The first 3 or 4 071s were built on Terex tractor carriers. There was then a bunch built on tank undercarriges. We then went to a fabricated carrier using the same cross drive, trans, bogies and tracks as the tank carriers but were fabricated from 3/8 plate and not 1 1/4" armor plate as the tank carriers were. I worked on almost every 071 that came out of the Nanaimo plant and delivered a very large number of them. Thanks for posting all the pictures of them. Glad to see so many still out there especially the really old ones. I would really like to know what the machine in the background in the 4th pic post 1069 and 1st pic post 1071. I'm wondering if is the one and only "1400" that we built that went to Yardstick Contracting in Sparwood. I delivered it and went back to work on it only twice and then lost track of it. Any info would be much appreciated. Regards D.D.


In 2003/2004 I spent alot of time working in the Northwest area of Oregon. Florence to Astoria as Weyerhaeuser had just aquired all that Willamette ground out there.
Stan Baller was logging a sale way up in the back-end of the Trask River country (20 or so miles East of Tillamook) using an early Madill 071/Boman carriage combination and loading with a Madill 2800B log loader. The Trask River drainage was full of active logging operations at the time and it was common for 7 or 8 yarders to be working up one road system. Lots of log trucks and all the time going too fast. That Trask road isnt the best for truck traffic either!
Many of the earlier Madill 071's were mounted on Terex 82-30 and 82-40 crawler setups. This was great due to the fact that a transmission (with reverse even) was standard on the Terex and the Madill tank mounts usually only had torque converters. The Terex machines had a real yarding speed, travel speed, and mobility advantage over the tank machines.
The small yarder in the background also catched my interest, here's the same machine pictured on the brochure cover!
Is the 009 trlr mtd the same as you published pictures of earlier? Did you get some serial number off that one? It's also interesting with serials from both of the 071's.
