Electrical System Safety
V Remove key, disconnect the negative (black) battery
cable from batteries and read owner’s manual before
adjusting or repairing unit.
V Always remove key and disconnect the negative (black)
battery cable from batteries before working on this unit.
V Always disconnect the negative (black) battery cable
from batteries when transporting unit.
V Keep unit free of grass clippings, leaves and other debris.
DO NOT spray water to clean unit. Use only compressed
air. Wear adequate eye and hearing protection when
cleaning the unit.
V Always wear safety glasses and protective gear near bat-
tery. Use insulated tools.
V Clean battery compartment, drive motor compartment,
mower deck, seat etc. of all dirt and debris. Do not spray
unit with water. Do not use, solvents, hard cleaners or
abrasives. Use only compressed air.
V Avoid injury. With key in ON position mower blade can
engage when deck clutch switch is engaged, even if drive
motor is not turning. Keep area clear of bystanders when
engaging clutch switch.
V All maintenance and storage areas should be properly
ventilated in accordance with applicable fire codes and
ordinances to avoid fire hazards. Proper ventilation is
required to remove hydrogen gas from the area dur-
ing battery charging.
The amount of hydrogen gas emitted depends on several
factors such as; battery charger output rate, battery charge
time and battery condition. Because of the highly volatile
nature of hydrogen gas and its propensity to rise and
accumulate at the ceiling in pockets, a minimum of 5 air
changes per hour is recommended. Consult applicable
fire and safety codes for the specific ventilation levels
requirement, as well as requirements for the use of explo-
sion proof electrical apparatus.
V Never allow flames, sparks or smoking near batteries.
V Keep batteries out of reach of children.
V Always keep protective shields, covers and guards in
place and securely fastened. If they become damaged,
repair or replace immediately. Never modify or remove
safety devices.
Electrical System Information

®
Zeon mower is powered by a 48 volt electrical
system. It consists of the following components:
1. Traction controller (2)
2. Deck controller (1)
3. Deck Motor (2)
4. Contactor (1)
5. Accelerator - right (1)
6. Accelerator - left (1)
7. Digital display (1)
8. Integrated electric transaxle (2)
9. 12 volt rechargeable battery (4)
Component Maintenance
IMPORTANT: Maintenance for the various electrical
components found on the Hustler
®
Zeon should only be per-
formed by a Hustler
®
Zeon trained technican.
Digital Display
The function of the digital display, located on the control
panel, is to provide electrical system information to the operator.
It gives detailed information in the form of operating codes and
system troubleshooting codes. It also provides battery charge
status by way of a LED battery level indicator.
Battery Charge Level Indicator
When the key is in the ON position the charge indicator LED
will light, indicating the relative charge remaining in the
batteries. When the batteries are fully charged LED 10 or 9 will
be lit. Fig. 5-1
During operation the lit LED will change, moving down the
indicator scale as the batteries discharge.
When battery charge is nearly depleted LED 1 and 2 will flash
alternately.
NOTE: The battery level indicator will reset once the batter-
ies have been fully charged.
IMPORTANT: When battery voltage becomes low, the
mower blades will stop, although the drive motors will continue
to run. When the batteries discharge to this point they require
recharging. The unit should immediately be returned to the
battery charging area and the unit connected to the battery
charger. The traction drive will continue to operate for a short
