Rotative weeder
AEROSTAR-ROTATION

• Weeding when there is a lot of organic material, e.g. in mulch seeding
• Early weeding when soil moisture is present without “smearing” the soil
• Aggressive crust breaking and gentle weeding – quickly adjustable via the working speed as well as hydraulic aggressivity adjustment
• Self-cleaning through rotating working tools – rolling instead of “sweeping” weeding

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.

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.

Due to a tine pressure of up to 22 kg / 49 lbs per tine, it is possible to break up heavy soil crusts. The more aggressively you weed, the slower you should drive.

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.

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.

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

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. 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.

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.

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.

The angle of the inclinantion of the star wheels is mirror-inverted on half of the machine to prevent a possible side pull.

A double star-wheel for full-surface working is mounted as standard for the middle area.

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.

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.

Transport lock is standard equipment on all machines. All machines up to 6 m / 19.7 ft. by a hydr. locking block on the cylinder and machines bigger than 9 m / 29.5 ft (picture). with a hydraulic transport lock on the side wings. This provides additional safety when driving on the road or when the machine is parked.

Three different pneumatic seeders are optionally available to seed catch or cover crops, undersown crops or small seeds. The P-BOX-STI is electrically driven, the P-BOX-MD mechanically (each with plastic or steel tank) or the front tank JUMBO-SEED also electrically.

These are available to the front as well as to the rear.
