FURROWER BEHIND THE ROTARY TILLER
This furrower has to be mounted behind the rotary tiller and it works together with the tiller. It is
used to carry out irrigation and planting furrows (fig. 18).
ADJUSTABLE FURROWER
This implement has been specially designed for sowing and irrigation furrowing. It can be directly
attached to the flange of the machine situated in the rear part of the gearbox, in place of the rotary
tiller. The position of the two wings can be changed to vary the furrow width from a minimum of 10
cm (4") to a maximum of 30 cm (11.8"). Depth ranges from 10 cm (4") to 20 cm (8"). In case of
particularly hard soils till well before furrowing. The results obtainable can be improved by
attaching the tires 6.5/80-12 with widened disks or with wheel enlargements (fig. 18A).
TOWED TRAILER
A very useful implement for small farming hauls. Its handiness, small size and quick applicability to
the walking tractor are its most outstanding features. The trailer can be attached directly to the
walking tractor leaving the rotary tiller on and connecting it by the specific towing bar (fig. 21). Max.
Load capacity 400 kg on a plan surface. Do not use the trailer on slopes higher than 5%.
Passengers are not allowed. The trailer cannot be used on public roads.
CUTTER BAR
The cutter bar that can be attached to the walking tractor 131 has a central control (fig. 19). Its
toughness and high performance make it the best piece of equipment for mowing quite large areas
instead of a motor mower which would remain unused for a long time, while the walking tractor can
be used with many other implements. The cutter bar must be attached to the frame for attachments
of the walking tractor in place of the rotary tiller. The handle must be turned by 180°, setting it on
the engine side. Before turning the handle the four control rods must be removed from their
supports. Once the handle has been turned the two rods and the gearbox lever, furnished with the
cutter bar itself, must be fixed (see the instruction on the spare parts booklet). The most suitable
speed for mowing is R2, that is "fast reverse".
Maintenance
The motor mower 131 does not require special maintenance. However, to keep it at its best
performance it is advisable to effect the following operations:
– Check that all screws and nuts are tightened; particularly the nuts fixing the cutter bar to the
machine.
– Sharpen the blade frequently; to do this it is necessary to slip off the blade from the bar,
removing first the blade coupling (fig. 20) which is fixed by two screws. Sharpen the blade with the
special grindstone, then fix it on again making sure to tighten the two fixing screws of the blade
coupling.
– Check the blade pressers frequently (fig. 20). They must be neither too tight to block the blade,
nor too loose to allow too much clearance.
Warning: when the rotary tiller is put back in place do not forget to re-activate the safety device no.

TWO STAGE SNOW THROWER
This implement has been especially designed for the 131 and it is very useful for clearing snow
from squares, access roads and garage entries. It consists of a turbine rotary unit enclosed in a
special case open on the front, which turning at high rotation speed, collects snow and then throws
it through a pipe whose inclination can be adjusted as desired. Snow can thus be thrown 10-12
mts away (33'-40') in any desired direction. The snow thrower is 80 cm (31.52") wide and can clear
off snow up to 40 cms (16") high. Wheel-weights should be used for a better grip on the ground. If
the snow is very wet, keep the discharge pipe pointing straight forward to avoid obstructions at the
outlet.The snow thrower is attachable to the flange for implements with the handles turned by 180°
