The Hopper Walker Swing-Hopper Remote-Control System is a portable, remote-control-activated, 12-volt DC, high-torque motor kit that mounts to any swing-away hopper, allowing the farmer to position it under his grain trailer without having to get out of the vehicle to do so manually. The remote has six function buttons that control the hopper's movement: three for automatic in and out and for stopping at predetermined, adjustable limits; and three for momentary in and out and for inching the hopper along to precisely positioning it under the trailer. Should the remote fail, there's a hard-wired control box with emergency stop and momentary in and out. Installation involves simply bolting the motor kit onto the auger and plugging it in. Three models available.
