2.1 HOW TO OPERATE SAFELY
SAFE OPERATION
a Read the Operator’s Manual and other training
material. If the operator or technician can not read
this manual, the owner is responsible to describe
this material to the operators and technicians.
Manuals in additional languages may be available
on the Jacobsen or RansomesJacobsen website.
a Read all of the instructions for this mower carefully.
Know the controls and the correct operation of the
equipment.
b Children or persons who do not understand these
instructions must not use the mower. The local
regulations can limit the age of the operator.
c Never use a mower near persons, including
children or animals.
d Remember that the operator or owner is
responsible for accidents or hazards that occur to
other persons or their property.
e Never carry passengers.
f Never allow persons to operate or service the
mower or its attachments without correct
instructions.
g Do not operate equipment while tired, sick or after
you use alcohol or drugs.
PREPARATION
a When you operate the mower, wear correct
clothing, slip resistant work shoes or boots, work
gloves, hard hat, safety glasses and hearing
protection. Long hair, loose clothing or jewelry can
be caught in moving parts.
b Do not operate the equipment with the Interlock
System disconnected or the system does not
operate correctly. Do not disconnect or prevent the
operation of any switch.
c Never operate equipment that is not in correct
order or without decals, guards, shields, deflectors
or other protective devices fastened.
d Inspect the mower before you operate the mower.
Check the tire pressure, engine oil level, the
radiator coolant level and the air cleaner indicator.
Fuel is flammable. Use caution when you add the
fuel to the mower.
e Operate the mower in daylight or in good artificial
light. Use caution when you operate the mower
during bad weather. Never operate the mower with
lightning in the area.
f Inspect the area to select the accessories and
attachments that are needed to correctly and safely
do the job. Only use parts, accessories and
attachments approved by Jacobsen.
g Be careful of holes in the terrain and other hazards
that are not visible.
h Inspect the area where the equipment is operated.
Remove all objects you can find before you
operate. Be careful of obstructions above the
ground (low tree limbs, electrical wires) and also
underground obstacles (sprinklers, pipes, tree
roots). Enter a new area carefully. Look for possible
hazards.
i Inspect the cutting system before you start the
mower. Make sure the blades are free to rotate.
When you rotate one blade, other blades can
rotate.
OPERATION
a Never operate the engine without enough
ventilation or in an enclosed area. The carbon
monoxide in the exhaust fumes can increase to
dangerous levels.
b Never carry passengers. Keep other persons or
animals away from the mower.
c Disengage all drives and engage the parking brake
before you start the engine. Only start the engine
with the operator in the seat. Never start the engine
with persons near the mower.
d Keep your legs, arms and body inside the operator
compartment while the mower is in operation. Keep
your hands and feet away from the cutting units.
WARNING
EQUIPMENT OPERATED INCORRECTLY OR WITHOUT TRAINING CAN BE DANGEROUS.
Know the location and correct operation of controls. Operators without experience must receive instruction from
another person that knows the correct operation of the equipment before you operate the mower.
Only use parts, accessories and attachments approved by Jacobsen.
!
SAFETY 2
5
e Do not use on the slopes greater than the safe
slope limit for the equipment.
f To guard against over turning or loss of control:
Operate the mower up and down on the face of
slopes (vertically), but not across the face
(horizontally).
Do not start or stop suddenly on slopes.
Decrease the speed when you operate on slopes
or when you must turn. Use caution when you
change direction. Turf condition can change the
mower stability.
Use caution when you operate the mower near
drop-offs, ditches or embankments.
Be careful of holes in the terrain and other hazards
that are not visible.
g When you drive in the reverse direction, look
behind you and down to make sure the path is
clear. Do not operate the cutting units when you
drive in the reverse direction.
h Use caution when you go near corners, trees or
other objects that can prevent a clear view.
i Equipment must meet the current regulations to be
driven on the public roads.
j Before you move across or operate on the paths or
roads, turn off the PTO switch, lift the mowers and
travel at decreased speed. Look for traffic.
k Stop the blades when the mower is on any surface
that is not grass.
l Do not release the cut grass in the direction of
persons or allow persons near the mower while in
operation.
m Do not operate the mower with damaged guards or
without safety devices in position.
n Do not change the engine governor setting or over-
speed the engine. Never change or tamper with
adjusters that are closed with a seal for the engine
speed control.
o Before you leave the operator compartment, for
any reason:
Disengage all the drives and lower attachments to
the ground.
Engage the parking brake.
Stop the engine and remove the key.
p When you hit an object or mower starts to cause
the vibration that is not normal, inspect the mower
for damage and make repairs.
q Decrease the throttle setting before you stop the
engine.
r Do not use this equipment for uses that the mower
was not made for.
ROPS
a The ROPS is a safety device. Keep the ROPS in
the vertical and locked position. Always use the
seat belt when you operate the mower. Make sure
the seat belt can be released quickly in an
emergency.
b Only operate the mower with the ROPS in the
folded position on flat and level surfaces when
necessary. Do not operate the mower with the
ROPS in the folded position on slopes, near sharp
edges or near water. There is no roll over
protection with the ROPS in the folded position.
c Check for clearance before you drive below
objects. Do not contact tree branches, electrical
wires or other objects with the ROPS.
d Do not use the seat belt with the ROPS in the
folded position.
e Inspect the ROPS for damage. Keep the ROPS
hardware fastened.
f Do not weld, drill, change or bend the ROPS.
Replace a damaged ROPS. Do not try to correct a
damaged ROPS.
g Do not remove the ROPS from the mower.
h Jacobsen must approve any changes to the ROPS.
SAFE HANDLING OF FUELS
a The fuel and the fuel vapors are flammable. Use
caution when you add the fuel to the mower. The
fuel vapors can cause an explosion.
b Never use the containers that are not approved to
keep or transfer fuel.
c Never keep the mower or fuel containers near an
open flame or any device that can cause the
ignition of fuel or fuel vapors.
d Never fill the fuel containers inside a vehicle or on a
truck or trailer with a plastic liner. Always put the
fuel container on the ground away from your
vehicle before you fill the container.
e Refuel the mower before you start the engine.
When the engine is in operation or while the engine
is hot, never remove the fuel cap or add fuel to the
mower.
f Refuel outdoors only and do not smoke when you
add fuel. Extinguish all types of ignition.
2 SAFETY
6
g The fuel nozzle must touch the rim of the fuel tank
when you add fuel to the mower. Do not use a
device to lock the fuel nozzle in the open position.
h Do not over fill the fuel tank. Leave at least 1 inch
(25 mm) below the filler neck.
i Always tighten the fuel tank cap and container cap
after you add fuel.
j If the fuel spills on your clothing, change your
clothing immediately.
MAINTENANCE AND STORAGE
a Before you clean, adjust or repair this equipment,
push PTO switch to the OFF position, lower the
cutting unit to the ground, engage the parking
brake, stop the engine and remove the key.
b Make sure the mower is parked on a solid and level
surface.
c Never work on a mower that is lifted only by the
jack. Always use the jack stands.
d Never allow persons to service the mower or its
attachments without correct instructions.
e When the mower is parked, put into storage or left
without an operator, lower the cutting device unless
a positive mechanical lock is used.
f When you put the mower on a trailer or put the
mower in storage, close the fuel valve. Do not keep

i Disconnect the battery charger from the power
supply before you connect or disconnect the
battery charger to the battery. Wear protective
clothing and use insulated tools when you service
the battery.
j Be careful and wear gloves when you check or
service the cutting unit blades. Replace any
damaged blades, do not try to correct a damaged
blade.
k Keep your hands and feet away from parts that
move. Do not adjust the mower with the engine in
operation, unless the adjustment needs the engine
in operation.
l Carefully release the pressure from components
with stored energy.
m To prevent injury from the hot, high pressure oil,
never use your hands to check for oil leaks. Use
the paper or cardboard to find leaks.
n The hydraulic fluid pressure can have enough force
to enter your skin. If hydraulic fluid has entered
your skin, a doctor must remove the hydraulic fluid
surgically within a few hours or gangrene can
occur.
oWhen you service the hydraulic system, make sure
the hydraulic fittings, tubes and hoses are
tightened to the correct torque. Make sure the
hydraulic system is in good condition before you
start the engine.
p Keep the mower and the engine clean.
q Allow the engine to become cool before storage
and always remove the ignition key.
r Keep all nuts, bolts and screws tight to make sure
the equipment is in safe condition.
s Replace worn or damaged parts for safety.
Replace damaged or worn decals. Only use parts,
accessories and attachments approved by
Jacobsen.
t To decrease the fire hazard, remove materials that
burn from the engine, muffler, battery tray and fuel
tank area.
u Disconnect the battery and controller connectors
before you weld on this mower.
WHEN YOU PUT THE MOWER ON A
TRAILER
a Be careful when you load or unload the mower on
a trailer. Trailer must be wider than the mower and
can carry the weight of the mower.
b Use a full-width ramp to load or unload the mower
on a trailer.
c Use straps, chains, cables or ropes to fasten the
mower to the trailer. Both front and rear straps
must be sent down and toward sides of trailer.
d Make sure that all latches are correctly fastened.

6.2 INTERLOCK SYSTEM ______________________________________________________
1. The Interlock system prevents the engine from
starting unless the parking brake is engaged, the
traction lever is in Neutral and the reel levers are off.
The system also stops the engine if the operator
leaves the seat with the reel levers on, traction lever
out of Neutral, or parking brake disengaged.
2. Perform each of the following tests to insure the
Interlock system is functioning properly. Stop the
test and have the system inspected and repaired if
any of the tests fail as listed below:
the engine does not start in test 1;
the engine does start during tests 2, 3 or 4;
the engine continues to run during tests 5 or 6.
3. Refer to the chart below for each test and follow the
check () marks across the chart. Shut engine off
between each test.
Test 1: Represents normal starting procedure. The
operator is seated, parking brake is engaged, the
traction lever is in Neutral, and the reel levers are off.
The engine should start.
Test 2: The engine must not start if the reel lever is in
Forward or Reverse. Repeat test for each reel lever
and lever position.
Test 3: The engine must not start if the parking brake
is disengaged.
Test 4: The engine must not start if traction lever is
not in Neutral. Repeat test for each position of lever.

6.3 OPERATING PROCEDURES ______________________________________________________
1. Under no circumstances should the engine be
started without the operator seated on the mower.
2. Do not operate mower or attachments with loose,
damaged, or missing components. Whenever
possible mow when grass is dry.
3. First mow in a test area to become thoroughly
familiar with the operation of the mower and control
levers.
4. Study the area to determine the best and safest
operating procedure. Consider the height of the
grass, type of terrain, and condition of the surface.
Each condition will require certain adjustments or
precautions. Only use accessories and attachments
approved by Jacobsen.
5. Never direct discharge of material toward
bystanders, nor allow anyone near the machine
while in operation. The owner/operator is
responsible for injuries inflicted to bystanders and/or
damage to their property.
6. Use discretion when mowing near gravel areas
(roadway, parking areas, cart paths, etc.). Stones
discharged from the implement may cause serious
injuries to bystanders and/or damage the
equipment.
7. Always move reel levers to Off position to stop
blades when not mowing.
8. Move reel levers to Off position and raise the reels
when crossing paths or roadways. Look out for
traffic.
9. Stop and inspect the equipment for damage
immediately after striking an obstruction or if the
machine begins to vibrate abnormally. Have the
equipment repaired before resuming operation.
10. Slow down and use extra care on hillsides. Read
Section 6.7. Use caution when operating near drop
offs.
11. Look behind and down before backing up to be sure
the path is clear. Use care when approaching blind
corners, shrubs, trees, or other objects that may
obscure vision.
12. Never use your hands to clean cutting units. Use a
brush to remove grass clippings from blades. Blades
are extremely sharp and can cause serious injuries.
WARNING
A Roll Over Protection Structure (ROPS) is included with this mower. Seat belts must be worn whenever operating
a mower with a ROPS. Always keep seat belt snugly adjusted. DO NOT use seat belts on a mower without a ROPS.
If the mower is overturning, hold onto the steering wheel. Do not attempt to jump out or leave the seat.

CAUTION
To help prevent injury, always wear safety glasses, leather work shoes or boots, a hard hat, and ear protection.
!
NOTICE
To prevent damage to the reel and bedknife never
operate the reels when they are not cutting grass.
Excessive friction and heat will develop between the
bedknife and reel and damage the cutting edge.
CAUTION
Before mowing, pick up all debris such as rocks, toys,
and wire which can be thrown by the machine. Enter a
new area cautiously. Always operate at speeds that
allow you to have complete control of the mower.
!

6.6 TO DRIVE / TRANSPORT____________________________________________________
Read and follow all safety notes contained in this manual
when driving or transporting mower. Refer to Section 6.3
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 all drives and raise implements to the
transport position when driving to and from the area
of operation.
2. Disengage parking brake and move traction lever to
Transport (2). Depress accelerator pedal slowly.
6.7 HILLSIDE OPERATION _____________________________________________________
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.
1. 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.
2. 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 - 10-12 psi (0.69-0.83 BAR)
Rear - 8-10 psi (0.55-0.69 BAR)
Figure 6B
Figure 6C
CAUTION
To prevent tipping or loss of control, travel at reduced
speed when making turns.
!
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 unnecessary
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
12.5° (22.1% grade).
