A linkage adjustment system adapted to adjust a linkage, and a vehicle incorporating the same. In one embodiment, the linkage adjustment system adjusts a linkage operatively connecting an input (e.g., operator control lever of a lawn mower) to an output (e.g., drive system of a first drive wheel associated with a first (e.g., left) side of the mower). An adjustment device may adjust the linkage so that the first drive wheel rotates at the same speed as a second drive wheel (e.g., on the right side of the mower) when the control levers associated with both drive wheels are in a maximum forward position. A range setting arm of the system may adjust the total output of the first drive wheel (total forward and reverse output) to match the total output of the second drive wheel.
