1. A vehicle, comprising:

  • a first prime mover;

    a second prime mover;

    a transmission coupled to absorb power from the first prime mover or the second prime mover;

    a power take-off operation selectively operable from the transmission;

    a control system operatively connected with the first prime mover, the second prime mover and the transmission for selecting an operating speed for the power take-off operation;

    the control system providing first and second available angular acceleration rates for the first and second prime movers as a function of angular velocity of the first and second prime movers for increases in operating speed of the power take-off operation; and

    the control system responding to a selection of increased operating speed for the power take-off operation by directing angular acceleration of an operable one of the first and second prime movers at no more than the lesser of the first and second available angular acceleration rates.
