1.4 Putting in service
Nobody should stand in between the tractor and the machine when you change the machine from
central mount- to offset-position.
1.4.1 Fitting to the tractor
The KT 3D-Flex machines are equipped with the pins are coupled to the
tractor. Secure these pins with the supplied retaining clips. The 3D-Flex is
standard a front version, where the top link pin can be placed in one of the
holes on top of the bracket for optimal adjustment.
Then connect the PTO and hydraulic hoses to the tractor when it is
completely switched off.

9
1.4.2 Road transport
During road transport, the flail mower must with the parallelogram(red arrow) arms be
positioned in the middle of the tractor. Then lock the machine oscillating by pressing
the cylinders (green arrow) on (hydraulic) pressure, so that it is pressed against the
buffers.
During road-transport the machine is carried by the tractor 3-point linkage. It is not allowed to
carry the machine in offset position during road-transport!
1.4.3 Cutting height
The cutting height can, if necessary, be adjusted with the rear roller as follows:
By re-setting the upper fixing bolts in one of the other adjusting holes of the
frame and / or adjusting plate. The highest hole in the frame will give you the
lowest cut ± 40 mm (1,6") and the lowest hole in the frame the highest cut ± 100
mm (3,94 ).
The machine front-side should always be carried by the tractor 3-point linkage.
1.4.4 P.T.O. shaft
The P.T.O. shaft supplied with the machine has a retracted length of 1610 mm (± 5'3”).
This length is correct for most of the popular tractor sizes. However it is strongly recommended to check the proper
length of the P.T.O. shaft before operating the machine, and if necessary to shorten it according to the instructions
attached to the P.T.O. shaft. Check the proper length as well in transport- as in work positions!
Check the length of the overlap of the protection elements; this should be at least 50 mm (2”).
The guard tube of the P.T.O. shaft must be secured against rotation by the little chains.
When the machine is disconnected from the tractor the P.T.O. shaft should rest in the corresponding chain of the 3-point
bow.
Remark: Using an oversized tractor (over 80HP) it is strongly recommended to install an overload clutch.
This clutch should be adjusted at the following value:
- KT-245, -270 and -300, P.T.O. Speed 1000 RPM 1200 Nm ( 10.621 inlb.)
- KT-320, P.T.O. Speed 1000 RPM 1500 Nm ( 13.276 inlb.)
1.4.5 Adjusting work position
During work, the machine must be adjusted in a free-moving position. This can be achieved by adjusting the height
of the lifting arm pins at +/- 50cm from the bottom (red arrow). The machine must be adjusted flat by the top link,
so that the parallelogram system is horizontal and has a free movement of +/- 15cm (green arrow).

10

11
1.4.6 Bottom pressure
The machine is standard equipped with a mechanical bottom relief by means of
feathers. The springs can be adjusted in pretension by adjusting the bolt height.
1.4.7 Wheel slip tractor
In order to achieve optimal wheel slip during plowing, is it important that there is
sufficient weight in the front lift to have the optimal wheel slip of the tractor. This
can be adjusted with the bottom pressure of the machine combined with adding or
removing extra weights (green arrow) to the parallelogram arms.
When weights removed or added, lifting equipment must be available. The weights
weigh 25 kg(+/- 55lb) each.
1.4.8 Gearbox
To protect the oil to drain, the breather is replaced by plastic plug during transport from manufacturer to the farmer.
Before taking the machine in service the plastic plug must be replaced by the breather. During transport the breather is
fixed to the drive shaft of the gearbox.
1.4.9 De machine van de tractor afkoppelen
The machine must be placed on the supports and rear roller. Then place the hydraulics
in free-flow position, so that the 3-point suspension rests on the frame. Switch off the
tractor to disconnect the PTO and remove the pins from the top link and lift arms.
1.4.10 Transport
If the flail mower needs to be unloaded / moved, use a lifting
device that is suitable for the weight of the flail mower concerned
(see technical specifications).
The machine must be lifted with a lifting strap on the lifting eyes
welded to the 3-point hitch.
1.5 Precautions
Every time before you take the machine in service the following items have to be checked:
• The machine and the tractor checked for operational and road safety
• That all bolts and nuts are sufficiently tight. Retighten if necessary
• Oil level in gearbox (chapter 1.7)
• V-belt tension (chapter 1.8)
• Condition of cutting flails (chapter 1.9)
• Grease points (chapter 1.10)

12
1.6 Driving speed
Depending on quantity, size and character of vegetation and working conditions the recommended driving speed is 4 – 8
km./h. (2,5 – 5 M.P.H.)
1.7 Gearbox
Before operating the machine and further at regular intervals, the following points should be checked:
• Oil level:
This is correct when the oil comes out of the bottom hole (red arrow) of
the oil level plug. This plug is hidden behind the protection cover on the
PTO side.
• Breather:
The air vent (red arrow) must not be clogged. The convex cap must be
easy to press. Clean if necessary by blowing through the air vent from the
“inside”.
Renew oil after the first 20 working hours and further after every 100 working hours, but at least once a season.
To renew the gearbox oil handle as follows:
Remove the breather and the drain plug and drain the oil.
*** Collect the old oil, e.g. in a bucket, for environment friendly disposal. ***
Refit the oil drain-plug and pour 1 liter (± 1/2 gallon) diesel-oil through the breather hole in the housings. Clean the
internal gearbox (by washing with the diesel oil) by turning the V-belt pulley a few times by hand.
Then drain and collect the dirty diesel-oil and refill the gearbox to the required oil-level and refit the breather.
Fill up only to the proper level and use always the same oil.
Recommended is synthetic gear-oil EP-320.
*** Note: Allow the oil enough time to sink through the bearings.
Wipe off excess oil to prevent it reaching the V-belts as oil and grease cause unnecessary slipping and extra wear.
To replenish or replace the correct oil, if possible Mobil EP-320 or an equivalent oil.
Viscosity base oil at 40°C 320 Cst.
Temperature range -24°C tot 240°C
DIN 51517-3 : CLP PG
ISO 12925-1 CKT
Good pressure properties.
1.8 V-belts
A correct V-belt tension is very important and this should be checked after the
first 2, 8 and 16 hours of service and further on at regular times (at least every
50 hours of service). As a general rule when determining the correct tension, the
V-belts must not be able to turn more than one ¼ turn around their longitudinal
axis.
The V-belts are kept in tension by means of a spring loaded jockey pulley. The
"pressure" of this jockey pulley can be adjusted by the chain of the spring and the
hook on the frame.
Remark: When new V-belts are mounted, always make a test run and check the V-belt tension
again!!!

13
1.9 Flails
1.9.1 General
• Only the use of original PERFECT parts will assure you of a safe service of the machine. So use by replacement only
original "PERFECT" parts.
• Every time before the machine is taken in service the flails should be checked. Are no flails lost, are they still in good
shape?
Replace the flails if necessary by original PERFECT parts, see also chapter 1.7.4. The flails have to be replaced
when there is no longer any overlap.
• When the fixing bolts have to be replaced (when the diameter has become less than 17 mm) you should always use
original PERFECT bolts. Bolts M20 x 137, quality 10.9.
• Tighten up the lock-nuts M20 until the bushing in the corresponding "ear" starts to shift.
NO risks, NO experiments with imitation parts, use only original PERFECT parts!
1.9.2 In service
When the machine starts to vibrate the tractor P.T.O. shaft should be disengaged immediately. Check the condition of
flails and flail -rotor.
Replace broken or damaged parts by original PERFECT parts.
1.9.3 P.T.O. / rotor speed
It is only allowed to drive into the field to be mowed at full operating speed, that is standard at 1000 rpm of the PTO.
Optional is 540 rpm possible.
The required PTO speed can be read on the stickers on the machine.
1.9.4 Replacement of flails
• Remove the lock-nuts, the lock washers and bolts
• Replace the flails by original PERFECT flails.
• Replace also the lock nuts and lock washers and also the bolts when the
diameter has become less than 17 mm..
• Use always original PERFECT bolts, lock washers and nuts (bolts
M20, quality 10.9).
• Use the original PERFECT lock washers and fasten the lock-nuts with a
torque of 550 Nm (4.750 inlb.).
