Abstract
The present disclosure relates to a material reducing apparatus adapted to be coupled to a vehicle by a pivot arm or other structure. The material reducing apparatus includes a reducing head with rotary reducing component. The reducing head can be titled about a tilt axis relative to the vehicle and can be raised and lowered relative to a vehicle. The reducing head has a thrown object deflector that automatically moves relative to the rotary reducing component when the reducing head is tilted relative to the vehicle.
Claims20
A material reducing apparatus comprising:
- a reducing head including a rotatable reducing component that carries a plurality of cutters, the reducing head also including a thrown object deflector and a cover portion, the cover portion extending along a length of the rotatable reducing component and covering a portion of a circumference of the rotatable reducing component, and the thrown object deflector extending along the length of the rotatable reducing component and being movable relative to the cover portion and also movable relative to the rotatable reducing component;
- an arm for coupling the reducing head to a vehicle, the arm being coupled to the reducing head at a first pivot axis for allowing the reducing head to be pivoted relative to the arm between a forward tilt orientation and a backward tilt orientation, the arm also being pivotally movable about a second pivot axis for allowing the reducing head to be moved relative to the vehicle between a raised position and a lowered position;
- and
- a position control arrangement that interfaces with the thrown object deflector and automatically moves the thrown object deflector relative to the cover portion at least when the reducing head is pivoted about the first axis to automatically control a thrown object trajectory angle of the reducing head.

- a pivot arrangement that includes a first pivot location that allows the reducing head to be pivoted between a forward tilt orientation and a backward tilt orientation, and also includes a second pivot location for allowing the reducing head to be moved between a raised position and a lowered position;
- and
- a mechanical linkage that couples to the thrown object deflector and automatically moves the thrown object deflector relative to the cover portion at least when the reducing head is moved between the raised and lowered positions to automatically control a thrown object trajectory angle of the reducing head.
