Quick Start Overview-Variable Rate Drive

A59897

The Quick Start button is to the left of the motor rotation button.

A skip is an area where seed is expected, but has not been planted.

The Quick Start feature allows the operator to reduce a skip when the planter starts from a stop. Quick Start reduces the skip to approximately 0.3-1.2 m (1-4 ft.).

When Quick Start is selected and activates, the controller engages the motors at the minimum operational rpm represented by a target ground speed. The motors overpopulate until actual ground speed reaches the target speed calculated by the controller.

For example:

Population Row Spacing Minimum Speed
37 000 seeds/hectare
(15 000 seeds/acre)
76 cm
(30 in.)
4.8 km/h
(3 mph)
74 000 seeds/hectare
(30 000 seeds/acre)
76 cm
(30 in.)
2.4 km/h
(1.5 mph)

 

The controller must detect the four following conditions before Quick Start activates.

  • Quick Start must be enabled in Planter Configuration, Meter Drive Setup.
  • Actual measured radar speed must be below minimum ground speed.
  • Planter wheel motion must be detected.
  • Planter frame height must indicate a lowered position.

1. Raise planter.

2. Begin forward travel in a low gear at high idle.

3. Select QS Reset on display.

4. Lower planter. When the height sensor indicates a lowered position "QS 6" appears on screen and begins counting down. The VRD motors engage at the minimum speed.

5. Gradually shift up to planting speed.

When timer reaches zero, the controller checks for a minimum ground speed of 1.6 km/h (1 mph). If minimum speed is not reached, system shuts down. If speed is over minimum, but less than target, timer resets to six seconds. When timer reaches zero again, the controller checks for the minimum ground speed again. If minimum speed is not reached, system shuts down. If speed is over minimum, but less than target, motors continue to run below optimum limits and a warning is issued to increase speed. If target speed is reached at any point while timer is active, Quick Start deactivates and normal operation resumes.

During normal operation, a visual indicator appears on the RUN screen when motors are operational. The gear indicator sections fill in, one at a time, then turn

solid green to indicate at least one motor is operational.
