Raise the body.2. Lift the transmission lockout lever on both theRH and LH transmissions and secure into placewith the locking cam.3. The mower will “freewheel” with the levers in theLOCKOUT position. The levers must be in thehighest position to completely unlock thetransmissions.Lockout Lever - Freewheel Position4. After moving the mower, release the lockingcam, placing the lever DOWN in the normalOPERATING position. Make sure the trans-mission lockout plunger on the side of the trans-mission case (activated by the lockout lever) iscompletely released, otherwise the transmis-sion operation will be erratic.Lockout Lever - Normal Operating PositionRECOMMENDATIONS FOR MOWINGIMPORTANT: Operate the engine at full speedwhen mowing, to allow the engine to produce fullhorsepower and to increase efficiency of the enginecooling system.• Keep the mower deck and discharge chute clean.• Mow with sharp blades. A dull blade tears thegrass (resulting in poor lawn appearance) and usesextra power (slowing the mowing speed).• It is preferable to cut grass when it is dry and nottoo tall. Mow frequently and do not cut grass tooshort. (For best appearance, cut off 1/3 or less ofexisting grass height.)• When mowing, operate the engine at or near fullthrottle for the best cutting action and performanceof the grass handling system (GHS). Mowing with alower engine RPM causes the mowing blade to notcut clean and tear the grass. The engine isdesigned to be operated at full speed.• When mowing in adverse conditions (tall and/orwet grass), mow the grass twice. Raise the mower tothe highest setting - 4 in. (102 mm) - for the first passand then make a second pass cutting to the desiredheight.• Use a slow setting on the FSC for trimmingoperations.Cam inLOCKOUTPositionPlungerDepressedLockout LeverCam inUNLOCKEDPositionLockout LeverPlungerReleased
