Variable Rate Drive Motor and Valve

The VRD motor turns the seed meter drives at a speed controlled with the valve. The seed population entered in the monito determines the motor speed. The solenoid valve receives electrical signals from the controller and adjusts oil flow to the motor. The planter configuration determines the quantity of VRD motors.

Variable Rate Drive Motor Speed Sensor

A motor speed sensor is attached to the output shaft of each VRD motor. The sensor detects the exact speed of the motor for the controller.

Parallel Arm Height Switch for Integral Planters

Two parallel arm height switches are used to sense when the planter is raised and lowered. Both switches must be in the same position to indicate a change of raised or lowered. When the planter is raised, the controller stops the VRD motors. (See Adjust Parallel Arm Height Switch in this section.) (See Calibrate Common Start and Stop Height in SeedStar™ 2 Basic Planter Configuration section.)

A45210-UN-27NOV98

Height Sensor for Drawn Planters

The height sensor switch is used to sense when the planter is raised and lowered. When the planter is raised, the controller stops the VRD motors. (See Calibrate Common Start and Stop Height or Calibrate Separate Start and Stop Height in SeedStar™ 2 Basic Planter Configuration section.)

A44952-UN-17JUL98

Variable Rate Drive Wheel Motion Sensor

The wheel motion sensor is used as a safety feature validating the ground speed signal from the radar or GPS receiver. The wheel motion sensor detects motion and indicates that the planter is moving.
