They are engineered for bunkers up to 38 metres wide, with optional 15 m, 18 m, and 21 m barrels to reduce resets and improve site flow.

Depending on configuration:

• PTO Single 15″: up to 340 t/hr
• Self‑Propelled: up to 380 t/hr
• PTO Dual 15″: up to 650 t/hr

These high continuous capacities are designed to match fast harvest pace and keep trucks cycling efficiently.

Grainline Bunker Augers are designed for rapid parallel repositioning:

• PTO units: typically < 2 minutes
• Self‑Propelled units: typically < 1 minute

This minimises downtime between loads and maintains constant flow.

A full‑width, low‑profile drive‑over hopper with triple flight intake provides smooth, even grain flow and safer, more forgiving truck approach angles. Hydraulic folding ramps further improve access and driver confidence.

An electric directional swivel spout provides accurate placement, helping create a clean, consistent bunker profile while reducing rework.

Three configurations allow buyers to match site needs and existing assets:

• PTO Single 15″ – cost‑effective; uses existing 180–200 hp tractors
• Self‑Propelled – 182 hp diesel engine with full hydraulic integration
• PTO Dual 15″ – requires ~350 hp tractor; designed for maximum throughput

Ideal for co‑ops, bulk receival sites, and large growers filling temporary bunkers with high truck cadence. Perfect for operations that require fast turnaround, minimal dead time, and consistent pile shaping.

The Bunker Auger range includes a 12‑month warranty and a 30‑day satisfaction guarantee, offering an exchange or refund if the customer is not fully satisfied.
