Gravity seed distribution
This reliable system has been utilised on Duncan Drills for decades. It is easy to calibrate and use, requires no tractor hydraulics to run it and it is incredibly accurate due to the seeds being metered from individual outlets for each run.
Seed and fertiliser is stored in a box above the drilling tines or discs and drops into a metering peg roller system with coarse and fine wheels and flow control flaps to handle different seed sizes and sowing rates.
Metered seed and fertiliser then drops down flexible hoses to the point of contact with the ground.
