Single Disc Drills The Joy of Simplicity

Easy to operate and maintain

Right away, you'll notice details that make the Single Disc Drill easier to operate and maintain.

Single Disc Drill

The Massey Ferguson Single Disc Drill does not have a gauge wheel running next to the disc. This allows the soil to lift and flow back against the packer to be re-leveled over the seed furrow. 

Competitive drills’gauge wheels run next to their discs, firmly holding residue and soil in place. If the residue is not cut, it is tucked into the seed furrow. Even when seeding into very wet, humid residue, the Single Disc Drill operators have not reported tucking as a problem. They also haven't had to wait for residue to dry.

On other drills, the gauge wheel position also causes sidewall compaction, or smearing. By trying to hold the soil in place, certain conditions actually compress soil against the blade, causing a compacted seed furrow. Smeared or compacted sidewalls also inhibit root development and, ultimately, yield.

The patented "opposing single discs" lift and displace the soil between the two narrow 6-inch rows. The loosened soil coming off of the twin discs, flows back against the trailing packer which re-levels and firms the soil over the seed rows. This soil displacement eliminates sidewall compaction, hair pinning, and open seed furrows while leaving a 6-inch blackened strip to encourage soil warming.

Mid Row Fertilizer Depth Cam

A cam block in the holder on the mid row fertilizer units allow the depth of the openers to be set higher or lower in relation to the seeding depths. Rotating the cam to the different depth slots allows you to precisely control fertilizer depth.

Row Units

Each 30-inch wide tool bar on the 9800 single disc drill consists of two pairs of seeding disks and two packer tyres. Additionally the tool bar can be configured with optional mid nutrient placement disc openers (A). Each pair of seeding disks are mounted horizontally opposed on a common strut. With all of the openers in a single row, the opener spacing stays uniform in turms and when drifting on side slopes. The amount of soil coverage over each seed row is more uniformal with this arrangement because there are no back rows to cover front rows.


The bulkhead at the rear of the drill has the connections for the air system neatly arranged and labeled for operator convenience. Keeping all of the connections above the hitch point keeps them out of harm's way.

Lift Assist Rear Hitch

Weight is automatically transferred to the lift assist hitch and tractor drawbar during wing up, by an accumulator system on the drill. Used on the larger drills, the lift assist hitch allows drills from 30ft to 50 ft with no reconfiguration of the main frame undercarriage.


All main frames and large wings use a dual walking tandem axle design. 3-inch walk beam pivots and spindles ensure adequate strength. Small wings use single wheels with the same 3-inch spindle for comminality of parts. 20 ply tires are used on the main frame to match the weight of the drill.

Seed Tube Removal

Taking off seed tubes for cearing debis or improved access to the disk only requires removal of a spring pin. The tube then simply lifts up and out of the opener assembly.

Extra Heavy Frames

6 x 8 x 1/2- inch wall tubing at the front and rear of main frames and 1/2 inch wall tubing throughout.

Precise down pressure

The down pressure is precisely maintained by a hydraulic cylinder on each tool bar. The pressure is constant throughout the entire range of cylinder travel. Pressure on the cylinders is controlled by the operator on–the-go. A pressure gauge, mounted for easy visibility, allows the operator to monitor down force on the toolbars.

Depth control adjustment

Height of the drill frame sets the depth of the row units. As the drill rises, the discs seed shallower. As the drill frame lowers, the discs seed deeper. Packer tires hold the discs precisely at seeding depth.
Depth control collars, in the frame cylinders, hold frame exactly at desired height.
