ELECTRONIC TRACTION CONTROL SYSTEM ____________________________
The Eclipse is equipped with an electronic traction control system which utilizes a controller and software to regulate
speed and optimize the driveability of the unit. A speed sensor in the drive motor reports the exact vehicle speed to the
controller which electronically controls the drive motor to maintain a smooth and constant speed whether the unit is going
uphill or downhill.
When the direction/speed pedal is returned to Neutral, the controller uses regenerative braking by essentially turning the
drive motor into a generator and putting energy back into the battery pack or automatically adjusting the engine throttle
on hybrid powered mowers to control proper generator output.
To prevent an over-voltage condition, any excess power created by the regenerative action is sent through the resistor
banks located on the right side of the machine. System voltage over 60 VDC could cause damage to the controllers.
PARKING BRAKE____________________________________________________
The Eclipse mower is equipped with a parking brake. When the parking brake is applied, the parking brake light on the
LDU will be lit. The parking brake is applied whenever the parking brake switch is ON.
To disengage parking brake: The parking brake will disengage when the parking brake switch is in the OFF position.
To engage parking brake: To engage the parking brake, move the parking brake switch on the console to the ON posi-
tion.

LIFT SYSTEM _______________________________________________________
The Eclipse 360 lift system operates in one of two modes, service mode and mow mode, depending on the position of
the mow switch (B).
Service Mode - Service mode is active with mow switch (B) in OFF (down) position and parking brake engaged. Service
mode is used to raise or lower the individual reels for servicing, without activating reel motors. Push forward on joystick
(J) to lower reels, or pull back on joystick to raise reels. Only reels with corresponding reel switches (C, D, or E) in the
ON position will lower.
If reels are lowered or in the crosscut position, mow switch is off, and mower starts moving, reels will automatically raise
to the transport position.
NOTICE
A ratcheting sound will come from the lift actuators
if joystick (J) is pulled back with reels fully raised.
The sound is produced by a clutch in the actuator,
and is designed to prevent damage to the actuator.
Mow Mode - Mow mode is active with mow switch (B) in ON (up) position. Reels will automatically lower to crosscut
position when mow switch is turned ON. Push forward and release joystick (J) to fully lower reels and activate reel
motors. Pull back on joystick and release to raise reels to crosscut position and deactivate reel motors. Pull back and
release a second time to fully raise reels to transport position.
Only reels with corresponding reel switches (C, D, or E) in the ON position will lower and activate reel motors. This
allows operation of one, two, or all three reels, depending on area to be cut or operation being performed (clean up pass,
etc.).
NOTE: When operating, depending on mower speed, there will be up to a two second delay before center reel
raises or lowers. See Center Reel Delay on page 49.
B
If reel(s) fail to raise in mow mode, or an error code appears in the LDU, stop mower, push down on mow switch (B), and
try to raise the reel in service mode. Return mower to the service area to have the lift system inspected.

OPERATION
TO DRIVE / TRANSPORT______________________________________________
Read and follow all safety notes contained in this manual when driving or transporting mower. See Operating Proce-
dures on page 46 for general operating instructions. When operating in reverse, look behind you to ensure you have a
clear path.
Important: If this mower is driven on public roads, it must comply with federal, state, and local ordinances.
Contact local authorities for regulations and equipment requirements.
1. Disengage mow switch. Reels will automatically raise to the transport position once mower starts moving.
2. Depress traction pedal slowly.
3. Move the parking brake switch to the OFF position. The parking brake should disengage and mower will start moving.
!
CAUTION
To prevent tipping or loss of control, travel at
reduced speed when making turns.
CENTER REEL DELAY _______________________________________________
The raising and lowering of the center reel is slightly delayed from the front reels. When mowing, this allows the center
reel to contact the ground at the same location as the front reels, resulting in an accurate cut.
The length of delay is automatically adjusted for any change in vehicle speed, which is determined by the speed sensor
in the drive motor. If the unit is not in motion or if there is no speed sensor signal, the center reel delay will default to a
time of approximately 2 seconds. There is no delay when lift system is in service mode (Mow switch is OFF).
B
OVERLOAD PROTECTION ____________________________________________
The reel drive motors and lift actuators are controlled by the RCU. The RCU has built–in overload protection and will disable the motor or actuator if it is drawing too much electrical current.
If there is an overload on a reel drive motor, the circuit breaker will trip, the motor will be disabled, the reel will raise to the
up position and the fault light on the LDU will flash two times per second.
If there is an overload on a lift actuator, the actuator will be disabled and the fault light on the LDU will flash two times per
second.
To reset an overload fault condition, the mower must be shut down and re-started. If the problem persists, inspect the
device and the electrical system to determine the cause of the overload or contact an authorized Jacobsen dealer.
MOWING ___________________________________________________________
!
WARNING
To prevent serious injuries, keep hands, feet, and
clothing away from reel when the blades are moving.
NEVER use your hands to clean reels. Use a brush
to remove grass clippings from blades. Blades can
be sharp and could cause injuries.
To clear obstructions from reel, turn mow switch
OFF, stop the mower, turn system power switch to
OFF, and remove key, then remove obstruction.
Lithium
Safety, Operation, & Maintenance Manual

OPERATION
NOTICE
B
Operators should practice mowing in a clear area to become familiar with raising and lowering the reels. Practicing, by
turning reel motors off (See Operator Mode on page 28), will help the operator become proficient at starting and stopping each pass within a foot or two of the edge of the green. Then only one final pass around the green will be required to
finish the operation.
To prevent damage to the reel and bedknife, never
operate reels when they are not cutting grass.
NOTICE
Always remove the flag and inspect the green
before mowing. Remove debris or other objects
that may damage the reels and/or bedknives.
Several factors may determine the direction of the mowing pattern. Sand traps or other hazards near the green and trees
or other objects can restrict where turns are made. The terrain of the green may also be a factor, but if conditions allow,
always try to mow the green in a different direction than the last time it was mowed.
1. Stop the unit just before reaching the green and raise the reels. Set the mow switch to ON.
2. Proceed toward the green at mowing speed. See Frequency of Cut on page 34 for matching mowing speed to desired Frequency of Cut.
3. Lower the reels as the front grass catchers cross the edge of the green. At the end of the pass, raise the reels as the just before grass catchers cross the edge of the green.
4. Always make mowing passes across the green in a straight line. Do NOT start to make the turn for the next pass until the center wheel is off the green, this will eliminate the possibility of the tires tearing the turf during the turn.
5. Each successive pass should overlap the previous one by a few inches.
6. After all of the straight passes have been made, make one final pass around the outer edge of the green. This final pass should always be in the opposite direction from the last time the green was mowed.
7. Empty the grass catchers before proceeding to the next green. To remove or install the grass catchers, turn mow
switch OFF, lower the reels to the ground, and shut off the unit. Tilt the grass catcher body so the front edge clears
the mower frame, and slide the catcher onto or off the catcher frame.
8. Stop and raise the mowers to the transport position when crossing paths or roadways. Look out for traffic.
en-50
NOTICE
To avoid damage to the green, NEVER stop the for-
ward motion of the mower while on the green with
the reels turning. Stopping the mower on a wet
green may cause wheel indentations.
NOTICE
When verticutting with the Eclipse 360 Jacobsen
recommends setting the reel speed at 1800 rpm. If
the reel motor temperature or current exceeds lim-
its, reduce ground speed of mower, reduce reel
speed, or adjust verticutter depth.

HILLSIDE OPERATION _______________________________________________
!
WARNING
To minimize the possibility of overturning, the safest
method for operating on hills and terraces is to
travel up and down the face of the slope (vertically),
not across the face (horizontally). Avoid unneces-
sary turns, travel at reduced speeds, and stay alert
for hidden hazards and drop offs.
!
CAUTION
Do not operate this mower on side slopes greater
than 17° or 31% grade.
The mower has been designed for good traction and stability under normal mowing conditions; however, use caution
when operating on slopes, especially over rough terrain or when the grass is wet. Wet grass reduces traction and steering control.
• If the mower tends to slide or the tires begin to “mark” the turf, angle mower into a less steep grade until traction is
regained or tire marking stops.
• If mower continues to slide or mark the turf, the grade is too steep for safe operation. Do not make another attempt
to climb, and back down slowly.
Correct tire pressure is essential for maximum traction.
• Front - 16 psi (1.11 BAR)
• Rear - 20 psi (1.38 BAR)

Charging should be performed when ambient temperatures are between 40°F and 110°F (4°C and 42°C). The battery
pack may be charged or topped off after every use.
The battery management system (BMS) and charger cooperate to make sure that charging occurs at the proper rate for
the battery temperature. When the battery charger is connected to the vehicle, it will determine the charge rate based on
the battery temperature. The charger will operate at the rates shown in the table below:
Charge Rate Temperature
NO charging below 14°F (-10°C) or above 140°F (60°C)
Pre-charge (charge at reduced rate, 21 amps) between 14°F (-10°C) and 41°F (5°C)
between 104°F (40°C) and 140°F (60°C)
Full charging between 37.4°F (3°C) and 107.6°F (42° C)
• The BMS will adjust the charge rate based on the temperature of the batteries.
• Use only the OEM approved Lithium-Ion battery charger for your vehicle. See charge operating instructions
for use.
• Turn the key to the OFF position and remove it from the vehicle.
• Inspect the charger cord for cracks, frayed wires or loose connections. If damaged, replace it.

GENERAL __________________________________________________________
!
WARNING
Before you clean, adjust, or repair this equipment,
disengage all drives, lower implements to the
ground, turn system power off, remove key from
ignition switch, and disconnect battery pack(s) to
prevent injuries
Make sure the mower is parked on a solid and level
surface. Never work on a mower that is supported
only by the jack. Always use jack stands.
• Adjustments and maintenance should always be performed by a qualified technician. If proper adjustment cannot be
made, contact an authorized Jacobsen Dealer.
• Replace, do not adjust, worn or damaged components.
• Long hair, jewelry or loose fitting clothing may get tangled in moving parts.
!
CAUTION
Be careful to prevent entrapment of the hands and
fingers between moving and fixed components of
the machine.
• Do not change speed limit settings or overspeed the drive motors.
B
BEDKNIFE-TO-REEL _________________________________________________
(Pre-adjustment Check)
• Check the reel bearings for end play or radial play. There should be no end play or radial play. See Torque Specification on page 86.
!
CAUTION
To prevent personal injury and damage to the cut-
ting edges, wear gloves and handle the reel and
bedknife with extreme care.
• Inspect the reel blades and bedknife to insure good
sharp edges without bends or nicks.
• The leading edge of the reel blades must be sharp,
free of burrs and show no signs of rounding off.
• The bedknife and bedknife backing must be securely
tightened. The bedknife must be straight and sharp.

ADJUSTMENTS
B
C
• A flat surface of at least 1/32 in. (0.08 cm) minimum
must be maintained on the front face of the bedknife.
Use a standard flat file to dress the bedknife.
B
• If wear or damage is beyond the point where the reel or
bedknife can be corrected by the lapping process, they
must be reground.
• Proper reel-to-bedknife adjustment is critical. A gap of
0.001 to 0.003” (0.0025 to 0.0076 cm) must be maintained across the entire length of the reel and bedknife.
• The reel must be parallel to the bedknife. An improperly
adjusted reel will lose its sharp edges prematurely and
may result in serious damage to the reel and bedknife.
• Grass conditions will also affect the adjustment.
• Dry, sparse conditions will require a wider gap to prevent heat buildup and damage to the reel and bedknife.
• High quality grass with a good moisture content requires a closer gap (near zero).
BEDKNIFE ADJUSTMENT _____________________________________________
• See Bedknife-To-Reel on page 77 before making the
adjustment.
• Start adjustment at the leading end of the reel, followed by
the trailing end. The leading end of the reel blades is that
end which passes over the bedknife first during normal
reel rotation.
• Use adjusters (B and C), to adjust gap. Rotate adjusters
(Clockwise) to close gap. Each click of the adjuster moves
the bedknife 0.001” (0.0025 cm) closer to the reel.
• Slide a feeler gauge or shim stock 0.001” - 0.003”
(0.0025 - 0.0075 cm) between the reel blade and the
bedknife. Do not turn the reel.
• Adjust the trailing end of the reel to the same gap in a
similar manner then recheck the adjustment at the
leading end.
• When the reel is properly adjusted to the bedknife, the
reel will spin freely and you should be able to cut a
piece of newspaper, along the full length of the reel,
when the paper is held at 90° to the bedknife.
