Beeping when ready to roll.
All loaded and ready to go last fall, we had turned on the engine, unloaded the levelers, released the brake after making our final outside round to ensure everything was up and nothing was left behind. WE kept hearing this beeping sound. We check the air pressure, we reset the brake, we pumped the break petal. and we still had the beeping. Long story, short answer. Check your Drivers Chair to ensure it has locked in completely. Ours seemed locked, but when we released it and turned it back into place for driving, the beeping stopped.
