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 machine is suitable for every standard 3-point linkage Kat. I or II and is coupled to the tractor with stepped pins.Do
not forget to securer these pins with the also supplied springlocks.
•3-point model:
When the tractor and the machine are standing on a flat surface the
machine-sided pin of the top link should be adjusted just in the middle of
the corresponding slot hole of the 3-point bow. Doing sothemachine, atthe
front side lifted by the tractor 3-point, can follows the contours of an
uneven field freely, this gives a nice equal cut and the machine will not be
overloaded.
•Front model:
On the front mounted flail chopper the machine-sided top link pin has always to be fitted in the round hole of
the 3-point bow. When the tractor and the machine are standing on a flat surface the tipping possibility between
supporting frame and main body should be in the middle position of itsstroke. Furtheron the top link shouldbe
as parallel as possible with the lower links. Doing so the flail chopper will be lifted at the front-side while it is
also resting on the rear roller. Now the machine will be able to follow the contours of an uneven field freely
which gives a nice and equal cut and the machine will not be overloaded.
If you would like to block the "tipping" possibility between the main body and the supporting frame you have
to turn the "blocking" plate 180º.
1.4.2 Road transport
During road transport, the flail mower must be positioned in the middle of the tractor through the hydraulic offset
which is optional possible.
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 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 ± 25 mm (1") and the lowest hole in the frame the highest cut ± 100
mm (4").
The machine front-side should always be carried by the tractor3-pointlinkage
(on the front model by the supporting bracket).
1.4.4 P.T.O. shaft
The P.T.O. shaft supplied with the machine has a retracted length of 920 mm (± 3') for 3-point mounted modelsand 1050
mm (3'5") for the front mounted models.
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.

11
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 (up to -180 over 75Hp, -210 over 100Hp) it is recommended to install an
overload clutch.
This clutch should be adjusted at the following value:
- BG2/BK2-105, -120, -135, -150, -180 P.T.O. speed 540 RPM: 1450 Nm (12.750 inlb.)
- BG2/BK2-210 P.T.O. speed 540 RPM: 1850 Nm (16.400 inlb.)
*** Optional: P.T.O. Speed 1000 RPM 1200 Nm ( 10.500 inlb.)
1.4.5 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.
1.4.6 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 3-point hitch and lifting
eye.
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)
1.6 Driving speed
Depending on quantity, size and character of vegetation and working conditions the recommended driving speedis 2 –5
km./h. (3/4 –3 M.P.H.). However, it is up to the operator to respond to the circumstances at all times to prevent
blockages / damage the machine. The diameter of the pruning should not be greater than 90 mm (3 ½ ")
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 (green arrow) of the oil
level plug.
•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 (you can reach the drain plug from the in-side of the main

12
body).
*** Collect the old oil, e.g. in a bucket, for environment friendly disposal. ***
Refit the oil drain-plug and pour 1 litre (± 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 gear-oil EP-320 or SG-150(Front version) in extremely warm climates.
*** 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.
On the Type BG2/BK2-3-point 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
Good pressure properties.
On the Type BG2/BK2-Front replenish or replace the correct oil, if possible SG-150 or an equivalent oil.
Viscosity base oil at 40°C 150 Cst.
Temperature range -35°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). A general rule for the determination of the correct belt
tension is: properly adjusted belts cannot be twisted more than a quarter of a longitudinally turn (by thumb and
forefinger).
1.8.1 Standard 3-point machine
The (side) 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.
1.8.2 Optional Front version machine
The "middle" V-belts of the machine are tensioned through a bolt(red arrow). First,
loosen the 4 bolts (green arrow) on the gearbox and as follow adjust the bolt until the
correct tension is reached. Finally tighten the bolts of the gearbox.
When changing the V-belts, is it necessary to loosen the 4 bolts (green arrow) on the
gearbox so that it can move. Then move the gearbox with the bolt (red arrow) so that
the V-belts can be disconnect. Replace the V-belts, adjust the bolt until the correct
tension is reached. Finally tighten the bolts of the gearbox.
Remark: When new V-belts are mounted, always make a test run and checktheV-belttensionagain!!!
