Great flexibility of use
Possible use for grassland reseeding or new seeding (1) or underseeding e.g. in cereals (2), corn (3) etc.

Perfect for under- or reseeding
The pneumatic seeders with integrated stirring-shaft are designed in such a way that each sowing tube has its own seeding wheel section to achieve perfect dosing and uniform output.

Hydraulic tine adjustment – perfect in changing soil conditions
The hydraulic tine adjustment makes adjustment to the GRASS-MANAGER in changing soil conditions easier. Furthermore, folding to the transport position is more convenient as you can easily put the tines into a flat position. The hydraulic tine adjustment can be retrofitted any time.

Increased vibration-effect due to special tine holder

Electrical quantity dosage
The grassland seeder PNEUMATICSTAR-STI is equipped with the pneumatic seeder P-BOX-STI as standard. The P-BOX-STI is a pneumatic airseeder with electrical adjustment of the seeding amount. The user-friendly SPEED-TRONIC control unit regulates the seed quantity depending on the actual working speed. The necessary speed info can be obtained via several sensors or via the 7-pole signal plug of the tractor.

Tine 490 mm / 19.3” long, Ø 7 mm 0.28 “
This standard universal tine with a diameter of 7 mm / 0.28“ and a length of 490 mm / 19.3“ is ideal for medium to heavy soil conditions. This tine length can also compensate uneven spots in the field.

Area specific seeding with the ""ProActive Sensor from Isaria"
To be able to adjust the seeding rate specifically to certain sub-areas (e.g. for grassland reseeding), the STI control is compatible with Isaria's ProActive Sensor. The two sensor heads of the ISARIA ProActive sensor system are integrated in the frame on the front hitch of the tractor. They detect and analyse the crop; on this basis the correct seeding rate for the respective area is precisely determined and adjusted by the STI terminal of the seeding unit.
 

No rollers
To combine grassland weeders and rollers in one machine does not provide the desired effect. Even distribution of the seeds over the entire working width, which is ensured by the centrally placed deflector plates, is the key factor for good emergence of the seeds. Furthermore, the operating speed of roller and grassland weeders 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 establishes 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.

Rubber support wheels for gently work
Depending on the working width, the GRASS-MANAGER series and the PNEUMATICSTAR series are guided by two or four rubber support wheels. The support wheels prevent the tines from working too deeply in light soil conditions. They are height-adjustable in the half-hole grid.
 

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.

Levelling plate for excellent distribution and levelling of molehills
In front of the weeder sections a levelling plate can be mounted, which is overload-protected by a leaf spring. This levelling plate is height adjustable and ensures an excellent distribution and levelling of molehills. In addition, it distributes and levels manure and slurry. (Only up to 6 m working width and for 900 SR and 1200 SR, not in combination with hydraulic tine adjustment)
 

Stop bar for perfect adoption to the surface
By taking away or demounting the stop bar on the wing (only on machines without shear folding) the machine follows the contours of the land surface perfectly.
 

Exact line spacing of the tines of 2.5cm / 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 aerated.

Tines 490mm/19.3“ long, Ø 10 mm/0.39“ instead of standard tine
(only available for heavy frame SR)
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 meadow-grass in summer. The following reseeding indicates an increase in basic feed quality.
 

Transportation lock with a rope pull
The transportation lock is unlocked via a rope pull (only on machines without shear folding).
 

Stable operation
Due to the solid and strong frame construction the operation of machine and frame is very steady, even in higher working speeds. Also on hard soil the tined weeder can apply sufficient pressure on the tines without making the frame swing. In addition, the frame is designed to withstand heavy loads and many seasons of operation without any problems.

tine 490 mm/19.3“ long, Ø 8 mm/0.31“
In middle or heavy soil, the tines with 8 mm (0.31”) diameter and 490 mm (19.3”) length should be used. These tines are the most common ones in grassland care.
 

Plastic support on U-frame
On the U-frame holding the weeder sections the supports guiding the section are covered with hard plastic. This prevents the U-frame from wearing.
 

Exact tine position and movement
The tines are fixed against rotation by sturdy plastic holders on the tine fields. This guarantees a tine that is aligned exactly in the working direction. The  spring of the tine is mounted freely below the tine holder. This improves the vibration of the tine and guarantees the movement of the tine by the spring. A breaking of the tine is almost excluded since the movement of the tine is not limited.
 

tine 490 mm/13.9” long STRAIGHT, Ø 8 mm/0.31”
For stony soil, in order not to bring stones to the surface, we recommend the straight tines with a diameter of 8 mm (0.31”) and a length of 490 mm (19.3”). Tines adjusted “dragging“ protect the turf in wet grassland.
 

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

Warning signs with LED-lights
For this grassland seeder warning signs are also available for the front and rear. (Symbol image - options vary depending on the design).

Guaranteed equal tine aggressivity over the entire working width

The tine tube is torsion-resistant and guarantees the same tine position and the same tine aggressivity over the entire frame length. This is particularly important in hard soil conditions.

Compact Retraction
Even machines with a working width of 12 m / 39.4 ft and 15 m / 49.2 ft can be folded to a transport width of only 3 m / 9.8 ft. Machines with a working width of 4.5 to 9 m the side wings of the main frame are folded upwards for transport. 9 m machines can be equipped with a double-fold system and a heavy-duty construction, from 12 m this is standard. On all versions a hitching very closely to the tractor is ensured.

Stronger construction from 9 m working width
A larger working width means greater forces acting on a machine. The triangular bracing on machines with double folding prevents the side wings from swinging and jumping even at higher working speeds. The tine aggressivity can be adjusted depending on the conditions.
