Adjusting the Seat Ride Suspension

The number of seat springs can be changed to maximize rider comfort. More springs should be used with heavier operators and on rough terrain. Fewer springs should be used with lighter operators and when mowing smooth, well established lawns. Always keep the number of springs on the left and right side the same when adding and removing springs.
