Description of Machine
The Duncan ‘Enviro DD35’ is a Double Disc drill.
The large split hopper is mounted on a robust frame
accommodating large diameter tyres.
Sowing depth is controlled by adjusting the hydraulic
ram as required. The quality European air metering units
handle all seeds from turnip and rape through to peas
and maize and permits easy calibration. The seeders
are driven via a jockey wheel with individually selected
high or low ranges. For transport, the drive is easily
disconnected by raising the drill to its transport height.
Working Principle
The air flow and metering units are set to give the
desired sowing and/or fertilizer rate. The seeding slot is
opened by a unique leading scalloped disc and followed
by a plain disc. Air delivers seed down the flexible tubes
between the vee of each disc unit and drops into the
prepared seed slot. Optional press wheels, tine harrows
or following roller enhance seed to soil contact
