Abstract of the Disclosure A push arm assembly for eccentrically operating a ratchet gear by means of a driving pawl to rotate an unloader arm in the bottom of a silo or the like. Directional change of the driving pawl is accomplished by withdrawing the driving pawl into its housing and rotating it 180° and then releasing it to place the pawl in engagement with the ratchet to drive the latter in the predetermined forward or reverse rotation. The driving pawl also can then be rotated 90° into a position out of engagement with the ratchet when rotation of the unloader arm is not desired. A holding pawl is also employed in con- junction with the driving pawl to restrain the ratchet during the period of oscillation when the driving pawl disengages the ratchet and recedes to engage the next tooth on the ratchet. Directional change of the holding pawl and disengagement from the ratchet is accomplished in the same manner as the driving pawl.
