1938 A-C Power Horse

I did not know these existed until yesterday. Now, I have decided that my life will not be complete until I have one.

That is a neat Allis piece. Probably not many around?? Good luck!

To be accurate, only the ‘B’ engine was made by Allis Chalmers. The rest was by the Harris Power Horse Company.

Here’s an article on it; from “Farm Collector”:

Still super cool!

As I understand it they operate like a skid steer where you apply power to one side or the other to steer . Is this thinking correct ? Also were these the predecessor to the original bobcat ? Did Melroe buy the rights to produce ?

The Albert & Bond Bonham Patent
led to the creation of
the Prototype (Trigger).

This Prototype led to the
Eimco Power Horse (Miss Mavis).

The Eimco Power Horse led
to the Allis Chalmers model
which is focus of this Topic.

Following the end of WWII,
AC sold the design to
Harris Manufacturing.

I was just with the Staggs at Hutchison this weekend, where we discussed the need to write a proper correct history of this special tractor. I spent about a half day talking to Albert Bonham's son, Stanley a few weeks before he died. According to Stanley; Bert & Uncle Bond made two prototypes with Hercules engines in about 1938. They then entered some type of joint venture with Eimco to produce the first Power Horses using A-C 125 engines and transmission gears common to the AC-B. They also used A-C hoods & radiators. Their tractors were painted many different colors, but none were Persian Orange. Then right before WWll they sold the rights to the Power Horse to A-C. At this time A-C moved Bert & his family to West Allis where they employed Bert as a consultant to the project. According to Stanley, A-C produced two prototypes before abandoning the project & giving the rights back to the Bonhams at the end of the war. Bert moved his family back to Utah & commenced building more tractors for a short period of time before selling the design and rights to the Harris Company out of Stockton California. I'm really sorry that I didn't have the foresight to record this meeting with Stanley.
