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

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

The HJ 4 chipper is available as M and G models.

The HJ 4 M is equipped with a manual infeed chute. It lends itself to chipping branchless trees or trees with a few branches.

The HJ 4 G is equipped with a hydraulic feeding device. It has one feed roller, and it gets its power from the tractor's hydraulics. The G model 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 bar.

The chipper's disc works as a flywheel and ensures even woodchips regardless of changes in the load.

The disc's blades can be adjusted by the required woodchip size. The chipping disc has blow wings, which efficiently spread the woodchips straight into the environment.
