SNOW THROWER
This implement (fig. 14) has been especially designed for this particular rotovator. It is very useful
for clearing snow from yards, driveways, etc. It consists of a turbine rotary unit enclosed in a
special case open at the front, which rotates at high speed, collecting the snow and throwing it
along a pipe. The pipe angle can be adjusted to throw the snow in any direction to a distance of 8 -
10 metres.
The snow thrower is fixed to the implement flange using two nuts. The handlebar must be turned
through 180° towards the engine; for this operation follow the directions given for the mower bar.
To operate the snow thrower, the safety device preventing simultaneous engagement of reverse
gear and the P.T.O. (necessary with the rotary tiller), must be disconnected by removing the allen
screw on the PTO lever.
Important: when reconnecting the rotary tiller, the safety device must be set in the original
position. We do not accept any responsibility for failure to follow this rule.
The snow thrower is 70 cm wide and can clear snow up to 40 cm deep. Wheel weights should be
used for best performance. If the snow is very wet, keep the ejection pipe turned forward to avoid
obstructions at the outlet. The two side skids must be adjusted so that they just skim level ground
(asphalted streets) or keep the snow thrower high if the ground is uneven.
Maintenance: when work is over, remove any snow left in the snow thrower so it cannot freeze
and block the turbine. Do not clean the attachment when the engine is running. Attention,
danger! Do not touch the snow thrower while it is working.
ATTENTION!
While attaching the different implements to the flange, make sure that the two parts are perfectly
aligned. The nuts of the two stud-bolts must be screwed on by hand and then using a wrench so
that they apply pressure to the flange simultaneously.
PLOUGHS
The ploughs designed for this rotavator have been especially developed to obtain good ploughing
without overstraining 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. Users can
achieve excellent performances using the tyres 5.00-12 and possibly the wheel-weights, which
improve machine's adhesion.
ROTARY CUTTER
The rotary blade cutter 75cm for the rotovator (fig. 16) is designed for the maintenance of grounds
with too high grass. The high power available, the driving wheels, the working speeds and the
reverse gear allow operation in the most difficult conditions without tiring the operator and with
considerable time saving. The rotary cutter is fixed to the implement flange using two nuts. It is
supplied with the lateral rams for hard conditions, or with front support wheels in order to use it with
low grass and levelled soils. The handlebar must be turned through 180°towards the engine; for
this operation follow the directions given for the mower bar. The blade is driven by means of a
bevel gear pair and is equipped with a release mechanism and a brake blade so that its force of
inertia cannot drag the machine forward when the clutch is engaged. To adjust the cutting height
vary the position of the rotary cutter wheel, or of the lateral rams. A version with grass bin is also
available.
Maintenance: Keep the lawn mower blade well sharpened: the cut will be better and the engine
will not strain. Always tighten the two fixing bolts well when fastening or removing the blade. Check
the two nuts fixing the awn mower to the machine frequently.
Check the gearbox oil level every 50 hours, removing the cap on the top, and make sure that the
oil level is within 50mms of the hole; if the level is lower add 80W/90 (API GL5 US-MIL-L-2105D)
gearbox oil. Change the oil once a year. Attention! Rotating blades are very dangerous, never
