1.4 Putting in service of a unit
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 !
The machine is supplied from the factory without oil in the hydraulic hoses and cylinders, when it is
delivered with the option “hydraulic offset”. Be sure when first time using that no air left in the hoses
and cylinders.
1.4.1 Fitting to the tractor
While the mower is coupled to the tractor nobody should stand in
between the tractor and the machine.
1.4.1.1 Mechanically
The ZF2 mower is coupled to the tractor with the pins, Cat. II. Secure these pins
with the corresponding spring locks.
The top link pin, at the mowers side, should always be put in the round hole on
top of the 3-point bow!
The pull cord of the transport safety lock, should be secured properly in the
tractor cabin.

9
Optionally, the ZF2-210 or -240 mower can be equipped with a so-called hydro-lift
frame. The suspension trestle can be lifted on one side by means of a hydraulic
cylinder. This raises the gearbox / drive side of the cutting head ± 300mm. This can
be very practical when mowing a shallow ditch / short slope.
1.4.1.2 Hydraulically
-The hydraulic hose of the cutting head cylinder must be connected to a single or double acting control
valve.For the machine to work properly, this must be a control valve with a "floating position".
*** If the tractor is not equipped with a control valve with a floating position, it may be necessary to connect
an accumulator to the cutting head cylinder.
-The hydraulic hoses of the miter cylinder must be connected to a double-acting control valve.
-The hydraulic hose of the hydro-lift must be connected to a single or double acting control valve..
1.4.2 Transport Safety Lock
For safety reasons the cutting head has to be "locked" during road transport.
1.4.2.1 Lock cutter head:
-put the mower in the "minimum" offset position
-re-tract the cutting-head ram so the cutting head comes to a
practical vertical position
-pull the cord as long as you will hear a clear "click"
-check if the cutting head is locked.
Put the valve of the cutting head ram in the return position
and move the mower to the offset position and stop this action
suddenly.
If the cutting head does not come "down" the lock is active and the mower
is ready for road transport.
1.4.2.2 Un-lock cutter head:
-re-tract the cutting-head ram ones more
-pull the cord and put the cutting-head ram in the return position (meanwhile you put the mower in the
maximum offset position)
-when the cutting-head comes down (at least 10º) you can release the cord tension
As long as you do not pull the cord when the cutting-head is in vertical position you can move the cutting-
head up and down freely!
1.4.3 Obstacle Safety Device
The adjustment of this safety device is set so it will not come in action during
normal service.
By the special layout of the device it does not matter in which offset position the
mower is set, in all offset positions the is "break-force" the same.
By the "Perfect" solution the mower is always running at a right angle to the
driving direction (less force on the roller bearings).
If necessary you can change the adjustment of this Obstacle Safety Device.
Handle as follow:
-remove the Power belt cover
- remove plate
-tighten the lock nut until the bolt comes loose in the spring housing
-remove the nut
-remove the bolt
-take away the nut

10
-remove the spring housing
-add or take away as many spring washer as you like
-re-assemble all the parts in the opposite way
Mower is now ready for service.
1.4.4 Cutting height
You can adjust the cutting height by moving the upper bolts of the rear roller The
upper hole in the frame will give you the lowest cut ± 40 mm (1½ ") and the lowest
hole in the frame the highest cut ± 90 mm (3½").
How to handle:
-un-tighten the 4 lock nuts, Det. 12, at both sides of the rear roller
-move the 2bolts, the nearest to the roller, one hole by one hole (left / right, left /
right) in one of the other holes in the adjusting plate until the wanted cutting
height is found
-re-tighten the lock nuts, Det. 12 ( 225 Nm, 1970 inlb) very tight
1.4.5 P.T.O. shaft
The P.T.O. shaft supplied with the flail mower, standard with overrunning clutch, has a retracted length of ± 1250 mm
(4'1").
This length is correct for most of the popular tractor sizes. 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.
Always speed up the P.T.O. shaft to the prescribed speed of 1000 RPM before starting to cut.
The correct speed is indicated on the gearbox cover.
Remark: Using an oversized tractor it is recommended to install an overload clutch. This should be adjusted at the
following value of:
-ZF2-150, -180, -210 →1000 Nm
-ZF2-240 →1330 Nm
1.4.6 Gearbox
Each time you take the flail mower in service you have to check the oil level of the gearbox. See chapter 1.6 how to
handle.
During transport from manufacturer to the end customer is in some occasions the breather replaced by a plastic plug. In
such a case this plug has to be replaced by the breather before the machine is taken in service. During transport the
breather is fixed to the drive shaft of the gearbox.
1.4.7 Transport
If the flail mower has to be unloaded / moved, use lifting equipment
which is suitable for the weight of the flail mower in question (see
technical specifications). The machine must be lifted with a lifting
strap on the pin for the top link coupling and the 2 lifting eyes.
During road transport, the machine is lifted by the
tractor's lifting device. It is strictly forbidden to
transport the machine on the road in a miter position.

11
1.4.8 Overload coupling
To absorb extreme resistances from the flail shaft without damaging the gearbox, a flexible element is mounted between
the gearbox and flail shaft. This also absorbs the alignment difference between the gearbox and flail shaft. The maximum
tolerance is 1 mm in line with the axes and a maximum angle of 1 ° degrees
Should it necessary to replace the flexible element after damage, proceed as follows.
•place the machine unfolded on a flat surface
•remove the protective cover
•disassemble / remove the remaining (broken) bolts
•remove the flexible element
•check if the hubs, gearbox side and on the flail shaft are still good. Otherwise
replace it
•check that the gearbox output shaft and / or flail drive shaft are not damaged.
Otherwise replace it
•check that the shafts of the gearbox and flail shaft are properly aligned
•fit the new parts
•the shear bolts of the flexible coupling must be able to be mounted smoothly, otherwise the shafts are not aligned
•mount the protective cover
1.5 Mechanical check-up
Every time before you take the machine in service the following items have to be checked:
•service and traffic precautions items of the mower and the tractor
•tightness of all bolts and nuts. Re-tighten if necessary
•oil level in gearbox (chapter 1.7)
•pré-tension of the Power-belt (chapter 1.8)
•condition of cutting flails (chapter 1.9)
•grease points (chapter 1.10)
1.6 Driving speed
Depending on quantity, size and character of vegetation and working conditions the recommended driving speed is 2 –5
km./h. (1½ –3 M.P.H.).
1.7 Gearbox
See also page 106.
Before operating the machine and further at regular intervals, the following points should be checked:
•Oil level:
he oil level is correct when the oil level just reaches the hole(red arrow) of the plug in
the cover.
•Breather:
the breather(green arrow) should be free of obstruction. The cap must be slightly
compressible. Clean the breather by blowing through from the inside.
Renew oil after the first 50 working hours and further after every 250 working hours, but at least once a season.
To renew the gearbox oil handle as follows:
Run the machine until the oil is warm and remove the breather. Remove the drain-plug at the bottom side of the gearbox
housing and drain the old oil.
*** Collect the old oil, e.g. in a bucket, for environment friendly disposal. ***
Refit the oil drain-plug and pour 1 litre diesel-oil through the breather hole in the housing. Clean the internal gearbox, by
washing with the diesel oil, by turning the flail rotor a few times by hand. Then drain and collect the dirty diesel oil and
refill the gearbox to required oil level and refit the breather.
Fill up only to the proper level, and always use the same oil. Gear-oil is advised, or SEA-120 in extremely warm
climates.

12
*** 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 for a ZF2-150, -180, -210, if possible Mobil EP 320 or an equivalent oil.
ISO 12925-1 Type CKC
Viscosity base oil at 40°C 320 Cst.
Temperature range -24°C tot 240°C
Good EP properties.
Use for a ZF2-240, if possible Mobil SY 320 or an equivalent oil.
ISO 6743-6 Type CKS
Viscosity base oil at 40°C 320 Cst.
Temperature range -30°C tot 230°C
Good properties.
1.8 Power Belt
A correct Power-belt tension is very important and should be checked after the first 2, 8 and 16 hours of service en
further on at regular times (at least every 40 hours of service). Re-tension if necessary.
To check the correct pré-tension of the Power belt you have to take the "length" of the tensioning spring. The opening to
check the length of the spring will you find at the left bottom side of the main support frame.
min. 133 mm
max. 138 mm
ZF2 - Instelling voorspanning Powerband
ZF2 - Adjustment of Pré-tension of Power Belt
ZF2 - Einstellung Vorspannung Kraftband
ZF2 - Réglage de la tension de la courroie "Powerbelt"
Fig. 1 Bottom view of Power Belt tension set.
The pré-tension of the Power belt is correct if the length of the spring (see the above picture) is in between 133 and 138
mm.
The length of the spring may never be less than 133 mm, this means too much strength on Power Belt / shafts /
bearings!!
Has the length of the spring become more than 138 mm you have to re-tighten the spring.
Handle as follow:
-remove the Power belt cover
- remove plate
-untighten nut
-tighten nut until the spring has a length of 133mm
-re-tighten the contra nut tightly
-re-assemble all the parts in the opposite way

13
1.9 Flails
1.9.1 General
•Only using Original Perfect Parts will assure you of a safe service of the flail mower.
•Every time before the machine is taken in service the flails should be checked. Are no flails lost? Replace the flails if
necessary by original Perfect parts, see also chapter 1.7.3.
•Check if the flails are not broken or cracked.
•If the diameter of the bolts has become less than 17 mm you have to replace also the mounting-on bolts. You should
always use original Perfect bolts M20 x 90 or M20 x 137, quality 10.9.
•Use the original Perfect lock washers and fasten the lock-nuts with a torque of 550 Nm (4800 inlb)
•The flails have to be replaced when there is no longer any overlap.

•Put the new bushing in the flange of the main support frame
•Drill a hole ø 3 mm in the bushing / flange (picture nr. 1)
•Put a hollow pin in this hole so the bushing cannot turn anymore in the flange (picture nr. 2)
•Grind the protruding end of the pin off so the in-side of the bushings becomes nice and smooth
•Drill a hole ø 3 mm at the location of the grease canal (picture nr. 3)

1.10.11 Sliding part Hydro-Lift
The sliding part of the sliding device should be greased every 8 hours of service.
1.10.12 General grease advise
•clean the grease nipples properly before starting to grease
•do not use too high grease "pressure". Too high grease pressure could damage
the seals!
•grease interval depends strongly on circumstances
•always re-grease all point after you washed the machine!
•always use a good quality ball bearing grease EP-2, or equivalent.

16
•wipe-off excess grease to prevent it reaching the V-belts as oil and grease cause unnecessary slipping and extra
wear.
If possible lubricate with Total Lical EP/ ELF EPEXELF 2 or an equivalent grease.
Viscosity base oil 40°C 190 - 220 Cst.
Thickener Lithium/Calcium compatible.
Temperature range -25°C tot 130°C
Good EP properties.
