This was published around 1950. It’s less story and more marketing, but still interesting. The argument that the trencher doesn’t affect the roadability of the jeep might be a stretch ….

1968? CJ-5 w/ Auburn Trencher Storrs, CT **SOLD**
UPDATE: **SOLD** Was $2800.
(12/04/2017) Ted’s selling this CJ-5. I estimate it to be around mid 1968, but that’s just a guess based on the serial number.
“For sale late sixties CJ5 Auburn Jeep A Trench . Starts, runs good and drives , clutch feels good , no brakes . Body’s kinda rough but frame looks pretty good . Havent had a chance to go over it well to check everything but seems to be pretty complete , missing one of the augers. PTO engages and shaft spins . Not very familiar with these units so will try my best to answer any questions. Looks complete enough to restore or get going and use as is, or would be a great parts donor for another Auburn Trencher unit. Front counter weight there ,as is the creeper gear , pto assembly, Fhead Governor , overload springs ( Canfields or Koenigs ?) etc”

Trencher’s First Appearance?
This photo from the October 1954 issue of Kaiser Willys News got me thinking. Anyone know when the first jeep trenchers were manufactured?

Tractor w/ Auburn Trencher Hardinsburg, IN $6000
Glenn spotted this Auburn trencher on the back of a tractor.
“International 2400 gas tractor with Auburn mounted trencher and Auburn mounted dozer blade. This is a one of a kind machine. Google it, Auburn made trenchers for tractors and Willys Jeeps from the 40s through the 80s. Parts are still available from a dealer in Virginia. I got this given to me by the original owner. I brought it home, and got it running. It has been sitting for about 4 years. Last time it ran, when the engine got warmed up, it died. Let it cool, it would run again. Easy electrical fix, I just have no need for the tractor. It is a cool piece to look at! Auburn split the tractor and mated the gear transmission with a hydraulic one. It still runs ans drives like a tractor, but when you engage the Auburn transmission and pto for trencher, it takes over. 98 ACTUAL HOURS. I know the complete history on the machine. It has a 5″ trencher on it. Blade works all the way. It really is handy, I just have no need for it. Feel free to call with any questions. Good for collecting or for use!!! I am asking $6000 obo. Make me an offer, I need the barn space! I can load it on your trailer.”

I have extra chain pieces, and the under Jeep components. Please call Denny for more information. I have collected Jeeps, and at my age I do not foresee doing anything more with them.
