The history of the Allis Chalmers tractor dates back to 1914, and for 70 years, the company released recognizable and well-known pieces of farm equipment. A German company purchased Allis Chalmers in 1984 and began releasing tractors under different name brands. Older and antique Allis Chalmers tractors are sometimes quite valuable, but you must identify the type of tractor and authenticate it.
Look at the tractor for any signs of an orange color. The orange shade was a trademark of the Allis Chalmers company and they used it on a large portion of the body. Even if someone repainted the piece or it faded due to sun damage, you should still see some traces of orange.

Check the nose of the tractor for the Allis Chalmers name. The company typically used a white or yellow label with the company name in black. You may find a black label with white lettering, and this can be either on the side or front of the tractor.
Write down the serial number, if you find one. Look for the serial number on an Allis Chalmers tractor on a black label above the company name. This number may have letters, which indicate the model of tractor. Check the front nose for the number if it's not on the side.
Compare the model number or serial number you find against those listed in value guides or websites with information on the company. See References for websites that offer full-color photographs of different tractors and a short history on those models.
List photographs of your tractor on a website where others can view the photos and offer feedback or help in identifying the manufacturer of the tractor, the date of release and any other helpful information known. (See References.)
Consider hiring an expert appraiser to examine your tractor. Not only will you learn if it’s an authentic Allis Chalmers tractor, but also its history and current value.
