PHD-1200, Digger Head Assembly

Description

The AG-GO PHD-1200 12 inch auger digger head is a complete ground engaging head for compatible post hole diggers. Its 12 inch cutting diameter is useful for larger fence posts, gate posts, poles, tree planting, and other projects that require more clearance than a 9 inch hole provides. The head connects to a compatible 2 3/8 inch outside diameter receiver through a cross bolt mounting system.

Hardened steel construction supports repeated agricultural, landscaping, property maintenance, and construction use. The PHD-1200 is the auger head and its ground engaging components; it is not a complete post hole digger, drive unit, boom, gearbox, hydraulic motor, or machine attachment. Buyers must verify the receiver, bolt alignment, available power, and operating clearance before ordering.

12 Inch Auger Digger Head with Replaceable Cutting Blades

A wider auger head removes more soil during each drilling cycle and creates additional clearance around an appropriately sized post, pole, or root ball. That can make the PHD-1200 useful for:

• Farm, pasture, livestock, and property line fencing
• Gate posts and agricultural structures
• Tree and large shrub planting
• Signposts, poles, and properly planned foundations
• Compatible tractor, three point, and skid steer digging systems

The larger diameter can require more power and torque than a smaller head. Soil density, moisture, clay content, roots, gravel, and buried obstructions all affect digging resistance. Confirm that the post hole digger, driveline or hydraulic system, carrier, and auger shaft are approved for the head and working conditions.

The PHD-1200 uses replaceable excavating blades, allowing worn cutting edges to be serviced without discarding the complete head. The PHD-200A replacement digger blade is the verified blade for both the PHD-1200 and PHD-900 heads. Each PHD-200A blade is sold individually, so inspect every blade and order the quantity needed for the repair.

The pilot point should also be inspected for rounding, chips, cracks, looseness, and mounting wear. The available information does not identify a specific replacement pilot tip model for the PHD-1200, so match its actual mounting design before ordering a separate point. Do not assume that every bolt on, threaded fish tail, or screw point tip fits this head.

Cross Bolt Receiver Fit, Installation, and Inspection

The PHD-1200 fits a compatible 2 3/8 inch outside diameter receiver base. Receiver diameter alone does not prove compatibility. The insertion depth, cross hole diameter, hole location, retaining bolt, surrounding clearance, and complete auger design must also match.

Before installation, shut down and secure the equipment so the auger and drive cannot move unexpectedly. Clean the receiver and inspect it for cracks, distortion, corrosion, elongated holes, or other damage. Slide the head onto the receiver until the holes align naturally, then install the specified cross bolt and retaining hardware. Do not force misaligned parts together, enlarge the holes, or substitute unidentified fasteners. Use the equipment manufacturer’s tightening and locking procedure.

PRO-Link’s post hole digger parts guide compares the PHD-1200 with available tips, blades, and the smaller PHD-900 9 inch auger head. The 9 inch model may be more suitable when the project does not require the wider opening produced by the PHD-1200.

Before drilling, contact 811 to request underground utility markings. Operators should also review Ohio State University’s post hole digger safety guidance, keep guards installed, keep bystanders away, and stop all movement before making adjustments or clearing obstructions.

Inspect the head, pilot point, blades, blade hardware, cross bolt, receiver, shaft, flighting, driveline, gearbox or hydraulic motor, and guards before operation. Replace loose, cracked, bent, chipped, or badly worn components. The PHD-1200 is covered by PRO-Link’s one year limited warranty against manufacturer’s defects, subject to the complete terms.

Questions & Answers

What size hole does the PHD-1200 digger head produce?

The PHD-1200 has a 12 inch digging diameter. Actual hole condition and finished dimensions can vary with soil, operating technique, component wear, and ground disturbance.

What receiver size fits the PHD-1200?

It fits a compatible 2 3/8 inch outside diameter cross bolt receiver base. Confirm the insertion depth, cross hole size and location, retaining bolt, and operating clearance before installation.

Can the cutting blades be replaced?

Yes. The PHD-200A is the verified replacement excavating blade for this head and is sold individually with its applicable mounting hardware.
