of the main concerns in designing and
developing equipment. However, every year
many accidents occur which could have been
avoided by a few seconds of thought and a
more careful approach to handling equipment.
You, the operator, can avoid many accidents
by observing the following precautions in this
section. To avoid personal injury or death,
study the following precautions and insist
those working with you, or for you to follow
them.
2. In order to provide a better view, certain
photographs or illustrations in this manual
may show an assembly with a safety shield
removed. However, equipment should never
be used in this condition. Keep all shields in
place. If shield removal becomes necessary
for repairs, replace the shield prior to use.
3. Replace any safety sign or instruction sign
that is not readable or is missing. Location of
such safety signs is indicated in this manual.

children be allowed to work with this
equipment. Do not allow persons to use or
assemble this unit until they have read this
manual and have developed a thorough
understanding of the safety precautions
and of how it works. Review the safety
instructions with all users annually.
6. This equipment is dangerous to children and
persons unfamiliar with its operation. The
operator should be a responsible, properly
trained and physically able person familiar
with machinery and trained in this equipment's
operations. If the elderly are assisting with
work, their physical limitations need to be
recognized and accommodated.
7. Never exceed the limits of a piece of
machinery. If its ability to do a job, or to do so
safely, is in question - DON'T TRY IT.
8. Do not modify the equipment in any way. Un-
authorized modification may result in serious
injury or death and may impair the function
and life of the equipment.
9. In addition to the design and configuration of
this implement, including Safety Signs and

2.3 SAFETY TRAINING
1. Safety is a primary concern in the design and
manufacture of our products. Unfortunately,
our efforts to provide safe equipment can
be wiped out by a single careless act of an
operator or bystander.
2. In addition to the design and configuration of
equipment, hazard control and accident
prevention are dependent upon the
awareness, concern, prudence and proper
training of personnel involved in the operation,
transport, maintenance and storage of this
equipment.
3. It has been said, "The best
safety feature is an
informed, careful operator."
We ask you to be that
kind of an operator. It is the
operator's responsibility to read and under-
stand ALL Safety and Using instructions in the
manual and to follow these. Accidents can be
avoided.
4. Working with unfamiliar equipment can
lead to careless injuries. Read this manual
before assembly or using, to acquaint
yourself with the machine. If this machine
is used by any person other than yourself,
or is loaned or rented, it is the machine
owner's responsibility to make certain that
the operator, prior to using:
a. Reads and understands the operator's
manuals.
b. Is instructed in safe and proper use.
5. Know your controls and how to stop tractor
and machine quickly in an emergency. Read
this manual and the one provided with tractor.
6. Train all new personnel and review
instructions frequently with existing workers.
Be certain only a properly trained and
physically able person will use the machinery.
A person who has not read and understood all
using and safety instructions is not qualified to
use the machine. An untrained operator
exposes himself and bystanders to possible
serious in- jury or death. If the elderly are
assisting with the work, their physical
limitations need to be recognized and
accommodated.
2.4 SAFETY SIGNS
1. Keep safety signs clean and legible at all
times.
2. Replace safety signs that are missing or have
become illegible.

clothing or jewellery to be around equipment.
3. PROLONGED EXPOSURE
TO LOUD NOISE MAY
CAUSE PERMANENT
HEARING LOSS!
Power equipment with or
without equipment attached
can often be noisy enough
to cause permanent, partial
hearing loss. We recommend that you wear
hearing protection on a full-time basis if the
noise in the Operator's position exceeds 80db.
Noise over 85db on a long-term basis can
cause severe hearing loss. Noise over 90db
adjacent to the Operator over a long-term ba-
sis may cause permanent, total hearing loss.
NOTE: Hearing loss from loud noise (from
tractors, chain saws, radios, and other such
sources close to the ear) is cumulative over a
lifetime without hope of natural recovery.
4. Clear working area of stones, branches or
hidden obstacles that might be hooked or
snagged, causing injury or damage.

The Farmer-Helper 3
Point Hitch Wood
Chipper is a rotor with
blades for chip- ping
wood. A hinged feed
hopper moves the wood
material into the rotor.
Each rotor is designed with
4 blades and a twig-break-
er to generate the small
pieces of wood. A station-
ary knife at the rear of the
rotor housing is placed by
the moving knives to shear,
chip or chop the material.
The tractor provides
rotational power
through a PTO shaft on
the front
of the frame and hydraulic
power for the hydraulic
feed hopper.

Revision 1-2016
5. 5 DRIVELINE DIMENSION
A PTO driveline is supplied with the machine. To ac-
company the variety of 3 point hitch geometry available
today, the driveline can be too long for most machines
or too short for others. It is very important that the drive-
line be free to telescope but not to bottom out when
going through its working range. If the driveline bottoms
out, the bearings on both the machine and tractor PTO
shaft will be overloaded and fail in a short time.
1. To determine the proper length of the driveline,
follow this procedure:
a. Clear the area of bystanders, especially small
children.
b. Attach the chipper to the tractor (see section
5.8) but do not attach the driveline.
Fig. 11 DRIVELINE DIMENSIONS
c. Raise the machine until the input shaft is level with
the tractor PTO shaft.
d. Measure the dimension between the locking
grooves on the tractor PTO shaft and the machine
input shaft.
e. Measure the same dimensions on the compressed
driveline.
f. If the compressed driveline dimension exceeds the
machine dimension, the driveline will have to be cut.
2. When cutting the driveline, follow this procedure:
a. Subtract the machine dimension (A) from the uncut
driveline dimension (B) or (B-A). This dimension
determines how much too long the driveline is.
b. Add another inch (25 mm) to the dimension
to be sure it doesn't bottom out, to determine
(C) the cut off dimension.
c. Use a hacksaw to cut dimension (C) from
