Tined weeder AEROSTAR-CLASSIC

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 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.

Hard plastic protection at the connection between the tine section and its holders prevents wear of the steel components and ensures that they do not harm each other. They also ensure good guidance of the tine section, while still allowing adjustment to the terrain.

Due to the solid and accurate 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 making the frame swing. In addition, the frame is designed to withstand heavy loads and many seasons of operation 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 P-BOX-STI or P-BOX-MD seeding boxes can be mounted on all tined weeders. In addition to various additional options for the seed drill, steps for filling are available.

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. This tine is the first choice in small grain farming.

The aggressiveness of the spring tines can be adjusted with a central lever per section in five different positions. The positions can vary from dragging to “tip forward of the bend”. A hydraulic adjustment of the tine position is also available.

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

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 (except 18 m / 59.1 ft machines). Machines with a working width of 4.5 m / 14.8 ft to 9 m / 29.5 ft, the side wings of the mainframe are folded upwards for transport. 9 m / 29.5 ft machines can be equipped with a double-fold system and a heavy-duty construction, from 12 m / 39.4 ft this is standard. On all versions a hitching very closely to the tractor is ensured.

The ball-bearing mounted support wheels are adjustable in height in a half-breadboard. As an option the wheel base of the support wheels is infinitely variable up to 2.15 m / 7.1 ft. The support wheels take over the depth control and prevent the spring tines from penetrating too deeply in light soil conditions. The AEROSTAR therefore adapts perfectly to uneven ground.

• Tine 380 mm / 15“ long, Ø 6,5 mm / 0.26“
  The tine with a diameter of 6.5 mm / 0.26“ and a length of 380 mm / 15“ is particularly suitable for medium soil.
• Tine 490 mm / 19.3” long, Ø 6,5 mm / 0.26“
  The tine with a diameter of 6.5 mm / 0.26“ and a length of 490 mm / 19.3“ is designed for very light soil conditions.
• Tine 600 mm / 23.6“ long, Ø 7 mm / 0.28“ mm
  This tine (standard for AEROSTAR-EXACT) with a diameter of 7 mm / 0.28“ and a length of 600 mm / 23.6“ is well suited for special crops. Due to its length it can also compensate uneven soil conditions in the field very well.
• Tine 490 mm / 19.3“ long, Ø 8 mm / 0.31“
  For tough soil conditions the tine with a diameter of 8 mm /0.31“ and a length of 490 mm / 19.3“ should be used. This tine is the most commonly used in grassland cultivation.
• Tine 490 mm / 19.3” long STRAIGHT, Ø 8 mm / 0.31”
  For rocky soil we recommend this straight tine so that the rocks are not moved to the surface. It has a diameter of 8 mm / 0.31“ and a length of 490 mm / 19.3“.

The AEROSTAR-CLASSIC tined weeder can be equipped with hydraulic tine adjustment. The hydraulic tine adjustment ensures equal aggressivity over the full working widht in changing soil conditions and uneven fields. It is a preliminary stage to the AEROSTAR-EXACT, which is designed for special crops (and e.g. blind weeding).

The hydraulic tine adjustment ensures fast and convenient folding to the transport position (especially for model 450, 510, 750, 810 and 1350).

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.

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