????????????????????????????????

This 1994 Diedrich D-120 is mounted on a 1993 Ford F-800 and is being offered as a rebuild, repair, or parts candidate.

The truck itself runs, drives, and operates as it should, but the D-120’s John Deere deck engine is currently inoperable due to a seized engine. The seller reports that several of the major drilling components remain in usable condition, including the transmission, right-angle drive, rotary box, mast, main winch, and hydraulic pump.

For somebody who knows these rigs and is willing to put some work into one, there is a lot of machine here for the money.

????????????????????????????????????

- John Deere diesel deck engine
- Approximately 9,300 rig hours
- Approximately 20,000 lb pullback capacity
- Main winch – approximately 8,000 lb
- Auxiliary / tool winch – approximately 3,000 lb
- Wireline winch
- 200-gallon water tank
- Truck-mounted configuration
- Ford F-800 carrier

????????????????????????????????????

This rig needs work and is not currently operational as a drill.

Known condition items reported by the seller include:

- John Deere engine is seized
- Kelly bar is slightly bent
- Rotary box is reported good but needs new seals along the Kelly bar
- Transmission reported good
- Right-angle drive reported good
- Mast reported good
- Main line winch reported good
- Hydraulic pump reported good

The right-angle drive was reportedly replaced approximately 800 operating hours ago.

????????????????????

The rig is mounted on a 1993 Ford F-800.

According to the seller, the truck runs, drives, and operates as it should.

????????????????’???? ????????????????????????????????

The sale includes the truck-mounted Diedrich D-120 and installed equipment described above.

No additional tooling or spare parts are listed as included.

???????????????????????????? ????????????????????????????????????

This is the kind of machine that makes the most sense for a contractor, mechanic, or drilling company that can handle some of the work in-house.

The rig already has several major components that the seller reports as good, so the decision comes down to whether it makes sense to repair or replace the deck engine, address the Kelly bar and rotary seals, and bring the rest of the machine back into service.

It could also make sense as a donor machine for someone already running Diedrich equipment.

???????????????????????????????? ????????????????

This one is being represented exactly for what it is: a project rig.

The deck engine is seized, the Kelly needs attention, and there is work to do before it goes back to drilling. On the other hand, the truck runs and drives, and the seller reports that the transmission, right-angle drive, rotary box, mast, winches, and hydraulic pump are still good.

At $18,500, this could make sense for somebody who wants a D-120 platform to rebuild, needs a donor machine, or simply has the ability to do the work themselves.
