Assembly Instructions
Blade Assembly
Most sickle bar mowers are shipped disassembled and packed in crates therefore before
proceeding to connect unit to tractor is necessary to connect blade to three point hitch and main
frame.
1. Blade assembly for sickle bar mowers with mechanical lift (FIG. 3.1). Remove from support (1)
into frame (2) and fasten with same snap ring and segger ring. Screw or pull (3) and connect
cable (4) to link (5).
2. Blade assembly for sickle bar mowers with hydraulic lift (FIG 3.2).
Remove from support (1) pulley (3), snap ring E 80 and seeger ring 80. Insert support (1) into
frame (2) and fasten with same snap ring and seeger ring.
Screw black ori pulley (3). Mount ori upper pin of support (1) fork hinge (4), insert cylinder shaft
(5) and fasten with screwTE 14x65 (6).
3. Mount the three belts and external protection guard.
4. Mount lateral deflector (1) (FIG. 3.3) and fasten with screwsTE 12x50 (12), washer 12 (13) and
self-locking nut 12 MA (14). Insert screwTE 12x90 (7), washer 12 (8), spring (9) and fasten with
self-locking nut (11)
5. For the models BFS 240/H, BFS 270/H insert hydraulic shaft position 5, figure 3.4 to link position
7, always in figure 4.

Assembly - Sickle Bar Mower
Attaching the Sickle Bar Mower to theTractor
Before connecting unit to the tractor make sure that all parts are properly in place and that all bolts
and nuts are well tightened and all parts correctly lubricated.
Make sure that pins A (FIG 4.1) of three point hitch are clean and greased, connect to tractor link
arms B and block with pins C.
Important: According to the type of tractor you have use either internal or external pins A (FIG 4.1)
so that internal skid of sickle bar mower A (FIG 4.2) remains behind tractor wheel.
Connect PTO shaft A and three-point hitch top link B (Fig 4.3).
Attach chain hitch plate to three-point hitch (FIG. 4.4) A or use U bolt (supplied) to connect chain to
tractor. Make sure that chain is connected at approximately same height of three-point hitch and to
a rigid location of tractor

Tractor Linkage
Using hydraulic lift raise sickle bar mower and adjust chain (FIG. 4.4) so that PTO shaft is in
horizontal position.
Clearance of lower part of sickle bar mower frame should be of 15.7" (40 cm) from ground (FIG 4.5)
After the adjustment is completed mark chain ring in order to have always the same cutting height.
Raise foot support (FIG. 4.6) and bring into working position and fasten with split pin A.
Tractor Linkage of Sickle Bar Mower with Mechanical Lift
Connect plate with hole A (FIG 4.7) to left pin of lower tractor arm. If this is not possible use U-bolt
(supplied) and fasten to lowest part of tractor structure with hole. Stretch cable and fasten chain B,
(FIG. 4.7) using hydraulic lift of tractor control so that right extremity of sickle bar begins to raise
when skid is about 6" (15 cm) from ground (FIG. 4.8). If further adjustments are necessary move
chain rings B, in plate with hole A, (FIG. 4.7). After correct position is obtained mark chain ring so
that you always have the same height.The weight of sickle bar mower on ground is absorbed by
compensation spring A, (FIG 4.9) whose stretch can be adjusted by turnbuckle B.This feature is
also mounted on units with hydraulic lift.

Tractor Linkage of Sickle Bar
Mower with Hydraulic Lift
Connect hydraulic hose to tractor. Mount
on tractor and close oledinamic cylinder
using distributor lever.This will raise unit
completely.
Never close hydraulic cylinder if release
support E has not been turned downwards
(FIG 4.11)

Hydraulic Kit Assembly Instructions
To transform your sickle bar mower from mechanical lift to hydraulic lift refer to Figures 4.10 and
4.12.
Mount lift attachment A for hydraulic cylinder (if not already mounted) after having removed
mechanical lift attachment.
Connect cylinder B and fasten with pin C and respective roll pins 6x30. Insert fork D and fasten to
cylinder shaft using screw and nut 14x65 after having removed link position 16, lift frame ledge
position 19 and the two spacers position 20 as all shown on table 5.
If you have a BFS/240-270H model mount fork E as shown in (FIG 4.12), connect hydraulic hoses.

Operation - Sickle Bar Mower
Operation Instructions
Cutting Speed
For a good quality cut we recommend that you
engage PTO speed between 400 to 450 rpm.
Do not operate over 540 rpm and do not
overspeed. Keep tractor speed as high as
possible between 10 and 15 km/h (6 to 10 m/h)
to facilitate grass discharge. In order to avoid
clogging up of blade we recommend that the
sickle bar mower rests as close as possible to
grass to be cut especially in the presence of
flattened grass. Always be aware of crop and
field conditions. In rough field conditions speed
should be reduced.
Safety Release Breakaway Latch
Sickle bar mower is protected with a safety
release mechanism. If an obstruction is hit the
cutter bar will swing back. Stop tractor and do
not raise sickle bar.Turn off tractor engine and
make sure that PTO shaft is not disengaged,
if so, engage PTO shaft in correct position.To
reset safety release back up tractor until latch
breaks away too often adjust spring B using nut
A (FIG. 5.1) and tighten half turn at the time.
BeltTension
Check periodically belt tension. Unscrew small
window opening on protection guard A (FIG.
5.3).
If necessary tighten belt using nut and
conternut A (FIG 5.2).

Operation - Sickle Bar Mower
Cutting Height Adjustment
Lower sickle mower on ground and use upper third point hitch arm A (FIG 6.1) until the desired
cutting height is obtained.
In rough ground conditions or on stony terrains make sure that cutting height is adequate to avoid
damage to knives blade.
Raising and Lowering of Sickle Bar Mower Blade
Before carrying out any raising and lowering operations make sure to disconnect PTO shaft from
tractor make sure that all moving parts have come to a complete stop.
Road transport:To transport the mower on a road or from a field to another raise mower to reduce
overall length.
Important: Remember always to turn release support E upwards before raising mower and before
road transport (FIG 7.3).
Once sickle bar mower blade is in vertical position block using tie rod hook A (FIG 7.1) which was
previously removed. Fasten tie rod hook A with handle B and insert split pin C and cover blade
with protection guard cover. (FIG 7.2).

Operation - Sickle Bar Mower
Working Position
Lower tractor using hydraulic lift.
Get off tractor and remove tie rod hook A (FIG. 7.2) and piece in position on frame (FIG 7.1). Lower
sickle bar mower blade.
During working operations make sure that release support E (FIG. 7.3) is in downward position.
Remember always to turn release support E upwards before disconnecting from tractor.This will
keep pins in horizontal position and facilitate successive linkage operations.
