GENERAL DESCRIPTION AND INTENDED
USE OF THE CHIPPER
FARMI CH27 is a disk chipper for tractor-
mounted operation. As the chip size is adjustab-
le, the chipper can be used e.g. for the producti-
on of chips to be used for landscaping or for bio
energy. The chipper can be used to chop trunks,
twigs and tree tops as well as chopping waste
and saw mill waste. The chipper can shred wood
with a max. trunk diameter of 250 mm.
The FARMI CH27 chipper is mounted to the
3-point hitch of a tractor. It is driven by the trac-
tor PTO. The driving force is transferred to the
chipper via the PTO drive shaft. During chip-
ping, the chipper rotor on which the blades for
cutting the material are mounted is driven by
the tractor. From the knives, the chips are fed to
the additional knives which cut the chips to the
desired size. Finally, the chips are discharged to
the desired position using a discharge pipe. The
material to be chipped is fed into the chipper
manually.
The FARMI CH27 chipper must always be used
together with one of the following Farmi feed
units:
Chipper/feeder device combination for manual
feeding:
FARMI CH27 + DMR
Chipper and feed unit combinations for grab
loader feed:
FARMI CH27 + ACR
FARMI CH27 + ACC
FARMI CH27 + ACR + BC3000
The FARMI CH27 chipper
must never be coupled to
other feed units. Moreover,
the chipper must not be
used without a feed unit.
CAUTION!

DESCRIPTION OF WORKSITES
A worksite with a level and rm surface should
be used when chipping. Clear any small brush
and stones from the worksite.The material to be
chipped should be as clean as possible - make
every eort to keep soil or stones from entering
the chipper.
Avoid chipping in close proximity to power
lines. The distance from power lines must
always be at least 5 metres.
Reserve an adequate amount of working space
for the chipper and transport equipment.
Do not store fuelwood stacks near objects
which can cause damage to the chipper if they
should enter it (e.g. saws, log tongs, etc.).
If the chips are to be discharged directly into
chip storage, ensure that the discharge hole is
set at a suitable height.
