If you are a budget conscious operation, considering how to keep your hard earned dollars inside your bank account, instead of at your tracktor and implement dealer; consider upgrading your old John Deere 40 series corn head produces in the 60’s and 70’s; or refurbish your 90 Series corn head originally produced in the 1980 into the 1990’s with industry leading parts that restore performance to equal anything that will cost hundreds of thousands of dollars new from a manufacturer.  The ‘bones’ of your old Deere head are just fine, unless you’ve changed row width, there’s probably a good deal on a used head near you.  Install a Calmer kit to put industry leading performance into every row unit!

We have a 100% Satisfaction Gaurantee – we will buy back any kit that you do not believe performs as we claim.

With 20 years of technical and manufacturing refinements the BT CHOPPER® is a mature technology upgrade for nearly any corn head produced in the market today.  The benefits over ‘lawn mower’ style chopping corn heads are tremendous, but start with reduced fuel consumption in the field.  We have done studies that show 60% less trash is entering your threshing system, which with proper combine settings, will give you faster and cleaner threshing.  We make the claim of the World’s Only All Weather Stalk roll, and while you may not want to drive all night, the closing power of the wear bar, in combination with the 10 intermeshing blades will chop and chew early season green stalks and late season dried stalks with dew or frost.
