OEM PROBLEM
No Feeding Chamber
No stalk roll is able perform properly without allowing the stalk into the space to be processed. This is the feeding chamber in the entry area. All factory rolls have the same length flutes and therefore a continuous overlap in the entry area, which creates a wall of rotating steel and prevents the the entry of cornstalks.
Mechanically, this flawed design results in the premature wear in the first few inches of the stalk roll, while the remaining length of the blades stay in “like new” condition since stalks cannot travel further up the row unit.
Cornstalks CANNOT engage with factory rolls or become processed due to the continuous overlap in entry area.
CALMER SOLUTION
Patented “Open window” Feeding Chamber
Through integration of multi-length blades the Calmer BT Chopper® Stalk Rolls have an opening and closing window (illustrated in the video below). The only stalk roll on the market with a patented “open window” feeding chamber for accepting, and positively crushing stalks shortly after they are admitted. The design feature enables cornstalks to travel efficiently into the row unit to become processed especially beneficial in down or damaged stalk conditions.
Features perform in all crop conditions, guarantee the traction of stalks for processing, provides longer stalk roll life, reduces low ear snap (butt shelling), and prevents the bulldozing of stalks at the end rows.
Cornstalks EASILY engage with Calmer’s patented “open window” feeding chamber to become processed.
