Terri 3FW

Terri 3FW is a compact and powerful forwarder designed for thinning operations where strength, precision and care must work together. The machine combines high capacity with low ground impact and is built to perform reliably, day after day, in varying terrain.

Capacity and drivetrain
The engine is a 3.6-liter four-cylinder CAT producing 75 horsepower and 318 Nm of torque at 1400 rpm. It is equipped with a particulate filter to reduce exhaust emissions and has 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 3FW offers excellent pulling power in the 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 operating on slopes. The robust chassis and the eight driven wheels give the machine predictable behavior and a calmer driving experience for the operator.

The rear section features a front gate covering 2.45 m² and a payload capacity of 6 tonnes. The wagon is available in two different lengths depending on the assortment being handled. Both wagon versions also feature an extendable rear bunk, allowing the load area to be increased by an additional 600 mm.

Mobility and terrain performance
With 700 mm of ground clearance and eight 500/50 x 17 wheels, Terri 3FW goes where many others struggle. The combination of wide tires, balanced weight distribution and a 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 deliver smooth, precise movement 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 operator position provides 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 intuitive operation of the machine, the grapple 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 applications
The compact dimensions make the machine easy to maneuver even in dense thinning stands.

  • Length: 6 643 / 7 243 mm
  • Width: 2 050 mm
  • Transport height: 3 100 mm
  • Ground clearance: 700 mm

The agile design and solid construction make Terri 3FW a reliable tool for stand-based thinning and other jobs where low ground disturbance and mobility are critical.

Frequently Asked Questions about Terri

  • You have the possibility to choose between tracks and skid protection. Here, in our product catalog, you can find all options.

  • The Terri AWS is a fully automatic solution that ensures optimal traction regardless of the terrain. It replaces the classic locking differential, and it presents a noticeable advantage on terrains that are steep or have poor bearing capacity. The system is sharper than the previous technology and it enables you to get more power out of each wheel. As a driver, you never need to decide if or when to switch on the AWS; everything happens automatically.

  • Terri´s machines thrive with first and second thinning and when driving on sensitive ground. Thanks to its first-rate range, it does a perfect job even when the terrain is uncompromising.

  • Compared to its predecessor, Terri 3 is upgraded with 20 innovations. These are for example updates in the cabin, in the design and under the bonnet. Fully automatic optimal traction (Terri Automatic Wheel System, AWS), stronger and more fuel-efficient engine and a 24-volt electrical system.

ADJUST WEIGHT AND BALANCE

On our forwarders you can quickly and easily move the rear bogie forwards and backwards. This smart idea means that the wagon’s balance can be adapted to the length of the wood. The rear platform can also be adjusted by 70 centimetres forwards or backwards. This means that the wagon part can easily be optimised for all different driving conditions.

FANTASTIC GROUND CLEARANCE

Our wheeled machines have an unbelievable ground clearance of 70 centimetres. That is the same as larger forestry machine models. Thanks to this, everyday work is made considerably easier, and you can navigate tougher and trickier terrain without a second thought or it affecting the work in the slightest. We are talking about the absolute best navigability.

Terri AWS

Thanks to Terri AWS (Automatic Wheel System), traction, power and manoeuvrability are automatically guaranteed. The system quite simply generates more power and the right amount to each wheel and all you as a driver have to do is focus on driving. Terri AWS is our own invention, which we are very proud of and pat ourselves on the back for.
