It was sitting under a shade tree just outside a 4-H exhibit building at the fairgrounds in Jackson County, Ind. The Allis-Chalmers D10 looked like it should’ve been parked in a tent, in an Allis-Chalmers dealer’s exhibit, ready for delivery. Without a doubt, it looked showroom-new.

Perhaps 60 years ago, there were Allis-Chalmers tractors on display at the iconic Jackson County Fair. Today, the D Series is long discontinued. In fact, Allis-Chalmers no longer exists itself, having hit hard financial times in the early 1980s. For a while, it operated as Agco-Allis, and the brand was eventually absorbed into Agco, the third-largest tractor maker worldwide. Less than 20% of Agco’s tractors are sold in the U.S.

The showroom new-appearing D10 Series II tractor pictured here belongs to the Klinge family of Crothersville, Ind. According to tractordata.com, Allis-Chalmers began promoting Series II tractors in the D Series in 1963. The D Series was produced from 1959 through 1967. The D10 is often lumped together with its sister, the D12. Both were rated at 31 engine horsepower.

The D10 featured either a 2.3- or 2.4-liter, four-cylinder Allis-Chalmers engine. The D-10 tested at nearly 29 horsepower at the drawbar and 33.5 PTO horsepower, giving it good power for such a small tractor. It laid the groundwork for compact utility tractors popular today.

Earlier models came with the Allis-Chalmers snap-coupler hitch system. Hydraulics were live, with an option for one or two valves. List price in 1967, if you found one sitting in a display at a county fair, was $3,400.
