COLLAPSIBLE COUNTER BLADE

The Pezzolato’s chipper can be supplied with a collapsible counter-blade (standard for PTH 820-1000,  on request for PTH 700-900)

The collapsible counter-blade is mounted on a running slide and secured with adjusted shear bolts. Whenever a hard body is accidentally entered into the chipper, the bolts are sheared and the counter-blade falls down, so that the foreign body exits before causing damages.
