SAFETY 3

3.1 HOW TO OPERATE SAFELY _____________________________________________

3.1.1 Safe operation

a) Read the instructions carefully. Know the

controls and the correct use of the

equipment;

b) Children or persons who do not understand

these instructions must not use the

machine. The Local regulations will set the

age of the operator;

c) Never use a machine near persons,

including children or animals;

d) Remember that the operator or user is

responsible for accidents or hazards that

occur to other persons or their property.

e) Do not carry passengers;

f) All drivers must get instruction. That

instruction must include:

- A need for careful attention when you use a

“ride-on” class machine.

- The loss of traction on slopes or in a

condition of decreased traction, is not

always corrected by an application of the

brakes.

Reasons for the loss of control.

i) Not enough wheel grip;

ii) Driving at more than the safe speed for the

conditions

iii) You over brake or brake suddenly.

iv) The type of machine is wrong for the job;

v) No attention given to the ground conditions

or operating slopes;

vi) Incorrect hitch and load distribution.

3.1.2 Preparation

a) When you operate the machine, always

wear strong footwear and long trousers. Do

not operate the equipment without the

correct footwear.

b) Inspect the area you are to cut. Objects or

any particles in the area are a safety risk.

Remove these objects. These objects can

damage the blades or cause injury to any

person near.

c) WARNING - Diesel and Petrol are

flammable.

- Store in clean applicable metal containers.

- Refuel outdoors only and do not smoke

when you add fuel;

3 SAFETY

e) Remember there is no safe slope. Operate

with caution on grass slopes.

To guard against a turn over

- Do not stop or start suddenly when you

operate on a slope.

- To operate on a down slope, prevent sharp

movements on the controls and always

keep the machine in gear.

- Go slowly when you operate on slopes and

when you make tight turns;

- Look for any changes in the cutting surface

that can change the mowers balance.

- Never use the mower to move across a

slope on a diagonal line. Unless the

machine is for this purpose;

f) When you pull a load or use accessories,

be careful.

- Use only approved drawbars;

- Any load must not change your full control

of the machine.

- Do not turn suddenly. Be careful when you

move in a reverse direction;

- Use the counterweight or wheel weights

recommended in the instruction handbook;

g) Be careful of those around you and the

users of the road when you move across or

near roadways;

7 OPERATION

7.2 OPERATING PROCEDURE ______________________________________________

1. Do not operate with loose, damaged or missing components. Whenever possible mow when grass is

dry

2. First mow in a test area to become thoroughly familiar with the operation of the controls.

3. Study the area to determine the best and safest operating procedure. Consider the height of the grass,

type of terrain, and condition of the surface. Each condition will require certain adjustments or

precautions.

4. Never direct discharge of material toward bystanders, nor allow anyone near the machine while in

operation. The owner/operator is responsible for injuries inflicted to bystanders and/or damage to their

property.

5. Use discretion when mowing near gravel areas (roadway, parking areas, cart paths, etc.). Stones

discharged from the implement may cause serious injuries to bystanders and/or damage the

equipment.

6. Disengage the cutter motors and raise the implements when crossing paths or roads. Look out for

traffic.

7. Stop and inspect the equipment for damage immediately after striking an obstruction or if the machine

begins to vibrate abnormally. Have the equipment repaired before resuming operation.

10. Do not operate with loose, damaged or missing components.

CAUTION

To Help Prevent Injury, Always Wear

Safety Glasses, Leather Work Shoes Or

Boots, A Hard Hat And Ear Protection.

CAUTION

Remove All Debris From The Site Before

Mowing. Enter A New Area Cautiously

Always Operate At Speeds That Allow

You To Have Complete Control Of The

Mower.

CAUTION

Before You Clean, Adjust, Or Repair

This Equipment, Always Disengage All

Drives, Lower Implements To The

Ground, Engage Tractor Parking Brake,

Stop Engine And Remove Key From

Ignition Switch To Prevent Injuries.

en-19

OPERATION 7

7.3 ATTACHING THE MOWER TO THE TRACTOR P.T.O. SHAFT __________________

A standard P.T.O. shaft is provided and this will have to be

shortened in length to suit the tractor being used. It is

essential that no more than is necessary is cut off as

maximum engagement of the sliding portion is needed to

prevent excessive wear.

Adequate removal of sharp edges and chamfering of the

cut ends must be carried out.

1. Stop the tractor engine.

2. Connect the tractor lower lift arms to the 2-hitch

points (A) on the main crossbeam, using the

lower hole in the hitch plates to fit the

connecting pins and spring clips.

Connect the tractor top link (B) to the machine.

3. Fit pin (B) and secure with pin and spring ring.

4. Extend the top link and remove the stabiliser pin

from the rear of the unit pivot support plates.

Stow this pin in the holes in the lugs at the front

of the main crossbeam and secure with spring

pins.

5. Shorten the top link until the 'A' frame becomes

vertical. Attach the jubilee clip (supplied) to the top link up against the end of the turn buckle and

tighten securely in this position.

6. Connect up P.T.O. shaft (C) to the machine and tractor.Connect lift hose QRC to Tractor QRC.

NOTE

On certain tractors it will be impossible to lift the machine to the maximum height on the three point linkage

without the sliding part of the P.T.O. shaft disengaging. Stops must be set correctly on the tractor lift quadrant to

limit the lift height to prevent the disengagement of the P.T.O. shaft.

IMPORTANT

Select the pair of holes in the 'A' frame which

allows the top link to take up as near a horizontal

position as possible.

en-20

7 OPERATION

7. Start the tractor engine and lift the machine fully by means of the tractor lifting quadrant lever.

8. Switch off the engine.

9. Adjust the tractor RH lift rod length to level the main crossbeam of the machine.

10. Measure the height of the crossbeam from the ground at each end to ensure the machine is level.

11. Adjust the length of the check chains so that there is a minimum of slack when the tractor arms are

fully raised. This will prevent excessive side swing of the machine when transporting.

Before this adjustment can be made, the height of cut of all three units must be set accurately with the machine

on a level, hard surface (see page 23). The ‘A’ frame must be vertical.

On the area to be cut, make an initial cut of approximately 20 metres. Examine the finish of cut across the width

of the swathe - it is likely that the 2-front units will be cutting lower than the rear unit. If necessary, to obtain an

even cut, extend the top link by 1½ to 2 turns.

Any subsequent changes in height of cut will not effect the length of the top link; but it is important that is the units

are set up by using spacers between the ground and bottom blade, the top link should be shortened to its original

length, ie. until the turnbuckle contacts the jubilee clip. After resetting the height of cut by this method, the top link

should again be lengthened by the same amount.

NOTE

If external tractor check chains are fitted, they should be adjusted so that no part of the lift arms can foul

against the hydraulic pump or any of the fittings when the machine is in the cutting position. This will prevent

excessive side swing of the machine when transporting.

IMPORTANT

Do not lengthen the top link by more than 3 turns; the need for adjustment in excess of this indicates that the

height of cut settings on the units were not equal initially.

NOTE

Alternatively, the height of cut setting on the individual units can of course be adjusted slightly to obtain an even

finish without altering the length of the top link.
