Abstract: Disclosed devices, systems, and methods allow an operator to maintain the speed of a vehicle's propulsion devices at selected speeds, and allow the operator to make adjustments to the selected speeds during or prior to operation of the vehicle. Disclosed embodiments can comprise adjustable limiters that are coupled to the control portion of the vehicle adjacent to or on the speed control levers. This allows the operator to hold the levers against a new limiting surface to keep the vehicle moving at a speed that is less than full speed with minimal aberration and less effort needed by the operator. The device can be adjustable to a range of positions corresponding to different speeds. The devices can also be selectively pivoted or moved out of the way of the speed control levers at any time to allow the levers to have their full range of motion.

Abstract: Disclosed herein are devices, systems, and methods that allow an operator to maintain the speed of a vehicle's propulsion devices at selected speeds that are less than full speed, and allow the operator to make adjustments to the selected speeds during or prior to operation of the vehicle. Disclosed embodiments can comprise adjustable limiters that are coupled to the control portion of the vehicle adjacent to or on the speed control levers. These devices can be set to a selected position to provide a stop that limits the levers to a modified maximum position that is different from the normal maximum, full-speed position. This allows the operator to hold the levers against a new limiting surface to keep the vehicle moving at a speed that is less than full speed with minimal aberration and less effort needed by the operator.
