TO USE THROTTLE CONTROL (D) (See Fig.7)
Always operate engine at full speed (fast).
• Operating engine at less than full speed (fast) reduces
the engine's operating efficiency.
• Full speed (fast) of fers the best mower per for mance.
D
TO MOVE FORWARD AND BACKWARD
(See Fig. 8)
The direction and speed of movement is controlled by the
forward and reverse drive pedals.
• Start tractor and release parking brake.
• 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) (See Fig. 8)
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
con di tions such as trimming at slow speeds may cause the
cruise control to dis en gage. 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
or tap on forward drive pedal.

TO USE DIFFERENTIAL LOCK CONTROL (Y)
(See Fig. 9)
• To engage differential lock, stop the tractor and push
the differential lock switch to the "ON" position.
NOTE: Driving for long periods of time with the differential
lock engaged is not detrimental or abusive to the system.
CAUTION: To minimize the risk of dam-
age, avoid engaging differential lock while
vehicle is in motion.
• Drive tractor forward. As the rear tires rotate the
differential lock will engage.
NOTE: Operators may notice displacement or turfing of
grass in turns with differential lock engaged.
• To disengage differential lock, push differential lock
switch to the "OFF" position. If the differential lock
does not disengage, steering the vehicle from side to
side will assist.
TO ADJUST MOWER CUTTING HEIGHT
(See Fig. 10)
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 ap prox i mate ly 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 approximately
2-1/2" (63,5 mm) during the cool season and to over 3"
(76,2 mm) during hot months. For healthier and better
looking 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 de sired height.
