HJ -4

It is a non-direct feeding chipper, in which the material is fed diagonally into the chippers. The blades draw the wood in themselves, and that makes the work lighter.

The Junkkari HJ 4 chipper is especially suited for environmental and landscape chipping.



The HJ4 is equipped with a hydraulic feeding device. It has one feed roller, and it gets its power from the tractor’s hydraulics. The HJ-4 requires one pressure valve from the tractor and one return to the feeding device hydraulics. The output needed by the hydraulics system is 20 l/min and pressure a minimum of 140 bars.

The chipper’s disc works like a flywheel and ensures even woodchips regardless of changes in the load. The disk’s blades can be adjusted by the required woodchip size. The chipping disk has blow wings, which efficiently spread the woodchips straight into the environment.
