Digman: Maximizing Harvester Productivity in Snaplage
- The first step to get deck plates adjusted right. If they are too narrow, it will plug. If they are two wide, shelling will occur.
- Speed is limited with a snapper head. If you run too fast, you’ll overrun the stalk rolls and drop ears.
- A lot of people minimize the cut length to take load off of the kernel processor. You can adjust TLC up or down to promote proper feeding. Length of cut doesn’t really matter with snaplage.
- A recutter floor provided by some manufacturers can be used in an attempt to reduce husk size.
- Recirculating screens are another method to use in attempt to reduce husk size.
- KP setup is going to be tight, but most don’t recommend less that 1 mm.
- Monitor the material coming out of the KP.
- Check clearances on each side, and adjust end stops as needed.
- Harvest at the right moisture – 34 to 36 percent kernel moisture (black layer). This is the biggest thing you could do. Higher moisture means less developed protein and more degradable starch. Don’t err on the dry side, he said.
- Keep things tight. Run a really tight KP gap and consider recutter floor/recirculating screens. Remember it’s about increasing surface area of the corn kernel.
- Don’t overfill trucks. The density of snaplage is about 16 pounds per cubic foot; and husks have a tendency of blowing out onto the road.
- Pack well, fill rapidly and keep air out – typical advice for any type of silage.
- Feed out rapidly and keep a clean face. This is just as important as in any ensiling process.
