Implements - Grillo G55 Manual De Uso

Translation of the Original Instructions
ROTARY TILLER - Check the oil level every 50 hours by removing the plug (Fig. 9); the oil must
almost fill the rotary tiller box. If necessary add the same oil as for the gearbox MP 80 W/90.
END OF SEASON MAINTENANCE
Clean the machine carefully; change the engine, gearbox and tiller gearbox oil. Clean the air filter.
Sharpen and grease the blades, replacing them if worn.

IMPLEMENTS

ROTARY TILLER
The rotary tiller is used to break the surface layer of the ground in order to increase its permeability
and at the same time to rid of weeds. Till in first speed if the soil is hard and tough or in second
speed in soft, sandy soil. The working depth can be adjusted by lifting or lowering the central knife
(Fig. 3, A) situated under the rotary unit. The tiller cover position will change at the same time.
Raise the knife to increase the depth. Start work with the knife in its lowest position, and then raise
it if greater depth is required (Fig. 4B). To adjust the tiller at 37 cm, use the appropriate kit (Fig. 4)
N.B. - On hard soils the machine may jump forward. In this case lower the central knife and
fit it into the third hole(Fig. 4B). Check that the blades are fitted correctly (Fig. 9).
ADJUSTABLE FURROWER
This implement (Fig. 23) is specially designed for preparing furrows for sowing and irrigation. It is
mounted using the frame for attachments like a plough on the back of the gearbox. The furrow
width can be regulated from a minimum of 10 cm to a maximum of 30 cm, by changing the position
of the two wings. The depth can be varied from 10 to 20 cm using the lever A (Fig. 24). When
working on particularly hard soils, till before furrowing. The results obtainable can be improved by
fitting the 5.00-10 tyres and if necessary the wheel-weights which increase wheel grip (Fig. 17).
BACK-CUTTER FURROWER
This tool is mounted at the rear of the tiller and works in tandem with it. The furrower is designed to
produce irrigation and seed drills (Fig. 11).
MOWER BAR
The mower bar (Fig. 13) which can be attached to the rotavator has a central or side control. Its
strength and high performance make it the best way of mowing small pieces of land when it does
not make economic sense to purchase a motor mower which would remain unused for most of the
year, while a rotavator can be used with other implements. The mower bar is attached to rotavator
implement frame instead of the rotary tiller. The handlebar must be turned 180° towards the
engine. Before turning the handlebar engage first gear, then release the drive rods. Once the
handlebar has been turned, fit the rods back into the supports. Now that the handlebar has been
reversed the handlebar support mechanism enables the use of all the rotavator gears.
Maintenance: grease the cross pins every 8 working hours through the grease nipples on the
swinging crank. Grease the mower bar swinging bushing every 50 working hours through the
grease nipple under the swinging protection (Fig. 26). Keep the blade ledger plates properly
adjusted. They must be neither too tight, so that they block the blade, nor too loose so that there is
too much clearance between them and the blades. To adjust the ledger plates in both directions
loosen the locking bolts (Fig. 12) and adjust the pressor screw. The ledger plates should be
replaced when worn even if they are still able to apply pressure against the blades. Regulate the
clearance between the blade and the strip by loosening the screws fixing the plates pressing the
strip and moving the strip forward until it touches the bar which supports the nailed blade section.
Then retighten the pressing plates. To remove the blade take off the L-shaped blade coupling by
loosing the two screws (Fig. 26, n° 3) and slip off the blade. Take care to tighten the fixing screws
of the coupling after assembling the blade again. Always use sharp blades: the machine will be
subject to less strain and its working life will be longer. Clean the mower bar after every working
