Figure 4.157: Safety Prop Lever
5. Disengage the safety props on both lift cylinders as follows:
a. Turn lever (A) away from the header to raise the safety
prop until the lever locks into the vertical position.
b. Repeat the previous step for the opposite cylinder.
NOTE:
If the safety prop will NOT disengage, raise the header to
release the prop.
6. Start the engine.
7. Lower the header fully.
8. Shut down the engine, and remove the key from
the ignition.
4.6.2 Header Float
The windrower is equipped with float springs that are fully adjustable with hydraulic cylinders. Spring tension is adjustable
from zero to maximum tension through the Harvest Performance Tracker (HPT). The header float feature allows the header
to follow the contours of the ground closely as the windrower moves forward. The header is able to respond to sudden
changes in elevation or obstacles quickly. The float setting is ideal when the cutterbar rides along the ground with minimal
bouncing, and without scooping or pushing soil.
IMPORTANT:
•
Configure the header float setting to be as light as possible, while limiting the amount of bouncing produced by the
header. Doing so will reduce the amount of wear placed on knife components, and will prevent the header from
scooping soil.
•
Prevent the header from bouncing excessively by operating at a slower ground speed when the float setting is light. A
bouncing header results in raggedly cut crop.
•
Before setting the header float, install all of the header kits (for example: upper cross auger; skid shoes; slow speed
transport kit). If the Slow Speed Transport (SST) tow-bar will be stored on the header during operation, set the float
with the tow bar in place.
•
Adjust the float when adding or removing optional attachments which change the weight of the header.
Checking Float
Check the header float setting by measuring the force required to lift the header.
DANGER
To prevent bodily injury or death from the unexpected startup of the machine, always stop the engine and remove the
key from the ignition before leaving the operator
’
s seat for any reason.
DANGER
Never start or move the machine until you are sure that all bystanders have cleared the area.
