Seed Accuracy –
To achieve more accurate seed spacing it is critical to control seed roll. Adjustable wings (14) have been
mounted on the inside of the shoe which move in and out according to soil conditions. The goal is to try to pin
the seed as it falls into the furrow. If the soil wraps too soon the seed depth will vary as there is loose soil
underneath the seed. If the wings are back too far the seed has an opportunity to roll.

Working Position Sensor –
The working position sensor is used to turn off the row units and shakers while turning around at the end of the
field. On a planter with front depth wheels this sensor is mounted on the depth wheel itself (15). The top hole is
slotted so that the turnbuckle moves up and down as there tire is lifted off the ground. The sensor senses the
turnbuckle end to know if the planter is up or down.
On a drawbar style planter without depth wheels it is mounted to sense the position of the front drawbar (16) to
determine of the planter is up or down.
