Description of Machine
The Duncan ‘Enviro DD55’ is a Double Disc drill.
The large split hopper is mounted on a robust centre
frame accommodating wide tyres and a 2 point linkage
at the front.
Sowing depth is controlled by depth stop collars on the
main wheel leg rams. 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 ground speed proportional
electric drive system. Seeding ceases automatically
when the machine is raised into the transport postion.
The wings may be hydraulically folded up for legal
tranport width.
Working Principle
The air flow, metering units and electric drive system
are easily 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.
