750A Drill models

The 750A Drill range comprises three different configurations with working widths of 3 m, 4 m and 6 m (9.8 ft, 13.1 ft, and 19.7 ft). All 750A Drill models feature the ProSeries™ Openers with an opener spacing of 166 mm (6.5 in.), allowing trash or cover-crop material to pass easily between without blockages.

Both 3-m (9.8-ft) and 4-m (13.1-ft) models feature a single metering system. The 6-m (19.7-ft) model features two metering units and the ability to switch either metering unit on or off to accommodate different tramline widths or to avoid overlapping already-seeded areas.


Row markers are available to help take the guesswork out of matching drilling passes in the field.

The 3-m (9.8-ft) and 4-m (13.1-ft) models feature simple one-piece markers mounted behind the seed hopper. The 6-m (19.7-ft) model features heavy-duty folding markers mounted to the frame in front of the seed hopper. All markers are equipped with shear-bolt protection.

Metering system overview

The 750A Drill utilises a pneumatic metering system, which allows for seed rates from 1.1 to 412 kg/ha (2.4 to 908.3 lb/ha). Due to the conical hopper design, it is possible to continue seeding until a residual quantity of only 500 g (1.1 lb) is left in the seed hopper.

The metering system can be adjusted between normal seed settings (e.g., cereals) and fine seed settings (e.g., rape) quickly and easily without the need for tools. In addition, large seeds like peas and beans can be metered without special inserts.

3-m (9.8-ft) and 4-m (13.1-ft) models feature a single metering device, and the 6-m (19.7-ft) model is fitted with two.

Seed delivery system overview

The totally enclosed central cell wheel of the metering device accurately meters the required volume of seed discharged into a venturi cone. At the venturi cone, the seed is mixed with the air stream and conveyed to a distribution head.

Air is supplied by an efficient, hydraulically driven fan powered from the tractor. A fan speed sensor with low-speed alarm is fitted.

Heavy-duty frame

The durable, heavy-duty steel frame features large structural members to withstand the stresses of tough seeding conditions. The opener rockshaft, rotating bearings, and hydraulic system anchors are particularly strong to provide a long working life.

The 3-m (9.8-ft) machines feature a single, rigid frame. The 4-m (13.1-ft) and 6-m (19.7-ft) frames feature hydraulic folding wings to enable a transport width of only 3 m (9.8 ft). Folding is easily accomplished via the tractor selective control valves (SCVs). A mechanical locking link provides additional safety for transport situations.

ProSeries™ Opener

In conditions ranging from reduced tillage to conservation tillage and to the demanding conditions of no-till, the ProSeries Opener places each seed with precision at a specific depth, ensuring excellent seed-to-soil contact for even germination. Each opener is individually suspended to follow the ground contours and variations of the soil.

Each ProSeries Opener features individual adjustments for:

  • Depth gauge wheel – for setting seeding depth
  • Press wheel – for pressing the seed gently into the furrow
  • Furrow closing wheel – for covering the seed and closing the seed trench

The openers are mounted in two ranks with a 165-mm (6.5-in.) row spacing. On a 3-m (9.8-ft) 750A Drill, there are two ranks with nine opener units each. On the 4-m (13.1-ft) 750A Drill, there are two ranks with 12 opener units each. The 6-m (19.7-ft) 750A Drill has two ranks with 18 opener units each.


750A Drill hydraulics

750A Drills require three selective control valves (SCVs) plus a free-flow return, all of which are capable of simultaneous operation:
  • One double-acting service for opener rockshaft raise/lower
  • One double-acting service for marker operation and wing open/close (4 m and 6 m [13.1 ft and 19.7 ft] only)
  • One single-acting service for the pneumatic drill system fan
  • Free-flow return is also necessary for the return oil from the pneumatic drill system fan.
