The 4 Way/3 Way DC Power Unit – Electric Controls from Buyers Products is an all-in-one, compact power pack. This horizontal-mount power unit is ideal for powering snow plow lift and angle operations. It includes pre-wired rocker switch controls that provide 4-way/3-position fingertip control for Power Up/Hold/Gravity Down (plow hoist), and 4-way for exact left-right angling of the blade. A crossover relief valve protects the angle cylinder and the plow blade should the plow strike a hidden object.
