1. A vertical pivoting gate operator for positioning a gate between an open position and a closed position, the gate operator comprising:
a motor drive assembly including a motor and a linkage assembly mechanically connecting a motor output to the gate such that in response to actuation of the motor, the linkage assembly transmits an opening force for positioning the gate toward the open position, and a closing force, for positioning the gate toward the closed position;
a counterbalance assembly including a biasing member operable to release stored energy against an input link to rotate a gate arm shaft so as to urge the gate toward the open position and to increase stored energy in response to rotation of the gate traveling toward the closed position to act against the gate as the gate approaches the closed position; and
a link shaft, the input link and a drive link pivotably mounted on the link shaft such that the link shaft is movable along at least one guide rod in response to the biasing member exerting a force on the input link.
