Unique Row Unit
How the Tempo Row Unit Works
- The seed enters the electric-drive seed meter from the seed hopper. The hopper holds 1.98 bu – enough to plant approximately 50 acres without refilling.
- Positive air pressure in the meter keeps the seed on the disc as it rotates toward the tube.
- Three singulators remove extra seeds.
- The metal flap prevents extra seed from falling into the seed tube.
- The wheel blocks airflow in the disc and shoots the seed down the seed tube.
- The seed disc is cleaned of any debris by a knockout wheel.
- A sensor detects the distance between seeds, sending the information to the Wireless E-Control iPad monitor.
- PowerShoot™ delivers the seed down the tube and into the seedbed at high speed, taking gravity out of the equation and ensuring precise placement.
- The stop wheel stops the seed as it exits the seed tube and presses it into the soil, preventing bouncing and ensuring optimal seed-to-soil contact.
A Self-Sufficient Planter
Each seed meter is driven by a small electric motor installed on each row unit on the planter. Power for the motors comes from an integrated hydraulic fan and alternator, making the machine self-sufficient.
Precision is presented as a coefficient of variation (CV). The lower the CV value, the more precisely the seed is placed. The value obtained for the 24-hour race was 18.5 percent as compared to an average of 44 percent for less precise planters in the United States.
Here are the CV results from a Tempo corn trial planting in North America:
