The new Junkkari HJ-250 chipper is ideal for chipping larger logs as it can be used for chipping wood up to 10inch (25cm) in diameter, it can be used to chip material to be used in parks or as biofuel and energy source.
HJ-250 is a non-direct feeding chipper. As the blades draw the wood in themselves, it requires less power. It comes in three versions: the M, G and GT models.
The HJ-250 G model is a chipper with a hydraulic feeding device. Its two feed rollers are powered by the tractor’s hydraulics.
The HJ-250 GT model is almost identical to the G model: the only difference is that its feeding device has an independent hydraulic tank and pump. Therefore no additional hydraulics is needed.
Third available version HJ-250 M is mechanical chipper without separate feeding device. For safety reasons, all M-model chippers are equipped with a patented feed stopper operated with the control handle.
The new discharge chute gives excellent airflow and easy adjustability.
The HJ-250 chipper can be fitted with an optional loader feeding equipment that contains the following elements: a stronger infeed chute, a No-Stress rotation guard, an electronic feed and discharge chute control.
