With the Agriseeder drill from Erth Engineering listed for the primary time, this yr’s Ultimate Guide to disc coulter seed drills displays an excellent greater alternative of machines for single-pass institution of grains and oilseeds, companion and canopy crops, and grass leys.
With the burgeoning use of canopy crops to construct soil fertility and natural matter, and the power of discs to work successfully with giant volumes of floor vegetation, such a drill is more and more well-liked.

Hydraulic auto contour management is a function of the Agriseeder from Erth Engineering, in Northern Eire, which is designed to attain constant coulter stress and seeding depth over undulating floor.
Primarily concentrating on grass leys, fodder cropping and canopy crops, the 3m and 4m implements have two rows of notched disc openers, every set at an angle to the route of journey with a disc-cleaning seed coulter alongside.
They’re mounted in eight-disc sections on pivoting frames, with interconnected hydraulic cylinders to generate even downforce and seeding depth throughout the working width.
Patrons can go together with the usual 400-litre frame-mounted hopper, or the 1,000-litre choice for higher productiveness and when wanting to use fertiliser on the similar time.
There’s additionally scope so as to add a 70-litre secondary hopper for making use of micro fertilisers, small seeds and slug pellets, utilized both down the spout, broadcast to the floor or positioned individually by way of twin-outlet coulters.
Further fashions added to the Avatar SD vary prolong the seed cart format established by the 12m Avatar 12.25 SD to a few narrower sizes.
Like the largest drill within the line-up, the 8m, 9m and 10m fashions include a big hopper – 6,400 litres on this case – in both triple-compartment type as customary, or double-compartment as an choice.
This seed and fertiliser configuration can be used for seed-only sowing.
A toolbar is mounted to the rear carrying one inline row of SingleDisc coulters spaced 250mm aside.
This contrasts with the 3m to 8m sizes which have 167mm coulter spacing throughout two rows and a hopper mounted overhead.
The Moore Uni-drill disc no-till seeder vary has been expanded by a wider mounted model that delivers additional output on bigger tractors.
This 3.4m working-width machine additionally introduces an 850-litre hopper that now options on different fashions, growing seed capability from 700 litres on the 3m mounted and trailed variations.
All sizes can be found in 125mm arable and 90mm grassland row spacing configurations, utilizing 410mm notched disc openers with a tungsten seed coulter alongside.
These are mounted in pairs on a trailing arm with rubber inserts for the arm-mounting clamp permitting vertical motion, whereas offering as much as 120kg stress – up from 94kg for improved functionality in laborious soils.
A latest newcomer to UK no-till drill market from France, Novag has expanded its vary of trailed T-ForcePlus disc coulter seeders with 8m and 10m sizes, in addition to a smaller 2.5m mannequin that joins the diminutive 2.25m machine.
All variations can ship fertiliser positioned alongside seed from separate L-shaped blades that type an inverted T- slot, with a 575mm scalloped-disc opener positioned between them.
Particular person hydraulic cylinders can apply as much as 500kg of downward stress to the coulters for constant penetration, with automated adjustment dependent upon soil-resistance measurement.
Penetration depth is regulated by a pair of V-angled rubber press wheels behind the disc opener.
Whereas the brand new 10m T-ForcePlus 950X is confined to 40 rows at 250mm spacing, the 8m 850 can run 40 rows at 187mm spacing or 32 rows on the 250mm setting.
A wider working mounted drill has been added to the Weaving GD drill line-up, which includes a twin-disc opener meeting set 25deg from vertical to elevate a “flap” of soil with seed positioned beneath fairly than a vertical slot.
The 4m GD 4000M enhances the 3m model for growers with a sufficiently big tractor, and makes use of the 166mm row spacing widespread all through the vary.
In distinction, the 6.4m trailed mannequin, in each seed-only and combi configurations has been dropped, leaving the 6m and 8m variations on the prime of the line-up.
