A rear edge of the base can be bolted to the transverse beam of the frame of the vehicle with the angle of the base being adjusted by the bolted connection. The base carries bearing blocks which support the power takeoff shaft and in one example an electric clutch.

  • Patent number: 4763744
    Abstract: A power takeoff attachment for a conventional road vehicle includes a plate member with a rod extending transversely thereto and of a length so that the outer end thereof can be inserted into a V-shaped space between the torsion bar bracket and the frame of the vehicle. A rear edge of the plate can be bolted to the transverse beam of the frame of the vehicle with the angle of the plate being adjusted by the bolted connection. The plate carries a pair of bearing blocks which support the power takeoff shaft. Drive is communicated to the shaft via chain or belt coupling from a sprocket mounted at the pulley of the vehicle engine and attached to the pulley by bolts which pass into the pulley and into the crank shaft. The power takeoff shaft is exposed at a front end of the vehicle and can be used to drive an implement for example a snowblower or pump mounted on sleeve-shaped brackets carried on an underside of the vehicle frame.
