OPERATION
Detaching the Header (continued)
DANGER: Wait for all movement to
stop. A rotating driveline can cause
entanglement resulting in serious
personal injury or death.
8. Disconnect driveline from header shaft as
follows:
•
Pull back spring-loaded collar on driveline
yoke and remove yoke from header shaft.
•
Detach chain (if present) from header
hinged shield.
•
Pull back spring-loaded collar and store
driveline on pin welded to tractor frame at
(E).
9. Disconnect hydraulic hoses at quick couplers at
right and left-hand legs.
IMPORTANT: Where possible, connect hoses
to each other for storage except fore-aft as
noted below. Plug or cap all other couplers to
prevent hydraulic system contamination. Store
tractor reel drive hoses as shown at (G) to avoid
interference during hook-up.
WARNING: For headers with
hydraulic reel fore-aft, never connect
the header fore-aft couplers to each
other. This would complete the circuit
and allow the reel to creep forward in
transport, resulting in instability.
10. Disconnect electrical wiring harness.
NOTE: If a Hay Conditioner is installed, detach
supports between tractor frame and conditioner
forming shield.
11. Adjust length of center link to release load on
pins. Disconnect center link at header by
removing pin (C).
12. Slowly back tractor away from header. If hay
conditioner is attached, watch clearances at left
and right sides.
WARNING: Avoid driving the tractor
with header removed. Removing
header decreases the weight on
drive wheels, reducing steering
control. If necessary to drive tractor with
header removed, use transmission low speed
range, do not exceed half-maximum engine
speed and avoid loose gravel and slopes.
WARNING: Harvest Header with
Transport Option This windrower
tractor is not intended as a towing
vehicle for the Harvest Header
Transport configuration. If necessary to use
the tractor in this manner, add a minimum 2000
lb. (910 kg) counterweight on the lift linkage.
