SAFETY PRECAUTIONS
This manual should be regarded as part of the machine, as it gives essential
information regarding machine safety, operation, maintenance and specications.
READ THIS MANUAL BEFORE USING THE LT3240 MOWER, IT IS
ESSENTIAL THAT OPERATORS STUDY IT FOR THEIR OWN SAFETY.
THE FOLLOWING PRECAUTIONS MUST BE TAKEN TO HELP PREVENT
ACCIDENTS. A CAREFUL OPERATOR WHO USES COMMON SENSE IS THE
SAFEST OPERATOR.
Training
Read the instructions carefully. Be familiar with the controls and the proper use of the equipment. Learn how
to stop the mower quickly in an emergency.
Never allow children or people unfamiliar with these instructions to use the mower. Local regulations may
restrict the age of the operator.
Never mow while people, especially children, or pets are nearby.
Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people or
their property.
Do not carry passengers.
All drivers should seek and obtain professional and practical instruction. Such instruction should
emphasise:
The need for care and concentration when working with this machine.
The need to slow down when making tight turning manoeuvres. Failure to take adequate care can affect
stability leading to loss of control of the machine particularly when operating in transport mode.
Control of a ride-on-machine sliding on a slope will not be regained by application of the parking brake.
The main reasons for loss of control are:
- Insufcient wheel grip.
- Being driven too fast.
- Inadequate braking.
- The type of machine is unsuitable for the task.
- Lack of awareness of the effect of ground conditions, especially slopes.
- Incorrect load distribution.
1.8 1.8
SAFETY PRECAUTIONS
Preparation
Check that the machine complies with all applicable regulations, including those in force when used on the
public highway.
While mowing, always wear substantial footwear and long trousers. Do not operate the equipment when
barefoot or wearing open sandals. Eye protection should be worn.
Thoroughly inspect the area where the equipment is to be used and remove all objects which can be thrown
by the machine.
Never operate the machine without rst checking that the operator platform latching mechanism is fully
engaged and in good working order, refer to OPERATOR PLATFORM LATCHING MECHANISM.
Ensure that the cutterheads are fully raised with the latches and safety locks engaged in position before
transporting the mower.
Replace faulty silencers.
Check the condition of the tyres and ensure that they are inated to the correct pressures, refer to
SPECIFICATIONS. This is particularly important if the machine is to be taken on the public highway.
Check that the mower is in good working order, paying particular attention to the brakes and steering. Also
ensure that the forward/reverse speed control pedals move freely to neutral when released.
Before use, always visually inspect to see that the blades, blade bolts and cutting cylinders are not worn or
damaged. Replace worn or damaged components.
Check the mower hydraulic system, particularly the hydraulic hoses, ttings and hose supports. Worn,
crushed or damaged hoses can burst, with risks to health and damage to the machine and surrounding turf
areas.
After refuelling and adding oil to the hydraulic oil tank ensure that the caps are replaced securely.
Check that all linkages, connections and pivot nuts are secure and that wheel nuts are torqued correctly,
refer to SPECIFICATIONS.

SAFETY PRECAUTIONS
Operation
Do not operate the engine in a conned space where dangerous carbon monoxide fumes can collect.
Mow only in daylight or in good articial light.
Before attempting to start the engine, engage the parking brake, disengage the cutterhead drive system and
ensure that the forward/reverse speed controls are in the neutral position.
Never operate the machine without rst checking that the operator platform latching mechanism is fully
engaged and in good working order, refer to OPERATOR PLATFORM LATCHING MECHANISM.
Slopes
Do not use on a slope of more than 16 degrees. Care should be taken when using the mower on any slope
where ground conditions are such that there may be a risk of the mower rolling over. The requirements of
89/355/EEC, as amended by 95/63/EEC ‘Provision and Use of Work Equipment Directive’ should be
considered.
Stability angles given are maximum gures for a machine equipped with a R.O.P.S and are for guidance only.
Particular conditions such as wet grass or uneven ground may not permit safe operation on the slope limits
stated.
Remember there is no such thing as a ‘safe’ slope. Travel on grass slopes requires particular care. To guard
against overturning or loss of traction when travelling or mowing on a slope:
- Exercise extreme care when changing direction on a slope.
- Do not stop or start suddenly.
- Engage drive slowly.
- Keep machine speed low.
- Avoid tight turns.
- Stay alert for humps, hollows and other hidden hazards.
- Keep away from sharp inclines and steep drops.
- A thorough risk assessment should be carried out by a competent person before travelling or mowing on a
slope.
Never park on a slope.

OPERATING THE MOWER
Safety Notice
WARNING: PREVENT ACCIDENTS - Before operating the mower it is essential that;
- The operator reads and understands this manual.
- The operator platform latching mechanism is fully engaged and in good working order, refer to
OPERATOR PLATFORM LATCHING MECHANISM.
- The daily maintenance checks have been properly carried out and the mower is in good working
order.
- The operator should wear safety clothing and eye protection. Failure to do so could result in risk to
health and safety.
- The area where the equipment is to be used is inspected and all objects which may be thrown by the
machine are removed.
Operate safely on slopes;
It is essential to follow safe working practices when working on slopes. In order to avoid potentially
hazardous situations, it is essential that the operator understands and observes the relevant safety
precautions listed in this manual, refer to SAFETY PRECAUTIONS.
This machine is tted with a R.O.P.S as standard to increase operator safety in the event of the
machine rolling over.
The R.O.P.S frame may be folded down to allow access into area of restricted height.
While the R.O.P.S is folded down it does not provide any protection in the event of a roll over and
should not be considered as a Roll Over Protective structure.
Operator Presence Control
Cutting Cylinder Drive Lockout: Drive to the cutting cylinders is only possible when the operator is seated.
If the operator raises off the seat for a period of more than one second, a switch is activated and drive to the
cutting cylinders is automatically disengaged. To re-engage drive to the cutting cylinders, the operator must
return to the seat, then operate the cutterhead drive switch to the ‘OFF’ position before moving it back to the
‘ON’ position. If the operator rises off the seat for a brief moment during normal work, drive to the cutting
cylinders is not affected.
The engine can only be started with the cutterhead drive switch in the ‘OFF’ position.
Engine Start Lockout: The engine can only be started when the forward/reverse travel pedal is in the
‘NEUTRAL’ position, the cutterhead drive switch is in the ‘OFF’ position and the parking brake is engaged.
When these circumstances are satised, switches are activated permitting the engine to be started.
Engine Run Interlock: Once the engine is started the operator must be seated before the parking brake is
released for the engine to continue to run.
Note: The engine will cut out if the operator leaves the seat without engaging the parking brake.

A variable hydraulic weight transfer system is provided for improving tyre grip with the grass surface
- ‘Traction Assistance’.
Hydraulic pressure in the cutterhead lift system
provides a lifting force which reduces cutterhead
weight on the ground and transfers the weight as a
downward force onto the mower’s tyres. This action is known as ‘Weight Transfer’.
To engage weight transfer: The amount of weight
transfer can be varied to suit operating conditions
by rotating the weight transfer hand wheel as follows;
Release the lock wheel underneath the hand wheel

OPERATING THE MOWER
Unblocking Cutting Cylinders Cont’d
NEVER ATTEMPT TO ROTATE THE
CUTTING CYLINDERS BY HAND as there
may be some residual pressure in the hydraulic
system which could cause injury through sudden
movement of the cylinder(s) when the blockage is
released.
Always wear protective gloves and use a suitable
strong wooden instrument. Ensure that this will t
between the blades and through the cylinder and
is long enough to provide sufcient leverage to
release the blockage and any residual hydraulic
system pressure by rotating or rocking the cylinder.
Make sure that the wooden instrument is properly
supported in the cylinder and avoid the use of
excessive force to prevent damage.
Only when the cylinder has a degree of free
movement should the source of the blockage be
removed. Ensure that the wooden instrument is also
removed before restarting the power source.
If the cylinder requires readjustment or repair, refer
to MAINTENANCE - CUTTERHEADS.
Centre Cutterhead Height of Cut
Correction Adjustment
With all cutterheads set at the same HOC via the
indicator rings, it may be noticeable that the centre
unit produces a higher cut nish compared to the
wing units. The centre unit is pulled and the wing
units are pushed this presents marginally different
cutting angles relative to the ground. The amount
of HOC variation, which results from this will be
inuenced by the terrain but satisfactory results can
usually be achieved by setting the centre cutterhead
HOC indicator ring lower than the wing unit
settings.
1.40 1.40
OPERATING THE MOWER
General Operating Hints
1. The rotational speed of the cutting cylinders should always be kept as high as possible in order to
maintain the highest quality of cut. This in turn requires that the engine speed be kept as high as
possible.
2. The quality of cut will deteriorate if the forward speed is excessive. Always balance the quality of cut with the work rate required and set the forward speed accordingly.
3. Never let the engine labour. Reduce the forward speed or increase the height of cut. Check that the
cutting cylinders are not in heavy contact with their bottom blades.
4. Regularly check the cutting cylinder to bottom blade adjustment every few hours even though
cutting performance appears to be satisfactory. Heavy contact or excessive clearances between the cylinder and bottom blades will cause rapid wear to take place.
5. Always disengage the cutterhead drive when travelling across un-grassed areas. Grass will lubricate the cutting edges whilst mowing. Excessive heat will build up if the cutting cylinders are run when not mowing and this will cause rapid wear to take place. For this reason it is also wise to reduce
cutting speed when mowing lightly grassed areas or when the grass is dry.
6. Cutting performance is best when cutting against the lie of the grass. In order to take advantage of this fact, the operator should attempt to alternate the direction of mowing between cuts.
7. Take care not to leave uncut strips of grass at the overlap points between adjacent cutterheads by
avoiding tight turns.
8. It is generally wise to remove rear roller scrapers where conditions allow, as optimum grass dis- charge is achieved without them. Scrapers should be retted when conditions are such that mud and grass start to build up on the rollers. When retting the scraper wires care must be taken to ensure that they are correctly tensioned, refer to MAINTENANCE - EVERY 50 HOURS.
WARNING: PREVENT ACCIDENTS - Take care when travelling over obstacles such as roadside
kerbs. ALWAYS travel at slow speed over obstacles to prevent damage to the machines tyres, wheels
and steering system. Ensure that tyres are inated to the recommended pressures.

OPERATING THE MOWER
Cutterhead General Information
The mower is designed to be used with MK3 200mm (8˝) xed or oating cutterheads or MK3 254mm (10˝)
xed cutterheads.
It is essential that the relationship between the bottom blades and the cutting cylinders are kept in good adjustment and that cutting edges are kept sharp to ensure good cutting performance, minimum power consumption and prolonged life for the cutting edges, refer to MAINTENANCE - CUTTERHEADS.
MK3 Fixed Cutterheads 200mm (8˝) / 254mm
(10˝): When the mower is set up with xed cutter-
heads the height of cut is gauged by the rear roller
and the cutterhead is allowed to pivot laterally to
follow ground contours. This arrangement is normally recommended for general mowing require-
ments.
(MK3 200mm (8˝) Cutterhead illustrated).
MK3 Floating Cutterhead 200mm (8˝): When
the mower is set up with oating cutterheads the
height of cut is gauged by the front and rear rollers.
The cutterhead is allowed to pivot fore and aft as
well as laterally. This arrangement is recommended
for high quality grass areas and performs well
where grass is short and the ground undulations are
severe.
Grass deectors: The rear grass deectors must
always be correctly tted. The deectors should be
set as low as possible to deect grass discharge to
the ground.
WARNING: PREVENT ACCIDENTS - Always
ensure that the grass deectors are angled below
horizontal level, otherwise risks to health and
safety may result.
Height of cut gauge: An optional height of cut
gauge is available to assist in achieving accurate
cut height settings. It is suitable for both xed and
oating cutterheads.

Cutterhead Cylinder To Bottom Blade Adjustment
IMPORTANT: PREVENT DAMAGE - It is essential that the relationship between the bottom blades
and the cutting cylinders is kept in good adjustment in order to ensure good cutting performance,
minimum power consumption and prolonged life for the cutting edges.
Carry out the following procedure before commencing work and
re-check the settings every few hours.
Check that the cutting cylinder is correctly set to the bottom blade
by holding a thin piece of paper between the cutting cylinder and the
bottom blade as shown. Carefully rotate the cylinder as shown and
check that the paper is cut cleanly at all points along the length of the
blade. Hold the paper at 90 (right angles) to the bottom blade to
obtain the correct cutting action.
WARNING: PREVENT ACCIDENTS - Ensure that people are clear of the cutting cylinders as rotation
of one may cause others to rotate.
If adjustment is necessary proceed as follows;
Release nut ‘A’ 1/4 turn both ends.
Turn hand wheel ‘B’ each end alternately whilst rotating the cutting
cylinder backwards until the bottom blade is in ‘eeting’ contact with
the cylinder along its entire length. Re-check the cutting action along
the length of the bottom blade using a thin piece of paper making
marginal adjustments as necessary.
Tighten nut ‘A’ both ends.
If it is impossible to obtain a good clean paper cut across the entire length of the bottom blade it will be necessary to carry out the back lapping procedure to reprocess the cutting edges. In severe cases it will be necessary to regrind the cutting cylinder and the bottom blade, refer to BACK LAPPING/GRINDING.
Do not be tempted to over adjust, thus causing heavy contact between the cylinder and bottom blade, as this
will cause very rapid uneven wear to take place leading to tram lining and waviness of the cutting edges. The
frictional losses will be high and a signicant amount of power will be absorbed, thus reducing the power
available for cutting. The heating effect due to friction will cause excessive expansion to take place which
will further aggravate the situation by increasing the contact pressure.
If the cutterheads are allowed to operate for more than a few hours without adjustment the running wear will
eventually cause the cylinder to run out of contact with the bottom blade. At this stage very rapid rounding of
the cutting edges will occur as grass and abrasive particles pass through the clearance between the blades.
Lack of attention to adjustment can therefore be foolhardy as maintenance costs will escalate. The quality of
cut will also be seriously affected as will the health and growth of the grass.
An experienced operator will notice when a cutterhead starts to go out of adjustment; when the grass ceases
to be cut cleanly and the cut ends become ragged.

MAINTENANCE
Cutterhead Back Lapping
This process is recommended for restoring the
sharp cutting edges to cylinders and bottom blades
which are essential for good quality grass cutting.
This process can only deal with a small amount of
metal removal to restore the cutting edges. If the
blade edges are seriously worn or damaged it will
be necessary to remove the component parts and
have them reground.
The back lapping process:
1. Check that the mower engine is switched off
and the parking brake applied.
2. Adjust the cutting cylinders to the bottom
blades to obtain ‘eeting contact’.
3. Apply a medium grade detergent based
carborundum paste to the cutting edges
of the cylinders with a long handled brush.
80 Grade Carborundum paste
Part No.
0.45 kg (1 lb)63-07-088
11.25 kg (25 lb)63-07-086
4. Ensure that the area surrounding the
cutterheads is clear of people and keep hands
and feet clear of the cutting cylinders during
the period when the mower engine is running.
5. Sit on the operator seat, start the mower
engine and set the engine speed at idle.
6. Operate the cutterhead drive switch to the
‘reverse/back lap’ position for a period of time
and listen to the grinding action .
7. Operate the cutterhead drive switch to the ‘off’
position and switch off the mower engine when
the grinding action has stopped.
8. Thoroughly clean the blade edges and adjust
the cutting cylinders to the bottom blades.
Check that a thin piece of paper can be cut
cleanly at all points along the cutting edges
while rotating the cylinders by hand.
9. If further back lapping is necessary repeat steps
2 to 8.
10. Thoroughly remove and wash off all traces of
the carborundum paste from the cylinders and
bottom blades.
1.58 1.58
MAINTENANCE
Cutterhead Grinding
It will be necessary to carry out a grinding operation to correct cylinder spiral edges or bottom blade edges
which have become excessively rounded or distorted. Bottom blades which are nearing the end of their wear
life should be replaced. The new blades should be ground on their holders prior to tting, refer to
CUTTERHEAD BOTTOM BLADE REPLACEMENT. When grinding operations are necessary it is
essential that both cylinders and bottom blades are ground at the same time. The only exception to this rule is
when a new cylinder is tted in which case it is only necessary to grind the bottom blade. All such
grinding operations should be carried out by your authorised dealer on a quality, well maintained cylinder/
bottom blade grinding machine.
Cutterhead Bottom Blade Replacement
Remove the bottom blade holder by removing the three xing bolts at each end and withdraw from the
cutterhead. Remove the worn bottom blade and discard the countersunk screws and securing nuts. Fit the new
blade to the holder and loosely assemble with new countersunk screws and securing nuts. Tighten the centre
bolts to a torque of 40Nm (30 lbf.ft). Continue by tightening the remaining bolts to the same torque by
working from the centre out towards the blade ends.
The new bottom blade must be ground on its holder prior to retting to the cutterhead.
Adjust the cutting cylinder position to give adequate clearance for tting the new bottom blade holder. Ret
the bottom blade holder assembly to the cutterhead using the original xing bolts and tighten to a torque of
35Nm (26 lbf.ft). Finally adjust the cylinder to the bottom blade, refer to CUTTERHEAD CYLINDER TO
BOTTOM BLADE ADJUSTMENT.
