Abstract
A spreader assembly may include a hopper, a pair of augers positioned in a dual auger arrangement and a metering gate assembly including a gate and a biasing force generator. The gate may have a general M-shape with an inner extension and may be positioned generally above the augers with the inner extension extending between the augers. The biasing force generator may be operable to apply a biasing force to the gate causing the gate to operate as a metering gate.
