Clogging-free weeding in organic matter or mulch-till
Due to the rotating stars the machine can handle a big amount of organic matter (in mulch-till fields or in fields with heavy weed infestation) without clogging.

Hydraulic adjustment of aggressivity
The pressure is comfortably and infinitely adjustable from the tractor´s
seat. This innovative system uses the power of two counteracting tension
springs. By extending the hydraulic cylinder, the tension of the preload spring
increases. The pressure on the star wheels increases as well. When retracting the
cylinder, the relieving spring is tensioned. If desired the pressure on the star
wheels can be reduced, until absolutely no down pressure is left (the star wheels
are nearly floating).

Kindly note: You need experience and knowledge to choose the right aggressivity and working speed for the crop.

Special mounting of the star wheels
In order to compensate sideforces, the stars are mounted bi-directional (line spacing 15 cm / 5.9")
Hydraulic adjustment of agressivity - possibility to push down (increase aggressivity) or lift the section (work with less than the dead weight of each arm / star), with position indicator
Hydraulic pressure and level compensation of the sections for best adaption to the soil surface
Position indicator of the pressure and level compensation
Diameter of the star wheel 500 mm, tine diameter 6,5 mm
Maintenance free bearing of the star wheels
Working speed up to 10 km/h

The photos and images show possible variants and some special versions. The factual machine configuration may differ from these illustrations.

Improved breaking of soil crusts
Due to a tine pressure of up to 22 kg per tine, it is possible to break up heavy soil crusts. The more aggressively you weed, the slower you should drive.

Maintenance free bearing of the star wheels
The bearings of the stars are maintenance-free and durable. Therefore they remain without clearance even after many seasons and hectares in the field.

Pressure on the rotating star wheels can be hydraulically reduced
When working in sensitive crops and light soils the pressure on the rotating star wheels can be hydraulically reduced, until there is no downpressure anymore and the star wheels are floating. When downpressure is minimized, the soil has to be very even for optimum performance.

Early weeding even in humid soil
In contrast to the common tine weeder, the Aerostar-Rotation can already be used even if the soil is still moist. This way the rotative weeder has an increased time of application in comparison to the standard tined weeder. This is a great advantage in changing weather conditions.

Effective also in a late growth stage
An effective use of the machine is also possible in a late stage of growth, because the rotating wheel does not pull any plants, they simply pass through. The inclined position of the star wheels improves the weeding-effect in the row. Weeds are "swiped out" of the row as long as they are not too well established.

Inclined mounted star wheels
The inclined mounting of the star wheels ensures that the weeder cleanes itself from residue and it has an important effect on the aggressivity of operation. The faster you drive, the more aggressive the rotative weeder works. The more aggressive the setting, the slower you should drive.

Stable operation
Due to the solid and strong frame construction the operation of the machine and frame is very steady, even at higher working speeds. In addition, the frame is designed to withstand heavy loads and many seasons of work without any problems.

Large frame clearance
A large frame clearance is guaranteed by the position of the sections and the frame. This ensures operation without damaging the crop even when the plants are higher.

Simple mounting of a seeding box
The P-BOX-STI or P-BOX-MD seeding boxes can be mounted on all tined weeders. In addition to various additional options for the seeding box, steps for filling are available.

Transport lock
Transport lock is standard equipment on all machines. All machines up to 6 m by a hydr. locking block on the cylinder and machines bigger than 9 m with a hydraulic transport lock on the side wings (picture). This provides additional safety when driving on the road or when the machine is parked.

Pneumatic seeding box
Two different pneumatic seeding boxes are available for easy distribution of cover crops or for re-seeding. The P-BOX-STI with electric drive (picture) or P-BOX-MD with mechanical drive (picture) of the seeding roller.

Bi-directional angle
The angle of the inclinantion of the star wheels is mirror-inverted on half of the machine to prevent a possible side pull.
Standard weeder tines are used in the center where there is no star wheel because of the mounting mentioned above. As an option there is a star-wheel-element available.

Diameter of the star wheel 500 mm - tine ø 6,5 mm
The work is done by 6.5 mm / 0.26" thick spring steel tines casted into a plastic disc. Each of these 500 mm / 9.7“ star wheels are suspended separately, therefore they adapt perfectly to any surface irregularities. In order to prevent the tines from falling out, they are casted in an u-form into the disc.

Line distance of 15 cm / 5.9“
The discs are mounted at a line distance of 15 cm / 5.9“ on sections of 1.50 m / 4.9 ft. Even at low working speed, as often required for sensitive crops, the AEROSTAR-ROTATION works effectively.

The rotative weeder AEROSTAR-ROTATION combines the advantages of a tined weeder and a rotary hoe. The result is a rotative weeder with a very wide range of applications. The work is carried out by steel pins which are embedded in a plastic disc set at an angle. The individually suspended, rotating working tools uproot and shed weeds, promote the tillage of yield crops and break up even hard soil incrustations without any problems. This method of working makes the AEROSTAR-ROTATION also very suitable for weeding in mulch sowing. With the hydraulic pressure adjustment the pre-tension of the star wheel carriers can be infinitely varied between relief and load from the tractor cab. The relief goes so far that the star wheels almost float. This makes the machine ideally suited for difficult soil conditions. In addition, this setting can be used to achieve precise blind weeding. The rotative weeder AEROSTAR-ROTATION, similar to the AEROSTAR-EXACT, can be used in almost all row, as well as drilled crops.
