Extra Heavy Frames

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

Seed Tube Removal

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


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 commonality of parts. 20 ply tires are used on the main frame to match the weight of the drill.

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 30 ft to 50 foot with no reconfiguration of the main frame undercarriage.

Down Pressure Cylinders

Down pressure of each of the tool bars on the 9800 drill is loaded by hydraulic cylinders connected in a parallel circuit. Down pressure is uniform across the drill and through the entire range of motion of the tool bars. This is a marked improvement over springs that increase down pressure when stretched or compressed depending on configuration.

Down Pressure Control Box

The row unit down pressure is controlled by the operator on the go. The current down pressure is displayed at the top of the control box shown at the right. Increasing and decreasing down pressure across the drill is as simple as turning the knob below the screen. Down pressure can be set from carrying none to all of the drill weight on the toolbars.


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.

Tool Bar Lock Up

The operator can lock up the tool bars with a simple twist of the spring loaded handle (lower detail circle). This is desirable for working on the row units or for locking up the main frame units in transport. When released the rod engages the tab of the frame (upper detail circle). The lock up rod is robust enough to hold even if the tractor hydraulics are engaged to lower the units.

Row Units

Each 30-inch wide tool bar on the 9800 single disc drill consists of two pairs of seeding disks and two packer tires. Additionally the tool bar can be configured with optional mid row 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 turns and when drifting on side slopes. The amount of soil coverage over each seed row is more uniform with this arrangement because there are no back rows to cover front rows. With all of the displaced soil thrown between the disc and in front of the packer tire, more loose soil is created for packing and less open furrows are created than with competitive single disc designs. With the seed placed precisely at each edge of the packer tire, crusting is virtually eliminated as the seedling has an unpacked path to the surface. The 5 degree scrub on the packer tires compacts the soil and keeps the tires cleaner in sticky conditions. Optional holes in the mounts allow the operator to run the tires straight if desired. Optional mid row placement disc (A) place desired nutrition (NH3, dry, liquid or combination) between and below the seed rows.
