Pneumatic Seeder P-BOX-STI
The pneumatic seeding box P-BOX-STI provides adjustment of the seeding rate depending on the actual working speed, as well as the electrical control unit "SPEED-TRONIC". The power-supply comes from the 3-pin plug of the tractor. Machines with 3 m and 6 m working width come standard with a 300 l tank. The seed box is equipped with a stirring shaft and a separate section on the seeding roller for each hose.

Tines 490mm/19.3“ long, Ø 10 mm/0.39“
For heavily felted grassland or in medium to heavy soil conditions, theses tines with a diameter of 10 mm/0.39“ and a length of 490 mm/19.3“ should be used. These tines are ideal to fight rough stalked meadow grass in summer.

Tines 490 mm/19.3“ long STRAIGHT, Ø 10 mm/0.39“
For stony soil these tines should be used. In order not to bring stones to the surface, we recommend the straight tines with a diameter of 10 mm/0.39“ and a length of 490/19.3“ mm. Tines adjusted “dragging“ protect the turf in wet or boggy grassland.

Heavy front levelling plante for perfect levelling of mole hills
A heavy triangular levelling plate in front of the support wheels levels out the mole hills. The soil is distributed evenly on the surface, there is no reconsolidation of the ground and the pores of the soil remain open.

Hydraulic pressure regulation
The hydraulic pressure on the parallelograms can be adjusted from the cab via the tractor's hydraulic system. This means that the tine pressure can be easily increased or reduced depending on the soil conditions. The tine aggresivity is identical on each section over the full working
width. The turf is opened - this helps to control the rough stalked meadow grass in summer. The hydraulic levelling system guarantees an equal pressure on each weeder section and the tines to follow the contour of the ground perfectly even in uneven terrain.

Parallelogram-guided weeder sections
The hydraulic levelling system with parallelograms works very smoothly even when working with high working speed. The weeder sections are always parallel to the ground so all tines exert the same downwards pressure.

No rollers
To combine grassland weeder and rollers in one machine does not provide the desired effect. The centrally placed deflector plates ensure an even distribution of the seeds over the full working width. Furthermore, the operating speed of roller and grassland harrow do not match. In case soil gets stuck to the roller, seeds which have been distributed by the weeder get stuck on it and previously sown grass is collected from the ground again. In addition, a roller etablishes contact between previously torn out weeds (such as the rough stalked meadow grass) and the ground. So they will not dry out, but continue to grow. Especially for reseeding and grassland care, rolling is not necessary as the roller runs on the turf and has very limited contact to the soil. For new seeding rolling can be beneficial, but it should be done in a separate operation after weeds dried out and with the optimal working speed for rolling.

Deflector plates are mounted centrally on the tine sections
The deflector plates with splash-guard are placed in the centre of each tine section. They spread the seeds before the last two rows of tine sections to establish optimal seed to soil contact.

Ideal adjustment of the frame to follow the contour of the ground
The joints are equipped with hardened bolts with 35 mm Ø and brass bushings which can be greased. The position of the stop bars change the setup of the frame - either it is rigid or the side wings can go down to copy the contour of the surface even better. Not only the tine sections, but also the heavy levelling boards can follow the surface of the ground.

Exact line spacing of the tines of 2.5 cm / 1”
The line spacing of exact 2.5 cm / 1” has a significant influence on the effect and quality of the operation. Tine fields with 6-rows with 60 tines on 1.5 m / 4.9 ft fields ensure an effective and efficient weed control. A bigger distance between the tines will leave unworked strips where weeds will continue to grow and the turf will not be dethatched.

Exact tine position and movement of the directly suspended springtines
The harrow tines are mounted to the harrow sections by plastic tine holders to ensure an exact tine position in driving direction. The spring coil of the tine is mounted below the tine holder to ensure free movement and vibration of the tine. In addition, the tines clean themselves due to the constant movement. A breakage of the tine is almost impossible, because the movement of the tine is not limited or restricted.

Tines position adjustable with a lever per section
The aggressivity of the spring tines can be adjusted with a central lever per section in five different positions. The position can vary from dragging to “tip forward of the bend”.

"SPEED-TRONIC" Terminal 
The PNEUMATICSTAR-PRO-STI grassland seeder is equipped with the pneumatic box P-BOX-STI. The user-friendly "SPEED-TRONIC" terminal regulates the sowing rate depending on the actual forward speed. The SPEED-TRONIC control unit with electrical quantity adjustment is very easy to use. The necessary speed information can be obtained via various sensors or via the 7-pole signal socket of the tractor.

PNEUMATICSTAR-PRO 1200

The PNEUMATICSTAR-PRO 1200 is designed for large-scale farms. The chassis, which is attached to the lower links of the tractor's 3-point hitch, is carried by two large dimensioned wheels. During operation six additional support wheels on the side-wings ensure optimal guidance of the machine in the field. A stable sectional steel tube frame with cross braces ensures smooth operation of the machine, preventing the frame from swinging forward or backward.

Like the PNEUMATICSTAR-STI, the PNEUMATICSTAR-PRO-STI also uses the SPEEDTRONIC control unit. The seeding roller is also driven electrically. The machine has 3, 6 or 12 meter working with and a extremely solid construction. A heavy levelling board which is overload-protected by springs, levels molehills in front of the support wheels. It is adjusted “on hold”, which lifts the soil and spreads it loose in the turf. Pores in the soil are not smeared up!

As the support wheels are behind the levelling plate the machine works very smoothly with a high working speed.
