2 SAFETY
WARNING
California Proposition 65
Engine exhaust, some of its constituents, and some vehicle components contain or release chemicals known to
the state of California to cause cancer and birth defects or other reproductive harm.
WARNING
To prevent injury from the hot oil at high pressure, DO NOT use your hands to check for oil leaks.
Make sure that you use paper or cardboard.
Release of hydraulic fluid at high pressure has enough force to enter through the skin. If the fluid enters
through the skin, you must seek medical attention immediately.
WARNING
When the machine is driven off-road, a seat belt must be worn only when a ROPS frame is in position.
This warning is because a seat belt must be worn with a ROPS to follow the Machinery Directive,
2006/42/EC Sections 3.2.2, Seating & 3.4.3, Rollover. (ANSI B71.4-2012 section 20.7)
Ransomes Jacobsen Limited recommends that the owner/user of the machine completes a site specific risk
assessment of the machine to find any conditions that do not follow this rule.
e.g. when you drive the machine next to water.
WARNING
Explosive gases are released by batteries. The battery contains corrosive acid and supplies an electrical
current that is high enough to cause injuries to the body.
WARNING
You must not use this machine to tow other vehicles.
WARNING
Ear protection must be worn when you operate machines with
an operator ear noise level of more than 85dB(A) Leq
!

SAFETY 2
WARNING
Vibration Exposure Limits
Exposure limits are calculated as a combination of the vibration level (magnitude) of the tool and the Daily
Exposure Time (Trigger Time). e.g. A product with 5m/s² vibration can be used up to 2 hours/day
to reach the EAV and up to 8 hours/day to reach the ELV.
Exposure Action Value (EAV) - Daily vibration exposure A(8) = 2.5m/s²
Where daily vibration exposure A(8) is below 2.5m/s² the risk is relatively low and no
action need be taken.
Exposure Limit Value (ELV) - Daily Vibration Exposure A(8) = 5.0m/s²
If several tools are use the exposure values must be combined:
Total exposure is then the combined value of the activities.
WARNING
Never mow if there is a risk of lightning or you hear thunder. If you are in the middle of mowing, stop in a safe
place, turn off the engine and go inside a building.
CAUTION
When you do any welding on the machine, the battery, controller and display must be disconnected before
you start. You must not open the controller. If the controller is opened, this can void all of the warranties and
can cause the failure of the machine
CAUTION
Personal Protective Equipment (PPE), for example safety glasses, safety footwear, work gloves
and ear protection must be used after the owner/user completes a site specific risk assessment of the
mower to prevent injury.

6.7 CUTTING CYLINDER LIFT & LOWER RATE & SYNCHRONISATION ______________
The valves that control the rate and sequence in which the
Cutting Units rise and fall are set at the factory, however they
can be reset or altered using the following steps.
1. Start the machine and run the engine at full throttle for
15-20 minutes to ensure that the oil is at the optimum
temperature.
2. To set up sequencing lift/lower of the front & rear unit.
Open all three valves fully. Screw the single front unit
adjuster (C) in until the rate of lift/lower is acceptable.
3. Use the two rear valves the upper valve (A) for lower
and the lower valve (B) for lift to provide the
sequencing of the Centre unit.
4. Cycle the cutting units to check the synchronisation.
The Centre Cutting Unit should lower and lift slightly
after the front Cutting Units.
If the cylinders drop too quickly or are not
synchronised correctly then they should be adjusted
accordingly.
The upper valve (A) at the rear of the machine adjusts
the rate at which the Centre Cutting Unit lowers.
The lower valve (B) at the rear adjusts the rate at
which the Centre Cutting Unit lifts.
The valve (C) under the operators seat adjusts the
rate at which the front Cutting Units lower.
5. If it is not possible to get the sequencing of the rear Cutting Unit correct this may be because the front
cutting units are set to lower too slowly. Try increasing the speed of drop slightly.
6. Once the Cutting Units are lifting and lowering correctly tighten each of the Grubscrews found on the valves
to lock the settings.

6.9 STARTING THE ENGINE _________________________________________________
The following procedure is for starting cold engines.
1. Ensure the FWD/REV pedal is in the neutral position, the mow switch is off, the throttle setting is in a mid
position.
2. Turn the ignition switch fully clockwise and hold until the engine starts (approximately 5-10 sec.)
3. The glow plugs are auto timed depending on the coolant temperature for operating the starter motor (This
should only take a few seconds)
4. When the engine starts, release the key immediately and it will return to the RUN position.
5. If the engine does not start, return key to the OFF position and try again.
NOTES:
• If the engine fails to start after two attempts, wait 20 seconds and try again.
• The starter motor should never be run continuously for longer than 30 seconds or it may fail.
• If the red LED’s on the display flash whilst starting one of the safety interlock switches has not been set
correctly.
6.10 DRIVING _____________________________________________________________
• Release brake - Make sure the parking brake is released before attempting to go forward or reverse.
• Forward - Gently depress the top A of the FWD/REV foot pedal to reach desired ground speed.
• Reverse - Gently depress the bottom B of the FWD/REV foot pedal to reach desired ground speed.
• To stop - Gently return the FWD/REV foot pedal to the neutral position.
• To hold the vehicle stationary on a slope it may be necessary to apply a certain amount of reverse traction.
NOTES:
• Use complete foot to operate both forward and reverse.
• Do not move pedal suddenly–always operate slowly and smoothly. Never move pedal violently from
forward to reverse or vice versa.
• Always keep foot firmly on the foot pedal–a too relaxed foot control may result in a jerky motion.
6.11 MOWING PROCEDURE_________________________________________________
NOTE: Always remove the flag and inspect the green before mowing. Remove debris or other objects that may
damage the reels and/or Bedknives. Operators should practice mowing in a clear area to become familiar with
raising and lowering the mowing heads. They should be aware that the centre cutting head raises and lowers
slightly later than the front ones, allowing the centre cut to begin and end at the same point as the two side cuts.
Practising 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.
Several factors may determine the direction of the mowing pattern, sand traps or other hazards near the green,
trees etc that 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. Make sure the reel enable switch is in the "ON" position and
the mow / transport lever is in position 1 (mow). Proceed onto the green at mowing speed and lower the
mowing heads as the front grass catchers cross the leading edge of the green. At the end of the pass, raise
the heads as the front grass catchers cross the trailing edge of the green.
2. Always make mowing passes across the green in a straight line. DO NOT start to make the turn for the next
pass until the rear wheel is completely off the green, this will eliminate the possibility of the tires tearing the
turf during the turn.
3. Each successive pass should overlap the previous one by two or three inches (51 or 76mm) (a painted
en 44
6 OPERATION
mark two or three inches (51 or 76mm) in from the outer edges of the two front grass catchers will help
align each overlapping pass).
4. 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.
5. With the engine stopped or the reel enable switch in the "OFF" position, empty the grass catchers before
proceeding to the next green.
6.12 HOW TO STOP THE ENGINE_____________________________________________
1. Disengage drive to the Cutting Units with the Cutting Unit Switch.
2. Return the FWD/REV pedal to the neutral position.
3. Set the parking brake.
4. Move the throttle control lever to the SLOW position.
5. Turn the ignition key to OFF
6.13 HOW TO REMOVE A BLOCKAGE FROM CUTTING UNITS ____________________
1. Disengage the power to the cutting units with the cutting unit switch.
2. Keep the cutting units lowered to the ground (Wait for the remaining cutting cylinders to stop rotation).
3. Lift the cutting units into the “Transport Position”, lock in position use the transport latches fitted on your product.
4. Remove your foot from the forward/reverse pedal.
5. Set the parking brake.
6. Move the throttle control lever to the slow position.
7. Turn the ignition key to the off position and remove the key
NOTICE
To avoid damage to the green, NEVER stop the forward motion of the mower on the green with the reels
turning. Stopping the mower on a wet green may cause wheel indentations.
CAUTION
It is important to note: there will be remaining hydraulic pressure within the system that can cause
the cutting cylinder to rotate when the obstruction is removed. Therefore keep your hands, feet
and clothing away from Cutting Units at all times.
NOTICE
Make sure correctly selected PPE is worn before you clear the obstruction.
!

OPERATION 6
8. Use the Jacobsen “Cutting Unit Tool” part number 4184540 See below or stout stick, put into the cutting
cylinder between the blades
9. Rotate the cylinder with either the “Cutting Unit Tool” or “Stout Stick” until the obstruction has been removed.
10. Inspect all the cutting surfaces for damage, when necessary replace the damaged components.
6.14 BACKLAPPING_______________________________________________________
This mower is fitted with the ability to allow the reels to be driven in reverse for backlapping.
• Backlapping is a process which will lightly grind the reel to the bedknife whilst mounted on the mower.
• If significant amounts of metal are to be removed then the cutting unit should be reground on a specialised
grinding machine.
• Before any backlapping is carried out, Ransomes Jacobsen recommends that the backlapping process
should be risk assessed as a workshop process by the manager of the machine.
• Backlapping should only be carried out by trained staff.
• Ransomes Jacobsen recommend that grinding paste is only applied to the reel when it is stationery, the
engine is off and the parking brake applied.
• When applying grinding paste the reel should only be rotated by appropriately sized piece of wood and not
by hand.
• Place reels in the most accessible position for applying the paste.
• After applying the grinding paste the person backlapping should return to the seat, engage the relevant
controls and run the reels in reverse.
• When the desired finish is achieved switch off the mower, clean off any surplus paste, reset the reel to
bedknife and return the controls to the normal mow positions.

6.15 BACKLAPPING PROCEDURE____________________________________________
Before starting the backlap procedure, release the Centre Unit and swing it out. The backlap valve is located
under the seat plate on the right hand side. It can be accessed from under the machine when the Centre Unit
is swung out
1. Apply an even coat of backlapping compound to the entire length of each blade of the reels.
2. While pressing the centre red button (A) on the reel valve pull yellow plunger (B) away from the valve.
3. Start the engine and set the throttle to low idle. Lower heads by operating the Joystick or paddle.
4. Slowly turn the restriction valve knob (C) clockwise until the desired reel rotation speed is attained. It should
be slow enough so that the reel will not throw off the backlapping compound as it spins.
5. Once all the blades on the reel are uniformly sharp, shut off the engine and push yellow plunger (B) back
towards the valve. Set the reel speed valve (C) to mow speed.
6.16 TRANSPORTING ON A TRAILER OR FLATBED _____________________________
The machine has hard-point tie-down loops front (A) and rear (B). Fasten the mower to the transport vehicle.
Make sure that all tie down straps are tight. Make sure that the
decks are locked in the transport position. Check the fuel and
hydraulic tank caps are tight. Make sure that no part of the mower
can fall during transport.
Always follow the given maximum transport load weight for the
vehicle used.
DO NOT carry more than the maximum weight shown on the
transport vehicle plate.
Always read the safety and operation manual of the transport vehicle before you load.
6.17 SLINGING AND JACKING THE MACHINE __________________________________
Slinging
When slinging the machine use the tie down loops front and rear.

OPERATION 6
6.18 MOWING ON SLOPES __________________________________________________
The mower has been designed for good traction and
stability under normal mowing conditions. Use caution
when operating on slopes, especially when the grass is
wet. Wet grass reduces traction and steering control.
1. Always mow with the engine at full throttle, control
forward speed using traction foot pedal to maintain
proper cutting.
2. Use weight transfer control as required to improve
weight distribution between decks and mower.
3. If the mower tends to slide or the tyres begin to mark
the turf, angle mower into a less steep slope until
traction is regained or tyre marking stops.
4. If mower continues to slide or mark the turf, the slope
is too steep for safe operation. Do not make another
attempt to climb, and back down slowly.
5. When descending a steep slope, always lower
implements to the ground to reduce the risk of
mower overturning.
Correct tyre pressure is essential for maximum
traction. See 3.2 Specification.
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. To ensure best stability always load
the left hand storage rack first and cut with all
three units powered.

operated properly.
7.16 LUBRICATION OF CUTTING UNIT ______________________________________
Cleaning
The cutting heads should be washed after use each days and dried as well as possible to prevent rust.
Lubrication
The lubrication fittings at each end of both the front and rear rollers, as well as the reel bearings at each end
should be lubricated periodically (approximately once each week). Use only enough lubricant to keep the
bearings from drying out. Too much lubricant may drop from mower onto turf, causing damage to the grass.
NOTICE
When washing machine with pressure spray washers or steam cleaners, avoid washing bearing areas
because cleaning solutions might penetrate bearing seals and cause premature bearing failure.

8.1 TRACTION CONTROL PEDAL___________________________________________
ADJUSTING MOW SPEED
To determine mow speed, run a time check on how fast the
unit travels in a distance of 50’ (15.24 M). Prepare a level
surface with enough room to start and end beyond the 50’
marks.
Place a stake in the ground where you want to begin timing
the unit. Measure and place another stake at a distance of
50’ (15.24 M). Lower the cutting heads and press the direc-
tion pedal forward so the unit is traveling at full throttle (the
cutting heads should be in the neutral position when timing
the unit).
Begin timing the unit when the centre of the front tire aligns
with the first stake. Stop timing when the centre of the front
tire aligns with the stake placed at 50’ (15.24 M). Estimated
time for 3.8 mph (6.1 Km/hr) will be approximately 8.8 to 9.2
seconds. If there is a significant difference in the times listed
above, you can adjust the mow speed as follows.

Safety
Driver's seats that have been adjusted incorrectly have a smaller moving area. In order to prevent any personal
injury, the seat must be adjusted for the driver's weight.
To prevent injury, no objects should be placed within the moving area of the driver's seat.
To eliminate any risk of accident, the settings must be checked to ensure they are correctly engaged before the
vehicle is driven.
Adjustments must not be made While driving.
Only touch the handle for setting the fore/aft adjustment at the indented grip provided for that purpose (do not put
your whole hand around it). Risk of crushing.
After removal of the backrest upholstery, the backrest frame must be supported, for example held in place, before
the backrest adjuster is operated. If you fail to do so, there is a danger that the backrest frame may jerk forward
and cause injury.
Any changes to the series standard of the seat (for example fitting parts which are not original Grammer AG parts)
may impair the safety standard to which it has been tested. Functions may be impaired, threatening your safety.
For this reason, any changes in design of the seat must be approved by Grammer AG.
Do not hold onto the covers for lifting the driver's seats. If you do so anyway, there is an increased risk injury due
to loosening or breaking covers.
Before you remove the driver’s seat, disconnect all plug-in connections between the seat and the vehicle supply
network. When you replace the plug-in connectors, make sure they are tight (dust, water).
Seatbelts are fitted or can be retrofitted to the driver’s seat. Seatbelts may only be fitted on approval of the vehicle
manufacture, as they increase the load in the seat mounting area. Seatbelts must be fitted in accordance with spe-
cific national regulations and guidelines, and must be approved by Grammer AG.
Seatbelts must be fastened before driving.
The seatbelts must be replaced after an accident.
Where seatbelts are fitted to the driver's seat, the seat and seatbelt mounting must be checked additionally by spe-
cialist personnel after an accident has occurred.
Fasteners must be checked regularly for tight seat. If the seat wobbles, there may be loose bolts or other faults.

8 ADJUSTMENTS
f you notice that the seat does not function correctly (for example a defective suspension of the driver's seat; im-
proper curvature of the lumbar support or damaged bellows), contact a specialist workshop immediately to arrange
for repairs to be carried out. If you fail to do so, your health may be affected and the risk of an accident increased.
Before the vehicle is used, switches that might be in the seat (for shutting down mechanical equipment when the
driver leaves his/her seat) must be checked for proper function. If malfunctions are detected, the vehicle must not
be driven.
Loads must not be placed on seats with a built in switch, except for the driver’s weight during normal use, as the
vehicle may otherwise start to move by itself. If you take off the weight from the seat while driving, this will cause
the vehicle to stop.
Do not indent the bellows while there is load on the driver’s seat.
Make sure that the interior of the drivers seat remains free of foreign objects or liquids.
Seat functions and operation
Weight adjustment
The seat is adjusted for the driver’s weight with the driver sitting on the seat. Fold out the weight adjustment lever
completely, hold it at the front and move it upwards or downwards (10 movements from minimum to maximum).
Before every new movement, bring the lever back to the starting position (audible locking sound). The driver’s
weight has been set correctly, when the arrow is in the middle of the viewing window.
• To prevent damage to the health and material, the setting for the driver’s weight must be checked and adjusted
as necessary before the vehicle is driven.
• When the minimum/maximum has been reached, you can
notice an empty movement in the handle.
• When you have set the weight, fold the lever completely
into the locking.

Fore/aft adjustment
The fore/aft adjustment is released by lifting the locking
lever.
• After the adjustment, the locking lever must latch into the desired position with an audible click. It should not
be possible to move the driver’s seat into another position when it is locked.
• Do not lift the locking lever with your leg or calf.
Lumbar support
The lumbar support increases both the seating comfort
and the performance of the driver. By turning the
adjustment knob upwards, the curvature in the upper part
of the backrest cushion can be adjusted. By turning the
knob downwards, the curvature in the lower part of the
backrest cushion can be adjusted.
0 = No curvature
1 = Max. curvature at the top
2 = Max. curvature at the bottom.
Backrest adjustment
Pull up the locking lever to release the backrest catch.
When releasing the backrest catch, do not apply load to
the backrest by pressing against it. By exerting pressure
on or off the front or rear part of the seat pan it can be
moved to the desired position. Release the locking lever to
lock the backrest.
• It should not be possible to move the backrest into
another position after it has been locked.

Armrests
The armrests can be folded back if required and the height in-
dividually adjusted. To adjust the armrests for height, sepa-
rate the round cap (see arrow) from the cover, loosen the
hexagon nut (size 13 mm) behind it and adjust the armrests
to the desired position (5-steps) and tighten the nut again
(25Nm). Replace the cap onto the nut.
Armrest adjustment
The inclination of the armrests can be modified by turning the
adjustment knob. When turning the knob to the outside (+) the
front part of the armrest will be lifted, when turning the knob
to inside (-) it will be lowered.
Maintenance
Dirt can impair the function of the seat, So make sure you
keep your seat clean. Upholstery does not need to be re-
moved from the seat frame for cleaning.
ATTENTION: Do not clean the seat with a pressure washer.
When cleaning the upholstery, make sure the upholstery is not soaked.
Use standard commercially available upholstery or plastics cleaning agent. Test first for compatibility on a small,
concealed area.
WARNING
If the belt roller is fitted, do not install the
armrest in the lowest position as otherwise
the belt roller might not function correctly.
Carry out a functional test of the belt roller.
CAUTION
Take care with the backrest - it may jerk forward
and cause injury.

DANGER
When the machine is being used off road,
whether cutting grass or not, the seat belt
should only be worn when a ROPS frame is in
place and deployed.
This rationale is based on the fact that a seat
belt must be worn with a ROPS to comply with
the Machinery Directive 98/37/EC Sections
3.2.2, Seating & 3.4.3, Rollover.
Ransomes Jacobsen Limited
recommends that a local risk
assessment is completed by the
owner / user of the machine to
determine any exceptions to this seat
belt wearing rule e.g. use of the
machine next to water or on
the highway.

8.7 BEDKNIFE-TO-REEL TRUESET™ 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 8.10.
2. Inspect the reel blades and bedknife to insure good sharp edges without bends or nicks.
a. The leading edge of the reel blades 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 1/32 in. (0.8 mm) minimum must be maintained on the front face of the bedknife.
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” (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).
CAUTION
To prevent personal injury and damage to the cutting edges, wear gloves and handle the reel
and bedknife with extreme care.

11.1 QUALITY OF CUT PROBLEM SOLVING __________________________________
If required perform a “test-cut” to assess the performance of the mower before you begin the repairs.
When the work is completed, repeat the “test-cut” to check the mower performance.
The following items must be checked and set correctly to make sure of an effective assessment.
1. Blade Sharpness
2. Blade Speed
3. Mowing (Ground) Speed
4. Height-of-Cut (HOC)
5. Rake Angle
6. Caster/Roller and Roller Bearing Condition
7. Tyre pressures
8. General wear and tear of the machine
11.2 STEP CUTTING______________________________________________________
NOTE: Arrow indicates direction of travel.
“Step cutting” occurs when the grass is cut higher on
one side. The cause is mechanical wear or incorrect
setting of the roller or deck caster.
Possible Cause Correction
The HOC (height-of-cut) settings are different on the
side of one cutting implement.
Check HOC adjustment of cutting implement
Worn roller bearings or deck caster wheels. Check and replace the roller bearings, deck
caster wheels.
Changes in turf density Change the direction of cut.

of-cut (HOC) setting, rough surface.
Possible Cause Correction
The HOC (height-of-cut) settings are low for the
conditions.
Check and adjust the HOC settings.
(See section 8.14)
The mower cannot follow the ground in this direction.
Change the direction of cut.
The height of grass is being reduced too much in one
