  • Page 31: Combine Function

    SPC 20 OPERATOR’S MANUAL COMBINE FUNCTION DESCRIPTION The threshing operation is accomplished by a hydraulically driven, 15-1/4” diameter, variable speed rasp bar cylinder and one adjustable, underslung, grated style concave. A strawpuller positioned directly behind the threshing cylinder prevents cylinder wrapping and assists the movement of plant material through the machine.

  • Page 34 SPC 20 OPERATOR’S MANUAL 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).

  • Page 39 SPC 20 OPERATOR’S MANUAL Cylinder / Concave Clearance - Cylinder / Concave Clearance is another critical aspect to produce proper threshing action without suffering seed damage. Examine the discharge at the rear of the machine reduce clearance if there is still seed on the plant, which may require the ground speed and header speed to be reduced.

The size of the ears, stalks, and amount of trash taken in will determine spacing. Set taper by moving adjustable plate until the clearance between two plates is 1-7/16”...
  • Page 42 SPC 20 OPERATOR’S MANUAL Header Height Header height is a matter of preference and is dependent on the condition of the crop. In standing corn the header only needs to be run slightly below the ears. When harvesting fallen stalks lower the head, so that the snout lifts the stalks before they enter the rollers.
  • Page 43 SPC 20 OPERATOR’S MANUAL STANDARD PLATFORM HEAD Cutting Bar Height Set cutting bar so that the sickle cuts below all the seed, but does not necessarily cut all the plant. When the header height is lowered use extra caution to avoid rocks and other obstructions. Gauge wheels are used to set the minimum ground clearance.
