  • Top frame beam is an impressive 6” X 6” in size.
  • The entire frame construction is fully welded, with welded-in back sheets.
  • The auger floor is 4mm thick and fully welded.
  • Frame is designed to handle the toughest harvest conditions.

Header Drive

  • PTO shaft(s) transfer shaft driven power to both the auger and knife drive(s).
  • Knife drive(s) are then driven with a heavy duty belt.
  • Auger is driven with a heavy #80 chain.


  • Before the crop engages the reel or cutterbar, it must first be divided by the header.
  • The 3020 header incorporates poly crop dividers that have a simple but very effective design.
  • The dividers gently present the most down and tangled crop to the reel and cutterbar while positively following ground terrain.

Divider Types

  • All 3020 headers are standard equipped with a medium length crop divider that is recommended for most crop conditions.
  • In tough conditions, such as tall and viney crops, an optional long crop divider is available.
  • Optional rod crop dividers are avialable.


Knife: Achieve Excellent Cut Quality

Reel Finger Timing

  • The guard and knife, along with the rest of the cutterbar, ensure that down and tangled crop is picked up and properly cut
  • The 3020 header comes standard with a 3-inch fine cut knife and guard
  • The 3 inch knife provides excellent cut quality while promote high cutting speeds


Knife Drive

  • Standard on all headers is a single heavy-duty high capacity wobble box knife drive
  • The knife drive is belt driven from the left side of the head
  • The 30 & 35 foot headers can be ordered with a dual knife drive
  • The dual knife drive is recommended in heavy crop or when cutting across rows


Skid Shoes

  • Reel positions sensors are located on both reel up/down and fore/aft
  • Just as important as the cutterbar suspension are the skid shoes that support the cutterbar
  • The 3020 header incorporates the same proven skid shoes used on the prior 1020 header
  • The short profile allows the shoes to follow constantly changing ground conditions
  • Since the pressure from the cutterbar is only spread over a small area on the skid shoes, it will prevent the header from “pushing” in soft or muddy conditions


Cutterbar: Superior TerraFlex Suspension System

TerraFlex™ Suspension System

  • One of the most impressive features of the 3020 header, setting it apart from other auger heads is the TerraFlex suspension system
  • Suspension design is the key to proper cutting in soft, muddy or hard field conditions
  • With fewer mo​ving parts and reduced friction the cutterbar is reliable and responsive
  • Provides flexible range of movement using a simple torsion block control
  • Cutterbar has 3 inches up and 3 inches down of travel


Rigid Cutterbar Mode

  • For cutting off the ground in crops such as wheat, the cutterbar can be locked rigid 
  • Cutterbar is locked rigid​ by moving a simple locking pin on each suspension arm
  • This versatility also you to have a flexible cutterbar for cutting on the ground and a rigid when cutting off


Manually Adjustable Cutterbar

  • Ground pressure is controlled and maintained by a fully adjustable Case IH TerraFlex torsion block
  • Located between the main frame and the support arm
  • Adjusted by manual adjustment screws on the back side of the header


In-cab Cutterbar Adjustment

  • Rather than having to actually stop the combine, get out, and manually adjust each bolt individually, the operator is able to chan​ge the down pressure on the cutterbar instantly from the comfort of the cab
  • Adjustments are easily made from the cab while harvesting to accommodate ever-changing ground conditions


Auger: Smooth, Easy Feeding


  • To promote grain quality and smooth, consistent crop feeding, the 3020 header uses a large 26-inch diameter auger
  • Auger features 5-inch deep flighting to gently convey the crop from the cutterbar to the feeder


Auger Floor

  • All 3020 Heads include as standard equipment a stainless steel auger floor for smooth, easy feeding
  • The transition from the cutterbar to the auger floor provides an easy flow of crop over the front floor dam into the auger trough


Auger Floor

  • All 3020 Heads include as standard equipment a stainless steel auger floor for smooth, easy feeding
  • The transition from the cutterbar to the auger floor provides an easy flow of crop over the front floor dam into the auger trough


Auger Adjustment

  • The 3020 header promotes crop and header adaptability with a fully adjustable auger
  • To fit the customer’s harvest needs, the auger can be adjusted both vertically and horizontally


Pick-up Reel

Six Bat Reel

  • The Case IH 3020 six bat reel positively engages the crop, and then gently lifts the crop over the cutterbar to the auger
  • Reel design and gentle crop engagement is imperative to ensure proper feeding and cutting
  • The reel design promotes increased grain savings and grain quality with gentle crop handling​


Reel Options

  • There are two tine options available for the 3020 header
  • Plastic reel tines are recommended for most crop types and conditions
  • For more demanding conditions, such as rice and tough down crop, steel tines are available


Reel Position Sensors

  • Reel positions sensors are located on both reel up/down and fore/aft
  • When a new header height is set the reel will be programmed to the set height as well
  • Allows for a short bean and a tall bean setting for the reel
  • Proper reel position increases grain savings, combine productivity and reduces operator fatigue


Reel Finger Timing

  • The reel finger timing is adjustable on all 3020 headers
  • Timing is adjustable with a simple lever and wrench
  • This provides the customer the ability to tailor reel feeding based on crop types and conditions
