The Junkkari HJ-261 is a direct-feed chipper with extremely high woodchip quality. It is especially suited for stoker boiler use because the chipper chops wood to the cross fibre. The feed opening is in a 90 degree angle to the blade disc.

The HJ-261 is a multi-speed chipper with two different speeds for the application needed. The faster rotation speed produces mostly woodchips for compost. The lower speed is used for chipping harder wood. Additionally, the blowing power grows with speed, which is useful when chipping e.g. sticks.

The HJ 261 chipper is available as G and GT models.

The G model has a feed system that is run by the tractor’s hydraulics. The output needed by the hydraulics is 5.5 gallon/minute (20 l/min) and pressure a minimum of 140 bar.

The GT is equipped with a feeding device with its own PTO-driven hydraulics tank and pump.

The hydraulic feeding device holds tightly to the material to be chipped. The feed roller moves the wood towards the blade disc, which cuts the wood one chip off at a time. The resulting woodchips are pushed via the blade openings to the blow wings and out through the discharge chute.

The feed speed can be changed by adjusting the hydraulic motor’s revolutions. The grip of the cogged feed roller is tight and the motion steady. The feed rollers can be stopped when necessary, and the material can be reversed out.

The No-Stress rotation guard, which is available as an accessory, stops the feed when the tractor output rotations get too low.

The HJ-261 chipper can be accessorised with loader feeding equipment which include:
– infeed chute that withstands load feeding
– No-Stress rotation guard
– electric controller for tractor cabin with electronic turning of discharge chute and visor, feed roller control and No-stress setting

The chipper installs onto the tractor’s 3-point linkage. The installing and detaching is quick and easy.
