Mechanical seed drills

The wide access grille is sturdy and easily reached via the steps. The filling height is less than 70 cm above the access grille. The handrail provides safety when standing.

The large opening angle of the cover makes it easy to fill the hopper, even with big bags.

The inside of the seed hopper is designed to ensure an optimal, continuous flow of seeds.

The on-board computer can be fitted with an optical and acoustic seed level alert upon request. The sensor in the hopper is easy to adjust and reliably detects the seed quantity currently remaining in the hopper.

The Saphir features a hexagonal seeding shaft with quick-change system. Changing the seed wheels is very easy. Besides the combination seed wheels Conti Plus there are two single-part seed wheelsavailable:

• Mono Plus for small peas up to 150 kg/ha
• Mega Plus for peas and beans above 150 kg/ha.

The large seed wheel component is designed as a fluted cellular rotor of the two-part Conti Plus combination seed wheel. It continuously feeds the seeds into the seed pipes. Large seeds are metered out precisely and consistently. The cam wheel on the side meters out very small seeds such as rapeseed precisely and consistently. The separately driven seed wheels can be easily activated and deactivated.

A further seed wheel without a lateral cam wheel is available under the designation Conti Plus S for cereals with low sowing rates, hybrid cereals and fine seeds with a sowing rate of up to 100 kg/ha

The functionally designed seed wheel housing is made out of robust, low-wear plastic. The shut-off gate and bottom gates can be adjusted quickly and easily without the need for tools. The discharge flap integrated into the seed wheel housing can be easily converted from seeding to calibration mode.

Calibration testing is done quickly and easily, as seeds are collected in two calibration trays. These are inserted into and removed from the machine via convenient pull-outs on the side. Seeds flow directly into the container for weighing through flaps on the side.

The proven parallelogram-guided double disc coulters with depth control wheel ensure precise seed placement and uniform field emergence.

More about the double disc coulter

The seed depth of the double disc coulter can be adjusted continuously via a screw in the centre of the seed drill. Turning the robust coulter frame changes the position of the pressure wheel relative to the double disc coulter – and with it the seed depth.  Separately adjusting the seed depth and coulter pressure ensures precise seed placement, especially on changeable soils.

The tramline mechanism allows tramlines to be created at various intervals. To do this, the respective seed wheels are activated and deactivated via gear wheels and a clutch. The gear wheels on the intermediate shaft can be moved as required, making it very easy to set the various track widths. The tramline width can also be adjusted to the tyre width via additional gear wheels.

The Saphir mechanical seed drill is usually mounted on the roller of the Zirkon power harrow. The complete seed drill is carried directly by the roller. This makes it easier for the power harrow to avoid obstacles.

Optionally the Saphir can be both lifted and swung towards the front via a hydraulic cylinder. This alleviates the load reduction on the front axle. The hydraulic cylinders can additionally be used to individually adjust the position of the basic frame relative to the coulter bar by means of Hydro-Clips.
