Is This Right For You?
✅ Buy if…
- You drive large wood fence posts, landscape timbers, or round posts into hard or rocky ground
- Farm fencing, ranch infrastructure, or commercial property perimeter fencing where post size is large
- Impact force matters more than speed — heavy drivers hit harder for difficult soils and large post diameters
⛔ Skip if…
- You're installing standard T-posts in soft ground — a standard or vibratory driver is faster and cheaper
- Weight is a concern on your machine — heavy-duty drivers add significant weight to the front
🔍 Also consider…
- Standard hydraulic post driver for T-posts and normal fence post work
- Vibratory post driver for faster installation in soft-to-medium soils
🔧 Machine Compatibility
Compatible with all skid steer brands and compact track loaders via universal SSQA quick attach. Mid-frame machines (S450–S650 class) are the most common fit.

Care & Maintenance
- Grease all impact guide bushings and driver head fittings before every use — the impact energy transmits through these components on every blow
- Inspect driver cap or guide inserts after every session — worn or cracked guide caps split wood posts and bend T-posts, which then jam inside the driver tube
- Check hydraulic hose connections and the pressure accumulator (if equipped) before each use
- After work in clay or mud, clean the guide tube interior to prevent soil compaction that restricts post insertion and causes the posts to jam
- Inspect the impact guide rod monthly for scoring or deformation — a scored rod causes erratic impact energy and accelerated bushing wear
How to Connect
- Attach post driver using Bob-Tach
- Connect single-acting hydraulic circuit for hammer
- Set machine to single-action mode if available
- Test one light hammer stroke before driving at full force
⚠ Safety NotePost drivers use single-direction hydraulic flow. Keep hands clear of hammer mechanism.
