SAFETY PRECAUTIONS

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 brake.

The main reasons for loss of control are:

- Insufficient 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.

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 first checking that the operator platform latching mechanism is fully

engaged and in good working order, refer - ‘OPERATOR PLATFORM LATCHING MECHANISM’.

READ THIS MANUAL BEFORE USING THE LT324 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.

1.6 1.6

924916KG251004

SAFETY PRECAUTIONS

PREPARATION Continued.

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 inflated to the correct pressures, refer -

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, fittings 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 - SPECIFICATIONS.

Before operating the machine ensure that there are no foreign objects or liquids on the platform or ped-

als - ALWAYS KEEP THE OPERATOR PLATFORM CLEAN/CLEAR.

OPERATION

Do not operate the engine in a confined space where dangerous carbon monoxide fumes can collect.

Mow only in daylight or in good artificial 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 first checking that the operator platform latching mechanism is fully

engaged and in good working order, refer - OPERATOR PLATFORM LATCHING MECHANISM.

Stored energy devices are charged when the outer wing units are in transport position. Always operate

the relevant lift controls to provide hydraulic support for the wing units suspensions before attempting

to release the transport latches.

1.7 1.7

924916KG251004

SAFETY PRECAUTIONS

OPERATION Continued.

Do not use on a slope of more than 19 degrees. Where ground conditions are such that there may be a

risk of the mower rolling over, the requirements of SI 1998 No 2306 "Provision and Use of Work

Equipment Regulations" should be considered, refer - INTRODUCTION - Optional Extras.

Ground conditions affect traction. Particular conditions may not permit safe operation on the slope lim-

its 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

OPERATOR PRESENCE CONTROLS

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 released

to the 'NEUTRAL' position, the cutterhead drive switch is in the ‘OFF’ position and the parking brake is

engaged. When these circumstances are satisfied, switches are activated permitting the engine to be start-

ed.

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.

With the engine running and the machine moving with the travel pedal depressed, the engine will contin-

ue to run when the operator rises from the seat. If the travel pedal is then allowed to return to neutral the

engine will cut out.

WARNING: PREVENT ACCIDENTS - Do not operate the turf mower if the operator presence

controls are defective in any way. ALWAYS replace faulty parts and check that they function

correctly before operating the mower.

SAFETY NOTICE

OPERATING THE MOWER

BRAKING SYSTEM

Parking brake : Move the parking brake lever to its rear position to engage the

parking brake. Do not operate the mower with the parking brake engaged.

WARNING : PREVENT ACCIDENTS - The parking brake operates on the front wheels only. Do not

park the mower on a slope.

Service brakes : Service braking is achieved by the hydraulic transmission system. When the forward or

reverse travel pedals are released or the engine speed reduced, service braking becomes effective and trav-

el speed is automatically reduced. To increase the braking effect, push the transmission pedal into the neu-

tral position. Service braking is effective on the front wheels only.

WARNING : PREVENT ACCIDENTS - The service braking system will not hold the mower at a stand-

still. ALWAYS ensure the parking brake is engaged to park the mower at a standstill.

Emergency braking : In the event of service brake failure, turn the ignition off to bring the mower to a

standstill.

WARNING: PREVENT ACCIDENTS - Take care when operating the emergency braking system.

Remain seated and hold on to the steering wheel to prevent ejection from the mower caused by the

front wheel brakes being applied suddenly when travelling.

THROTTLE CONTROL

Operate the throttle control in a forward direction to increase the engine speed.

Operate the throttle control in a rearward direction to reduce engine speed.

Note that the engine speed dictates the speed of the other functions, i.e. travel, cut-

ting cylinder, position controls.

TRAVEL

Forward travel: Depress the forward travel pedal to increase forward travel

speed. Release the pedal to reduce speed.

Reverse travel: Depress the reverse travel pedal to increase reverse travel speed.

WEIGHT TRANSFER / TRACTION ASSISTANCE

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 1/2 turn anti-clockwise and hold.

Rotate the hand wheel: - Anti-clockwise to reduce weight transfer.

- Clockwise to increase weight transfer.

Tighten the lock wheel.

GENERAL OPERATING HINTS

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.

The quality of cut will deteriorate if the forward speed is excessive. Always balance the quality of cut

with the workrate required and set the forward speed accordingly.

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.

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.

Always disengage the cutterhead drive when travelling across ungrassed 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.

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.

Take care not to leave uncut strips of grass at the overlap points between adjacent cutterheads by

avoiding tight turns.

It is generally wise to remove rear roller scrapers where conditions allow, as optimum grass discharge is

achieved without them. Scrapers should be refitted when conditions are such that mud and grass start to

build up on the rollers. When refitting the scraper wires care must be taken to ensure that they are cor-

rectly tensioned, refer - 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 inflated to the recommended pressures.

OPERATING THE MOWER

CUTTERHEAD GENERAL INFORMATION

The mower is designed to be used with MK3 200mm fixed or floating cutterheads or MK3 254mm

fixed 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 - MAINTENANCE - Cutterheads.

Fixed MK3 200mm/254mm Cutterheads: When the mower

is set up with fixed cutterheads 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 requirements.

(MK3 200mm Cutterhead illustrated).

Floating MK3 200mm Cutterheads: When the mower is set

up with floating 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 deflectors: The rear grass deflectors must always be

correctly fitted. The deflectors should be set as low as possible

to deflect grass discharge to the ground.

WARNING: PREVENT ACCIDENTS - Always ensure

that the grass deflectors 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 fixed and floating cutterheads. Hayter Part No. 63-01-760

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 pro-

duces a higher cut finish 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 influenced by the terrain but satisfactory results can usually be achieved by setting the

centre cutterhead HOC indicator ring lower than the wing unit settings.

WARNING : PREVENT ACCIDENTS - When carrying out maintenance procedures it is essential that:

- The engine is switched off and the ignition key removed.

- The parking brake is applied.

- There is no pressure in the hydraulic system.

- The cutterheads are fully down on the ground.

- The safety precautions in this manual have been read and understood.

IMPORTANT: PREVENT DAMAGE: Regular maintenance is essential for the continued safe

operation of the machine. Correct servicing will prolong the working life of the machine and

safeguard the "Hayter Warranty". Always fit genuine 'Hayter service parts' as these are

accurately matched to the required duty.

Dirt and contamination are the enemies of any hydraulic system. When carrying out maintenance

procedures on the hydraulic system always ensure that the work area and the components are

thoroughly clean before, during and after refitting. Ensure that all open hydraulic lines and ports, etc. are

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 degrees (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 handwheel 'B' each end alternately whilst rotating the cutting

cylinder backwards until the bottom blade is in 'fleeting' 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 backlapping procedure to reprocess the cutting edges. In severe cases it

will be necessary to regrind the cutting cylinder and the bottom blade, refer - BACKLAPPING /

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 tramlining and waviness of the cut-

ting edges. The frictional losses will be high and a significant amount of power will be absorbed, thus

reducing the power available for cutting. The heating effect due to friction will cause excessive expan-

sion 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 qual-

ity 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.

CUTTERHEAD BACKLAPPING

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 backlapping process:

Check that the mower engine is switched off and the parking brake applied.

Adjust the cutting cylinders to the bottom blades to obtain ‘fleeting contact’.

Apply a medium grade detergent based carborundum paste to the cutting

edges of the cylinders with a long handled brush.

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.

Sit on the operator seat, start the mower engine and set the engine speed at

idle.

Operate the cutterhead drive switch to the 'reverse/backlap' position for a

period of time and listen to the grinding action .

Operate the cutterhead drive switch to the 'off' position and switch off the

mower engine when the grinding action has stopped.

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.

If further backlapping is necessary repeat steps 2 to 8.

Thoroughly remove and wash off all traces of the carborundum paste from

the cylinders and bottom blades.

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 fitting,

refer - 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 fitted in which case it is only necessary to grind the bottom blade.

All such grinding operations should be carried out by your dealer on a quality, well maintained

cylinder/ bottom blade grinding machine.

CUTTERHEAD BOTTOM BLADE REPLACEMENT

Remove the bottom blade holder by removing the three fixing 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 40 Nm. 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 refitting to the cutterhead.

Adjust the cutting cylinder position to give adequate clearance for fitting the new bottom blade holder.

Refit the bottom blade holder assembly to the cutterhead using the original fixing bolts and tighten to

a torque of 35 Nm. Finally adjust the cylinder to the bottom blade, refer - CUTTERHEAD CYLINDER
