Why Choose the Red Roo HT912 Hydraulic Trencher?

1. Fully Hydraulic Drive – Built for Commercial Reliability

One of the most important advantages of the Red Roo HT912 is its fully hydraulic operating system.

Unlike conventional mechanical-drive trenchers that rely on belts, chains and sprockets for their main drive systems, the HT912 uses hydraulic power to operate its travel and trenching functions.

Key benefits include:

• Smooth and controlled self-propelled operation.

• Forward, neutral and reverse travel.

• Reduced reliance on conventional mechanical drive components.

• Convenient control of trenching operations.

• Design suited to repeated commercial and hire industry use.

• Reduced routine drive-system maintenance requirements.

For hire companies and professional contractors, hydraulic drive can help reduce downtime and improve operating convenience.

2. Self-Propelled Operation – Less Manual Effort

The HT912 features hydraulically powered wheels, allowing operators to move the machine forwards or backwards without manually pushing the full weight of the trencher.

This is an important advantage over non-self-propelled trenching machines, particularly during longer trenching operations or when manoeuvring a machine weighing approximately 280kg.

The self-propelled design assists operators with positioning, trench alignment and moving between work areas.

3. Powerful 9HP Honda GX270 Engine

The HT912 is powered by a genuine Honda GX270 OHV petrol engine, rated at 9HP.

Honda engines are widely used in commercial equipment because of their established reliability, serviceability and availability of replacement components.

The engine provides the power required to operate the HT912's hydraulic drive and digging functions in a range of suitable soil conditions.

4. Trenching Depth Options Up to 600mm

The Red Roo HT912 is available with three digging boom configurations:

• 300mm (12 inches).

• 450mm (18 inches).

• 600mm (24 inches).

With a nominal trench width of approximately 100mm, the HT912 is ideal for preparing narrow trenches for irrigation pipes, sprinkler systems, suitable electrical conduits and communications cabling.

Its narrow cutting profile helps minimise unnecessary excavation, reducing the quantity of soil requiring reinstatement.

Actual digging depth and performance depend on the selected boom, chain configuration and ground conditions.

5. Reversible Digging Chain

The HT912 features a reversible digging chain, allowing operators to reverse the chain when necessary to assist in dislodging rocks or trapped debris.

This can be particularly valuable when trenching in difficult ground conditions where material may become lodged in the digging assembly.

The reversible chain improves operational convenience and assists with clearing suitable obstructions in accordance with the manufacturer's operating procedures.

6. Commercial Safety and Operator Control

The HT912 incorporates an operator-presence safety clutch designed to stop wheel and digging chain operation when released.

Additional practical features include:

• Convenient operating controls.

• Heavy-duty digging boom and crumber bar.

• Dirt-clearing auger.

• Protected boom pivot arrangement.

• Freewheeling wheel hubs for manual repositioning.

• Integrated lifting hook for appropriate mechanical handling.

• Commercial-duty powder-coated finish.

These features help make the HT912 a practical choice for trained operators and commercial hire businesses.
