Avant mounted seed drill combination with FTender mounted front hopper

Implements with working widths from 3 m to 4.5 m are equipped with a segmented distributor head directly above the coulters. The optional mechanical half-side shut-off
of the segmented distributor head enables easy implementation of asymmetrical tramline rhythms, for example by shutting off one side during the first pass, with a sowing width of 3 m and a simultaneous tramline width of 24 m. 

The benefits:

• Short conveying times for the seed
• Reduction in overlap saves seed
• Minimising dust creation inside the seed hopper because no seed is rerouted

The electric half-side shut-off for the Avant 5002-2 and 6002-2 can be carried out remotely from the tractor cab or, mechanically, directly on the FTender mounted front hopper. The feed into one of the two segmented distributor heads can be prevented via a flap directly below the metering unit, so that half-side shut-off can be implemented. 

The electric half-side shut-off helps to reduce excess sowing on the headland or at the edge of the field and to save seed. Half-side shut-off enables the
machine to be comfortably switched off via the terminal in wedge shaped fields or steeply angled headlands. Additionally, via GPS, automated switching of half the working width is possible.

With the aid of the tramline shut-offs, in total up to six seed rows per side can be switched off. The wider tramlines are ideal when using crop care tractors with tyre widths of up to 1,050 mm on 15 cm row spacing or 875 mm on 12.5 cm row spacing. The seed rate is automatically reduced when the tramlines are shut off.

The maintenance-free RoTeC single disc coulter

Goes right to the limit of practical operation and placement

RoTeC coulters are maintenance-free and work very reliably, even where large amounts of straw and plant residues prevail. The sowing disc and furrow former create the seed furrow profile and provide the optimum seed placement into the soil. The Control 10 depth guidance disc, or the Control 25 depth guidance roller, prevent the soil from sticking to the sowing disc, thereby ensuring that the pre-selected sowing depth is precisely maintained.

Row spacings of 12.5 cm and 15 cm can be chosen.

Advantages of the RoTeC coulter

• High-performance single disc coulter for wet and cohesive soil types
• High level of self-cleaning through the depth guidance roller
• Decoupling of coulter guidance and reconsolidation
• Coulter pressure of up to 35 kg

1.    Precise working depth adjustment from 1 to 6 cm.
2.    Reinforced support arm with a coulter pressure of up to 35 kg. Central coulter pressure adjustment.
3.    Control 10 depth guidance disc or Control 25 depth guidance roller for consistent sowing depth control. The depth control element actively cleans the sowing disc during use.
4.    Furrow former for a clean profile seed furrow.
5.    Seed guide tube up to the furrow former for an even seed placement.
6.    Sowing disc ∅ 320 mm, made of boron steel, working angle of 7° for smooth operation of the coulter.
7.    Exact harrow for excellent seed coverage.

One of the unbeatable advantages of the RoTeC coulter is that there is no connection between depth control and the reconsolidation system. This means that the coulter is raised only once when going over a stone. Furthermore, the coulter pressure and harrow pressure can be adjusted independently of one another. This very even and accurately controlled way of guiding the RoTeC coulter is provided by the Control 10 depth guidance disc with a 10 mm wide contact area or the Control 25 depth guidance roller with a 25 mm wide contact area mounted directly beside the coulter.

The basic setting of the sowing depth is in 3 steps and is done directly on the coulter without tools.

Precise, simple adjustment of the sowing depth in 3 steps

RoTeC coulters operate with a coulter pressure of up to 35 kg. In this case, the actual effective coulter pressure is comparatively higher with AMAZONE, because the pressure is not split between the coulter and the following press roller, but acts solely on the coulter - the harrow pressure is adjusted and applied separately. Working with less coulter pressure is possible without any problem when sowing rape or when early sowing in dry conditions.

Overview of the maintenance-free TwinTeC double disc coulter

Advantages of the double disc coulter:

• Extremely precise seed placement thanks to the extremely smooth and clean running of the double disc coulter
• Consistent sowing depth thanks to the high constant coulter pressure of up to 60 kg
• Optimum contour following due to the coulter guidance in the parallelogram
• Simple central seed depth adjustment
• Effective sowing even under difficult conditions thanks to a high through passage and low angle of attack of the discs

1. Adjustable harrow: the angle of attack is adjusted according to the degree of straw residues present.
2. Perfect parallelogram with the top link for infinitely variable and precise adjustment of the sowing depth from 0 to 6 cm.
3. Centralised, 100% independent adjustment of the placement depth and coulter pressure.
4. TwinTeC coulters mounted on rubber elements for shock absorption and central adaptation of the coulter pressure from 0 to 60 kg.
5. Protective front plate
6. Removable shims to compensate for disc wear.
7. Discs fastened at 5 points with recessed Torx screws. No wear on the fixing discs.
8. Maintenance-free bearings. No lubrication points for the maintenance-free coulter.
9. Double disc ∅ 340 mm, angle of 10°, row spacing 15 cm. 
10. Internal scraper – as an HD variant.
11. Depth control and press rollers with 50 or 65 mm width (scrapers optional).

The sowing depth of the TwinTeC double disc coulter can be centrally adjusted on the coulter frame. A depth guidance roller behind each TwinTeC coulter provides precise depth guidance, thereby ensuring that the placement depth of each individual TwinTeC coulter is maintained. Thanks to the large coulter clearance of 195 mm and the linkage to the depth guidance roller via the top guided roller carrier, sufficient space remains, meaning that blockage-free operation is possible. Due to the narrow angle of attack of the sowing discs of 10°, excellent material passage is ensured even at high speed and with large amounts of harvest residues. There is a choice of two different depth guidance rollers. The Control 50 mm depth guidance roller has a high through passage and is ideal for heavy, hard soils. On the other hand, the Control 65 mm depth guidance roller offers a higher carrying capacity, which is ideal for lighter soil types.

The Avant seed rail for sowing cereals can be easily dismantled. Instead, a PreTeC seed rail with 6 sowing units can be attached to the KE 4502-2-300 Rotamix, and a PreTeC seed rail with 8 sowing units can be attached to the KG 6002-2. This makes it easy to switch between sowing cereals and single seed sowing.

Each TwinTeC coulter can be optionally equipped with a directly mounted harrow. The coulter harrow provides additional loose soil on top of the seed furrow.

The benefits:

• Depth guidance with sprung harrow carrier
• Adjustable in 7 steps up to 150 mm 
• Adjustable intensity in 3 stages: 30 degrees, 45 degrees or 60 degrees

Since all the coulters are suspended in a parallel guided frame, central and stepless adjustment of the coulter pressure is possible. It is possible, for instance, in the area behind the tractor wheels, to increase the coulter pressure by another 6 kg using additional tension springs.

The hydraulic coulter pressure adjustment enables the coulter pressure to be comfortably adjusted from the tractor cab. The coulter can also be lifted by up to 145 mm. The coulter lift is an extremely useful option for working in field corners.

KX Cultimix and KG Cultimix rotary cultivators

Advantages of the rotary cultivator:

• Tines “on-grip” ensure a constant working depth, even on heavy ground
• De-mixing effect of the tines ensures optimum germination conditions for the seed
• Spacious clearance between the tines and above the tine carriers – ideal for extreme amounts of straw
• With the Long-Life-Drive system for extreme loads and a long service life
• With the Quick + Safe-System – the proven quick tine change system and integrated stone release
• Robust design as the tine carrier and shaft are forged from one piece
• Comfortable adjustment via the universal setting tool
• Easy adjustment of the levelling board. No readjustment required when changing the working depth of the soil tillage system

• Trailing tines

Tine quick change system

The tines are simply pushed into the sockets of the tine carrier and secured with a lynch pin. It couldn’t be easier or quicker. There are no tine fixing bolts that require retightening. Converting the tines from “on-grip” to trailing is also quick and easy. The tines are forged from special hardened steel and are yet elastic and extremely wear-resistant.

Integrated stone protection

The sprung tine fixing system allows the tines to yield when stones are encountered. The tines are firmly clamped in the socket through the centre of the tine carrier. This socket becomes wider towards the outside, so that the horizontal part of the tine can twist out of position. Much of the shock is thus absorbed when the tip of the tine hits a stone. This tine fixing system ensures reliable operation in stony soils enabling the tines to be used "on-grip" on the KX Cultimix and the KG Cultimix.

Short changeover times between each field increase profitability.

Moving from one field to the next is quick and easy: Fold in hydraulically, drive to the next field, fold out and start work! The machine is folded out from a transport width of 3 m to a working width of, for instance, 6 m within a few seconds.
 

CombiDisc system – the disc harrow

The discs of the CombiDisc compact disc harrow, with a diameter of 410 mm, intensively incorporate organic matter 
at working depths of 3 to 8 cm.

Thanks to the small disc diameter, a high peripheral disc speed is achieved, ensuring a very good crumbling effect. Especially on light to medium soils, the CombiDisc, in combination with a rear roller from the extensive packer range ensures the optimum seedbed. 

The KE Rotamix rotary harrow, available in working widths from 3 to 6 m, features a more compact design of the rotary harrow trough with 4 tool carriers per metre of working width.

The trailing tines produce an excellent crumb structure and level the soil surface perfectly. The KE Rotamix rotary harrows are particularly suited to seedbed preparation on heavy soils and after the plough.

The rotary cultivator or rotary harrow and the Avant seed rail can be very easily separated to allow the soil tillage tool to be flexibly used elsewhere. All the rigid executions of the KE Rotamix, KX/KG Cultimix, and CombiDisc models in working widths of up to 4 m can be converted for solo use in just a few minutes thanks to QuickLink. The folding models, in working widths of 4 m or more, can be dismantled manually in around 30 minutes.

Roller range

To complete the seedbed, the loose soil is reconsolidated. This ensures better soil contact for the placed seed and smoother running of the coulters. The result is even greater precision.

With a large diameter of 500 to 600 mm, AMAZONE packers run much more smoothly and with less ground pressure than smaller rollers. Enclosed rollers, such as the wedge ring or and wedge ring with Matrix tyre profile are used on loose and light soil, as these provide better support than open rollers.

Structure of a wedge ring roller
1. Air cushion 
2. Metal insert in the rubber to increase rigidity
3. Spacer ring with dirt-repellent surface

Reconsolidating in strips just in the actual seeding zone allows the seed to be connected to the ground water found deeper without bringing the full capillary effect up to the soil surface. This ensures that the seedling is supplied with water (1) without any evaporation on the surface (2). The soil is not dried out unnecessarily. This ensures good germination, even under dry conditions.

In wet conditions, however, the unconsolidated strips between the seed rows allow water to infiltrate down deeper (3). This enables an adequate gaseous exchange (4) – vital oxygen can reach the young roots, even as they grow deeper into the soil. The best conditions for good germination and successful seedling development of the crops.
 

The PW tooth packer roller has a good self-driving effect and, with its leading teeth, offers a good reconsolidation across the entire surface. The tooth packer roller is extremely versatile due to these features. 

• Complete reconsolidation over the entire soil surface
• Runs blockage-free on sticky soils and where there is a lot of straw
• As standard with hard metal coated, wear resistant scrapers
• Low-mounted scrapers ensure a smooth surface even in wet soil conditions

With its trapezium rings, the TRW trapezium roller provides reconsolidation in strips. Due to its good carrying ability, the trapezium rings are prevented from sinking in too deep on light soils. 

• Good carrying capability
• Produces a lot of fine soil
• As standard with hard metal coated, wear resistant scrapers

The KW wedge ring roller has a wide range of applications. Its design ensures reconsolidation in strips in almost all soils under any conditions. There is no chance of sticking, capping or blocking up.

• Universal for all soils and conditions 
• Strip-wise reconsolidation
• Even in heavy soils, sufficient loose earth is available for optimum seed coverage 
• Smooth coulter travel due to the pre-formed seed furrow

The KWM wedge ring roller, with its Matrix tyre profile offers a particularly good self-driving effect. The roller produces more fine soil for the seedbed due to the Matrix profile.

• Strip-wise reconsolidation 
• Improved crumbling even under tough conditions 
• Smooth coulter travel due to the pre-formed seed furrow
• Very well suited to any weather, no matter whether wet or dry
