Abstract
Abstract A surburban tractor having a transmission control lever moveable between park and drive positions cooperatively related to a rear pivotable deck, a starter switch, and a parking lock. The control is so structured and orientated that when in the drive position the starter switch is open, the parking lock disengaged, and the rear deck is substantially prohibited from pivotable movement. In the park position the starter switch is closed, the parking lock engaged, and the rear deck is free to be pivoted.
