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”

1946 CJ-2A Shipshewana, IN $1500


Nick’s selling this trencher jeep.

“For sale is a 1946 Willys CJ2A I purchased in St. Louis. It was used as a true agrijeep, fitted with the early Jeep-A-Trench equipment. It has:

-Complete PTO system
-Complete gear-engagement system
-Trencher mount
-Coil helper springs
-Complete engine that turns free

I know where you can buy the correct style trencher. And on the South Bend Craigslist, there is a guy from Elkhart selling a trencher Jeep windshield. I located the trencher so I could build the Jeep for local tractor shows, but have too much going on. This Jeep deserves to be rescued and brought back to life… not parted out.”

Tractor w/ Auburn Trencher Hardinsburg, IN $6000

• CATEGORIES: Other 4x4s • TAGS: .

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.”

1957 CJ-5 w/Trencher Antwerp, OH $7,500


UPDATE: Price dropped to $7500 on eBay

“1957 Willys Jeep A Trench. I am the owner and have the title. This is one of the rarest things I have ever seen. It has an Auburn trencher attachment which later became Ditch Witch. This Jeep has been sitting in a pole barn for at least 10 years! I pulled and flushed the gas tank , blew out the fuel lines and cleaned the carb. It fires up and runs good! It will need some brake work! It was originally a baby blue color. It was repainted nearly 15 years ago. There was some patching done on the floor boards at that time. I’m sure they also patched it elsewhere. The paint job is fair for its age. It has some paint bubbles on the right rear quarter The interior is pretty nice and it shows 7770 original miles. Tires have excellent tread but are weather cracked. If you have an interest I urge you to come and look at it !! I have a lot of pictures. More than I can show here. I will gladly send you more. What a unique piece of equipment to own.. It is a 1957 and is not perfect. But would make a awesome restoration project. Sold as is needing TLC! Engine runs great!”
