Nisula 425H is a thinning grapple with additional blades. The wood passes through the grapple with controlled speed. The new type of grapple control makes wood handling fast and accurate.
The new, larger traction motors provide 20% more feed power than before. New machined front blades provide improved pruning performance and wear resistance. The additional blades make the new 425H harvesting head productive even with larger trees, which other thinning harvesters in the same weight class cannot normally do. Additional inserts also achieve a larger pruning diameter. The grapple is the best choice for thinning.
