1 SAFETY
1.1 OPERATING SAFETY ______________________________________________________
1. Safety is dependent upon the awareness, concern
and prudence of those who operate or service the
equipment. Never allow minors to operate any
equipment.
2. It is your responsibility to read this manual and all
publications associated with this equipment (Safety &
Operation Manual, Engine Manual, and attachments/
accessories instruction sheets). If the operator
cannot read English it is the owner’s responsibility to
explain the material contained in this manual to them.
3. Learn the proper use of the machine, the location
and purpose of all the controls and gauges before
you operate the equipment. Working with unfamiliar
equipment can lead to accidents.
4. Never allow anyone to operate or service the
machine or its attachments without proper training
and instructions; or while under the influence of
alcohol or drugs.
5. Wear all the necessary protective clothing and
personal safety devices to protect your head, eyes,
ears, hands, and feet. Operate the machine only in
daylight or in good artificial light.
6. Evaluate the terrain to determine what accessories
and attachments are needed to properly and safely
perform the job. Only use accessories and
attachments approved by Jacobsen.
7. Stay alert for holes in the terrain and other hidden
hazards.
8. Inspect the area where the equipment will be used.
Pick up all the debris you can find before operating.
Beware of overhead obstructions (low tree limbs,
electrical wires, etc.) and also underground obstacles
(sprinklers, pipes, tree roots, etc.). Enter a new area
cautiously. Stay alert for hidden hazards.
9. Never direct discharge of material toward bystanders,
nor allow anyone near the machine while in
operation. The owner/operator can prevent and is
responsible for injuries inflicted to themselves, to
bystanders, and damage to property.
10. Do not carry passengers. Keep bystanders and pets
a safe distance away.
11. Never operate equipment that is not in perfect
working order or is without decals, guards, shields,
discharge deflectors, or other protective devices
securely fastened in place.
12. Never disconnect or bypass any switch.
13. Do not change the engine governor setting or
overspeed the engine.
14. Carbon monoxide in the exhaust fumes can be fatal
when inhaled. Never operate the engine without
proper ventilation or in an enclosed area.
15. Fuel is highly flammable; handle with care.
16. Keep the engine clean. Allow the engine to cool
before storing and always remove the ignition key.
17. Disengage all drives and engage parking brake
before starting the engine (motor). Start the engine
only when sitting in operator’s seat, never while
standing beside the unit.
18. Equipment must comply with the latest federal, state,
and local requirements when driven or transported
on public roads. Watch out for traffic when crossing
or operating on or near roads.
19. Local regulations may restrict the age of the operator.
20. Never use your hands to search for oil leaks.
Hydraulic fluid under pressure can penetrate the skin
and cause serious injury.
21. Operate the machine up and down the face of slopes
(vertically), not across the face (horizontally).
22. To prevent tipping or loss of control, do not start or
stop suddenly on slopes. Reduce speed when
making sharp turns. Use caution when changing
directions.
23. Always use the seat belt when operating mowers
equipped with a Roll Over Protective Structure
(ROPS).
Never use a seat belt when operating mowers
without a ROPS.
24. Always disconnect battery cables from battery before
performing any welding operation on the mower.
This machine is to be operated and maintained as specified in this manual and is intended for the professional
maintenance of specialized turf grasses. It is not intended for use on rough terrain or long grasses.
WARNING
EQUIPMENT OPERATED IMPROPERLY OR BY UNTRAINED PERSONNEL CAN BE DANGEROUS.
Familiarize yourself with the location and proper use of all controls. Inexperienced operators should receive
instruction from someone familiar with the equipment before being allowed to operate the machine.

3 ADJUSTMENTS

3 ADJUSTMENTS
3.1 GENERAL________________________________________________________________
1. Adjustments and maintenance should always be
performed by a qualified technician. If proper
adjustment cannot be made, contact an authorized
Jacobsen Dealer.
2. Replace, do not adjust, worn or damaged
components.
3. Long hair, jewelry, or loose fitting clothing may get
tangled in moving parts.
4. Do not change governor settings or overspeed the
engine.
3.2 BEDKNIFE-TO-REEL _______________________________________________________
(Pre-adjustment Check)
1. Check the reel bearings for end play or radial play.
There should be no end play or radial play. See
Section 3.14.
2. Inspect the reel blades and bedknife to insure good
sharp edges without bends or nicks.
a. The leading edge of the reel blades (B) must be
sharp, free of burrs and show no signs of rounding
off.
b. The bedknife and bedknife backing must be
securely tightened. The bedknife must be straight
and sharp.
c. A flat surface of at least 1/16 in. (1.5 mm) minimum
must be maintained on the front face of the bed-
knife. Use a standard flat file to dress the bedknife.
3. If wear or damage is beyond the point where the
reel or bedknife can be corrected by the lapping
process, they must be reground.
4. Proper reel-to-bedknife adjustment is critical. A gap
of 0.001 to 0.003 in. (0.025 to 0.076 mm) must be
maintained across the entire length of the reel and
bedknife.
5. 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.
6. Grass conditions will also affect the adjustment.
a. Dry, sparse conditions will require a wider gap to
prevent heat buildup and damage to the reel and
bedknife.
b. High quality grass with a good moisture content
requires a closer gap (near zero).
Figure 3A
Figure 3B
WARNING
To prevent injury, lower implements to the ground,
disengage all drives, engage parking brake, stop
engine and remove key from ignition switch before
making any adjustments or performing maintenance.
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.
If only the front or rear of the mower is raised, place
chocks in front of and behind the wheels that are not
raised.
!
CAUTION
Be careful to prevent entrapment of the hands and
fingers between moving and fixed components of the
machine.

3.3 BEDKNIFE ADJUSTMENT ___________________________________________________
1. Read Section 3.2 before making the adjustment.
2. 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.
3. Use adjusters (A and B), to adjust gap. Loosen
bottom adjuster (B) and turn top adjuster (A) down
(Clockwise) to close gap.
a. Slide a feeler gauge or shim stock 0.001 - 0.003
in. (0.025 - 0.076 mm) between the reel blade
and the bedknife. Do not turn the reel.
b. Adjust the trailing end of the reel to the same
gap in a similar manner then recheck the
adjustment at the leading end.
c. 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.
Figure 3C
Note: Avoid excessive tightening or serious damage may
result to bedknife and reel blades. Reels must turn freely.
3.4 CUTTING HEIGHT _________________________________________________________
Note: Always make the bedknife to reel adjustment
before adjusting height of cut. (See Sections 3.2 and
3.3).
1. Raise mowers to transport position then engage the
parking brake, stop engine, and remove key from
ignition switch.
2. Set desired cutting height on the gauge (I).
a. Measure distance (J) between the underside of
screw head and gauge block surface.
b. Adjust screw (F) to obtain desired height then
tighten the wing nut.
3. Loosen the locknuts on the front roller brackets (E)
just enough to allow the adjuster knob (H) to raise or
lower the front roller.
4. Place gauge (I) across bottom of front and rear
rollers near one end of roller.
5. Slide the head of gauge screw over the bedknife (G)
and adjust the knob (H) to close the gap between the
screw head and bedknife. Then tighten locknut (E).
6. Repeat Steps 4 and 5 on opposite end. Complete
adjustment to one end before adjusting opposite end.
7. Tighten locknuts (E) and recheck each end.

3.6 ACCELERATOR PEDAL ____________________________________________________
1. The top of the pedal should not be less than 2-3/4
in. (70 mm) from the floorboard when pedal is fully
depressed.
2. Loosen locknut (D) and adjust carriage bolt (E) to
obtain the correct distance between pedal and
floorboard.
Figure 3F
3.7 BRAKE PEDAL____________________________________________________________
1. Drive straight forward with traction lever in MOW
position and throttle in SLOW position. Depress
Brake pedal. If the brake pedal comes too close to
the floorboard, check the amount of brake lining left.
a. Replace lining.
b. Adjust nut (F) to obtain a distance of 3-5/16 in.
(84 mm), between rod pivot points, (when brakes
are new), and to compress spring to 31/32 in. (24
mm).
2. If machine pulls right, turn adjusting nut (F) on left
side clockwise. If machine pulls left, turn adjusting
nut (F) on left side counterclockwise. Do not
compress either spring past 7/8 in. (22 mm).

with the ground, adjust torsion spring (Z).
2. Carefully loosen spring mounting clamp and slowly
turn clamp until implement is level. Tighten clamp
securely.
Figure 3L
3.14 REEL BEARING ___________________________________________________________
Excessive end play or any radial play indicates bad
bearings, a weak tension spring, or a backed off nut.
1. Check bearing housing mounting hardware. Tighten
or replace components as required. Carefully clean
threads with degreaser.
2. Apply a medium strength grade of Loctite to nut (AA),
then thread nut onto the reel shaft until the nut is
1-27/32 in. (46 mm) from the end of the reel shaft.
3. Fill reel bearing housings with NLGI - Grade O
grease after adjusting spring.
Figure 3M

a maintenance schedule and keep detailed records.
a. Keep the equipment clean.
b. Keep all moving parts properly adjusted and
lubricated.
c. Replace worn or damaged parts before operating
the machine.
d. Keep all fluids at their proper levels.
e. Keep shields in place and all hardware securely
fastened.
f. Keep tires properly inflated.
3. Long hair, jewelry, or loose fitting clothing may get
tangled in moving parts.
4. Use the illustrations in the Parts Catalog as
reference for the disassembly and reassembly of
components.
5. Recycle or dispose of all hazardous materials
(batteries, fuel, lubricants, anti-freeze, etc.)
according to local, state, or federal regulations.
4.2 ENGINE _________________________________________________________________
IMPORTANT: A separate Engine Manual, prepared by
the engine manufacturer, is supplied with this
mower. Read the Engine Manual carefully until you
are familiar with the operation and maintenance of
the engine. Proper attention to the engine
manufacturer’s directions will assure maximum
service life of the engine. To order a replacement
Engine Manual contact the engine manufacturer.
The proper break-in of a new engine can make a
considerable difference to the performance and life of the
engine.
Note: The mower is designed to operate and cut most
efficiently at the preset governor setting. Do not change
the engine governor settings or overspeed the engine.
During the break-in period, Jacobsen recommends the
following:
1. During the first 50 hours of operation, a new engine
should be allowed to reach an operating temperature
of at least 140°F (60°C) prior to operation at full load.
2. Check the engine oil level twice daily during the first
50 hours of operation. Higher than normal oil
consumption is not uncommon during the initial
break-in period.
3. Change engine oil and oil filter element after first 50
hours of operation.
4. Check and adjust fan and alternator belts.
5. Refer to Section 6.3 and Engine Manual for specific
maintenance intervals.
If the injection pump, injectors, or the fuel system require
service, contact an authorized Jacobsen Dealer.
WARNING
Before you clean, adjust, or repair this equipment,
disengage all drives, lower implements to the ground,
engage parking brake, stop engine, and remove key
from ignition switch 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.

4.3 ENGINE OIL ______________________________________________________________
Check the engine oil at the start of each day, before
starting the engine. If the oil level is low, remove oil filler
cap and add oil as required.
Perform initial oil change after first 50 hours of operation
and every 75 hours thereafter. See Engine Manual.
Use only engine oils with API classification CD/CE.
Figure 4A
4.4 DIESEL AIR FILTER ________________________________________________________
Check the service indicator daily. If red band appears in
the window (C) replace the element.
Do not remove the element for inspection or
cleaning. Unnecessary removal of the filter increases
the risk of injecting dust and other impurities into the
engine.
When service is required, first clean the outside of the
filter housing; then remove the old element as gently as
possible and discard.
1. Carefully clean the inside of the filter housing without
allowing dust into the air intake.
2. Inspect the new element. Do not use a damaged
element and never use an incorrect element.
3. Assemble the new element and make sure it seats
properly. Reset the indicator by depressing button
(D).
4. Reassemble cap making sure it seals completely
around the filter housing. Dust evacuator must be
facing down.
5. Check all hoses and air ducts. Tighten hose clamps.
