Machine Description
Manufactured with a 17” (43cm) 20” (51cm) or 24” (61cm) cutting width this mower is powered by a 5.5 h.p. air cooled
single cylinder four stroke petrol engine (3.5hp FT430) The rear roller is powered via a slipping brake band clutch
mechanism that allows innite speed control independent of the cutter unit. The drive to the roller is engaged by a lever
situated on the right handlebar.
Where possible, steps have been taken during the design of this machinery to reduce noise emission***.
To take full advantage of this, it is essential that the machine only be used when setup correctly and is fully serviceable
(see instructions).
*** including tment of low noise variant Honda engine.
In the design of the machine, special attention has been given to the importance of easy service and maintenance with
the construction based on a sectional assembly system. These are the Engine Unit, the Cassette Unit, the Rear Roller
Unit, and the Front Roller Unit, each of which can be readily removed individually from the main Frame Chassis Unit.
The interchangeable cassette system allows a variety of cassettes to be used for varying applications.

BEFORE YOU OPERATE THIS MACHINE YOU MUST READ AND STUDY THIS MANUAL.
IF YOU ARE IN ANY DOUBT PLEASE ASK YOUR EMPLOYER OR CONTACT US DIRECT.
CAUTION
IMPORTANT INFORMATION PLEASE READ ALL THE DETAILS IN THIS SECTION AND
FAMILIARIZE YOURSELF AND ALL MACHINE OPERATORS WITH THE CONTENTS.
CAUTION
GENERAL
A centrifugal clutch is tted in the primary drive system. When the engine revs are at
tickover the clutch disengages and neither the cutter nor the rear roller controls will
function. Under these conditions the Deadmans Control can be released and the engine
will continue to tick over.
On increasing the revs of the engine with the throttle control the clutch engages thus
allowing cutter and roller to operate.
TO ASSIST THE SLOWING OF THE BLACK CENTRIFUGAL CLUTCH DRUM APPLY THE
BRAKE BAND LEVER.
NOTE
THE DEADMANS LEVER MUST BE DEPRESSED WHEN
INCREASING THE ENGINE REVS OR THE MACHINE
WILL STOP
NOTE
The drive to the cutter unit can be engaged or disengaged in one of two ways:-
A) By reducing the engine revs to tickover the centrifugal clutch will disengage. This method will be performed when
emptying the grassbox.
b) By having the dog drive disengaged. Use this method when transporting the machine.
When the centrifugal clutch is engaged the rear roller drive can be activated by the brake band lever.
TRANSPORT (Disengaging the Cassette Drive)
To ensure the safety of operator and machine we strongly recommend disengaging the
cassette drive when transporting under power between sites. Do not operate any
cassettes with dog drive disengaged except for the sorrel roller, ironing roller and slitter.
This is achieved by performing the following procedure:
1) Reduce engine revs to tickover. This will cause the black clutch drum to cease rotating.
2) Lift the red ball knob (attached to horizontal rod behind engine) and push towards the
machine. Locate the rod between the two nuts in the slotted catch plate.
3) Once in position the dog drive is disengaged.
To re-engage the dog clutch:
1) Reduce engine revs to tickover as above (1).
2) Lift control rod clear of the locating slot and allow it to spring back towards you.
3) Slowly increase engine revs until an audible click is heard when the dogs engage. Alternatively rotate the black clutch
drum about half a turn by hand and the same click will be heard. Do not rev the engine until the rod has moved right
across and fully engaged.

FT & Super Six SP20001_REV_6
STARTING THE ENGINE
Once the preparatory steps have been completed as outlined on page 7 the engine may be started. (See manufacturer
operating manual for full details).
1) Switch on the fuel tap.
2) Switch the handlebar cut off switch to ON, or depress deadmans handle (Item 1)
3) Set the throttle control to a half open position.
3) Shift the choke lever to the appropriate position (Kubota engine set to START : Honda engine set to the CLOSE
position). The choke is not required if the engine is warm or the air temperature high.
4) Grasp the recoil start handle until resistance is felt, then pull it with force.
5) Do not allow the starter grip to snap back against the engine. Return it gently to prevent damage to the starter.
6) Once the engine is started gradually ‘open’ the choke lever (move the lever towards the RUNNING, or OPEN
position). Warm-up running of 3-5 minutes is recommended.
STOPPING THE ENGINE
1) Set the throttle control to the CLOSED position.
2) Switch the handlebar cut off to OFF or switch off at engine.
3) Close the fuel tap.
TO COMMENCE MOWING
With the starting preparations completed and all of the adjustments from the ‘General
Adjustments’ section made, the machine can be put into motion.
Firstly ensure the dog clutch is engaged. Open the throttle control on the left handlebar
which will engage the inertia clutch and spin the cassette reel. The engine speed
controls the rotational velocity of the cassette. Set the throttle to an approximately half
open position.
To engage the rear roller drive, gently raise the driving clutch lever on the right handle
bar (Item 2). The amount of depression on the lever dictates the speed of travel giving
the operator total control over the speed and handling of the mower.
When the handle is released the machine will stop. To stop the unit head rotating, reduce the throttle to tick over and this
will disengage the inertia clutch.

As an indication coins measure the following:-
- 1p 1.58mm (0.063” ) - 2p 1.80mm (0.071” ) - 5p 1.73mm (0.067” )
- 10p 1.84mm (0.072” ) - 50p 1.84mm (0.072” ) - £1.00 3.14mm (0.124” )
Remember height of cut is effected by moisture of turf , weight of machine and the
thatch density. Different makes of machine cut at different heights when set to the
same position with the setting bar. We suggest you set it to a couple of mm above your
planned height and then come down in height by trial.
If on setting the height of operation you nd it needs altering once on the green simply
click the adjusters up or down the same on each side until the desired height of
operation is achieved.
Always check height of cut/operation with the setting bar provided. Check in two
positions i.e. one at either end of the cassette. Failure to do this could result in an
uneven cut.
Operating Instructions
General Adjustments
SETTING FOR HEIGHT OF CUT
Always stop the engine before adjusting the height of cut. Failure
to do this may result in severe injury.
The length of grass after cutting, or depth of scarication /
dethatching / brushing, depends on the setting of the front roller in
relation to the main frame of the machine.
FT
The Click system allows easy adjustment of the front roller postion
each click representing a change of 0.5mm (0.020”). The roller is
set to be equal on leaving the factory so when the arrows point forward on both decals the roller is level.
SUPER SIX
Adjustment to the height of the front roller is on the quadrant brackets at each end of the roller outisde the main frame
assembly. Undo the adjuster knob on each side of the mower and move the roller up or down and then re-tighten the
knobs. There are notches in the quadrant plates which must correspond with the hole in the side plate on both sides of
the mower to ensure the roller is level.
Check it is level using the setting bar between the front and rear roller with the underside of the screw ledging on the
bottom blade.
Either a ruler or pile of coins can be used to set the setting bar to the correct position. You are measuring the distance
between the bar and the underside of the button head screw (‘XX’ in the Image below).
DO NOT ATTEMPT TO USE THE DETHATCHER CASSETTE OR BRUSH CASSETTE ON
TOO LOW A SETTING AS THIS WILL DAMAGE THE BLADES AND BRUSH. DO NOT
ATTEMPT TO SCARIFY ON A LOW SETTING WHEN GROUND CONDITIONS ARE DRY AS
THIS MAY CAUSE THE CENTRIFUGAL CLUTCH TO SLIP.

The FT cylinder is xed in
position in self-aligning
bearings with aluminium
housings spigotted to the
side frames. The bottom
blade assembly is
adjusted up and down by
using a knurled knob
system.
To operate this system
rstly slacken the two locknuts
on the adjuster stems – The Lock Nut (A) is directly on top of the Knurled Knobs (B). Use a 9/16 AF spanner. Each
knurled knob has a decal to indicate ON or OFF cut. ON cut brings the bottom blade closer to the cylinder. OFF cut
moves it away.
A = Locknut (9/16” Spanner)
B = Lubricate occasionally with Oil
C = Circlip
Rotate the knurled knobs to gain light contact between the shear blade and cylinder on
both sides of the cassette. The adjustment should be made so that the cylinder will spin
with a light audible contact with the bottom blade. Check the setting using thin paper
along the length of the cylinder adjusting until it cuts along its whole length.
When a satisfactory set is achieved tighten the lock nuts whilst holding the knurled knob
rmly (to stop it turning), recheck adjustment.
Do not set the cylinder hard on, as this will cause excessive wear of the cylinder, bottom
blade the drive system and increase fuel consumption.
General Adjustments
CUTTER SETTING ADJUSTMENT
For cutter cylinder cassettes (5 or 9 blade units).
For a full view of the setting operation we suggest you remove the cassette from the machine and place on the back at
edge of the frame at a comfortable height. It is now possible to make adjustments in the machine without cassette
removal should you prefer.
CYLINDERS AND BOTTOM BLADES ARE SHARP, WEAR GLOVES TO PROTECT YOUR
HANDS AND FINGERS.

Removing The Cassette Unit
To remove the cassette unit for maintenance or to exchange cassettes the following
procedure should be followed:-
1) Unscrew the hand wheel of the retaining pin for about half-an-inch (13mm) until the
pip end is inside the nut on the side frame.
2) Slide the cassette unit along the tie bars as far as it will go until the cutter nut and
coupling is clear of the three pins in the driving coupling.
3) Remove the unit from the chassis by lifting in a swinging motion from the back.
To replace the cassette unit :-
1) Place the front slots of the cassette unit frames on the two front retaining pins seen
projecting from inside each frame.
2) Carefully lower the unit in a downward swinging motion until the rear slots of the
cassette unit frame rest on the cross tie bar.
3) Move in a lateral direction away from the retaining pin until the three holes of the
cassette nut and coupling are in full engagement with the three pins of the driving
coupling.
4) Screw up the hand wheel with the retaining pin, engaging the hole in the side frame
on the opposite side. Do not over tighten.

FT & Super Six SP20001_REV_6
Routine Maintenance
DRIVING BELTS
The main drive to both rear roller and cassette is via hard wearing TBA poly-V type belts
which provide for smooth trouble free operation. To ensure the best performance the
following instructions should be carefully followed.
Belt tension is the single most important factor necessary for long, satisfactory service
life of any belt drive.
Under-tensioning leads to belt slip causing rapid wear; over tensioning means
excessive strain on belt and bearings. Between these two extreme conditions is a
reasonable range of tension within which the belt will operate. Belt tension can be
assessed by the ‘deection’ method.
CORRECTION CAN BE MADE BY ADJUSTMENT OF THE BELT TENSIONERS. REMOVE
THE DRIVING BELT COVER. THE BELT TENSIONERS ARE RETAINED IN A SLOTTED
HOLE ALLOWING ADJUSTMENT TO BE MADE ONCE THE HOLDING HEXAGON
HEADED BOLTS HAVE BEEN LOOSENED. WHEN ADJUSTED CORRECTLY THE
TENSIONERS SHOULD STILL ROTATE EASILY WITH FINGER PRESSURE. ENSURE THE
TENSIONER BOLTS ARE SECURE BEFORE REPLACING THE COVER.
NOTE
“Belts will be sufciently tensioned if the deection force applied at mid span to produce a deection equal to 16mm per
meter of span distance falls between 5 and 9 Newtons per Rib” (TBA Belting).
In practical terms this relates to about 5mm of deection under moderate nger pressure on the non tensioner side.
If tting new belts it is advisable to observe the drive for the rst 20-30 minutes. It may be necessary to make an
adjustment to compensate for the normal drop in tension during the run-in period.
FOR BELT DETAILS, REF. 1.02 (Pg. 19)
Do not overtighten belts as this may cause excessive wear on the dog clutch.

Routine Maintenance
BRAKE BAND ADJUSTMENT (Rear Axle Drive)
The brake band assembly is mounted on the end of the rear axle spindle on the right
hand side of the machine. The assembly comprises a cast iron drum inner member,
which is stopped or braked with a lined steel brake band. This operates dry and no
lubrication of any kind is required.
Adjustment is provided for tightening the band on the inner member should this be
necessary through wear. The procedure to take up any slack is as follows :-
1. Remove the clutch cover by unscrewing the two hexagon headed screws seen on the
outside of the cover.
2. Unscrew the lock nut on the adjuster screw situated between the two clutch band lugs.
ENSURE THE LOCK NUTS ARE TIGHT AND SECURE AND CHECK OPERATION IS
SATISFACTORY BEFORE REPLACING THE CLUTCH COVER AND SCREWS.
NOTE
Adjust Here
Adjustment of the brake band can be set to suit your preference but always ensure that there is sufcient free play so that
when the engine revs are increased the machine does not move in any way until the lever is pulled up.
On some models there is adjustment on the handle grip itself to allow any wear to be taken up.

15
FT & Super Six SP20001_REV_6
General Lubrication
REAR ROLLER
The centre section gear case chamber of the rear roller is an assembly in two halves and contains the epicyclic gear
system, which runs in an oil bath.
The chamber is charged with gear oil EP 90 before the machine leaves the works and should require no further lling
during the cutting season. If in every day use then a topping up charge of about one egg cup full every two months may
be appropriate.
DO NOT OVERCHARGE. AT NO TIME SHOULD THERE BE MORE THAN 100CC OF OIL
IN THE CHAMBER.
WARNING
Access to the chamber is gained by unscrewing the hexagon screw found in the recess of the centre section of roller.
Clean away all dirt and grit before removing this screw. On replacing the screw, make sure it is tight and secure.
Recommended grade gearbox oil EP90.
RATCHET PAWLS AND DRUM HUBS OF THE REAR ROLLER (Every 2 Months)
Projecting from the side face towards the centre of each outer drum will be seen two
grease nipples which provide access for lubrication to the rear roller driving pawls and
the drum hub bearing sleeve.
A small charge of light grease should be applied every two months.
FRONT ROLLERS
The bearings used on the front rollers are pre packed with grease and rubber shielded,
therefore requiring no additional greasing.
CYLINDER CASSETTE BEARINGS (Every Day)
To apply lubrication to the cylinder cassette bearings it is rst necessary to remove the
cassette unit from the chassis as described on page 9.
Projecting from each bearing cover will be seen a grease nipple through which a small
charge of grease should be applied using the grease gun
MEDIUM GREASE = GOOD QUALITY
SCARIFIER / DE-THATCHER / BRUSH CASSETTES
No grease or oiling is required.

16
FT & Super Six SP20001_REV_6
General Lubrication
DOG DRIVE (Every Day) - VERY IMPORTANT
Apply a small squirt of lubricating oil (2-3 drops) directly into each hole in the top of the
drive shaft cover. This keeps the clutch slippers lubricated.
CONTROL LEVERS AND CABLES (Every 2 Months)
To keep the controls free from rust and corrosion apply a small charge of oil to the
throttle and clutch control levers every two months. Oil ow can be assisted by working
the levers open and closed a few times after the lubrication is applied.
FRONT ROLLER ADJUSTERS (Every 2 Months)
Apply a small quantity of copper grease or similar to the adjuster studs to prevent corrosion and ease adjustment.
Lubricate
Daily
Storage
The machine should always be kept in a clean dry place, free from condensation. After use ensure that the machine is
thoroughly clean, dry and free from grass and mud. Before off season storage smear a thin layer of grease on to the
cutter blades and the shear blade.
Under no circumstances must the machine be steam cleaned as this may remove grease from the pre packed bearings.
Because of the nature of lead free petrol we recomend that if the machine is being left unused for more than 2 weeks the
carburetor is run dry. Allow the engine to run out of fuel with the fuel tap switched off.
