CALMER CORN HEADS, by design, allow you to harvest faster and more economically
than ever before, maximizing your profit potential.

By combining our patented single chain design with our low profile, super short poly hoods
and dividers, we have created one of the lightest weight row units in the industry.
Strategically Realigned
Calmer heads are realigned to allow proper material flow from the tray to
the feeder house, reducing ear toss and providing for maximum flow rates
in high yielding, and in high-speed harvest conditions.
Patent Pending

Outstanding Performance
An essential part of Calmer's Patented single chain design, the UHMW
(Ultra High Molecular Weight) polyethylene ear guides, form a retaining
wall to maintain engagement of the ears with the enlarged hardened steel
gathering chain paddles.  By eliminating the second chain, chain guide,
drive sprocket, drive shaft, idler block, idler sprocket and chain tension
spring, we reduce the weight of the corn head by thirty-plus pounds per
row and significantly lower horsepower requirements.  Another added
benefit, after eliminating half the moving parts on the corn head,
maintenance cost for the Calmer Corn Head is much lower.
Our high profile, shorter snouts
are among the shortest on the market today making it easy to
maneuver through narrow rows and around tight contoured
areas.  The low profile flat back deck cover design (patents
pending) help keep dislodged material engaged with the
gathering chain paddles and moving to the cross auger.  The
deck covers feature self-aligning valleys that make it a snap to
install, and a lynch pin keeper that allows you to easily remove
the hood assembly without tools.

Calmer Ag Research featured in Successful Farming Magazine
Successful Farming magazine profiled Calmer Ag Research in it's November 2003 issue.  The
article discusses the Calmer Corn Heads for 15-and 20-inch rows and the company's new
trash reduction conversion kits.
According to Successful Farming:
"Calmer simply removed one gathering chain plus all the gears, shafts, bearings, and idlers
that went with it.  He also had the gearboxes of the IH 800 corn heads he started with milled to a
width of just under 15 inches."

Instead of two gathering chains per row working in unison, Calmer's head has one gathering
chain per row, outfitted with 4 large plastic paddles.  That chain is teamed up with an ear guide
on the other side of the row."

"The advantage of that approach goes beyond row width.  Calmer's heads also weigh about 50
pounds per row less than conventional heads.  "That weight difference is huge on a 12-, 16-, or
18- row head, " says Calmer."

"Equally if not more important, Calmer's heads require less horsepower to run.  That translates
into less stress on the driveline.  Calmer's patents gave him a strong position in the market for
15-inch heads, and that's the market he concentrated on until recently.  Two years ago, he
started converting John Deere heads to 15-inch rows in addition to the IH 800 heads."

These combo stripper plates are longer, allowing for efficient removal of low
hanging ears in down corn.  Our stripper plates are constructed with a sleek,
straight design, which will reduce ear wedging.  The bevel in the remaining
stripper plate allows the knife to knife stalk rolls to engage more corn leaves,
shanks, and husks reducing trash intake and horsepower requirements

Calmer Corn Heads To Set Another
Record With 32-Row Corn Head

ALPHA, Ill., September 5,  2013 — Calmer Corn Heads will display the world’s first 32
row 15 inch corn head at Husker Harvest Days, September 10-12, 2013, in Lot 1141.
The corn head is 40 feet wide with 32 rows of 15 inches.

Calmer 32-row corn head
This corn head is also equipped with SUPER Calmer BT Chopper Manual Adjust
Trash Reduction/Decomposition Kits. A number of “World’s Firsts” have been
displayed by Calmer throughout the years at the Farm Progress Shows.

Some examples are:

• World’s first 15-nch corn head, a 16 row 15 inch (2002).

• Largest 15-inchcorn head, a 24 row 15 inch corn head (2009).

• World’s first chopping/shearing stalk roll that processes the corn stalk into pieces 1
inch long that are also shredded (2010)

• World’s first 12-inch corn head (2012).

• World's most number of rows with 30 row 12 inch corn head (2013).

Marion Calmer, through the non-profit Calmer Agronomic Research Center, has been
involved in the research and promotion of narrow row corn since the early 1990’s –
planting corn in 12-inch rows as early as 1994. His experience demonstrates that
equidistant spacing between plants improves light interception and yield potential while
a denser canopy reduces erosion and weed control costs.

Calmer Corn Heads specializes in manufacturing corn heads for narrow row corn and
looks forward to meeting producer’s growing needs for futuristic corn heads. For more
