PDU _______________________________________________________________
The PDU is located to the left of the operator seat, under the MCU, and is used to switch 48V and 12V motor/controller
outputs on or off. Three circuit breakers are located on the rear of the PDU.
Before working on, or opening the PDU, shut mower off, remove key, disconnect 48 volt battery connector, and discon
-
nect 12 volt battery connector (Hybrid mowers). Use caution to prevent shorting between PDU input, output, and ground
cable studs.
Inside the PDU are the following components:
•
Traction Contactor - Used to control 48 volt power out -
put to TCU and OLM.
• 48 Volt Contactor - Used to control 48 volt power output
to MCU, RCU, SCU, and other components.
• 12 Volt Relay - Used to control 12 volt power output to
MCU, 12 volt lights, and engine components.
• 150 Amp Fuse - Used to provide circuit protection for 48
volt contactor.
• 300 Amp Fuse - Used to provide circuit protection for
traction contactor.
• 12 Amp Circuit Breaker - Used to provide circuit protect
for 48 volt contactor output except for RCU and SCU.
• 30 Amp Circuit Breaker - Used to provide circuit protec -
tion for SCU.
• 50 Amp Circuit Breaker - Used to provide circuit protec -
tion for 12 volt contactor.
• Printed Circuit Board - Used for controlling PDU inputs
and outputs.

TRACTION PEDAL TEST ______________________________________________
Check traction pedal adjustment if mower is not maintaining correct speeds.
1. Obtain optional pedal test connector
(AS) (Part Number
4225240). Connect test connector to main harness and
traction pedal.
2. Turn mow switch to RUN position. Do not start mower.
3. Measure voltage using White and Black wires on test
connector (AS) . If test connector is not used, measure
directly at Orange and Black wires in pedal connector,
pins 2 and 3.
4. Press pedal for full forward movement. The voltage
should read 4.5V.
5. Press the pedal for full rear movement. The voltage
should read 0.5V.
6. Move the pedal to the neutral location. The voltage should read 2.5V.
7. Remove test connector
(AS) .
