5 TROUBLESHOOTING GUIDE
The Troubleshooting Guide, shown below, is included to help you quickly locate problems that can hap-
pen using your SF4800 Soil Finisher. Follow all safety precautions stated in the previous when making any
adjustments to your machine.
PROBLEM PROBABLE CAUSE:SOLUTION
1. FIELD NOT LEVEL BEHIND SOIL FINISHER A. WING NOT LEVEL WITH MAIN FRAME:
Adjust depth control on wing lift cylinders so that
wings operate at same depth as frame.
Lift cylinders out of phase. Raise Soil Finisher and
hold hydraulic lever until all lift cylinders are com-
pletely extended.
Extend wing fold cylinders to allow wings to flex over
uneven ground.
B. SOIL FINISHER NOT LEVEL FRONT TO BACK:
Adjust radius rod to level unit.
Thread nut completely onto leveling rod and lock with
jam nut.
C. DISCS RUNNING TOO DEEP: Adjust discs only
deep enough to cut residue and level ridges.
D. HARROW NOT SET CORRECTLY:
COIL TINE HARROW - Adjust harrow teeth at more
aggressive angle and/or increase spring pressure.
SPIKE TOOTH DRAG HARROW - Adjust harrow up
or down until harrow runs flat.
SPIKE TOOTH SPRING HARROW - Adjust angle of
teeth for more aggressive action and/or increase
spring pressure.
E. UNIT DOES NOT STAY LEVEL WHEN DISCS
ARE RAISED OR LOWERED: Install optional hydrau-
lic radius rod. See your dealer for details.
2. DISC GANG STOPS TURNING AND PLUGS. A. DISCS SET TOO SHALLOW: Increase depth of
disc gangs. Disc should run deep enough to cut resi-
due.
B. SCRAPERS SET TOO TIGHT: Adjust scrapers for
less spring pressure. Scrapers should apply only
enough pressure to clean damp soil from discs.
C. DISC BLADE WEAR: Disc may be too small. New
blades measure 20".
D. DISC BLADE CONCAVITY: Disc blades should
have 1-5/16" of concavity.
