RP2 Sowing System

The Knuckey RP2 Sowing System can be mounted through your new or existing bars to enable precision seeding. The assembly includes a heavy duty mount along with the integral adjustable sowing tyne and large 450mm press wheel. This system provides perfect seed depth control and pressing of soil to seed, allowing optimum germination, along with the ability to place the fertiliser separately to the seed. A single pin height adjuster allows for fast and efficient changing of sowing height. Crucially, this assembly is mounted independently to the ripping tyne to ensure tyne chattering and breakout has no effect on seed placement or assembly life.
