Nisula unveils new N6 harvester

The N6, the latest in the Finnish firm’s N Series, might look like the previous N5 but that’s where the similarities end. Redesigned from the ground up to better meet the needs of foresters, it features a fresh cabin look, new frame, higher ground clearance and more engine power.

That’s all thanks to two and a half years of input from users of previous models, who worked closely with Nisula to come up with the final blueprint. 

Improving the productivity of the operator, according to Nisula, the new cabin’s large windows give good visibility around the machine and up toward the treetops.

The transmission is a hydrostatic-mechanical power transmission with differential locks. With an optional roadworthiness add-on, the harvester can be moved between sites by driving.

A Stage V, Agco Power 49LFTN, with a power output od 140 kW or 190 hp, the engine also has torque of up to 800 Nm. The combination of good fuel economy and fuel tank size gives a runtime of about 35 hours.

The hydraulic pump is a Kawasaki 140cc axial piston pump that delivers a operating pressure of 230 bar. The oil tank holds 200 litres.
Nisula offers three different options of harvester heads from their own range: 555H, 500H, and 335E.

A Nisula spokesperson said: “After more than a decade on the market, the Nisula N-series thinning harvester has been fully redesigned to better meet the needs of thinning. 

“The guiding principle of the new design was to develop a thinning harvester that is as practical as possible and complementary to mainstream harvesters. The new N6 is highly suited for thinnings. 

“The ground pressure of the six-wheel half-track is sufficiently low to allow it to also be used in the summer. Based on feedback, many forest owners have found Nisula’s six-wheel thinning harvester ideal in peaty terrain conditions, even in the summer.”
