The ARM mode automatically raises the plow when the operator shifts the vehicle to reverse. The ALM mode automatically lowers the plow when the operator shifts the vehicle in reverse. It features one-button functionality, illuminated buttons and self-diagnostics. This pistol grip controller retrofits back to replace Meyer Touch Pad Controller ( 22154).
