Precision tined weeder AEROSTAR-EXACT

The AEROSTAR-CLASSIC & -EXACT is equipped with direct spring-loaded tines.

These have many advantages:

• Tines swivel – ensuring effective weed control also in the row without harming the crop
• Highest adjustment range of the tine pressure on the market – enables gentle blind weeding and aggressive crust breaking
• Vibration ensures self-cleaning of tines – guarantees operation without clogging
• Weeds are uprooted from soil and dirt – fast drying out prevents re-growth
• State of the art tine guidance system – ensures weed control over the full surface

The tine position is adjustable from the tractor via the centrally controlled and sensitive hydraulic section adjustment. This system also provides hydraulic pressure and level compensation of all the tine sections of the machine. The hydraulic tine adjustment facilitates the use of the tined weeder AEROSTAR-EXACT in changing soil conditions. When folding to the transport position, the tines can be adjusted to the flattest position very comfortably. The hydraulic pressure compensation ensures that the tines operate with equal aggressivity over the entire working width.

Due to the precise depth control of the AEROSTAR-EXACT via support wheels at the rear and in the front (which are adjustable in a half-breadboard) it is perfectly suited for blind weeding. The pendular axle and the pivoting rear wheels ensure perfect ground adaptation. Sensitively adjustable tine pressure by the hydraulic tine adjustment guarantees precise depth guidance of the tines, particularly on uneven ground.

The line spacing has a decisive influence on the working effect and quality of the operation. With a 6-row arrangement of 60 tines per 1.5 m / 59.1″ field, an effective line spacing of 2.5 cm / 1″ is achieved. The basic requirement for efficient weed control is the smallest possible line spacing.

The tines on the weeder are fixed to the sections by plastic holders to prevent them from twisting so the tine is aligned in the exactly working direction. The spring coil of the tine is mounted below the holder to ensure free tine movement and vibration out of the spring coil. As movement of the tine is not limited or restricted, breakage is very unlikely.

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

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 (up to 55 cm / 21.7″ – depending on tine position and length).

The AEROSTAR-EXACT is perfectly suited for a late weeding, for sensitive special crops or for combing out of coachweed (vine-like parasitic weed).

The precision tined weeder AEROSTAR-EXACT is equipped with 600 mm / 23.6″ long and 7 mm / 0.28″ thick cranked spring tines that adapt perfectly to uneven soil. They allow weeding operations even at late stages of the crop’s development. These tines have also proved their worth in special crops, as longer tines can adapt even better to uneven soil!

All support wheels are fitted with a tractor tyre profile what cleans them easier and ensures a tidy operation. In addition, this profile leaves a rough surface and does not press the soil firmly. Thus, the following weeder tines of the rear support wheels can work better and the soil is worked through completely. For larger working widths, the wheels on the wings are automatically swivelled in during the folding process, so there’s no need to leave the cab.

The pivoting support wheels at the rear of the machine ensure that the tined weeder runs smoothly (especially at high speeds), even on bends. Track tines are mounted as standard behind the support wheels.

The sections are mounted on forks without clearance. This guarantees the machine works exactly in the set working depth. The sections can not turn and twist (for example when driving in tractor tracks) and are running very smoothly.

A slot for the upper link allows the AEROSTAR-EXACT to perfectly compensate uneven soil conditions in driving direction.

The ball-bearing mounted support wheels are adjustable in height in a half-breadboard. The wheel base of the support wheels is infinitely variable up to 2.25 m / 7.40 ft. The support wheels take over the depth control and prevent the spring tines from penetrating too deeply in light soil conditions. The AEROSTAR-EXACT therefore adapts perfectly to uneven ground.

Transport lock is standard equipment on all machines. All machines up to 7,5 m / 24.6 ft. by a locking bar on the cylinder and machines bigger than 9 m / 29.5 ft. with a hydraulic transport lock on the side wings. This provides additional safety when driving on the road or when the machine is parked.

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

Three different pneumatic seeding boxes 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.
