PHD-900 9 Inch Auger Digger Head Assembly

Description

For fence rows, gates, and planting jobs where a 12 inch opening would remove more soil than needed, the AG-GO PHD-900 9 inch auger digger head provides a smaller cutting diameter in a serviceable assembly. It is designed for compatible post hole diggers with a 2 3/8 inch outside diameter cross-bolt receiver base. The head can be used for property-maintenance work when the receiver, drive system, and carrier are properly matched.

Hardened steel construction supports repeated ground contact in compacted soil, clay, and other demanding conditions. The PHD-900 is the working digger head; it is not a complete tractor attachment, auger shaft, boom, gearbox, hydraulic motor, or driveline. Equipment power, operating clearance, receiver measurements, and all mounting details must be confirmed before installation.

9 Inch Auger Digger Head for Posts and Planting

The 9 inch cutting diameter suits many common projects that need room around a post or root ball without creating the broader opening produced by the 12 inch PHD-1200. Common applications include:

• Farm, pasture, and livestock fencing
• Gate, sign, and mailbox posts
• Tree and large-shrub planting
• Property boundaries and landscape projects
• Compatible tractor, three-point, and skid steer auger systems

Hole diameter should be selected for the job rather than by equipment category alone. The post or planting material must fit inside the opening with enough room for the required backfill or installation method. Soil conditions also matter. Packed clay, dry ground, roots, gravel, buried debris, and moisture can change the power required and the quality of the finished hole.

Replaceable excavating blades allow worn cutting edges to be serviced while a sound head remains in use. The PHD-200A replacement digger blade is the verified blade for the PHD-900. It is made from solid hardened steel with a published hardness of 36–38 HRC and is sold individually with one 1/2 inch bolt and locking nut. Inspect every blade before deciding how many replacements are needed.

The excavating blades and center pilot point perform different jobs. The pilot point makes the first ground contact and helps establish the hole, while the blades cut and move soil across the head’s working diameter. The available product information does not identify a specific replacement pilot-tip model for the PHD-900, so its actual mounting design must be verified separately.

Receiver Fit, Cross-Bolt Installation, and Safe Operation

The PHD-900 fits a compatible 2 3/8 inch outside diameter cross-bolt receiver. Diameter alone does not confirm fit. Measure an unworn area and compare the insertion depth, cross-hole size and location, retaining hardware, and surrounding clearance. PRO-Link’s post hole digger parts guide provides additional identification and comparison guidance.

Before installation, lower and support the equipment, shut off its power source, remove the key, and wait for all movement to stop. Clean and inspect the receiver for cracks, distortion, severe corrosion, or elongated holes. Slide the head onto the receiver until the openings align naturally, then install the specified cross bolt and retaining hardware. Do not force unmatched components together, enlarge the holes, or substitute unidentified fasteners.

Inspect the head, blades, pilot point, cross bolt, receiver, shaft, flighting, guards, gearbox or hydraulic drive, and machine connection before drilling. For projects needing a wider opening, compare the PHD-1200 12 inch auger digger head before ordering.

Contact 811 before beginning any digging project so participating utilities can mark buried lines. Operators using tractor-powered equipment should also review Penn State Extension’s PTO safety guidance and follow the equipment manufacturer’s manual. The PHD-900 is covered by PRO-Link’s one year limited warranty against manufacturer’s defects, subject to the complete terms.

Questions & Answers

What receiver size fits the PHD-900?

The head fits a compatible 2 3/8 inch outside diameter cross-bolt receiver base. Cross-hole position, bolt size, insertion depth, and clearance must also match.

Which replacement blade fits this digger head?

The PHD-200A is the verified excavating blade for the PHD-900. Each blade is sold individually with one 1/2 inch bolt and locking nut.

Should I choose the PHD-900 or PHD-1200?

Choose the PHD-900 when a 9 inch hole provides the required post or planting clearance. Select the PHD-1200 when the project and equipment call for a wider 12 inch opening.
