System Characteristics - Craftsman 917.20403 Operator's Manual

TO CONTINUE MOWING
* Return to seat.
, Place attachment clutch switch first in
"DISENGAGED" position and then in
"ENGAGED" position.
NOTE: Any attempt to place attachment
clutch switch in the "ENGAGED" position
without the operator first being in the seat
will immediately shut off engine.
TO USE THROTTLE CONTROL (D)
Always operate engine at full speed (fast).
• Operating engine at less than full speed
(fast) reduces engine's operating efficiency.
• Full speed (fast) offers the best mower
performance.
TO MOVE FORWARD AND BACKWARD
The direction and speed of movement is
controlled by the forward and reverse drive
pedals.
1. Start tractor and release parking brake.
2. Slowly depress forward(K) or reverse(L)
drive pedal to begin movement. Ground
speed increases the further down the
pedal is depressed.
TO USE CRUISE CONTROL (J)
The cruise control feature can be used for
forward travel only.
SYSTEM CHARACTERISTICS
The cruise control should only be used
while mowing or transporting on relatively
smooth, straight surfaces. Other conditions
such as trimming at slow speeds may cause
the cruise control to disengage. Do not use
the cruise control on slopes, rough terrain
or while trimming or turning.
• With forward drive pedal depressed to
desired speed, pull cruise control lever
(J) up and hold while lifting your foot off
the pedal, then release the lever.
To disengage the cruise control, depress the
brake pedal, tap on forward drive pedal or
push the cruise control lever down.
TO ADJUST MOWER CUTTING HEIGHT
The position of the attachment lift lever (A)
determines the cutting height.
• Put attachment lift lever in desired cutting
height slot.
The cutting height range is approximately 1
to 4" (25,4 to 101,6 mm). The heights are
measured from the ground to the blade tip
with the engine not running. These heights
are approximate and may vary depending
upon soil conditions, height of grass and
types of grass being mowed.
• The average lawn should be cut to approxi-
mately 2-1/2" (63,5 mm) during the cool
season and to over 3" (76,2 mm) during
hot months. For healthier and better look-
ing lawns, mow often and after moderate
growth.
• For best cutting performance, grass over
6" (152,4 mm) in height should be mowed
twice. Make the first cut relatively high; the
second to desired height.
