OPERATION
HEADER LOCK
WARNING: To avoid bodily injury or
death from fall of raised machine,
always engage header lock (A)
before going under windrower for any reason.
NOTE: Should the condition arise where the lock
pin cannot be installed with the header fully raised,
install shim washers between bracket (B) and stop
(C).
When not in use, store pin at (D).
CUTTING HEIGHT
IMPORTANT: Avoid raising header to full height
when in field position. Right wheel may rotate into
transport position.
The windrow should normally be laid on stubble
from 6 to 8 inches high (150 to 200 mm).
Benefits of a stubble of this height:
• Allows free circulation of air under the windrow
for more even drying.
• Supports the windrow without bending.
• Keeps grain heads from contacting ground.
Heads that touch the ground are difficult to pick
up and will sprout in damp weather.
Cutting height is controlled from the tractor with
remote cylinder control valve lever.
Minimum Header Height
The header lift cylinder has an adjustable stop to
vary minimum header height. To adjust:
1.
WARNING: To avoid bodily injury or
death, raise header fully and engage
header lock.
2. Turn stop (E) towards cylinder barrel to raise
minimum height.
