WHEEL HYDRAULIC MOTORS
Check the level in the reservoir with the motors cold (fig. 4). If more oil is needed, add hydraulic oil OSO 46 (total
quantity: 9,5 litres). Carry out this control frequently.
Caution!
Replace both the hydraulic oil and the hydraulic filter
of the hydraulic motors after the first 500 working hours and then every 1000 working hours.
The oil has to be changed before the first 500 working hours ONLY if:
-
the oil is black;
-
the oil has a whitish colour (it is contaminated with water);
-
there is black coloured residue (partial oil deterioration).
To drain the oil loosen the pipe on the gear pump (fig. 22). To fill the hydraulic engine again in with fresh oil,
unscrew the upper lid of the tank (fig. 4). Pay attention to impurities, which may obstruct the circuit and damage the
machine. When you change the hydraulic oil, the oil filter must be replaced too (fig. 21). Pay attention to the filtering
grade. Do not increase the pressure of the wheel transmission hydraulic system over
280 bar
because this could
damage the hydraulic pump and the hydrostatic motors.
MOWER DECK GEARBOX
Use synthetic oil LSX 75 W 90 (API GL4 + GL5; API MT1 and PG2) quantity 0,112 lt. Replace every 300 working
hours. The gearbox is equipped with a cap on the right side (fig. 23). To remove oil from the gearbox, you must
disconnect the cutter deck from the machine, remove plastic cover, put the cutter deck in vertical position and
unscrew the lid. Make sure that oil will not get on the belt. (For this kind of operation contact our service centres.) If
the operator notices oil losses, check and replace the seals to avoid damages to the whole gearbox.

LUBRICATION POINTS WITH GREASE
Find the lubrication points following the scheme (fig. 2A, n°4, n°3). Lubricate with grease every 50 hours the rear
axle pivots, the pedals, the PTO transmission belt guide pulley, the pivot connected to 2 points of the cutting deck,
the grass-catcher lifting arms.
EMERGENCY AND PARKING BRAKE
The FD900 moves forward via hydraulic motors. To brake it is therefore sufficient to release the forward and reverse
gear pedals (fig. 1 n° 1 and 2). The brake pedal (fig. 1, n° 3) has to be used only in case of emergency. To engage
the parking brake, press the emergency brake (fig. 1 n° 3) and then engage the locking via the appropriate pedal
(fig. 1 n° 5). To disengage the parking brake just press again the emergency brake (fig. 1 n° 3).
Remember to always engage the parking brake, even though the machine is self-braking when the engine is off.
The engine remains on when the operator gets off the machine if the parking brake is engaged.
ADJUSTMENT OF THE PARKING BRAKE AND EMERGENCY BRAKE PEDAL
The brake adjusting screws are located under the platform (fig. 24). The drum brakes are on the front wheels, make
sure the wire does not touch the wheel.
