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
Textron Turf Care And Specialty Products 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.
3.1 PARKING/SERVICE BRAKE _________________________________________________
Inspect brakes linings:
whenever wheels are pulled,
if tractor creeps on hills with parking brake applied,
there is a noticeable increase in stopping distance.
The brakes used on this tractor are self-adjusting. To
adjust, apply brakes while operating in reverse. If brakes
linings look good but brakes cannot be self-adjusted, it
may be necessary to adjust brake cable. If linings or
brake drums appear worn, they should be replaced by an
experienced service technician.
To adjust brake cable:
1. Raise tractor and support axle using jack stands or
blocks so that back wheels are slightly raised off the
ground. Block front wheel to make sure unit can’t roll.
2. Raise hood and remove battery tray to access brake
pull assembly (A).
3. Back off jam nut (B).
4. With the brake pedal all the way up (disengaged)
turn in adjusting nut (C) and spin wheels slowly by
hand until you feel brakes engage and wheels begin
to bind.
5. Back off adjuster nut slightly until wheels again turn
freely.
6. Tighten jam nut to lock adjustment in place.
7. Check that plugs (D) are in place in slotted holes on
equalizer bracket.
Before returning unit to operation, drive tractor in a flat,
open area and check operation of brakes to make sure
they are operating correctly. Check parking brake to
make sure it engages properly and prevents the tractor
from rolling downhill.
Figure 3B
WARNING
To prevent injury, lower implements to the ground,
disengage all drives, engage parking brake, turn off
power, remove key from switch and disconnect power
connector before making any adjustments or
performing maintenance.
Make sure the tractor is parked on a solid and level
surface. Never work on a tractor that is supported
only by the jack. Always use jack stands.
If only the front or rear of the tractor is raised, place
chocks in front of and behind the wheels that are not
raised.

3.2 BRAKE SWITCH ___________________________________________________________
The brake pedal is equipped with a proximity switch. This
switch closes when the brake is engaged. If the operator
leaves the seat without engaging the brake the switch
remains open and will automatically shut the power off.
The switch consists of two pieces, a stationary sensor (J)
and a magnet (K) that pivots with the brake pedal. A
faulty or loose switch can prevent the unit from starting.
For correct operation, adjust air gap (I) between magnet
and sensor to 1/16” - 3/32” (1.5 - 2 mm).
Figure 3C
3.3 FORWARD/REVERSE SWITCH _______________________________________________
(neutral adjustment)
If error codes “-02”or“-03” occur repeatedly the forward/
reverse switch for the traction controller could be out of
adjustment.
To adjust forward/reverse switch:
1. Lift hood and remove top cover from electrical box.
2. Operate forward/reverse pedals and check that
cable linkage is operating smoothly. If cable is
binding, or linkage is bent or damaged, contact an
authorized Jacobsen Dealer for repairs.
3. Remove screw (E) holding cable end to forward/
reverse switch lever.
4. Back off nut (F) which secures rod end (H) to cable.
5. With the cable disconnected, the switch lever (G)
should return to its neutral position. Adjust rod end
on cable so it aligns directly with hole in lever.
Note:
If the alignment appears correct but the error
code continues to occur, the forward/reverse switch
may be faulty. Contact an authorized Jacobsen
Dealer for repairs.

4 BATTERI ES
4.1 SAFETY__________________________________________________________________
Batteries contain dilute sulfuric acid which can result in severe burns.
Hydrogen gas is formed within a battery during the charging cycle. Hydrogen in concentrations of 4% and higher are
explosive and can be ignited by open flame or an electrical spark. A battery explosion will cause sulfuric acid and
battery components to be thrown over a large area with considerable force.
Always observe the following warnings when working on or near batteries:
4.2 GENERAL ________________________________________________________________
Temperature is important when conducting tests on a
battery and test results must be corrected to compensate
for temperature differences.
As a battery ages, it still performs adequately except that
its capacity is diminished. Capacity describes the time
that a battery can continue to provide its design amperes
from a full charge.
The batteries most commonly used in golf and utility
vehicles are lead acid.
A battery has a maximum life, therefore good
maintenance is designed to maximize the available life
and reduce the factors that can reduce the life of the
battery.
WARNING
The electrolyte in a storage battery
is a dilute acid which can cause
severe burns to the skin and eyes.
Treat all electrolyte spills to the body
and eyes with extended flushing
with clear water. Contact a physician
immediately. Always wear a safety
shield or approved safety goggles when adding water
or charging batteries.
Hydrogen is explosive in concentrations as low as 4%
and is generated in the charging cycle of electric
vehicles. Because it is lighter than air, it will collect in
the ceiling of buildings necessitating proper
ventilation. Air exchanges of 5 changes per hour is
considered the minimum requirement.
Never smoke around batteries.
Never charge batteries in an area that has open flame
or electrical equipment that could cause an electrical
arc.
Be sure that the key switch is off and all electrical
accessories are turned off before starting work on
vehicle.
Remove all jewelry (watches, ring etc.)
!
TR016
WARNING
Wrap wrenches with vinyl tape to
prevent the possibility of a dropped
wrench from ‘shorting out’a battery,
which could result in an explosion and
severe personal injury.
Use care not to tip batteries when
removing or installing them; spilled
electrolyte can cause burns and damage.
Electrolyte spills should be neutralized with a solution
of 1/4 cup (59.1ml) of sodium bicarbonate (baking
soda) dissolved in 1-1/2 gallons (5.7 liters) of water
and flushed with water.
Overfilling a battery could result in electrolyte being
expelled from the battery during the charging cycle.
Electrolyte may cause personal injury, damage to the
vehicle or damage to the storage facility.
Overfilling the batteries will void the vehicle and
battery warranties.
Never disconnect a circuit under load at a battery
terminal.
Wear appropriate protective clothing when working
with batteries. Electrolyte can cause severe burns to
the eyes, skin and clothing.
Batteries are heavy. Use proper lifting techniques
when moving them. Always lift the battery with a
commercially available battery lifting device

Tool List
Insulated wrench, 9/16”
Insulated wrench, 1/2”
Battery carrier
Hydrometer
Before charging batteries
Inspect the connector housing of the battery charger and
vehicle connector housing for dirt or debris.
Charge the batteries daily after use.
Monthly
1. Inspect all wiring for frayed wire, loose connections,
corrosion or deterioration of insulation.
2. Check that the electrolyte level is correct and add
suitable water as required.
3. Clean the batteries and cable terminals.
4.4 ELECTROLYTE LEVEL AND WATER__________________________________________
The correct level of the electrolyte is at least 1/2”(13
mm) above the plates in each cell.
A battery being charged will ‘gas’, with the majority of the
gassing taking place at the end of the charging cycle.
This gas is hydrogen which is lighter than air. Water and
sulfuric acid droplets will be carried out of the battery
vents by the hydrogen gas; however, this loss is minimal.
If the battery electrolyte level is too high, the electrolyte
will block the vent tube and the gas will force it out of the
vent tube and battery cap. The water will evaporate but
the sulfuric acid will remain where it can damage vehicle
components. Sulfuric acid loss will weaken the
concentration of acid within the electrolyte and reduce
the life of the battery.
This level will leave approximately 1/4”-3/8”(6 - 10 mm)
of space between the electrolyte and the vent tube. The
electrolyte level is important since any portion of the
plates exposed to air will be ruined beyond repair. Of
equal importance is too much water which will result in
electrolyte being forced out of the battery due to gassing
and the increase in volume of the electrolyte that results
from the charging cycle.
Over the life of the battery, a considerable amount of
water is consumed. It is important the water used be pure
and free of contaminants that could reduce the life of the
battery by reducing the chemical reaction. The water
must be distilled or purified by an efficient filtration
system. Water that is not distilled should be analyzed and
if required, filtration installed to permit the water to meet
the requirements of the water purity table.

WARNING
Never attach a battery charger to a vehicle that is to
be unattended. A charger failure could cause damage
to the vehicle batteries and result in extreme
overheating.

Water Purity Table
Even if the water is colorless, odorless, tasteless and fit
for drinking, the water should be analyzed to see that it
does not exceed the impurity levels specified in the table
above.
Automatic watering devices such as the one shown can
be used with an approved water source. These watering
devices are fast and accurate to use and maintain the
correct electrolyte level within the battery cells. Figure 4F
4.7 CLEANING BATTERIES_____________________________________________________
When cleaning the batteries, do not use a water hose
without first spraying with a solution of sodium
bicarbonate (baking soda) and water to neutralize any
acid deposits.
Use of a water hose without first neutralizing any acid,
will move acid from the top of the batteries to another
area of the vehicle or storage facility where it will attack
the metal structure or the concrete/asphalt floor. After
hosing down the batteries, a residue will be left on the
batteries which is conductive and will contribute to the
discharge of the batteries.
The correct cleaning technique is to spray the top and
sides of the batteries with a solution of sodium
bicarbonate (baking soda) and water. This solution is
best applied with a garden type sprayer equipped with a
non metallic spray wand. The solution should consist of
1/4 cup (59.1 ml) of sodium bicarbonate (baking soda)
mixed with 1-1/2 gallons (5.7 l) of clear water. In addition
to the batteries, special attention should be paid to
metallic components adjacent to the batteries which
should also be sprayed with the sodium bicarbonate
(baking soda) solution.
Allow the solution to sit for at least three minutes; use a
soft bristle brush or cloth to wipe the tops of the batteries
in order to remove any residue that could cause the self
discharge of the battery. Rinse the entire area with low
pressure clear water. Cleaning should take place once a
month or more often under extreme conditions.

4.9 BATTERY INSTALLATION __________________________________________________
If the batteries have been cleaned and any acid in the
battery rack area neutralized, no corrosion to the battery
racks or surrounding area should be present. Any
corrosion found should be immediately removed with a
putty knife and a wire brush. The area should be washed
with a solution of sodium bicarbonate (baking soda) and
water and thoroughly dried before priming and painting
with a corrosion resistant paint.
The batteries should be placed into the battery racks and
the battery hold downs (Views A & B) tightened snugly
to prevent movement, but not tight enough to cause
distortion of the battery cases.
Inspect all wires and terminals. Clean any corrosion from
the battery terminals or the wire terminals with a solution
of sodium bicarbonate (baking soda) and brush clean if
required.
Use care to connect the battery wires as shown in
Figure 4J and tighten the battery post hardware securely.
Protect the battery terminals and battery wire terminals
with a commercially available protective coating.
Refer to Section 2.3 for battery specifications.

4.11 BATTERY CHARGING______________________________________________________
The battery charger is designed to fully charge the
battery set. If the batteries are severely deep cycled,
some automatic battery chargers contain an electronic
module that may not activate and the battery charger will
not function. Automatic chargers will determine the
correct duration of charge to the battery set and will shut
off when the battery set is fully charged. Always refer to
the instructions of the specific charger used.
Before charging, the following should be observed:
The electrolyte level in all cells must be at the
recommended level and cover the plates.
The charging must take place in an area that is well
ventilated and capable of removing the hydrogen gas that
is generated by the charging process. A minimum of five
air exchanges per hour is recommended.
The charging connector components are in good
condition and free from dirt or debris.
The charger connector is fully inserted into the vehicle
receptacle.
The charger connector/cord set is protected from
damage and is located in an area to prevent injury that
may result from personnel running over or tripping over
the cord set.
The charger is automatically turned off during the
connect/disconnect cycle and therefore no electrical arc
is generated at the DC plug/receptacle contacts.
AC Voltage
Battery charger output is directly related to the input
voltage. If multiple vehicles are receiving an incomplete
charge in a normally adequate time period, low AC
voltage could be the cause and the power company
should be consulted.
WARNING
Aerosol containers of battery terminal protecting must
be used with extreme care. Insulate the metal
container to prevent the metal can from contacting
battery terminals which could result in an explosion.

4.12 TROUBLESHOOTING_______________________________________________________
In general, troubleshooting will be done for two distinct
reasons. First, a battery that performs poorly and outside
of the manufacturers specification should be identified in
order to replace it under the terms of the manufacturer’s
warranty. Different manufacturers have different
requirements. Consult with the battery manufacturer for
specific requirements.
The second reason is to determine why the tractor does
not perform adequately. Performance problems may
result in a tractor that runs slowly or in a tractor that is
unable to operate as long as it previously did.
A new battery must
mature before it will develop its
maximum capacity. Maturing may take up to 100 charge/
discharge cycles. The older a battery gets, the lower the
capacity. The only way to determine the capacity of a
battery is to perform a load test using a discharged
machine.
A cost effective way to identify a poorly performing
battery is to use a hydrometer to identify a battery in a set
with a lower than normal specific gravity. Once the
particular cell or cells that are the problem are identified,
the suspect battery can be removed and replaced. At this
point there is nothing that can be done to salvage the
battery; however, the individual battery should be
replaced with one of the same brand, type and
approximate age that is known to be good.
4.13 HYDROMETER ____________________________________________________________
Hydrometers are used to test the state of charge of a
battery cell. This is performed by measuring the density
of the electrolyte, which is accomplished by measuring
the specific gravity of the electrolyte. The greater the
concentration of sulfuric acid, the more dense the
electrolyte becomes. The higher the density, the higher
the state of charge.
Specific gravity is the measurement of a liquid that is
compared to a baseline. The baseline is water which is
assigned a base number of 1.000.
The concentration of sulfuric acid to water in a new
battery is 1.280 which means that the electrolyte weighs
1.280 times the weight of the same volume of water.
A
fully charged battery will test at 1.275 - 1.280 while a
discharged battery will read in the 1.140 range.
Note:
Do not perform a hydrometer test on a battery that
has just been watered. The battery must go through at
least one charge and discharge cycle in order to permit
the water to adequately mix with the electrolyte.
The temperature of the electrolyte is important since the
hydrometer reading must be corrected to 80°F(26.7°C).
High quality hydrometers are equipped with an internal
thermometer that will measure the temperature of the
electrolyte and will include a conversion scale to correct
the float reading. It is important to recognize that the
electrolyte temperature is significantly different from the
ambient temperature if the vehicle has been operated.
Using a Hydrometer (Figure 4N)
1. Draw electrolyte into the hydrometer several times to
permit the thermometer to adjust to the electrolyte
temperature and note the reading. Examine the color
of the electrolyte. A brown or gray coloration indi-
cates a problem with the battery and is a sign that the
battery is nearing the end of its life.
2. Draw the minimum quantity of electrolyte into the
hydrometer to permit the float (B) to float freely
without contacting the top or bottom of the cylinder
(E).
3. Hold the hydrometer in a vertical position at eye
level and note the reading where the electrolyte
meets the scale on the float.
4. Add or subtract four points (.004) to the reading for
every 10°F(6°C) above or below 80°F(27°C).
See Examples 1 and 2. Adjust the reading to
conform with the electrolyte temperature.
5. E.g. If the reading indicates a specific gravity of
1.250 and the electrolyte temperature is 90°F(32°
C), add four points to the 1.250 which gives a
corrected reading of 1.254. Similarly if the
temperature was 70°F(21°C), subtract four points
from the 1.250 to give a corrected reading of 1.246.
WARNING
Never insert a metal thermometer into a battery. Use a
hydrometer with a built in thermometer that is
designed for testing batteries.
!

16
6. Test each cell and note the readings (corrected to
80°For27°C). A variation of fifty points between
any two cell readings (example 1.250 - 1.200)
indicates a problem with the low reading cell(s).
7. As a battery ages the specific gravity of the
electrolyte will decrease at full charge. This is not a
reason to replace the battery, providing all cells are
within fifty points of each other.
8. Since the hydrometer test is in response to a vehicle
exhibiting a performance problem, the vehicle
should be recharged and the test repeated. If the
results indicate a weak cell, the battery or batteries
should be removed and replace with one of the
same brand, type and approximate age that is
knowntobegood.

4.15 PROLONGED STORAGE ____________________________________________________
During periods of storage, the batteries will need
attention to keep them maintained and prevent
discharge.
In high temperatures the chemical reaction is faster, while
low temperatures cause the chemical reaction to slow
down. A vehicle that is stored at 90°F(32°C) will
lose.002 of specific gravity each day. If a fully charged
battery has a specific gravity of 1.275, and the battery is
allowed to sit unused, it will become partially discharged.
When it reaches 1.240 which it will do in less than twenty
days, it should be recharged.
If a battery is left in a discharged state, sulfation takes
place on and within the plates. This condition is not
reversible and will cause permanent damage to the
battery. In order to prevent damage, the battery should be
recharged. A hydrometer can be used to determine the
specific gravity and therefore the state of charge of a
battery.
In winter conditions, the battery must be fully charged to
prevent the possibility of freezing. A fully charged battery
will not freeze in the most severe of winter climates.
Although the chemical reaction is slowed in cold
temperatures, the battery must be stored fully charged,
and disconnected from any circuit that could discharge
the battery. Disconnect the charging plug from the vehicle
receptacle. The batteries must be cleaned and all
deposits neutralized and removed from the battery case
to prevent self discharge. The batteries should be tested
or recharged at thirty day intervals.
