operation, and displays the information on the LCD hour meter display
(tenths of an hour - rightmost digit). The monitor also has four indicator
lights that show the status of various functions of the tractor.

The system indicator monitor features are as follows:
LCD Hour Meter Display
The hour meter display is activated when the key switch is turned to
either the “NORMAL MOWING” or the “REVERSE CAUTION MODE”
switch positions. When the key switch is turned to an on position,
the battery indicator light briefly illuminates and the battery voltage is
briefly displayed. The display then changes to the accumulated hours.
NOTE: A record of the actual hours of operation should be kept to
assure maintenance procedures are completed according to the
schedule in this manual.
The Indicator Monitor will also remind the operator of maintenance
intervals for changing the engine oil. The LCD will alternately flash
the recorded hours, “CHG” and “OIL” tor five minutes, after every 50
hours of recorded operation elapse. The maintenance interval lasts for
two hours (from 50-52, 100-102, 150-152, etc.). The LCD will flash as
described for five minutes every time the tractor's engine is started dur­
ing this maintenance interval. Follow the oil change intervals provided
in the Service & Maintenance section of this Manual.
Battery Indicator Light
This indicator illuminates when the ignition switch it turned to an ON
position and the engine is not started.
This also illuminates to indicate the battery voltage has dropped below
11.5 (■+-0.5/-1.0) DC volts (the battery voltage is also displayed on the
hour meter). If this indicator and display come on during operation,
check the battery and charging system for possible causes and/or
contact your Sears Parts & Repair Service Center.
Oil Pressure Indicator Light
This warning lamp indicates low engine oil pressure. If this indicator
illuminates, stop the tractor immediately and check the engine oil level.
If the oil level is within the operating range, but the light remains on,
contact your Sears Parts & Repair Service Center.
NOTE: The oil pressure indicator may illuminate when the key switch is
turned to an on position, but should turn off when the engine is started.
PTO (Power Take-Off) Engaged Indicator Light
This indicator illuminates when the key switch is turned to the “START”
position while the PTO knob is in the “ENGAGED” position. Check this
indicator it the engine will not crank with the key switch in the “START”
position. Move the PTO knob to the “DISENGAGED” position.
Brake Engaged Indicator
This indicator illuminates when the key switch is turned to the “START”
position and the brake pedal is not fully depressed. Check this
indicator it the engine will not crank with the key switch in the “START”
position. If necessary, fully depress the brake pedal.
THROTTLE CONTROL LEVER
The throttle control lever controls the speed of
the engine. When set in a given position, the
throttle will maintain a uniform engine speed.
IMPORTANT: When operating the tractor with
the cutting deck engaged, the throttle control
lever must always be in the FAST (rabbit)
position.
KEY SWITCH MODULE
The key switch module is used to
start and stop the engine. It is also
used to activate the Reverse Caution
Mode (blades operate while riding
in reverse). Insert key into the key
switch module and turn clockwise to
the START position. Release the key
into the normal mowing position once
engine has started.
To stop the engine, turn the ignition
key counterclockwise to the STOP
position.
