1) does the GrandStand (48") have OPERATOR PRESENCE controls? Does that 'right-side' control handle pop up (if let go) to stop the machine? 2) does the optional OCDC-operator-controlled-discharge-chute add anything at all to the width of the deck, even as little as the thickness of sheet steel? or is it all contained within the width of the deck (48")? Thank you for your responses.
