FEATURES

• HONDA GXV390 13 HP 4-STROKE ENGINE: Delivers dependable, commercial-grade power for high-performance hole digging. Its efficient fuel use and consistent output mean fewer interruptions and smoother operation on every job.
• EXCLUSIVE SNAP-LOK AUGER STORAGE SYSTEM: Tilt the auger out of the way with a single motion, making transitions between holes faster and easier. This saves time and effort while keeping your workflow moving.
• LARGE TIRES FOR ON-SITE MANEUVERABILITY: Navigate rough or uneven ground with ease. These tires provide stability and smooth handling, so you can push or pull the machine by hand without strain.
• MULTI-PURPOSE POW-R-PORT: Powers additional hydraulic tools directly from the machine, giving you maximum jobsite versatility without bringing extra equipment.
• AUGER SIDE TILT FOR SLOPED TERRAIN: Adjusts up to 20 degrees for vertical digging on uneven surfaces. Eliminate the need to reposition the entire unit, saving time and improving accuracy on hillsides or angled ground.
• LARGE HYDRAULIC FLUID RESERVOIR: Maintains cool fluid temperatures during extended operation without the need for an auxiliary cooler. Keeps the machine running longer and reduces downtime.
• INTEGRAL HYDRAULIC PUMP PRESSURE RELIEF VALVE: Automatically detects hydraulic overloads to prevent damage and extend equipment life. Protects your investment while reducing repair and maintenance costs.
• 276 FT LBS OF DIGGING TORQUE: Provides outstanding torque to break through compacted, rocky, or clay-heavy soils. Ensures faster digging with less wear on the auger and engine.
• CENTER-BALANCED DESIGN: Keeps the auger in a neutral, stable position to minimize physical effort. Easier handling and less operator fatigue throughout long workdays.
• WIDE STANCE FOR STABLE TOWING: Tows safely at highway speeds—even on curves or sudden stops. No need for a trailer, saving transport time and costs.
