A powering system for a paper shredder carried by a vehicle having a two speed rear differential provides a power takeoff driven by a drive pulley irrotatably carried on a medial drive line shaft inserted between the vehicle forward and rearward drive line shafts. The range selector of the differential is modified to have a null position between speed ranges whereat rotational motion of drive line is not communicated through the rear differential to vehicle axles and wheels. An air bag carried powered by the vehicle pneumatic system selectively tensions and slackens drive belt tension to engage and disengage the power takeoff. Auxiliary apparatus to load unshredded paper into a storage area, feed the unshredded paper to the shredder and unload shredded paper from the vehicle are electrically powered by vehicle rechargeable batteries through switching means to regulate motor starting, stopping and reversing and to regulate shredder speed.
