PLOUGHS
The ploughs designed for the rotovator Grillo 12000 have been especially developed to obtain good ploughing
without over-straining the operator. The models available are a single-share plough and a 180° roll-over plough.
The latter is especially suitable when working backwards and forwards, such as along rows of vines or fruit-
trees. The depth of the furrow obtained may vary from 10 to 15 cm depending on the terrain.
The plough must be mounted on an adjustable implement-holder (see fig. 9) by simply removing the foot
support, pulling the split-pin and the pin (fig. 8). Then fit the implement-holder, replace the pin and secure
with the two side screws. It is also necessary to remove the two tiller assemblies by taking out the two
mounting screws, followed by the 5.00x10 tyred wheels.
ADJUSTABLE FURROWER
The adjustable furrower is an implement especially designed and manufactured for tracing furrows for
sowing or irrigation (fig.11).
The possibility of adjusting the position of the two wings enables furrow width to be regulated from
minimum of 10 cm to maximum of 30. Furrow depth can vary from 10 to 20 cm.
When working particularly hard ground, it is advisable to till before using the furrower. It is extremely easy
to mount; just remove the foot and fit a curved support, to which the furrower will be secured using a screw
clamp (fig. 11).
Remove the tillers and fit the wheels as described in for the ploughs.
IRRIGATION PUMP
The pump is fitted directly to the flanges of the rotovator top shaft (fig. 12) and secured by screwing 2 nuts
onto the stud-bolts. Since it does not have a release clutch, it must be fitted immediately before use and
removed immediately afterwards.
SPRAYER PUMP
The pump is fitted directly to the flanges of the rotovator top shaft (fig. 13) and secured by screwing 2 nuts
onto the stud-bolts.
RATCHET HUBS
Ratchet hubs are special wheel attachments, built to facilitate to the utmost the use of the rotovator with
a small trailer, since the ratchets act as differentials. The ratchets are fitted to the tiller shafts, locked with
the screws supplied, and then the tyred wheels are fitted (fig. 14).
TRAILER
The small trailer for the 12000 rotovator is a very useful accessory for light farm transport work (fig. 17).
Its main features are manoeuvrability, compactness and rapid attachment to the rotovator. The trailer is
fitted directly to the rotovator using the drawbar (fig. 18). Either the wheel extensions or the ratchet hubs
with tyred wheels 4.00x8 are also required. To fit, proceed as for the ratchet hubs.
N.B.: When re-mounting the tiller assemblies, it is essential also to fit the reverse gear safety
device nr.5 (fig. 1).
