Neutral Lock
To start, lock unit in neutral by pushing
both Travel-Steering Control Levers
outward – to each side – from centered
(neutral) position.
Neutral Lock Position
Straight Forward
Push the Travel-Steering Control Levers
SLOWLY forward the same distance from
the centered (neutral) position. The further
you move the levers, the faster the unit will
travel forward. (Travel-Steering Control
Levers have quick response timing.)
Straight Backward
Pull the Travel-Steering Control Levers
back the same distance from the centered
(neutral) position. The further you move
the levers, the faster the unit will travel in
reverse.
Turns
Move one Travel-Steering Control Lever forward and
the other backward. Pushing the lever forward from the
centered position moves the unit forward on that side;
pulling the lever back from the centered position moves
the unit backward on that side.
1. Left Lever further forward than Right
Lever: Turns the unit to the Right.
2. Right Lever further forward than Left
Lever: Turns the unit to the Left.
NOTE: Aggressive turning can scuff or damage lawns.
ALWAYS keep both wheels rotating when making
sharp turns. DO NOT make turns with inside wheel
completely stopped. To obtain minimum turning radius,
slowly reverse inside wheel while moving outside wheel
OE0060
slowly forward.
Attachment Lift Lever
The position of the lift lever determines the cutting
height.
To adjust the attachment height:
1. Squeeze locking lever into handle.
2. Raise or lower attachment handle to
desired height.
3. Release locking lever to set position.
Maximum cutting height is 4-3/8 inches; lowest cutting
height is 1-3/8 inches. Intermediate positions allow
cutting heights between these values.
The heights are measured from the ground to the blade
tip with the engine NOT running. These heights may
-A-
vary depending upon the soil conditions, height of
grass and types of grass being mowed.
OE0161
NOTE: On the 42" Deck, the Anti-scalp roller height
must be adjusted to correspond with the attachment
height or so the anti-scalp rollers are not lower than the
desired cutting height. See Adjustments.
• For best cutting performance, grass over 6 inches
in height should be mowed twice. Make the first
OE0200
cut relatively high (4 inches); the second to
desired height.
WARNING: AVOID injury from stored energy
in lift assist spring. DO NOT unlock
attachment lift lever with mower deck
removed. ALWAYS engage Attachment Lift
Lever Lock when removing mower deck.
