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 exhaust 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 3HW delivers excellent pulling power in forest terrain 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 traction 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 operating experience for the driver.
The harvesting module on Terri 3HW is equipped with crane tilt and a 7.5 m parallel crane. The harvester head can be fitted with stump treatment and color marking, and efficiently fells trees up to just over 40 cm in diameter.
Mobility and terrain performance
With 700 mm of ground clearance and eight 500/50 x 17 wheels, Terri 3HW goes where many others struggle. The combination of wide tires, balanced weight distribution and 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. When required, tracks or tire chains can be mounted for even greater traction and stability.
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 working environment. It is well-insulated with low noise levels, and the elevated position ensures excellent visibility.
The operator’s seat is ergonomically designed, and the electrically braked, rotating seat base makes it easy to change driving direction. Joysticks and controls are integrated into the armrest for intuitive control of the machine, the harvester head and the crane.
The Dasa computer with color display provides a clear overview of the machine’s systems and enables personalized settings for each operator.
Dimensions and applications
The compact dimensions make the machine easy to maneuver even in dense thinning stands.
• Length: 5 928 mm
• Width: 2 050 mm
• Transport height: 3 100 mm
• Ground clearance: 700 mm
The agile design and solid construction make Terri 3HW a reliable tool for stand-based thinning and other operations where low ground disturbance and mobility are critical.
