The Renovator MK4 is the premium gravity box drill in the range.
Featuring 125mm or 150mm row spacings, the MK4 can be configured for a wide range of jobs, from planting grass in the high rainfall rolling hills of the South Island, to planting cereal crops on the dry plains of Australia.
High capacity boxes coupled with the accurate peg tooth seeder units mean you can sow accurately and for longer with the renowned Renovator reliability.
Sturdy 25mm coil tines with the Baker boot are spaced out over four toolbars for optimum trash flow. Commonly coupled with disc openers and tine harrows, the MK4 will make a beautiful job in the most challenging conditions.
Choose from 3 metre and 3.5 metre models, to sow large hectares in a range of terrain and conditions.

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.
25mm Coil Tine
The tine has minimal sideways movement so that it tracks straight and it will follow an opening disc.
The tine pulls back before it lifts up out of the ground, so it is not placing seed on top of the ground.
Made from solid spring steel with no drilled holes to weaken it so it’s very durable with minimal breakages.
Staggered tine mounting layout to assist trash flow.
The Baker Boot is replaceable.
The tungsten carbide leading edge with a positive rake angle on the point penetrates the ground and opens up a slot.
The seed and fertiliser are placed at different depths for optimum germination.
The wings & heel of the boot create a cavity containing all of the key ingredients being seed, fertiliser, moisture, air and loose soil which is ideal for fast germination and rapid root development.
Use the Duncan Seed Drill app on your phone for easy and accurate job configuration and calibration of any new or existing Duncan Renovator or Duncan Enviro drill, and take your drilling operations to the next level of productivity.
The Duncan seed drill app contains step-by-step user guides for making calibration and mechanical adjustments to your drill. Great for any new operator or if you're just a bit rusty yourself!
Calibrate multiple machines with the app, and get every operator set up with it too so they can do calibrations from their own phone.
Calibrating a ground drive drill with seed or fertiliser will display the required mechanical settings.
Connect wirelessly to a Duncan E-Drive drill to set up the sowing rates and run calibrations while you are right beside the drill.
