Terri 3HW

The ultimate harvester for in-stand thinning with absolutely first-class navigability. With a 70-centimetre ground clearance, hardly anything can stop this harvester.

Flexibility is fundamental when it comes to stand-operative thinning. Terri 3HW is the ultimate forestry machine that performs best even in the most challenging conditions. An elite level of cabin comfort, high ground clearance and world class traction and bearing capacity are just some of the benefits of this fearless and powerful workhorse.

The ground clearance is an incredible 70 centimetres, providing fantastic surface negotiability even over rocky or hilly terrain. Thanks to the eight wheels, all of which are drive wheels, a high degree of ground contact is also ensured, which optimises traction and driver comfort. Because the cabin rests on pairs of double wheels, this also means a less bumpy and rough driving experience.

Add to this a spacious cabin equipped with the very latest technology. A strong Cat engine of 3.6 litres and the option to choose between the cranes Mowi P40 or Mowi P40T with a strong unit from Log Max.

At Terri we want your work shift to be comfortable. Which will be the case with this powerful harvester.

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.


We develop our machines based on three basic requirements: gentleness to nature, comfortable workplaces for the driver and, of course, the right properties for efficient and smart forestry work. As a manufacturer of modern forestry machines, the fact is we play a decisive role that includes great responsibility for the future and sustainable forestry.


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.
