    Elizabeth Greene's Tools
    If you're looking for an off-the-shelf way to do this, Deweze makes and sells underhood hydraulic kits for tow trucks. These clutches aren't "cheap", but the pricing isn't terrible. e.g. My old red truck would take a 742009 clutch which is around $300.

    The last tow truck I rode in had a toggle switch that held the engine up at around 2,000 RPMs when the hydraulics were engaged. Does anyone know how they do that?
