T-Slot Technology

The inverted T-slot technique ensures unmatched results across all surfaces, soil types and climates. Leading discs pre-slice an opening in front of, and in line with, the tine coulter which places the seed. The disc cuts through trash and slices through any root structure under the soil surface preventing residue from blocking the drill and enabling unwanted material to be cleared out of the seed slot by the coulter.

The creation of a disc slot ahead of the tine also helps minimise soil surface disturbance by the following coulter, preventing weed germination and giving the new seed the best possible start.
The tine and patented Z-tip coulter are centred behind the opening disc so that the front edge of the coulter simply opens up the slot already created by the disc.

The inverted “T” shape of the Z-tip coulter then creates a bulbous slot with fine tilth at the bottom and a narrow opening at the top. By moving a small amount of soil around the seed the Z-tip also mineralises local nutrients making them available to the seedling and assisting establishment.

This “T-slot” provides the perfect environment for the newly placed seed to germinate and start to grow. The tilth at the base of the slot ensures drainage so that the seed doesn’t sit in water in wet conditions and the narrow opening at the top allows the new plant to emerge without allowing the T-slot to dry out in dry conditions. At the same time moisture is retained in the environment created by the T-slot.

The Z-Tip Point

The T-slot concept was first developed by John Baker in 1976 and has been refined and improved by various drill manufacturers since then. The precise shape of the patented Simtech Z-tip has been optimised with the latest metal working processes and wear resistant materials.

Millions of hectares of work have proven the design. Tungsten has been braised onto the leading edge and base of the forged points in key areas to maximise wearing life, minimise down time and ensure return on investment for every Simtech owner.

Tungsten Tiled Z-Tip Points

The forged steel Z-tips are hard wearing in themselves, their working life is further enhanced with a tungsten leading edge and base.

The Disc

The discs are mounted in pairs on a bearing assembly which in turn is mounted on the disc bar. The disc bearing assemblies are internally sprung loaded to provide stone protection. The depth of the disc bar (and therefore discs) is centrally adjusted.

Frame

High gloss powder coated with edge primer to improve resistance to seed dressing and fertiliser.
Loading step platform and lighting kit as standard.

Hopper

400L or 1000L pressurised hopper with sealed lid.

Discs, Disc Bar and Suspension

The 380mm boron steal opening discs are mounted in pairs on a sprung axle for stone protection. The disc bar has a central adjuster to allow the disc depth to be adjusted according to conditions. The leading disc cuts through trash and crop residue as well as creating a slot to reduce soil disturbance from the tine coulter.

Depth Wheel & Adjuster

Simple depth wheels with an adjuster handle are used to set the working depth of the drill along with the top link to ensure the machine is level.

Chain Covering Harrow

Simple and yet very effective. The heavy chain covering harrow may look like a crude solution but is extremely effective at filling and closing the seed slot, albeit not too tightly so that the germinating seedling can emerge.
