SPC 20 OPERATOR’S MANUAL
C-6 OPERATION
OPERATOR CONTROL FUNCTIONS
A combine has four distinct operations: feeding, threshing, separating, and cleaning. These
operations are interrelated to produce a good overall harvesting result. Because of these
relationships, the proper adjustment to fix a problem may not be obvious. What appears to be a
cleaning problem could actually be caused by feeding the machine too fast (a feeding problem).
Making adjustments quickly and correctly will allow efficient harvesting. Use this section to
familiarize yourself with the controls and the effects it will have on the machine. Use the
TROUBLESHOOTING SECTION to determine possible causes for harvesting difficulties and
probable solutions. All intended operators must be familiar with the functions of the machine for
operator safety and proper harvesting results.
