Wing Gearbox Driveline Shield Access
1.
To remove shaft guard (#1) at the spindle gearbox,
use a flat head screw driver to unsnap latches (#2) on
both sides of guard (#1) and slide shaft guard over
driveline to expose driveline yoke. Do not unhook
safety chain (#3).
2. When servicing of driveline yoke is completed, return
shaft guard to its original position and secure with
latches (#2).
3. Check safety chain (#3). Make sure it is latched to
shaft guard mounting plate (#4) and shaft guard (#1).
Center Gearbox Driveline Shield Access
1.
To access the center driveline, push the latch release
button to open latch (#1).
2. Pull up on the splitter box shield (#2) and let it rest on
the center driveline shield (#3).
3. Pull up on the center driveline shield (#3) until it rests
in vertical position.
4. When servicing of driveline is completed, return
shielding to its original position.
5. Press down on the latch lever to engage latch (#1).
Latch should clamp shield tightly to the shield bracket

Drivelines
Before each use, check that all driveline shields and
drivelines are in place, undamaged and in working order.
Replace the shields and drivelines as needed.
DANGER
!
To avoid serious injury or death: Tractor power take-off shaft
shield, driveline shields, and gearbox shaft shields must be
installed and in good working condition to avoid driveline
entanglement and projectiles flying off of the driveline.
WARNING
!
To avoid serious injury or death: Do not operate a broken or
bent driveline. Such a driveline will break apart while rotating
at high speeds and can cause serious injury or death. Always
remove the implement from use until the damaged driveline
Drivelines With Slip Clutches
WARNING
!
To avoid serious injury or death:
•
Always shut tractor down using “Tractor Shutdown
Procedure” provided in this manual before dismounting
•
A slip clutch that has been in use or has slipped for as little
as only two or three seconds during run-in may be too hot
to touch. Allow a hot clutch to cool before working on it.
Friction clutches must be capable of slippage during
operation to protect gearboxes, drivelines, and other
drive train parts. Friction clutches should be “run-in” prior
to initial operation and after periods of inactivity to
remove any oxidation from the friction surfaces. Repeat
“run-in” at the beginning of each season and when
moisture seizes the inner friction plates.
