“I take cash or PayPal. Firm on price. First with payment takes it. Located in Shipshewana, IN. 1959 Willys Jeep CJ5 with Auburn Jeep-A-Trench. AgriJeeps were a standard CJ with aftermarket farm equipment, making a dual-purpose vehicle.

This is one of very few operational trencher Jeeps left. I can send you a video of it trenching my backyard. This particular trencher is the latest, greatest version available for the Jeep. It sits inside the bed, rather than hanging off the back. It removes quite a bit of stress from the chassis and body. Hydraulic boom raise/lower and gear-driven chain. Has a new heavy duty clutch kit, fuel tank, fuel pump, lines. Tires all hold air. Runs and drives nice.

“1952 Willys CJ3A Auburn Jeep-a-Trench Trencher Jeep.
Project – must sell to save this iron. I will consider fair offers. Early Auburn Trencher wheel drive, on a 1952 Willys CJ3A.
No Title. Low miles. NE Ohio. Akron / Canton Area. This Trencher was used to dig irrigation ditches on a golf course in Northern Ohio. It was sitting outdoors when I saved it.
Frame is in great shape. Leaf springs are ok. Body is pretty good (my opinion), No filler. Could use new front floor of course. Half cab top bows – no canvas, no door frames, Monarch Governor with handle and cable. Motor and Transmission are locked, I disconnected the drive shaft to roll it. I removed all brake drums also, found one rear hub was cracked so I replaced both rears hubs. Green narrow 16″ jeep wheels go with it, see last picture.”

Auburn Machine Works Trencher Patent

• CATEGORIES: Features • TAGS: , .

There are some great illustrations that accompanied this patent filed August 15, 1950, by Friedrich Schmidt on behalf of Auburn Machine Works.

1955 CJ-5 Trencher San Antonio, TX **SOLD**


UPDATE: **SOLD** Was $2000.

Jeep lacks brakes and the trencher needs some work. Has a Meyer half cab and a plow up front.


“Here is one of the Holy Grails for the Jeep Collector. The “Jeep-A-Trench.”

I recently uncovered this Jeep from a farm in Winters Texas. The rancher had owned the Jeep since the 1960’s or so. It has the ultra rare Jeep-A-Trench rear end and the front mounted Dozer blade. It is also outfitted with the Arctic top and hard doors. All the glass is good and I even have the back cab glass thats in perfect shape. The seal just dried up.

The Jeep has no found rust through, been in Texas since new. Even the under seat tool box is solid. The Jeep was paint industrial yellow likely when the gear was installed. But the factory original was that nice turquoisey blue.

The Jeep runs and drives but currently has no brakes. The front blade still works and automatic raises and lowers from inside cab. The rear Trencher is all there minus needing a new drive chain and slide on dual sprocket. The unit is otherwise 100% complete.

The Jeep has four new tires and a new battery. I had never even seen one of these Jeeps. There’s a brass data plate that states….”Jeep-A-Trench” on the Jeep. Super cool find.”

Auburn Trencher Columbia, SC **SOLD**

Mike spotted this trencher.

“1960s Auburn Trencher that will cut 12″ wide and up to 10′. Bracket on back will attach to Willys Jeep. This is not a show piece and will need some work to get it functional, but all the pieces are there. There is an awful lot of steel so it could be worth scrapping. We can work out delivery if needed.”

1964 CJ-5 Trencher Buffalo, NY No Price



Seller believes it to be a Tux Park.

“For sale I have I believe a 1964 willys cj5 tuxedo park with 15000 original mileage. This was purchased from the original owner. I had this running a couple years ago it ran great the dauntless v6 ran great and it drove good. The trencher worked just as it should. It is equipped with a half cab that is in great shape. There is some small spots of surface rust here or there but it Is rock solid no rot. The trencher has been on since day one I have the tailgate that was removed to install it. Along with the jeep I have a ton of spare trencher parts there is almost enough to build a second trencher minus the boom. I have no clue what this is worth I don’t want to give it away if interested message me and we can talk.”

The Story of the Auburn Jeep-A-Trench

• CATEGORIES: Advertising & Brochures, Features • TAGS: .

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 ….
