What is the difference? Made in different places? Is one better? Or are they the same?

It's already been explained pretty well below, but i just want to add, Agco Allis (now Agco corp.) has sold/built some very good tractors. I have had very good service out of the (2) newer tractors that i have. The models i have are simple, and very easy to work on, just like some of the old ones, but with modern features. I guess the answer has already been said, depends on wether you like old, or new? I like both. Robert

As of December 1985 the Allis Chalmers tractor died, many 8000 series were sold thru the DA Dealer to get rid of stock. Nothing in a Deutz Allis after the orange color left is AC. The factories were closed and some demolished in West Allis. The Harvey(engine works) lasted a bit longer. The true Deutz Allis was a Deutz engined White drivetrain, with European cab and tin design. The implements were farmed out to several manufactures to be built on contract. The Gleaner was the only survivor to the DEUTZ DESTRUCTION with a Deutz engine. For most cases Deutz FLUSHED or BURNED over 100 years of technology that was at its finest. Deutz proved to be much worse managers than the AC team. When Deutz started to fall, Deutz NA execs. and a few from the Bankrupt IH pooled their resources and started AGCO. They were well experienced in the Ag & Business industry. It took a little time to shed the Deutz hard feelings of the AC group but many have returned to the Orange machinery for its returned quality and customer satisfaction. AGCO has to have something going right, they are buying troubled companies and breathing NEW LIFE into them with quite a bit of success. Especially in the poor AG economy since they were started just over 10 years ago. Personally I will own an AC that was years ahead in technology over the Deutz Allis that fell out of the market in 5 years. JMHO

Dano is not that far off. Allis Chalmers made tractors in the 1920-30-40-50 era. By 1950 they were doing great and selling quite a few. The WD45, C and B tractors were from the 1940-50 era. In the early 1960 they redesigned and upadated everyting and started making the D14-D15-D17, then the bigger D19 and D21, around 100 HP. Times got tought in the mid 1970s and by 1980 financial troubles were too far gone. Allis Chalmers sold the Construction Division to Fiat (thus Fiat Allis dozers) and later the farm tractor division to German Deutz, thus (Deutz Allis) They started putting Deutz diesel engines in the tractors and painting things green, etc. Later Deutz sold to AGCO, thus AGCO Allis for a while, now AGCO. All the same company, but the tractors continue to change. Like saying which is better a 1950 Chevy or a 1990 Chevy? Depends on what you want, new power and top$$$ or old time simplicity, low cost and over design equipment. Most of us prefer the older stuff. I consider the D series the last Allis tractors, personally.

Just wondered because i picked up a service manual for the 7010 and didn't know what it was. I am not familiar with A-C, I have a MF.

Deutz married Allis's daughter and Chalmers up an' died. Hence Deutz-Allis. I think something like what happened to Farmalls and Case-International too. Sorry about that, but I could help it. Hope you appreciate the humor.
