This invention is new to the art of driving hydraulic pumps because up to now hydraulic pumps have been driven by electric motors or separate engines of some kind. Now with this invention extra motors and engines are unnecessary. Implementation of this invention requires that the crusher be driven by a driveshaft. Then the main sheave is free to drive an auxiliary jack shaft that drives a transfer case. This transfer case in turn is used to drive multiple hydraulic pumps.
