Grede Columbiana, Columbiana, Alabama Material: Ductile iron (80-55-06).
Process: Lost foam. Weight: 24 lbs.
Dimensions: 22.5 x 45 in.
Application: Corn field harvest and precision stalk residue management.
Corn field har est and precision stalk residue management.
• The castings work in right- and left-hand pairs and use complex intermeshing tooth and blade geometries to precisely crimp and cut corn stalk residue into the desired final size during harvest.
• The numerous crimp sites on the stalks exposed for microbial breakdown help accelerate decomposition and nitrogen release into the soil, improving next year’s crop.
• Lost foam tooling was designed to produced multiple part configurations and part numbers with a single tool with interchangeable inserts, facilitating a family of chainrolls to fit a variety of corn head models.
