Automatic Depth & Distance Controller

Consistent control improves capacity, reduces wear and delivers a cleaner, higher quality product!
The RiteDepth system provides automatic, accurate and consistent depth and distance control on root crop harvesters and vegetable flail mowers (toppers).

"Wonderful addition to our windrower! Much more even flow; cleaner digging with fewer cut potatoes."

The system works with one or  two rugged sonar sensors  mounted to read off the top of the row and connected to the shared mounting frame. Signals from the sensors are interpreted by a small controller which automatically lifts and lowers the shared frame as needed. This maintains a very consistent digging depth even when the harvester works in hilly or uneven terrain or when soil conditions change (from dry to wet or from packed to loose soil).

Digging depth or topper distance control are  among the most important factors in optimizing equipment performance and marketable yield. Gauge wheels or rollers are common mechanical devices used to achieve the correct depth or distance. These systems have limited versatility requiring the operator to make frequent on-the-go adjustments. The RiteDepth system automates the adjustments, improving performance and easing operator stress.
