A Chipper for Highway
Departments
The
Farmi CH 222 woodchipper is
designed for efficient and safe disposal of stems, branches and
bushes along roadsides. The chips can be blown into a truck or back
to the roadside.
The chipper is fed from the right side so the feed
is close to the material to be chipped. The
operator stands on the road, away from the
ditch and the traffic. The feed chute does not
stick outside the width of the tractor.
The tractor can therefore be driven safely on the
right side of the road without risk of the feed
chute hitting road signs or railings.
The aggressive power feed makes the
CH 222HF also the perfect machine for Christmas tree disposal.
A Chipper For Orchards
The
Farmi CH 222HF is easy to use
in orchards. It can be maneuvered between narrow rows as neither
the feed nor the discharge chutes stick out beyond the width of the
tractor.
Ease of Operation
The low feeding point ensures
effortless feeding of the chipper. The operator can stand with a
straight back. The discharge direction is adjustable 360 degrees.
The chipper stands up by itself on
the ground and is easy to hook up or remove from the tractor.
Power Requirements
Due to the inertia of the heavy and
large rotor, power units down to 35 HP can be used. About 7 HP is
required for every inch of round wood diameter. Thus, to chip a
5-inch round wood, you need a 35 HP tractor (7 X 5 = 35).
Hydraulic Feed
The hydraulic
feed is powered from the outlets on the tractor. The operator
can select feed, stop and reverse from the bar on top of the feed
chute. The turning speed of the rollers is continuously
adjustable from a knob on the hydraulic valve. The bottom feed
roller is fixed. The top roller is spring loaded. The
spring tension is adjustable. The material is squeezed between
the two rollers. The hydraulic feed chutes are close to the
ground so quite heavy trees can be manually fed into the chipper.
Minimum
oil requirement is 4 GPM;
maximum 18 GPM. The oil might heat up if the reservoir is small.
If the oil reservoir is under 10 gallons, the operator should check
for eventual overheating. An oil cooler should be installed on the
return line in case of overheating.
Safety Features
The Valby chippers do not have any
knife motion toward the operator-this reduces the risk of loose
material flying back through the feed chute.
The knives are counter-sunk into
the disk, so the stress of chipping is absorbed by the entire
backside of the knife, not just the knife bolts.
The discharge height is 7'11" above
ground so the discharge is above eye level. To accomplish safe
operation in various wind directions, the Valby chipper's discharge
direction is adjustable 360 degrees.
The deflector bonnet enables
placing the chips near or far. The Farmi chippers also have
several noise-reducing features. The discharge opening is above ear
level. It is adjustable and can be directed away from the
operator. The hydraulic feed rollers cover the feed opening, thus
reducing the noise level.
