Operating - Walker D21d Operator's Manual

Safety Instructions - Operating
Operate the mower only in daylight or in
1.
good artificial light with good visibility of the area
being mowed.
2. Sit on the seat when starting the engine and
operating the machine. Keep feet on the deck
footrests at all times when the tractor is moving
and/or mower blades are operating. Never op-
erate the tractor without a deck or imple-
ment installed.
3. For a beginning operator, learn to steer (ma-
neuver) the tractor with a slow engine speed
before attempting any mowing oper ation.
Be aware that, with the front mounted mower
configuration, the back of the tractor swings to
the outside during turns.
Do not mow around overhanging tree
branches or bushes at the same height as
the operator's torso and head where inad-
vertent contact may cause injury.
4. Remember, for an emergency stop, the forward
motion of the tractor can always be stopped by
pulling the Forward Speed Control (FSC) into
the NEUTRAL-PARK position.
5. In case either of the transmission drive belts
break during operation, and if the machine is on
a slope, the machine will freewheel down the
slope. To maintain control, immediately (1)
Release the steering levers and simultaneously
(2) Move the FSC to the NEUTRAL-PARK posi­
tion. When the machine is stopped or moving
slowly, engage the parking brake.
NOTE: The emergency stop procedure is ex­
actly the same procedure as used to normally
stop and park this machine.
6. Disengage the blade clutch, put the FSC in the
NEUTRAL-PARK position and engage the
Parking Brake before starting the engine (an
ignition interlock switch normally prevents
starting of the machine if these controls are in
the OPERATING position).
DANGER
Do not operate machine if the operator pres-
7.
ence safety switch system is not working.
Verify proper operation by having the operator
lift off the seat with the engine running and mov­
ing three controls, one at a time; (1) Move the
FSC lever out of the NEUTRAL-PARK position,
(2) Engage the PTO Clutch, and (3) Disengage
the Parking Brake.
controls should stop the engine after a 1/2 sec­
ond delay.
Do not run the engine in a confined area
8.
without adequate ventilation. Exhaust fumes
are hazardous and can be deadly.
9. Do not carry passengers - maximum seating
capacity is one (1) person.
10. Watch for holes, rocks, and roots in the terrain
and for other hidden hazards. When mowing
tall grass, mow higher than desired to expose
any hidden obstacles. Then, clean the area and
mow to the desired height.
11. Avoid sudden starts or stops. Before back­
ing the machine up, look to the rear to be sure
no one is behind the machine. Watch carefully
for traffic when crossing or working near road­
ways.
12. When moving forward, do not suddenly put the
tractor in reverse by rapidly pulling on the steer­
ing levers, especially when going downhill, as
this can lift the tractor tail wheel off the ground
and set up a bucking motion due to operator
overcontrol. If bucking does occur, immediately
stop the bucking action by pulling the Forward
Speed Control (FSC) lever into the NEUTRAL-
PARK position.
13. Disengage the blade drive when transporting
the machine across drives, sidewalks, etc. Nev-
er raise the mower deck while blades are
rotating.
DANGER
Do not mow or dump grass within 5 feet
(1.5 meters) of an embankment or retaining
wall with drop off.
Moving any of these
