A kernel processor is available factory installed for the 3975 Pull-Type Forage Harvesters (PTFH).
Two large-diameter rolls with sharp heat-treated flutes crack whole-corn silage for better digestibility.
The fluted rolls accelerate the crop into the auger.
The kernel processor works as the top roll rotates at 1940 rpm and the bottom roll rotates at 2830 rpm.
This difference in speed between the rolls creates a tearing action; it nicks the kernels, breaks the cobs, and shreds the stalk.
More feed is digested
By processing corn silage, more surface area is created for the microbes (the bacteria in a cow's stomach) to digest the fibrous material and transfer the available starch into energy.
When more feed is digested, more energy is available to the animal. When more energy is available, it can result in greater milk production and daily gain efficiency.
Recommendations and requirements
The kernel processor works well in whole-plant corn or for ear-corn silage. It can be bypassed to use in grass or legumes.
For any machine configuration, a minimum of at least a 152 mm (6-in.) right-hand wheel extension is required and is included with option code 7600.
If a 24-tooth sprocket with a full set of knives is used with the kernel processor, an anti-carryover shield and lower-front feedroll pan may be required to prevent crop carryover.
The kernel processor is driven by belts off the cutterhead driveshaft.
