Uncluttered view ahead and to the rear

Freie Sicht nach vorne und hinten

The front mounted seed hopper has been designed to be wide and low so as not to obstruct the driver’s view. The same applies to the visibility to the rear, where the lack of a seed hopper makes for an uncluttered view of the rear mounted implements.

Precise metering drive: Simple adjustment and comfortable calibration

Praeziser_Dosierantrieb

On the precise, mechanical metering drive, the star wheel, in conjunction with the Vario gearbox, ensures a consistent drive of the metering unit on the seed hopper.

Available as an option: electric seed rate adjustment via AmaTron 3.

The emptying of the seed in the hopper is quickly and simply done via the quick emptying device which is easily accessible and fitted onto the hopper.

For emptying any residual amounts, a slide is opened and the hopper contents emptied into the large calibration tray.

The cassettes of the seed metering system can easily be exchanges. This allows the precise and gentle metering of all seed types and seed rates with excellent distribution along the row even at high forward speeds.

As an option, the metering drive of the Avant can be regulated electrically via AmaTron 3. In conjunction with the electric drive, calibration is comfortable and fully automated. The electric drive also offers additional functions, such as, for instance, the pre-metering of the seed in field corners and the increase and decrease of the seed rate during operation.

Metering cassettes for any type of seed

Dosierwalzen

Special metering cassettes for different application rates precisely and gently deliver the seed up to the distributor head. The three metering cassettes supplied as standard cover up to 95 % of all seeds. Additional cassettes, for instance for maize or special crops, are also available.

The interchangeable metering cassettes are suitable for the following application rates: fine seeds (approx. < 15 kg/ha), medium sized seeds (approx. < 140 kg/ha), normal seeds (approx. > 140 kg/ha).

Hydraulic blower fan drive

Gebläse

A power-efficient hydraulic motor drives the blower fan for the seed delivery. Modern tractors are equipped with sufficient hydraulic valves which, independent of the engine speed, provide a constant oil flow and thus fulfil all the parameters for hydraulic drive.

The new high performance blower fan is characterised by its low oil requirement of just 25 l/min at 3,500 rpm and minimum noise emission.

Variable tramline control

Variable_Fahrgassenschaltung

The 6 m Avant features 2 distributor heads on which 2 x 6 seed rows per tramline can be closed. So, at a coulter spacing of 12.5 cm, 87.5 cm wide wheel tracks can be created.

On the 4 m and 5 m Avant, only one distributor head is used. With this distributor head, 2 x 4 seed rows can be closed off on each tramline, resulting in a wheel track of 62.5 cm.

In this way, AMAZONE takes into account the demands of wider and wider tyres on the crop husbandry tractor.

Translucent distributor head

Klarsichtverteilerkopf

The translucent distributor head ensures the permanent monitoring of the seed flow and therefore it is located outside the seed hopper within full view of the operator.

When creating tramlines, the amount of seed is reduced accordingly by the electric metering device. Seed delivery to the tramline coulters is interrupted as soon as the electric motor closes the relevant seed tubes in the distributor head.

Sowing following the plough or mulch sowing with pneumatic seed drill combinations

Pflug_und_Mulchsaat

AMAZONE seed drill combinations have proven themselves by the hundred thousand both for cost saving mulch sowing and also when conventionally sowing following the plough.

When mulch sowing, the combination of rotary cultivator, wedge ring roller and seed rail with RoTeC Control disc coulters is recommended. The rotary cultivator loosens even hard packed soils and maintains its working depth due to the “on-grip” tines. The straw is simultaneously incorporated and, thanks to the large clearances between the tines and the trough, the straw-soil-mixture can pass through the machine above the tine carriers without a problem. The following levelling board levels any ridges and furrows.

The wedge ring roller reconsolidates the soil in strips so that one third of the soil is reconsolidated whereas two thirds of the surface remains loose. The RoTeC Control coulters then precisely place the seed into the reconsolidated strips.

(1) Even in very dry weather the capillary water is drawn back to the seedling.

(2) Rain from heavy downpours simply drains into the unrolled, loose areas.

(3) Gaseous exchange in the loose soil – the roots can breathe.

Folding rotary cultivator in 4 m, 5 m or 6 m working widths

Klappbarer Kreiselgrubber Avant

The benefits:
Quick changeover times between individual fields further increases profitability.

Transferring from one field to the next is carried out quickly and simply: Just fold up hydraulically, drive on to the next field, unfold and start work!

The right working width for tractors of any power:
The 4 m, 5 m and 6 m working width rotary cultivators fold hydraulically to a transport width of 3 m and are suitable for tractors up to 265 kW (360 hp).

Especially in farm-overlapping situations or under frequently changing operational conditions, the correct tine rotation speed is quickly adjusted by selecting the right gear. This ensures the optimum quality of work in any conditions.

The compact design of the particularly robust folding rotary cultivator allows high output use even in smaller fields.

The main gearbox of the folding rotary cultivator is equipped with 2-speed lever change for rapid adjustment of the tine speed to different soils and working intensities.

Staggered tine layout guarantees smooth running

Werkzeugtraeger

With AMAZONE rotary cultivators, the tines are arranged in a specific offset position towards each other. This guarantees an even soil crumbling and a smoother machine running. Incidents of vibration and peak loading are thereby prevented. The machines suffer less stress, and the power and fuel requirement is reduced.

The “extreme” stone test track

Steinteststrecke

All AMAZONE soil tillage implements are subjected to extreme stresses, being continuously tested on the stone torture track. This is not only for newly developed machines but also as part of series production supervision, meaning they are well prepared for the extremely wide range of operating conditions encountered when in actual use. This makes sure that you have the maximum of reliability with all AMAZONE rotary harrows and rotary cultivators.

Long-Life-Drive – For all rotary cultivators: Quality within the system

Long_Live_Drive

Long-Life-Drive is the optimised drive system for all AMAZONE rotary harrows and rotary cultivators that ensures an extended operating life, maximum smooth running and a high resale value. Gear wheels and bearings run in a single oil bath and so are maintenance-free – no grease nipples.

(1) Robust gearbox

(2) Highly-hardened spur gears with large teeth contact area

(3) Exact spacing of all bearing seats for a maximum smooth running

(4) Heavy-duty taper roller bearings with wide spacing between mounting points

(5) Large clearance between tool carrier and smooth trough base for blockage-free mulch sowing and optimum though passage

(6) Double sealing system with cassette sealing ring against oil loss and labyrinth seal against ingress of plant fibres and dirt

(7) The tine carrier and the shaft are forged from one piece and have a large shaft diameter, KG rotary cultivator ∅ = 60 mm

(8) Quick + Safe System with proven, tool-less tine change solution and integrated stone safety protection

Quick-System – Quick change tine system

Quick_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 as there are no tine fixing bolts that require retightening. Even converting tine operation from “on-grip” to trailing mode is quick and simple. The tines, which are forged from special hardened steel, are elastic and wear-resistant.

Safe-System – Integrated stone protection

Safe_System

The sprung tine fixing system allows the tines to yield when stones are encountered. The tines are firmly clamped in the socket in the centre of the tine carrier. The socket becomes wider towards the outside so that the horizontal part of the tine can twist out of position while remaining sprung. Much of the shock is absorbed when the tip of the tine hits a stone. This method of tine fixing on the KG provides safety on stony soils and means that the tines can be used “on-grip”.

PW tooth packer roller/500 mm/600 mm

Zahnpackerwalze(1)

The PW tooth packer roller features a good self-driving effect and, with its leading teeth, it performs a good reconsolidation all across the whole surface.

Due to its performance, the tooth packer roller is universally usable.

• Consolidation is completely over the entire soil surface
• Runs blockage-free on sticky soils and where there is a lot of straw
• Scrapers, fitted as standard, are wear-resistant thanks to a hard metal coating (3 to 5 times longer service life in comparison to non-coated scrapers)
• Low set scrapers ensure a smooth surface even in wet soil conditions

KW wedge ring roller 580 mm

Keilringwalze(1)

The KW wedge ring roller benefits from a wide range of applications. Due to its design, the strip-wise reconsolidation is ensured in virtually all soils and under any conditions.

There is no chance of sticking, clogging or blocking up.

• Universal for all soils and conditions
• Reconsolidation in strips
• Even in heavy soils, sufficient loose earth is available for the optimum seed coverage
• Very well suited to any weather, no matter whether moist or dry
• Smooth coulter travel due to the pre-formed seed furrow

Wedge ring roller: targeted reconsolidation – for optimum plant development

Keilringwalze_Pflanzenaufgang

A roller’s primary task is soil reconsolidation. The wedge ring roller uses rubber rings to form reconsolidated strips in which the seed is sown. The harrow that follows covers the seed with loose soil from the unconsolidated area.

Reconsolidating in strips ensures that the soil structure around the plants is always right for the current weather conditions, and so provides the best chance of rapid, uniform plant development. The wedge ring roller thus serves as insurance for just-in-time tilling.

The wedge rings leave a homogeneous, pre-consolidated strip without any stud marks. Compared to rollers with other profiles, this is a decisive advantage, resulting, above all, in a smooth run of the sowing coulters.

Enclosed roller

Geschlossene_Walz

In general: on loose and light soils solid rollers carry better than open rollers. In addition, solid rollers tend to block less. Exactly for this reason on the wedge ring and Matrix wedge ring rollers, the rubber rings are fitted to an enclosed tube. When the rings sink into the loose soil, the tube carries the weight across the entire length.

There is no chance of sticking, clogging or blocking up.

Seed embedment with the RoTeC Control disc coulter for conventional and mulch sowing

RoTeC_Control

RoTeC Control coulters are maintenance-free and work extremely well yet with little wear and tear. Even where large amounts of straw and trash prevail they won’t block up. The combination of the sowing disc on the one side and the furrow former on the other create the perfect seed furrow and optimum seed control. The elastic polyurethane disc also helps to create the seed furrow, accurately controls the pre-set sowing depth and prevents soil from sticking to the sowing discs.

(1) For exceptionally deep sowing, the depth guidance disc can be easily removed.

(2) RoTeC Control coulter with Control 10 depth guidance disc with 10 mm wide contact surface.

RoTeC: now proven by over 1,500,000 units! Awarded an Agritechnica silver medal

D9-3000-Super

The very even and exactly controlled depth guidance of the RoTeC Control coulter is achieved via the Control 10 depth guidance disc, with a contact surface of 10 mm, or the Control 25 depth guidance option with a contact surface of 25 mm. As this depth guidance is fitted on the side of the coulter, this principle operates with more accuracy than coulter systems with a following, rigidly attached separate depth guidance roller. The depth guidance discs or rollers provide the basic setting of the sowing depth easily and comfortably via the coulter pressure. If necessary a notched quadrant allows for the readjustment of the sowing coulter in 3 steps.

Quality and reliability throughout:

Avant_Fendt

• Coulter discs made from high grade Boron steel
• Shallow angle of inclination for reduced soil movement
• Wear resistant polyurethane disc acts as an adjustable depth guidance roller and for cleaning

The large clearance between the front and rear rows of coulters ensures a blockage-free sowing operation, even where large amounts of straw prevail.

With only one cutting disc per coulter, AMAZONE ensures – even at a 12.5 cm row spacing and mulch sowing at high speeds – a blockage-free material passage in between the coulters.

Hydraulic coulter lift and coulter pressure adjustment

For solo soil cultivation the coulters, together with the following harrow, can be raised hydraulically. This enables the quick and flexible adaptation to particular situations such as in areas of poor straw incorporation, in part areas where a preliminary pre-work is necessary. The targeted pre-loosening of the headland or other compacted areas is also possible.

The coulter pressure of the Avant is, as standard, adjusted hydraulically.

Seed embedment with either RoTeC and the RoTeC+ coulters for conventional and mulch sowing

Saat_einbetten

For sowing in especially large fields and for more arduous operating conditions AMAZONE has developed the RoTeC+ coulter. The coulter features a disc diameter of 400 mm and is made from 4 mm thick hardened Boron steel. In this way, the wear is kept to a minimum and an already long service life is further extended.

For trouble-free sowing at high forward speeds and in heavy soils where there is much straw, the coulter pressure has been increased to a maximum of 55 kg.

Optional seed press rollers for the RoTeC and RoTeC+ coulters

D9-AD3

The following press roller runs precisely in the seed furrow and, under dry conditions, presses the seed (such as rape and other fine seeds) to the bottom of the furrow. Depth guidance of the coulter is still carried out via the depth limiting disc. The rollers feature an adjustable depth setting, can be removed without tools and can be operated in combination with the Exact harrow (not in conjunction with shallow sowing discs).

Seed coverage with the Exact harrow or with the Exact harrow S

Exaktstriegel

The Exact harrow covers and levels the open seed furrow without blockage even with large amounts of straw present. With its individually pivoting harrow elements, the Exact harrow follows the undulations of the soil perfectly, ensuring an even seed coverage on soils either with or without straw.

The harrow pressure is centrally adjusted mechanically via two spindles. On the hydraulic harrow pressure adjustment, a pair of locating pins predetermines the minimum and maximum settings. This way both the harrow and the coulter pressure are linked together and so can, during operation, be adapted to changing soil conditions by the use of just one tractor control valve.

In conjunction with the RoTeC+ coulter, the 15 mm strong Exact S following harrow can be used. It gives little wear and provides good seed coverage even in most difficult of operational conditions.

Pre-emergence markers

When creating tramlines, the marker discs automatically lower and mark where the tramline will be created. This means that the tramlines are visible prior to the seed emergence.

Optimum weight distribution

Optimale Gewichtsverteilung

Front hopper and rear combination are mounted to the tractor in just a few minutes and without tools. The seed tubes are fitted down the side of the tractor via retainers that can remain there even when the Avant has been dismounted. By means of over-centre catches, the seed tubes to the font hopper and the rear combination are quickly connected. The front hopper is coupled onto the tractor’s front linkage and the hydraulic couplings are plugged into the tractor. The same procedure is carried out for the rear: The rotary cultivator is mounted onto the lower link arms, the top link arm connected and the hydraulic hoses are plugged in. That just leaves the data cable to be fitted to the AmaTron 3 and then the sowing operation can start.

Compact on the road

Schnell auf der Straße

For transport on public roads the rear mounted combination can be hydraulically folded to a transport width of less than 3 m and a transport height of less than 3.7 m.
