Attaching the BFM Series Finish Mower
Carefully read this instruction manual and the manuals of the tractor and
PTO shaft manufacturer. All mowers are built to be attached to any tractor
equipped with a three-point lift of the correct category and with suitable
ball ends.
Before attaching the equipment to the tractor, make sure that the ground is
smooth and flat and that nobody is standing between the tractor and the
mower; slowly move the tractor towards the mower by aligning the tractor
lifter arms with the two mower coupling side pins; turn the engine off and
pull the brake.
It is possible to adjust the attachment position by releasing the pins, A
and modifying the position of the plates B.
Connect the tractor top link to the third upper point by removing the pin located between the two plates, inserting
the top link and securing it by means of the pin.
Adjust the top link so that the upper part of the frame is parallel to the ground. Block all the linking parts by means
of the sway chains or arms.
Make sure that the central unit axis (case/bevel gear pair) is parallel to the ground, thus minimizing the stresses on
the power take off and increasing the working life of the equipment.
Before installing the PTO shaft make sure that the RPM rating and the direction of rotation match those of the
tractor. Carefully read the PTO shaft and tractor instructions.
Furthermore, accurately read the instructions of the manufacturer of the PTO shaft and of the tractor. Before
starting any activity, make sure that the guards are installed on the power take off of the tractor and PTO shaft.
Make sure that they cover the PTO shaft throughout its length.
Operating Instructions
Warning: When attaching the BFM Series Finish Mower, Never allow anyone to stand
between the BFM Series Finish Mower and the tractor. Serious injury or death can occur!

Attaching the PTO shaft:
Before installing the PTO shaft make sure that the RPM rating and the direction of rotation match those of the
tractor. Carefully read the PTO shaft and tractor instructions. Before operation, make sure that the guards are
installed on the power take off of the tractor and PTO shaft. Make sure that they cover the PTO shaft
throughout its length. Note: The PTO shaft may be too long and require shortening. See “Shortening a PTO
driveline” below.
Press the locking pin on the PTO yoke and slide yoke on to the PTO of the tractor until the pin seats. Pull on
PTO shaft to make certain it is locked in place. Repeat the procedure for the machine end. Attach the PTO
cover’s safety chains to a stationary part of the tractor. Leave some slack in the chain to accommodate
movement.
Shortening a PTO driveline:
1. With the machine attached to the tractor’s 3-
point hitch, and the PTO shaft not installed,
separate the PTO shaft. Attach the machine
end to the machine and the other end to the
tractor PTO input shaft.
2. Raise the machine by using the tractor’s
hydraulic 3-point hitch to its maximum lift
height.
3. Hold the half shafts next to each other and
mark them so each end is approximately
1/2” from hitting the end of the telescopic
profiles.
4. Shorten the inner and outer guard tubes
equally.
5. Shorten the inner and outer profiles by the same length as the guard tubes. Using a rattail file, round off all
sharp edges and burrs. Grease the telescopic profile generously before reassembling.
When fully extended, the tubes must overlap by at least 1/3 of the length of the pipes
(LT). When retracted, the min. acceptable clearance is 1-2 cm (3/8”-3/4”)

Cutting Height Adjustment:
The cutting height of the equipment depends on the position of the wheels.
If the wheels are raised, the cutting height increases; if the wheels are
lowered, the cutting height decreases.
Make sure that the wheels are set at the same height on both sides.
To adjust the cutting height on the mowers loosen and re- move pin A and
adjust the wheels height according to the bushing B. When the adjustment
is completed, reinsert the pin A.
Adjusting Belt Tension:
In the mowers it is necessary to adjust the belt tension as they stretch;
the correct belts tensioning ensures that the machine works correctly.
To adjust the belts tension:
Remove the two Belt Shields (A).
Loosen the Nuts (B) holding the gearbox in place just enough to allow
the gearbox to be able to move. Turn the bolt C to adjust the tension of
the belts; if you turn the bolt in clockwise direction the belts are
tightened, while turning it counter clockwise they are loosened; when
the belt is tensioned correctly the belt should be able to deflect a
maximum of 10 mm (3/8”). Retighten the Nuts (B). Replace Belt
Shields (A).
Operating Instructions
Caution: These activities must be carried out with the engine off, the power take off
disengaged and the hand brake applied. If needed, lift the equipment and place it on

Maintenance:
Maintenance is crucial for the working life and efficiency of any agricultural equipment. If the equipment is
properly maintained and operated, a long working life and operator safety are assured.
The maintenance intervals indicated in this booklet are provided as a mere reference and are related to normal
working conditions; changes may occur depending on the type of activities, environmental dust, seasonal
factors, etc.
First check
After 50 working hours, check the oil in the gearbox (A) and make sure that all the screws and bolts are
tightened.
Maintenance
Caution: Before injecting lubricating grease into the grease fittings, clean the fittings
to prevent mud, dust, or any other foreign matter from contaminating the grease and
reducing the lubrication effect.
