Description of Machine
The Duncan ‘Enviro’ is a triple disc direct drill.
It has two boxes for either seed combinations
or traditional seed fertiliser mixes. The
boxes are mounted on a heavy duty frame
accommodating large end wheels which are
hydraulically operated allowing adjustable
sowing pressure and good transport
clearance. Both disc opener and double disc
are independently sprung allowing good
contour following ability. Sowing depth is
controlled by adjustable rubber tyred depth
wheels. The quality European type peg roller seeder
system handles all seeds from turnip and rape through
to peas and maize. The seeder drive is via a clutch
and variable speed gearbox from the drive wheels.
For transport the drive is easily disconnected using a
freewheeling type hub fitted to the drive wheel.
Working Principle
The gearbox, pegged seed rollers and seeder flaps are set
to give the desired seed rate. The front disc pre-cuts the
surface followed by the double disc creating the seed bed.
Seed/fertiliser flows down the flexible convolute tubes between
seeder and double disc units dropping into the prepared seed
bed. A suitably profiled depth wheel maintains the double discs
at a predetermined depth and closes and compacts the soil
over the deposited seed.
