Operating Instructions403. After the engine starts, make sure the oil pres-sure light goes off. If not, stop the engine imme-diately and find the cause of the problem. Makesure the oil pressure light is off prior to engagingthe mower blades and beginning operation.4. For Model MT and MTL, gradually move thechoke to the OFF position, keeping enoughchoke on to allow the engine to run smoothlyas it warms up. As soon as possible, move thechoke to the OFF position.IMPORTANT: For Model MT and MTL, make surethe choke is in the OFF position during normal en-gine operation; running with the choke in the ON po-sition CAN damage the engine.ADJUSTING GROUND SPEED AND STEERINGIMPORTANT: If the DSD52 or DSD62 Mower deckis installed on the tractor, make sure the dolly wheelis 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: If the FSC lever will not stay in theselected position, the friction lock needs to beadjusted. Contact your Walker Dealer.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. Never operate thetractor without a deck or implement in-stalled.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.
