1. A material processing apparatus comprising a power supply system, the power supply system comprising:
an internal combustion engine;
an electrical system comprising an electrical power supply configured to supply electrical power to at least one electrically powered component;
a hydraulic system comprising a hydraulic power supply configured to supply hydraulic power at least one hydraulically powered component;
at least one controller for controlling the operation of said power supply system, wherein said electrical power supply comprises at least one battery and an electrical generator, and wherein said internal combustion engine is mechanically coupled to said electrical generator in order to drive said electrical generator,
and wherein said at least one controller is configured to operate said power supply system in any one of at least two power supply modes in which said at least one battery and/or said electrical generator supply electrical power to said at least one electrically powered component,
and wherein said electrical generator is a motor-generator, and said hydraulic power supply comprises a mechanically powered pump, said motor-generator being mechanically coupled to said pump to enable transmission of mechanical power from said motor-generator to said pump,
and wherein said at least one controller is configured to operate said power supply system in at least one mode in which said motor-generator operates as a motor and in which mechanical power is transmitted from said motor-generator to said mechanically powered pump, and in which said motor-generator receives electrical power from said electrical system, and in which the internal combustion engine is switched off.
