CONTROLS
Lift and traction levers
(operator's right side)
LIFT LEVER (F) - Used to raise the cutterdeck to
maximum height for transport, curb climbing or blade
changing. To return to preset height of cut, lower lift
lever until it contacts height of cut pin A.
TRACTION LEVERS (L)-
Each of the two
traction levers controls the drive wheel located on
the same side. They control the forward and reverse
movement of the machine, provide steering and also
provide dynamic braking.
The operator must be in the seat and the parking
brake must be OFF to engage the traction drive.
To engage traction drive, move the traction levers
toward the center of the machine until they are out of
neutral lock slot S.
Forward movement - To move the machine straight
ahead, push both traction levers forward equally from
their neutral position. Forward speed increases as
the levers are moved farther forward from the neutral
position. Maximum forward speed is reached when
the levers hit the front of the forward-reverse slot.
When traveling forward, pulling the traction levers
rearward slows the machine. The machine stops
when the neutral position is reached.
Reverse movement - To move the machine straight
back, pull both traction levers back equally from their
neutral position. Reverse speed increases as the
levers are moved back farther. Maximum reverse
speed is reached when the levers hit the rear of the
forward-reverse slot. When moving in reverse, push-
ing the levers forward slows the machine, and the
machine stops when the neutral position is reached.
NOTE: Reverse is spring loaded to return to neutral.
This spring resistance may be felt when moving the
traction levers into reverse. When the levers are
released in reverse, spring tension will slowly return
them to the neutral position.
STEERING
- To steer, move one lever forward and
one back.
Turns during forward movement:
Right turn - move the right traction lever back
toward neutral to slow the right drive wheel,
Left turn - move the left traction lever back to-
ward neutral to slow the left drive wheel.
Turns during reverse movement:
Reverse right turn - move the right traction lever
forward toward neutral to slow the right drive
wheel.
Reverse left turn - move the left traction lever
forward toward neutral to slow the left drive
wheel.
Slow, sweeping turns are made with both traction
levers on the same side of neutral and slightly
apart. True zero radius turns about the center of the
machine are made by having one lever in reverse
while the other is in forward. By varying the relative
positions of the two levers, the rate of turn is varied to
suit the mowing situation.
Slow down before making sharp turns. The machine
is capable of turning very rapidly when the levers are
moved further apart from each other. Loss of control
and/or turf damage may result.
