750A Drill

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.

A key argument for the 750A Drills is their low power requirement. Even for the largest 6-m (19.7-ft) model, a tractor with 104 kW (140 hp) is capable of handling the drill efficiently. This also translates into low fuel use and contributes to low crop establishment costs overall.

A single-row following harrow is optionally available (option code 6040) to help provide a clean finish to the work.

The harrow features 10-mm (0.4-in.) spring steel tines and can be adjusted to four different working positions. The harrow is raised and lowered together with the drill openers.

Row marker on a 750A drill

Row markers (option code 4100) 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.

Notched disk blade on row marker

Markers feature a 406-mm (16-in.) notched disk blade with a 102-mm (4-in.) wide depth gauging band.

For operators working with AutoTrac™ guidance systems, a no-marker system option (option code 4200) can be ordered.

750A Drill metering system

The 750A Drill utilizes a pneumatic metering system, which allows for seed rates from 1.1 to 412 kg/ha (2.4 to 908.3 lb/ha). The metering device typically operates to 7-10 percent coefficient of variation. Differences in metering accuracy are +/- 1 percent for diagonal and length-wise inclination (F.A.T. CH – University of Switzerland).

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 of the 750A is capable of seeding a wide range of crops at either low rates or high rates because of the accurate metering system.

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.

Mechanical metering system with ground wheel

Electrical metering drive included with ISOBUS/GreenStar™ option

Base specification machines are fitted with mechanically driven metering systems. The optional GreenStar display/ISOBUS control feature (option codes 6200 and 6210) offers the electric drive of the metering system. This provides easier calibration by allowing the operator to adjust seed rates incrementally from the tractor cab.

A calibration tray is supplied with each machine for fast easy and stress-free calibration.
