Hitching and the Center
of Gravity


Pulling a load with the downward and
rearward force above the tractor’s
center of gravity will result
in a rear overturn.
Hitch only to the drawbar!
Hitching anywhere else can
lead to a rear overturn
and death!

Hitching Safely


If your foot slips from the clutch while
hitching to a machine, a helper could
be crushed!
If you have never used a particular
implement, ask for a demonstration
before you try the job.
Using 3-Point Hitch
Implements





Make sure you know how wide the implement is
compared to the tractor
Be sure the machine is in “transport” or “up”
position for travel on public roadways.
Lower the machine to the “field” position when you
are ready to use it.
Engage the machine operation mechanism (levers,
pins, etc) for the wheels to power the machine if
you are using a ground-driven machine. A qualified
operator should demonstrate this procedure for
each machine.
Begin field operation of the machine by paying
attention to field boundary fences and obstacles.
Using 3-Point Hitch
Implements (cont.)

Allow space at ends of rows or fields to left the equipment with
the 3-point hydraulic lift

Do not make turns with a 3-point hitch implement in or on the
ground


Backing a 3-point hitch implement while it is lowered onto the
ground can plug the seed drops of the planter. Lift the
implement before reversing the direction you are going to
prevent possible damage to the implement or 3-point hitch
draft and lift arms
Lift the implement to the transport position before using public
roads or passing through narrow farm gates. Ground driven
implements operated on roadways can damge the road surface
Making PTO Connections



PTO Speeds—designed to rotate at 540
rpm or 1,000 rpm. Dual speed PTO’s may
reach 630-1,170 rpm.
PTO Splines—by counting the number of
splines or teeth, the operator can identify
the speed of the PTO in rpm’s
PTO Sizes—PTO stub shaft diameter for
540 rpm shaft is 1 3/8 inch and the 1,000
rpm stub shaft with 21 teeth is 1 3/8 inch
PTO—Adult
Responsibilities




Be sure implement is in working order
Be sure that all safety features are in
place
Be sure the work area has no hazards
Be sure the youth has long hair tied
up out of the way, has non-skid shoes,
and snug-fitting clothes. Hearing
protection is recommended as well.
PTO Entanglements:




Generally involve the
operator 78% of the time
Occurred when shielding
was absent/damaged in
70% of the cases
Were at the PTO coupling,
either at the tractor or
implement connection nearly
70% of the time
Involved a bare shaft, spring
loaded push pin, or through
bolt component at the point
of contact nearly 63% of the
time




Occurred with stationary
equipment 50% of the
cases
Involved semi-stationary
equipment 28% of the
time
Happened mostly with
incidents involving nonmoving machinery at the
time of the incident
Occurred 4% of the time
when no equipment was
attached to the tractor
Precautions When Using
Hydraulics
For safe and correct operation,
remember these 3 points:
1. Clean Oil Needs
2. Heat Generated By Use
3. Oil Leaks Under Pressure

Connecting Hydraulic
Hoses to Couplers

Use the following steps:
– Use gloves or a wipe cloth to remove dirt
and grit from the couplers
– Remove the dust covers from the
couplers
– Push the couplers together until the lock
ring snaps the two parts securely.
Disconnecting Hydraulic
Hoses

Use the following steps:
– Relieve the static pressure
– Push back on the lock ring
– Remove the hydraulic hose
– Replace the dust caps on each connector
– Hang the hoses on the implement
– Keep hoses off the ground
Electrical Needs





Lights—added for nighttime operation,
repair work, and warning signals on public
roadway transport
Electrical Sensors—measure equipment
operation functions
Monitors—signal operator when machine
function is disrupted
Warning Devices—activated when reverse
gear sounds alarm. Horns and lights warn
bystanders of actions
Convenience Outlets—using wiring
harness, permit connection to trailer or
wagon for proper lighting on public roads
Using Electrical
Connections






Turn powered device to “off”
Wipe away moisture and dirt before
connecting
Lift protective cover to make connection
Align the prongs or plugs. Do not force
connections together
Grip connector body. Do not pull cord!
Consult Operator’s Manual for more info.
