this other machine. The O.A.N. article also states that one machine is in England, believed to be a conversion done by the N.I.A.B. (a plant research organization) in Cambridge, U.K. Also I saved a pic from a clearing sale advert. It appears to be a similar conversion. Stupid me didn't save any of the details, though.

Here are some photos of John Mrotek's Self Propelled Combine miniature replica at Dale's show last year.Talked to John for a few minutes,very nice man.He even took the plastic cover off so I could get a few pics.
Should have got a little closer and got some better pics.Need to slow down at these events and take full advantage of these events. ------------- You only need to know 3 things to be a plumber;Crap rolls down hill,Hot is on the left and Don't bite your fingernails 1964 D-17 SIV 3 Pt.WF,1964 D-15 Ser II 3pt.WF ,1960 D-17 SI NF,1956 WD 45 WF. |

| One stupid question.......since the 'G' didn't come out till 1948, how could this combine have been built during WWII???? |

Good question. I would guess they were in development during the war?? but weren't put into production till material was available. ------------- http://www.ae-ta.com" rel="nofollow - http://www.ae-ta.com Lena 1935 WC12xxx, Willie 1951 CA6xx Dad bought new, 1954WD45 PS, 1960 D17 NF |
