| Today’s corn hybrids are taller, dryer and more brittle at harvest time. |
| Maximizing Trash Reduction in three easy steps with CALMER's TRASH REDUCTION KITS |
| “I farm in Texas and at harvest time, the corn is 15% and the air temperature is around 100 degrees so conditions are extremely dry. We put Calmer’s smaller- tooth sprockets on one-half of my 843 corn head and I could visually see Calmer’s side had a lot less stalks coming in by the time I had traveled 500-feet. We then converted the rest of the corn head to Calmer’s smaller- tooth sprockets and have had no problems.” |
| Lawrence Friesenhahn, Knippa, Texas |
| “I am really pleased with Calmer’s Trash Reduction Row-Unit Upgrade Kit. The kit took care of every problem we had. We installed Calmer’s Trash Reduction Row-Unit Upgrade Kit last season and it was the first season we had without stopping once to remove trash from the corn head. We wish we had installed it years ago.” |

| I am glad you've come to this portion of my web site. In case you are not aware of it, I am the farmer that invented the 15" corn head in 1995. Since that time we have been testing both red and green corn heads throughout the United States. What you are about to read is my train of thought on reducing trash intake at the corn head, which ultimately increases ground speed, reduces horsepower and fuel consumption and reduces grain loss. |
| Step 1 Install CALMER™ 6-Tooth Gathering Chain Drive Sprockets The Problem - Stalk Breakage |
| With genetic enhancements, today’s corn hybrids are taller and dryer and therefore more brittle at harvest time. Current corn heads utilize row units with speed ratios from the 1960’s that used fast gathering chain speeds. Using these fast gathering chain speeds to harvest tall brittle corn plants, causes the gathering chain lug to break off the top half of the plant before the stalk rolls have a chance to pull all of it below the stripper plates. The gathering chain lug then takes the broken portion of the plant and pushes it into the cross auger. When the cross auger conveys these broken portions of the corn plant to the center of the corn head, they collide and create a LARGE PILE OF FLUFF (see photo below right). The Evidence The first indication that the gathering chain was running too fast was confirmed during kill stops. Examinations of the large pile of fluff indicated it was composed mostly of the top portion of the corn plant broken off by the gathering chain lug. |
| The second indication that the gathering chain was running too fast was corn stalks hair pinning at the top of the stripping tunnel on a wet or damp day. This happens because the gathering chain lug forces the top portion of the corn plant over the row unit frame. The third indication that the gathering chain was running too fast was confirmed while harvesting down corn. We have noticed root balls being pulled out of the ground and dragged into the corn head because the gathering chain speed is faster than the ground speed. The Solution – Slowing Down the Gathering Chain |
| “The smaller sprocket slowed the gathering chain down and that helped – quite a bit with the trash reduction.” |
| Steve Hardy Walnut, IL |
| In multiple kill stops on a dry afternoon, the smaller sprockets reduced trash intake and stalk breakage by as much as 78-percent in SW Texas. Harvesting speeds increased by as much as 3 mph. |

| “I've been using Calmer's Trash Reduction Row-Unit Upgrade Kit system for years. It definitely reduces trash. No reason for gathering chain to go zing'in around at high speeds.” |
| Allen Berry, farmer/crop consultant - Nauvoo, Illinois - (217) 357-5362 Switched to 15-inch rows in 1996 Total acres - 1,400 |
| Too much flute overlap. |
| The Evidence These overlapping flutes spin at 800 RPM’s creating a wall of rotating steel restricting entry of the corn stalk. By examining used straight fluted rolls and straight fluted knife rolls, the first 2-inches of the flutes are worn out. The balance of the flutes indicates minimal wear. Stripper plate wear also confirms this theory. |
| Beaters rotating at high speed. Straw cannot engage with beaters |
| THE FOUR MODES OF ACTION |
| Receiving |
| In this mode the 1” window appears. This allows the base of the corn stalk to flow easily from the helical screw area into the knife chambers. |
| CALMER™ Beveled Stripper Plates are longer (A), have a straight edge (B), and a beveled edge (C). |
| CALMER™ Beveled Stripper Plates are designed to match the natural shape of the bottom side of the corn leaf and the butt of the ear and ear shank. This significantly reduces leaf and husk intake |

We wish we had installed it years ago.” |
| Gathering Chain Lug Timing: Standing Corn – Stagger Lugs for less aggressive gathering to reduce trash intake. Down Corn – Synchronize lugs to be horizontally opposed for more aggressive gathering and slow corn head speed down. Cross auger should be vertically adjusted to have a 1 ¾” clearance between auger flighting and tray. (See photo left.) This significantly reduces ear slicing which is a cause of cracked kernels in the grain tank and increases traction on trash. (You may need to increase the length of the slots in the end plate bearing hanger to allow for this adjustment.) Cross auger should be horizontally adjusted as close to the feeder house chain and rear stripper as possible, this will improve the transfer of material from cross auger to the feeder house chain thus reducing ear toss. |
| Feeder House Chains should be adjusted as close as possible to the cross auger, this also helps reduce ear toss. Sometimes we add a half link to extend the feeder chain length. Plastic Gathering Chain Paddles: Attached to the gathering chain lugs will improve gathering and conveying performance in down corn. Some reports also indicate improved performance in trashy conditions. Corn Head Angle should be between 23 and 25-degrees for optimum performance in both standing and lodged corn. Put the combine on a level surface then lower the corn head until the row unit frame is 2-inches off the ground. Then place a magnetic protractor on the stripper plate and read the angle. If the angle is too steep, pull the top of the corn head toward the combine or push the bottom out or a combination of both. Gathering Chain Tighteners occasionally lock up. This is caused when the spring vibrates and augers itself into the hole between the bolt and the flat strap. This can be fixed by adding a second washer at the bottom of the pipe spacer identical to the washer that is currently at the top of the pipe spacer. Apply Never Seize or lubricate the bolt threads for future adjustment. Opening Stripper Plates can reduce trash intake, but can also increase header loss. Normal settings are 1 1/4-inch bottom and 1 5/16-inch top. Case IH cross augers have 4-inches of flighting overlap in the center. JD Cross Augers have none. We believe that 4-inches of overlap increases traction and helps pull lose trash and fluff under the auger and into the feederhouse. A small section of flighting can easily be welded onto the cross auger flighting to create this overlap. Use reverse flighting on 30-foot split cross augers. In the past, split cross augers had no reverse flighting near the bearing hanger. Some older 12-row, 30-inch corn heads used rubber flaps and no flighting. The performance of those augers was poor. New replacement augers with reverse flighting can be purchased from John Deere (right-hand part #AH208489, LH part #AH208488). See photo left. |

EXPERIENCE THE DIFFERENCE...
| To slow down JUST the gathering chain, we installed the CALMER™ 6-tooth gathering chain sprocket. This sprocket is 25-percent smaller than the factory 8-tooth sprocket allowing the stalk rolls to make additional revolutions, making more of the plant disappear below the stripper plate before the gathering chain lug can break it off. We suggest that you continue to run the rest of the corn head at its normal operating speed. Calmer's smaller 6-Tooth Sprockets fit both 40 and 90 series JD heads. |
The Test Results
We converted half of our test corn head to the CALMER™ 6-Tooth Sprocket leaving the other half with the factory
8-tooth sprocket. We did multiple kill stops at normal ground speeds and bagged loose trash on both halves,
weighed it, and compared the difference. Reduction of trash intake was visibly noticeable from the windshield of
the combine and also confirmed by weight comparison test data (see photo - above and chart below).

| Step 2 Install CALMER™ Revolving Window Knife Rolls |
The Problem -
Straight fluted stalk rolls and straight fluted knife rolls have too much overlap in the
entry area. When rotating at normal speeds, these intermeshing flutes have no entry
window preventing the corn stalk from engaging easily with the flutes. This slight
hesitation gives the gathering chain lug an opportunity to break off the top portion of
the plant (see lower left photo). This excessive overlap also causes stalk breakage at
the nodes during lateral whip.

| To Demonstrate To demonstrate this stalk roll problem, I turned a food mixer on high and held the egg beaters so they were horizontal. Then I took a plastic straw and while holding the straw vertically, I tried to make the straw enter the beaters from the end, like a corn stalk entering a corn row unit. The straw bent over and never engaged with the overlapping flutes of the egg beaters. This is a great visual of what happens when we try to pick corn with straight fluted intermeshing stalk rolls (see photos below). This is dangerous!!! Do not try this at home. |
| Corn picked with straight fluted intermeshing stalk rolls |
The Solution-
Install Revolving Window Knife Rolls. Calmer’s™ Rolls utilize 4 flutes instead of 6 which create 2 windows per
revolution and 4 modes of action. These modes repeat several times to successfully separate the ear and chop
the stalk.

| Pinch |
| In this mode the stalk rolls have rotated closing the window. The knives then pinch and lacerate the stalk to gain adequate traction for implosion of the plant. |
| In this mode the rotating knives pull the plant downward. This causes the base of the corn plant to kink and buckle. The plant continues to be pulled downward. |
| Pull Down |
| Release |
| In this mode the intermeshing knives release the corn stalk for lateral movement. This is necessary because the corn plant is being pulled downward as the cornhead is moving forward. This allows the corn plant to stay in a mostly vertical position during implosion, regardless of ground speed. |
| The trailing edge of the flutes are hard surfaced to make them self sharpening |
| CALMER Revolving Window Knife Shells™ |
| "We tested one row of Calmer's new Knife Rolls last fall. I drove the grain cart and I could easily identify the row picked by Calmer's Revolving Window Knife Rolls because the stubble was only 12" tall. The other rows, with factory knife rolls shells, looked like they had been picked with an ear corn picker and were at least 36" tall." Josh Curry |
| Marion demonstrating the CALMER™ Trash Reduction Row-Unit Upgrade Kit at Farm Progress Show Exposition - 2004 |
| Step 3 Install CALMER™ Beveled Stripper Plates |
The Problem-
The original straight stripper plates are not formed to match
the natural shape of the bottom side of the corn leaf. During
ear separation, the plant leaves are pulled downward past
these straight stripper plates causing them to be
unnecessarily torn from the stalk. (see illustration to the right)
Straight stripper plates do not emulate the rounded butt of
the ear and do not allow the ear shank to get close enough
to the stalk rolls to pinch the shank. This allows the husk to
stay attached to the ear, sending the husk into the combine,
creating more material for the combine to handle

The Solution-
Install Calmer™ Beveled Stripper Plates. These beveled
stripper plates are longer to scoop up low hanging ears in
down corn. Straight in the front retrieving area to reduce
ear wedging and beveled in the stripping area to allow the
stalk to engage more ear shanks, husks, and leaves.
These beveled stripper plates have a weld hardened
surface for extended life.
