Improved shredding machine shredding mechanism having elongated wall and gate structure defining a chamber. The chamber walls have margins defining a material entryway at one common end and margins defining a material discharge aperture at the remote end of the chamber from the entryway. An electrically driven rotatable shredder journaled in the wall structure intermediate the entryway and discharge aperture. The gate pivotally mounted externally of the chamber for movement within the chamber at the entryway and extending from a point adjacent to one of the walls divergingly relative to the wall and terminating remote from the pivotal mounting and from the wall defining a progressively constricting chamber as to area of the chamber in latitudinal cross-sectional dimension from entryway to discharge aperture in a selected position of the gate. Electronic sensing means for the motor for rotating the shredder to sense resistance increases to the rotation of the shredder and coupled with hydraulic rams interconnecting the gate and the machine for pivoting the gate from the selected position to a plurality of additional positions progressively increasing the cross-sectional dimension of the chamber thereby increasing the volume thereof. In the selected position the gate assists in guiding material through the chamber. The gate has a plurality of combs for cleaning out between the shredding teeth when the gate is in the selected position.
