Yep, prior to that acquisition Allis Chalmers was using Detroit engines to power their crawler tractors. When they bought out Buda in '53 they quit making the HD-5 (Detroit powered) and started making the HD-6 with the Buda engine. The early HD-6 models had the D-344 4 cylinder, 57 HP. Later models had the 6000 series 4 cyl with HP that ranged from 69 to 75 HP. Back in my former lifetime I operated a drill rig mounted on a HD-6E with the 6000 series. Stout little engine that had really good low end HP and torque, and had a good sound tone to it as well.It's really in good condition, Allen the owner ran it a couple of years ago. AC bought Buda out in 1953.
Nope, that was my helper Chris Camacho, came in every Monday morning on time with a hangover and at least one black eye where he'd get in bar fights over the weekend. True story. Asked me one day if I had some aspirin, all I had was Goody Powders. He took two, after that day he wanted my whole box as they didn't sell them in Massachusetts.Thanks for the info Willie, so which one are you in that photo? I bet the one on the right who looks like he's the one working
