SeedStar™ variable-rate drive system
Variable-rate drive

Variable-rate drive

With the SeedStar variable-rate drive, the operator can manually change the seeding rate on the go, right from the tractor cab.
The SeedStar monitoring system:
  • Allows the operator to match seed population to differing soil types or to irrigated vs. dryland soils
  • Allows the operator to program up to six different seed rates into the system; then, during the planting operation, the operator can select any of the programmed rates and change seed rates
Hydraulic oil flow from a closed-center tractor selective control valve (SCV) or power beyond goes to the hydraulic motor through a solenoid flow control valve controlling the motor speed.
 
When a programmed rate is selected, the microprocessor energizes the solenoid valve, changing the oil flow rate. The hydraulic motor speed sensor provides a signal to the microprocessor of the motor speed, ensuring the system is delivering the new seed rate.
 
A motion sensor and rotary potentiometer provides signals to the microprocessor to ensure the planter is in the plant position. The rotary potentiometer turns the seed drive on and off as the planter frame is raised and lowered.
 
For the operator to manually control the population rate, these components are required:
  • SeedStar monitoring system
  • GreenStar display
  • SeedStar variable-rate drive
  • Radar
NOTE: The SeedStar variable-rate drive is available for 1700, 1710, 1720, 1760, 1760NT, 1770, 1770NT, and 1780 Planters.
The variable-rate drive system can be installed on the following planter monitoring systems:
  • Generation II SeedStar with Original GreenStar display
  • SeedStar 2 monitoring with GreenStar 2 or 3 display
  • SeedStar XP monitoring with GreenStar 2 or 3 display
 
Take special note of the SeedStar version when ordering controller wedge boxes needed for the variable-rate drive system.
 
NOTE: These additions to a planter with half-width drive disconnect may require an additional frame control console: BA30921 for the 1760, 1760NT, and 1770 12Row30 Planters.
