Indicator Panel Features
Battery Indicator
Illuminates and the battery voltage is displayed briefly when the
ignition switch it turned to the “ON” position.
Illuminates to indicate the battery voltage has dropped below
11.5 (+0.5/-1.0) 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 dealer.
Oil Pressure Indicator
This warning lamp indicates low engine oil pressure. If the
indicator comes on while the engine is running, stop the engine
immediately and check for possible causes. Do not run the
engine while this indicator is illuminated. Contact your dealer to
have the tractor and engine inspected.
NOTE:
The oil pressure indicator may illuminate when the
ignition switch is in the ON position, but should turn off when
the engine is started.
PTO Engaged Indicator
This indicator illuminates when the PTO switch is pulled upward
in the “ENGAGED” position and the ignition switch is turned
to the “START” position. Check this indicator if the engine will
not crank with the ignition switch in the “START” position. If
necessary, move the PTO switch to the “DISENGAGED” position.
Parking Brake Engaged Indicator
This indicator illuminates when the parking brake is in the
DISENGAGED position and the ignition switch is turned to the
“START” position. Check this indicator if the engine will not crank
with the ignition switch in the “START” position. If necessary,
move the parking brake to the ENGAGED position.
This indicator also illuminates when the ignition switch is turned
to the “START” position and the RH and/or LH drive control levers
are in a position other than the fully out in neutral position. Move
the control levers fully outward.
Throttle/Choke Control
The throttle/choke control is located on the LH console
to the left of the operator’s seat. When set in a given
position, a uniform engine speed will be maintained.

slow position.
ZT50
Push the throttle/choke control handle forward to increase
the engine speed. The tractor is designed to operate with the
throttle/choke control in the fast position (full throttle) when the
tractor is being driven and the mower deck is engaged.
Pull the throttle/choke control handle rearward to decrease the
engine speed.
Model ZT42 ONLY
— When starting the engine, push the
control handle fully forward into the “CHOKE” position. See
Figurere 8. After starting and warming the engine, move the
control handle rearward until you feel it move past the choke
detent.
Choke Control - Model ZT50 ONLY
The choke knob controls the position of the engine choke. Pull
the knob out to choke the engine; push the knob in to open the
choke.
Parking Brake Engagement Lever
The parking brake engagement lever is located on the
front/left of the seat box frame, and is used to engage the
parking brake.
Pull the lever fully upward and to the left; then lower into
the short “J” slot to engage the brake.
Pull the lever up out of the “J” slot and to the right; then
lower completely to disengage the parking brake.
NOTE:
If the LH and RH drive control levers are not fully
opened out in the neutral position when engaging the
parking brake, the engine will stop. The parking brake
must be placed in the engaged position when starting the
tractor engine.
Transmission Oil Expansion Reservoir
The transmission oil expansion reservoir is connected by hoses to
the RH and LH transmission assemblies, and is located beneath
the seat box. The function of the reservoir is to hold the natural
expansion of transmission oil that occurs as the transmission
warms up during operation. DO NOT FILL THE RESERVOIR.
Under normal operating conditions, no oil should be added
to the reservoir. The COLD oil level should be no higher than
approximately 1⁄4
” (the “Full Cold” mark) above the bottom of the
reservoir.
NOTE:
Prior to the initial operation of the tractor, the oil level in
the reservoir may be slightly higher than the maximum due to air
in the oil lines. Operation of the tractor will eventually purge the
air from the lines and the oil level will settle to the maximum.
