• Large under-frame clearance for maximum trash flow
  • Adaptable for split seed/fertilizer distribution – Double cups optional
  • Renowned 620 tyne assemblies – Greater than 113kg (250lb) breakout
  • Fluted rollers – Suitable for a wide variety of seed types
  • Large wheel equipment – For excellent flotation
  • Big capacity grain and fertilizer boxes – Less stops between refills
  • Full level lift system – excellent depth control
  • Easy to calibrate wide range gearbox
  • Remote greasing for grain and fertilizer shaft bearings
  • Gas struts on lid

Numerous configurations are available for the operator to direct drill, adopt summer cropping sowing practices, carry out conventional seeding or somewhere in between with min-til or trashfarming. The addition of cultivating tynes enables a quick and easy conversion from min-til to trash farming or conventional seeding.

In the Shearer tradition the direct drills are robust and heavily constructed in the areas that count and built to last. The result is less down time, for a more efficient and cost effective operation.

Simple Calibration

All models feature electronic scales for easy sowing rate calibration.

Electric Drive Option

An electric drive option is available to facilitate alteration of sowing rates from the tractor seat.

Excellent Depth Control

Large, high-flotation tyres provide accurate depth control over varying soil conditions, helping to promote uniform planting depth. All models have a level lift system with three series connected hydraulic cylinders. One cylinder is connected to the hitch and controls the fore and aft level lift function. Cylinders on each wheel, which operate in conjunction with the hitch cylinder, control the depth of sowing.

Large Hopper Capacity

All sizes have large seed and fertilizer compartments for fewer stops between refills. For example, a 27 row drill can hold up to 660kg of wheat and 1100kg of fertilizer.

Extra-Large Sight Glass

An extra-large sight glass provides the operator with a quick visual reference of material level in the front bin.

Customise and Enhance

Many options are available for tailoring the machine to your particular needs. These include bolt-on extensions, electric drive systems, air assist blower kits and a variety of openers.

End-On Tow Option

Don’t be limited by narrow gates and roadways. Reduce transport width with the end-on towing option.

Lid Gas Struts

Gas struts are fitted as standard on each end of the hopper lid for operator convenience and safety.

Easy Maintenance

Maintenance time is reduced, with the easily accessible remote greasing facility which is fitted to the grain and fertilizer shaft bearings.

Double Sowing Option

Double cups are an option for operators wishing to split the delivery of grain and fertilizer when deep banding or placing different material in alternate rows.

Platform With Safety Rail

Both 4 and 6 row models feature a wide heavy duty platform and safety rail.


All 4 and 6 row drills feature a 31 speed, fully enclosed, oil bath gearbox to give simple calibration and wide range of sowing rates for both seed and fertiliser.

Airmatic Option

A hydraulically powered blower is available as an option to boost seed flow. Air volume is controllable via a tool-free adjustment knob on the hydraulic motor.
