NOTE TO CUSTOMER / OWNER

Please ensure that the above section above has been completed and signed by the selling
dealer to verify that your machine has been registered with Twose of Tiverton Limited.

IMPORTANT: During the initial ‘bedding in’ period of a new machine it is the customer’s responsibility
to regularly inspect all nuts, bolts and hose connections for tightness and re-tighten if required. New
hydraulic connections occasionally weep small amounts of oil as the seals and joints settle in – where
this occurs it can be cured by re-tightening the connection – refer to torque settings chart below. The
tasks stated above should be performed on an hourly basis during the first day of work and at least
daily thereafter as part of the machines general maintenance procedure.

Attachment to Tractor

Select a firm level site on which to attach the
mower to the tractor.

Reverse tractor up to machine positioning
linkage arms (1) at a suitable height for
attachment, secure in position with locking pins
(2).

Fit top link (3) and secure with link pin and
locking pin (4).

Ensure linkage lift rods on both sides are set at
the same height and secured.

Note: The top link should be adjusted to an angle of

at least 3° greater than the lower links arms – refer

to diagram below.

Raise support leg (5) into the stowed position
and secure in place with its lock pin (6). Do not
remove the support leg.

Setting of Side Position

The working position of the machine (side position) is set by sideways adjustment of the
lower link arms to a point where the cutting area of the machines is just beyond the tractor

wheel on its working side – see illustrations below.

Shift the mower sideways on the lower link arms (2) to achieve the required distance (A),
secure in position with stabiliser arms (3). Additional shift (±

100mm) is available by altering

the position of the lower linkage pins.

OPTICUT 220/260/300
Rotary Disc Mowers

Vertical Adjustment (Side to Side)

Ensure the frame of the machine is
vertical as shown opposite ►

◄ If required, adjust the lower links (1) and lift rods

(2) to bring the frame into the vertical (side to side)

position.

Vertical Adjustment (Front to Back)

The correct vertical position of the frame, front to back, is with the frame tilted forward by 2°
in the direction of travel, this can be gauged by viewing the protection curtain (1); all the
lower edges should be equidistant to the ground when the machine is set correctly.

Rotate the adjuster nut (3) on top link (2) to achieve this setting – refer to illustrations below.

Note: This 2° inclination of the machine will produce a grass cut height of 50 – 55mm. The
tilt angle may be adjusted to suit individual preference but under no circumstances should it
exceed 7°.

The support leg is designed so the machine is automatically leaned forward by 2° when the
machine is disconnected.

OPTICUT 220/260/300

Rotary Disc Mowers

Adjusting Frame Work Height

Place the machine into the working position; the optimal working position is when the base
end of the support arm (1) is located midway within its guide slot – an indicator ‘notch’ (2)
marks this position. Raise or lower the machine on the tractors three-point linkage to
achieve this central position. Secure the linkage in position when the working height has
been set.

Note: This machine has the ability to work with the cutterbar at angles of between -30° and
+45°; when working at these angles the cutterbar should be brought back into the parallel
position every 15 minutes or so and run for 4 minutes to ensure continuous lubrication.

PTO Shaft Fitment

On initial fitment the PTO shaft halves (1 & 2) will need to be measured and cut to suit the

particular application – refer to following page for details.

Install PTO shaft (3) and fit torque chains to PTO guard (4) at each end of the shaft to
prevent them from rotating with the shaft.
Check the PTO shaft does not foul on the tractor or machine during normal operation and
manoeuvring; failure to observe this can result in damage to components.

OPTICUT 220/260/300
Rotary Disc Mowers

10

PTO Driveshaft

The PTO driveshaft attaches between the tractor and the machine gearbox to transfer the
power required to the run and operate the machine – it is important to achieve the correct
shaft length to avoid risk of it ‘bottoming out’ when raising or lowering the machine.
The procedure for measuring and cutting the shaft is as follows:

Measuring the PTO Shaft

With the machine attached to the
tractor in the working position measure
the horizontal distance ‘A’ from the
tractor’s PTO to the input shaft on the
machines gearbox and subtract 75mm

(3”) – this figure is the required shaft
length.

Place the fully closed PTO shaft on the
ground and measure its overall length,
if the shaft is shorter than the required
length you can use it without the need

to shorten - providing it allows for a

minimum 150mm (6”) overlap when
fitted.

If the shaft is longer subtract the
required shaft length plus an additional

75mm (3”) - the resulting figure is the

excess length that will need to be
removed from each half of the shaft.

Cutting the PTO Shaft

Separate the two halves and using the
measurement obtained above shorten
both the plastic guarding and the inner
steel profile tubes of each shaft by this

same amount. De-burr the cut tubes

with a file to remove rough or sharp
edges and thoroughly clean to remove
swarf before greasing, assembling and
fitting the shaft.

Always secure the PTO guards with torque chains to prevent them from rotating with the
shaft. Check to ensure the shaft does not contact or foul tractor or machine components
during normal operation - failure to observe this can result in damage to the tractor and/or
machine.

NOTE: For subsequent use with different tractors the shaft should be measured again to

check suitability – there must be a minimum shaft overlap of 150mm (6”).

Maintenance

To increase the working life of the PTO shaft it should be periodically checked, cleaned and

lubricated – refer to the PTO maintenance section for further details on this subject.

OPTICUT 220/260/300

Rotary Disc Mowers

11

Hydraulic Connection

The machine requires one hydraulic
connection; this is for operation of the
hydraulic ram that raises and lowers the
cutterbar.

The minimum working pressure necessary to
operate the machine is 50bar and a maximum
of 200bar.

Before connecting the hydraulic hose (1) to the tractor ensure that the control for that
service is in the midpoint ‘off’ position and the system is not pressurised.

NOTE: Ensure all hydraulic connections are kept free from dirt and other contaminates that
can cause damage to a hydraulic system.

Transport Locking Mechanism

Route the operation cord (1) for the transport locking
mechanism (2) into the tractor cab through the rear
window – ensure sufficient slack is retained in the cord
run to avoid accidental operation of the mechanism.

Fix the cord to a suitable location in the cab that is easily
accessible to the operator.

WARNING!
The transport latch operation cord must be slack at all
times to avoid unintentional operation of the latch. Ensure
the cord is kept clear of any components on the tractor
and the machine that may cause accidental tightening of
the cord and operation of the latch.

Ballast

Add front end weights to the tractor if required to increase stability of the unit for both
transportation and work. Refer to tractor manufacturer’s handbook for advice on ballasting.

OPTICUT 220/260/300

Post Attachment Checks

After attaching the machine the following checks should be performed, ensure the tractor is
switched off and the starting key removed.

Check the attachment of the machine to the tractor;

 Operating height of the hitch.

 Hitch installation.

 Frame angle (2° inclination in the direction of travel).

Check position of the support leg.

Check all guarding is correctly located and undamaged.

Check lubrication levels in all drives.

Check all vital parts are present and working correctly.

Check parts for wear, damage or looseness on used machines, particularly;

 Blades.

 Discs.

 Quick change blades.

 Belts.

 Guards.

 Protection curtain.

In the event of damage or excessive wear to vital parts of the machine, replacements
must be sourced and fitted before attempting to operate it. Each disc on the machine is
fitted with 2 blades; these must be new or evenly worn. For safety and long working life
always replace components with genuine parts from the manufacturer.

With all persons are kept at a safe distance from the machine, conduct a test run with the
machine running at 540RPM.

 In the event of excessive noise and/or vibration, stop the machine and correct the

problem.

 If the problem continues, contact authorised service centre for advice or help.

If all the above criteria are met the machine is ready for operation.

Spring Assisted Weight Distribution

To aid weight distribution and reduce mechanical stress the machine is fitted with 2 spring
dampeners; the smaller spring supports the heel of the cutterbar and the larger spring
supports the whole cutterbar. These are adjustable to suit operating preference and specific
working conditions.

Factory setting for the spring is: Distance ‘X’ = 70mm

Spring Adjustments

To reduce spring tension on the cutterbar, reduce distance ‘X’ on small spring (1) and
relocate pin (2) on the large spring to the previous hole position, to increase tension,
increase distance ‘X’ and move pin (2) to the next hole.
NOTE: Adjustment to the larger spring must be performed with the machine folded into the
transport position.

▲
Ensure ram tap is closed for transportation.

Moving Into Transport Position

For transportation of the machine the cutterbar must be raised into the vertical position; the
procedure for moving into transport is as follows:

 With the machine in the horizontal work position, fold the

outer end of the protection curtain (1) over the top of the
cutterbar.

 Pull and retain tension on the operation cord (2) to

disengage the transport locking mechanism.

 Operate the hydraulic ram to raise the cutterbar.

Tension on the operation cord can be released once the
cutterbar has reached an angle in excess of 60°.

 Continue operation of the ram until the cutterbar is

upright at 90° and the transport lock has fully engaged.

 Close tap (4) on the ram valve.

The machine is now folded and ready for transportation.

WARNING! Always be aware of the height of the machine during transport and take extra care when

manoeuvring close to buildings and under low bridges.

OPTICUT 220/260/300

Rotary Disc Mowers

15

Moving from Transport into Work Position

The procedure for moving from transport to work position is basically a reversal of moving
from work into transport.

 Open tap on ram valve.

 Pull and retain tension on the operation cord to disengage the transport locking

mechanism.

 Operate the hydraulic ram to lower the cutterbar.

Tension on the operation cord can be released once the cutterbar reaches an angle of
approximately 80°.

 Continue operation of the ram until the cutter has reached its horizontal work position

and the latch has re-engaged.

 Re-position the protection curtain.

The machine is now ready for work.

Raising and Lowering the Cutterbar in Work

Raising and lowering the cutterbar when moving between rows or turning on the headland
is performed by operation of the hydraulic ram. Do not pull the cord for the transport latch.

Raising the cutterbar during work is by operating the ram with the transport latch engaged.

CAUTION!
When raising the cutterbar with the machine running there is risk of danger from flying
objects such as stones or other hard objects; ensure persons and animals are clear of the
danger zone before raising the cutterbar when the machine is running. Always cease
working and stop the machine when persons approach, do not re-start until they are clear of
the danger zone.

Instructions for Safe Mowing

 Always ensure that each disc is fitted with 2 knives, either new or equally worn.

 Always replace damaged or worn blades, knives, and knife holders immediately – never

attempt to operate the machine with any of these components in a damaged or overly
worn condition.

 Stop the machine immediately if an increase in noise or vibration is experienced –

continue work only when the reason for the disturbance has been investigated and

resolved. Ensure both the machine and the tractor’s engines are switched off before

nearing the mower to investigate.

 Only operate the machine at the correct PTO speed.

Mowing Instructions

 Allow the mower to reach its maximum permitted PTO speed before entering it into the

grass to cut and keep the machine at this speed for the duration of the mowing to
