Operating Instructions33ADJUSTING GROUND SPEED AND STEERINGIMPORTANT: If the DSD52 or DSD62 Mowerdeck is installed on the tractor, make sure thedolly wheel is retracted BEFORE moving.1. Move the FSC out of NEUTRAL-PARKposition to the desired forward speed. DONOT hold forward on steering levers. It is notnecessary to hold the FSC lever in positionsince a friction lock maintains the selectedlever position (and forward travel speed).NOTE: This is exactly the same procedureused to normally stop and park the machine.NOTE: If the FSC lever will not stay in theselected position, the friction lock needs to beadjusted. Refer to ADJUSTMENTS of ForwardSpeed Control Friction Lock in MaintenanceInstructions.2. Steer by pulling the lever on the side of desireddirection of turn, e.g., pull the LH lever to turnleft. To minimize the possibility of overcontrol,use only one hand on both steering levers.CAUTIONLearn to START, STOP, and MANEUVERthe mower in a large, open area.If the operator has not operated a ma-chine with LEVER STEERING OR DUALHYDROSTATIC TRANSMISSIONS, steer-ing and ground operation should belearned and practiced until the operator iscompletely comfortable handling the ma-chine BEFORE ATTEMPTING TO MOW.DANGERKeep feet on footrests at all times whenthe machine is moving.WARNINGIn case either of the transmission drivebelts break during operation, and if themachine is on a slope, the machine willfreewheel down the slope. To maintaincontrol, immediately (1) Release thesteering levers and simultaneously (2)Move the FSC to the NEUTRAL-PARKposition. When the machine is stoppedor moving slowly, engage the parkingbrake.Beginning Recommendations are:♦ Learn operation of the mower in an openarea away from buildings, fences, and ob-structions. Learn operation on flat groundBEFORE operating on slopes.♦ Start maneuvering the mower with SLOWengine speed and SLOW Forward SpeedControl setting until familiar with all operat-ing characteristics.♦ Remember it is not necessary to hold thesteering levers forward (a unique Walkerfeature); always PULL on the levers forsteering or for reverse motion of the mower.♦ Learn to operate the mower with your lefthand on the steering levers and right handon Forward Speed Control. The use of twohands on the steering levers tends to causeovercontrol.♦ Learn to operate the steering levers withsmooth action. Jerky movements are hardon the transmission and lawn. For sharpturns, do not allow the inside wheel to stopand twist on the grass. Pull the steering le-ver controlling the inside wheel into reversefor a smooth “rolling” turn (one wheel roll-ing forward while the other rolls backward).♦ Practice maneuvering the mower untilyou can make it go exactly where you areaiming.♦ Remember, for an emergency stop, or incase of loss of control, machine movementcan always be stopped quickly by pullingthe Forward Speed Control into the NEU-TRAL-PARK position.
