SPC 20 OPERATOR’S MANUAL
OPERATION C-9
9. Header Speed:
Header speed is the speed of the rotating knives, gathering belts, snapping rollers, drag chains,
and/or reel speed. Header speed must be set to match, or slightly slower that the ground speed.
Header speed is controlled by a Racine valve, which diverts hydraulic oil from the threshing cylinder
drive. When adjusting the header speed it is necessary to adjust the threshing cylinder rpm to
compensate for hydraulic flow adjustment. Review
HEADER SETTINGS AND ADJUSTMENTS for
individual header details.
10. Header Lift:
Header lift lever raises the head to avoid rocks, holes, and other obstacles. When clear of obstacles
the header height lever should be pushed forward to allow the head to ride on the header gauge
wheels. It is important to lift the head whenever turning around or at road speed. Review Header
Settings and Adjustments for individual header information.
11. Reel Lift (Optional)
Pull back on this lever to raise the reel. Review
HEADER SETTINGS AND ADJUSTMENTS for
proper reel position. Push forward on lever to return reel to preset gauge arms.
11. Folding Unload Auger (Optional):
This lever controls a hydraulic cylinder, which controls the top portion of the folding unload auger.
Push forward and hold the lever to actuate the cylinder until the auger is in the unload position. Pull
back on the lever to lower the auger to legal transport height.
12. Reverse Foot Pedal:
Returns forward reverse lever to neutral position.
13. Forward Foot Pedal:
When the speed control lever is set the forward foot control can be used to quickly move the
machine up to harvesting speed, allowing the operator's hands to be free for other operations.
Depress foot pedals slowly and consistently to avoid machine bucking and jerking.
14. Cylinder / Concave Clearance Adjuster:
Cylinder / Concave Clearance is a critical aspect to produce proper threshing action without suffering
seed damage. Rotate the adjuster clockwise to increase clearance and counter clockwise to
decrease clearance. Tighten set bolt to lock concave in position.
15. Fuel Gauge:
Displays fuel level. Add diesel fuel only.
16. Voltmeter:
Displays voltage supplied by the main power alternator. The voltmeter should read between 13.5 -
14.5V at full engine rpm. Check this gauge if electronics act sluggish, or if there are electronics
problems in general. If voltage drops or rises outside of the 13 - 15V range diagnose the problem,
check
