Adjusting the Counterbalance WARNING The counterbalance system maintains hydraulic back pressure on the deck lift cylinders. This counterbalance pressure transfers cutting deck weight to the mower's drive wheels to improve traction. The counterbalance pressure has been factory set to an optimal balance of after-cut appearance and traction capability in most turf conditions. Decreasing the counterbalance setting can produce a more stable cutting deck, but can decrease the traction capability.
