Capacity and drivetrain
The engine is a 3.6-liter four-cylinder CAT delivering 75 horsepower and 318 Nm of torque at 1400 rpm. It is equipped with a particulate filter to reduce emissions and offers comparatively low fuel consumption per engine hour. The engine is approved for use with the renewable fuel HVO.
The hydraulic drivetrain with Terri’s AWS control provides smooth power transfer and strong traction in all conditions. With a tractive force of 88 kN and three gear ranges, Terri 3CW delivers excellent traction in off-road environments as well as efficient transport speed.
Stability and construction
The machine is eight-wheeled and built around an articulated center frame with a 45-degree steering angle. Each bogie is equipped with two hydraulic wheel motors, providing both strong pulling power and excellent mobility.
Terri’s low center of gravity contributes to high stability in uneven terrain or when working on slopes. The robust chassis and the eight driven wheels give the machine predictable behavior and a calmer driving experience for the operator.
Terri 3CW can easily be converted from harvester to forwarder in approximately 15 minutes by removing two counterweights from the rear section and swapping the harvester head for a grapple by releasing the quick couplings on the front of the crane. As a forwarder, the machine handles up to 6 tonnes of timber, and as a harvester it offers a cutting capacity of up to 41 centimeters tree diameter.
Mobility and terrain performance
With 70 cm of ground clearance and eight 500/50 x 17 wheels, Terri 3CW reaches areas where many other machines struggle. The combination of wide tires, balanced weight distribution and the hydraulic bogie design allows the machine to move gently even on soft ground.
The unique Terri AWS transmission system automatically distributes drive power to both the front and rear axles for optimal grip, and when needed, tracks and tire chains can be mounted for even greater traction and stability.
The active steering and proportional oil distribution provide smooth, precise movements even in narrow thinning corridors.
Operator environment and control
Terri’s spacious safety cab meets the latest standards and is mounted on vibration dampers to provide a comfortable operator environment. It is well insulated with low noise levels, and the elevated seating position ensures excellent visibility.
The seat is ergonomically designed, and the electrically braked, rotating seat base makes it easy to change driving direction. Joysticks and controls are integrated in the armrest for smooth operation of the machine, the timber grapple, the harvester head and the crane.
The Dasa computer with color display provides a clear overview of the machine’s systems and allows personalized settings for each operator.
Dimensions and application
The compact dimensions make the machine easy to maneuver even in dense thinning stands.
• Length: 6 643 mm
• Width: 2 050 mm
• Transport height: 3 100 mm
• Ground clearance: 700 mm
The agile design and solid construction make Terri 3CW a reliable tool for stand-based thinning and other assignments where low ground disturbance and high mobility are critical.
