Understanding Counterbalance Performing a Fan-Reverse Operation The counterbalance system maintains hydraulic back pressure on the deck-lift cylinders. This pressure improves traction by transferring the mower-deck weight to the mower-drive wheels. The counterbalance pressure has been set at the factory to an optimal balance of after-cut appearance and traction capability in most turf conditions. The machine-fan speed is controlled by the hydraulic-fluid temperature and engine-coolant temperature.
Important: Do not run the starter motor increments. By holding the switch down, the engine automatically moves to HIGH or LOW IDLE, depending on which part of the switch you pressed. more than 30 seconds at a time or premature starter failure may result. If the engine fails to start after 30 seconds, turn the key to the OFF position, check the controls and procedures, wait 30 additional seconds, and repeat the starting procedure. 5.
