About the machine:

The Heizohack HM4/6-300 series of wood chippers are ideal for owners of wood chip boiler systems to produce quality wood fuel chip for there own use.

The Heizohack ‘Stress control’ system

Both the HM4-300 & HM6-300 have a maximum chipping diameter of 30 cm (12″) and as all Heizohack chippers are supplied with the Heizohack ‘Stress control’ system which ensures a quality chip by controlling the in-feed speed of the chipper according to the power of the tractor driving the chipper.

The large in-feed height of 30 cm allows you to process bushes, branches, fence poles, saw mill waste etc., even entire tree trunks into high grade wood chips

Manually Fed

The manually fed HEIZOHACK – wood chippers can break down all wood waste, such as slats, beams, logs, blocks or branches and trunks with a diameter up to a maximum of 300mm or 400mm. A steel conveyor belt and a pressure roller with welded tongs ensure a powerful and reliable feeding of the material.

The HEIZOHACK – wood chippers are equipped with a low drag drum chip rotor. Thereby flawless operation is also possible with low drive performance and the fuel consumption is reduced. The drive can take place using a propeller shaft, via an internal combustion engine (HM 6-300 VM) or via an electro-motor (HM 4/6-300 EM, HM 5/6/8-400 EM).

The hydraulic feed units’ supply is undertaken via it´s the own on-board hydraulic system.

An external oil supply is not necessary. The size of the wood chips can be influenced by the individually adjustable feed speed and the easily exchanged sieve. The ejection of long pieces is prevented by the sieve.

• The counter-knife can be used quadrilaterally.
• The quick exchangeable blades can be re-sharpened when fitted.
• The feed table and the ejector spout are foldable and supported by pneumatic shock dampers.

Upon request, the ejector spout rotation and the ejector flap adjustment are possible by remote control.

The feed speed is adjustable via a flow divider and the direction of the feed elements reversible by the feed safety lever.
