GENERAL SAFETY
The following are general farm
safety precautions that should be
part of your operating procedure for
all types of machinery.
1. Protect yourself.
When assembling, operating and servicing
machinery wear all the protective clothing
and personal safety devices that COULD be
necessary for the job at hand. Don't take
chances.
You may need:
· a hard hat.
· protective shoes with slip resistant soles.
· protective glasses or goggles.
· heavy gloves.
· wet weather gear.
· respirator or filter mask.
· hearing protection. Be aware that prolonged
exposure to loud noise can cause
impairment or loss of hearing. Wearing a
suitable hearing protective device such as
earmuffs (A) or earplugs (B) protects
against objectionable or loud noises.
2. Provide a first-aid kit for use in case of
emergencies.
3. Keep a fire extinguisher on the machine. Be
sure the extinguisher is properly maintained
and be familiar with its proper use.
4. Keep young children away from machinery
at all times.

GENERAL SAFETY
6. Wear close-fitting clothing and cover long
hair. Never wear dangling items such as
scarves or bracelets.
7. Keep hands, feet, clothing and hair away
from moving parts. Never attempt to clear
obstructions or objects from a machine
while the engine is running.
8. Keep all shields in place. Never alter or
remove safety equipment. Make sure
driveline guards can rotate independently of
the shaft and can telescope freely.
9. Use only service and repair parts made or
approved by the equipment manufacturer.
Substituted parts may not meet strength,
design, or safety requirements.
10. Do not modify the machine. Unauthorized
modifications may impair the function
and/or safety and affect machine life.
11. Stop engine and remove key from ignition
before leaving operator's seat for any
reason. A child or even a pet could engage
an idling machine.
12. Keep the area used for servicing machinery
clean and dry. Wet or oily floors are
slippery. Wet spots can be dangerous when
working with electrical equipment. Be sure
all electrical outlets and tools are properly
grounded.
13. Use adequate light for the job at hand.
14. Keep machinery clean. Straw and chaff on a
hot engine are a fire hazard. Do not allow oil
or grease to accumulate on service
platforms, ladders or controls. Clean
machines before storage.
15. Never use gasoline, naphtha or any volatile
material for cleaning purposes. These
materials may be toxic and/or flammable.
16. When storing machinery, cover sharp or
extending components to prevent injury

OPERATING VARIABLES
Satisfactory function of the header and hay
conditioner in all situations requires making proper
adjustments to suit various crops and conditions.
Correct operation reduces crop loss and allows
cutting of more acres. As well, proper adjustments
and timely maintenance will increase the length of
service you receive from the machine.
The variables listed here and detailed on the
following pages will affect the performance of the
header and conditioner. You will quickly become
adept at adjusting the machine to give you the
desired results.
LEAN BAR POSITION
IMPORTANT: To prevent structural damage to
header, do not operate with lean bar removed.
Use the lean bar adjustment to accommodate
different crop heights.
The lean bar should strike the upper portion of
crop, leaning it away from the header and
exposing the stalks to the sickle.
To raise or lower lean bar, re-position hardware
(A) in adjustment holes as required.
NOTE: In very tall crops, to prevent pinning of crop
around lean bar, extensions are available. See

OPERATION
REEL SPEED
For best feeding of crop into the sickle and auger,
reel speed should be just faster than ground
speed. This gently sweeps crop across sickle into
auger. Excessive reel speed causes undue wear
of reel components and unnecessary load on reel
drive, resulting in uneven reel motion.
922 and 933 Headers
See Windrower Tractor Operator's Manual for
identification and instructions for use of reel speed
control in cab.
NOTE: Both speed control knobs on tractor
console are used to adjust reel speed.
912 Header
