The Haugen Dakota skid steer post driver is a hydraulic impact post driver capable of driving wood and steel posts without pre-drilling. Available in two models: PD-1600 (drives posts up to 7.125", 500–900 BPM) and PD-1850 (drives posts up to 8.25", 400–800 BPM, 1,325 lbs). Both feature plumb bob chain, depth gauge, built-in post puller chain, and 3/4" heavy-duty mounting plate. Optional accessories include hydraulic tilt, height extension, auger drill, concrete chisel, moil point tools, and 12" dome/flat head tools (PD-1850). Universal Quick Attach. Made in USA with a 1-year warranty.

The Dakota driver operates on 1 aux hydraulic circuit. Check your skid steer's GPM and PSI spec against the model's hydraulic requirements before ordering. PD-1850 at 1,325 lbs — verify machine ROC is adequate at the loader's rated load center before use.
Compatible with skid steer loaders and compact track loaders with Universal Quick Attach:
| Bobcat | Caterpillar | John Deere | Case |
| New Holland | Takeuchi | Kubota | Gehl |
Verify auxiliary hydraulic flow rate (GPM) and back-pressure requirements match your machine's aux circuit capabilities before operating.

Q: What is the difference between PD-1600 and PD-1850?
The PD-1600 drives posts up to 7.125" in diameter at 500-900 BPM. The PD-1850 drives posts up to 8.25" in diameter at 400-800 BPM and weighs 1,325 lbs. The PD-1850 has a higher capacity for larger posts (such as 8" wood corner posts or large sign posts) and adds the optional 12" dome or flat head tool for extra-large post applications. Choose the PD-1600 for most farm and light commercial fence work; choose PD-1850 for large structural posts. |
|
Q: Can the Dakota driver be used as a concrete breaker?
Yes — both the PD-1600 and PD-1850 can be fitted with optional concrete chisel and moil point tools to break light concrete and rock. This is a secondary application between post driving jobs. The PD-1600 can also be ordered with a horizontal breaker mount option for dedicated breaking work. The impact energy from the driver's hydraulic mechanism translates effectively to chisel-type concrete breaking. |
|
Q: What is the purpose of the optional hydraulic tilt?
The hydraulic tilt option (available on PD-1600 and PD-1850) allows the post driver to be angled from the cab without a helper, enabling fence posts to be driven on slopes and hillsides where the ground is not level. Without tilt, the post driver head hangs vertically. On sloped terrain, the operator uses hydraulic tilt to angle the driver along the slope, keeping the post aligned with gravity on the slope rather than with absolute vertical. |
|
Q: Does the Dakota driver work on hard clay or rocky soil?
Yes, but performance varies. In hard clay, the impact mechanism provides excellent penetration. In light caliche or gravel, it still performs well. In hard rock or highly compacted caliche, augering may still be required to start the hole. Optional moil point and rock spike accessories help in harder soils by fracturing the top layer before full post driving begins. Contact Haugen at 877-580-6218 for guidance on your specific soil conditions. |
|
Q: What hydraulic flow does the Dakota driver require?
The Dakota driver is a standard-flow hydraulic attachment. Exact GPM requirements depend on the model. Most mid-size skid steers (Bobcat S740, Cat 242D, JD 320) have sufficient aux flow. If you have an older or compact skid steer with low aux flow, verify with Haugen before ordering. The Dakota driver is specifically designed for ease of operation and rental applications, so it is engineered to work on a wide range of host machines. |
