must be relieved. Parkmachine on a levelsurface, make
sure that PTO switch is OFF, lower cutting deck fully,
stop engine and engage parking brake. Wait for all mov-
ing parts to come to a complete stop.
System pressure inlift circuit is relieved when thecutting
deck is fully lowered.
System pressure in mow circuit is relieved when the
PTO switch is disengaged.
To relieve hydraulic pressure in traction circuit, turn igni-
tion switch to ON (engine not running) andmove traction
pedal to both forward and reverse directions. Turn igni-
tion switch to OFF after relieving traction circuit pres-
