MasterDrill A 250 Vogel & Noot MasterDrill A 250 Specifications & Technical Data (2007—2017)

New tank cover

Can be folded up in one piece, allowing you to carry out filling more easily. The improved sealing prevents the penetration of water and dust.

Fan

The fan produces the airflow needed for the seed distribution. High air volumes with low air speeds guarantee gentle transportation of the seeds. The fan is powered mechanically directly via the PTO shaft of the tractor (D and HD types) or via the PTO shaft through the drive of the cultivation implement (A types). On request, it can also be powered hydraulically with an oil motor, which is optionally capable of load sensing.

Lighting

All MasterDrills are approved for road transport due to the fact that their transport width is less than 3.00 m, have a lighting system with warning boards, lights and rear reflectors as standard.

Electronic tramline control TRAM GRX

The electronic system switches all common tramlines by stopping the seed metering wheels of the corresponding sowing drives (magnetic coupling).

Cam seed metering wheel system

The tried-and-tested cam seed metering wheel system guarantees precise sowing in all conditions and with all types of seed. In the case of normal sowing with cereals, peas, soy etc., amounts of up to approx. 400 kg/ha are possible. In the case of greatly reduced sowing, e.g., rape or alfalfa, the fine sowing lugs are attached to the seed metering wheel.

Tried-and-tested technology

The system of the central bucket wheel metering has been in use for many years and as a result, has proved itself over and over again. The MasterDrill metering system stands for precise metering and, in combination with seed depositing, is the basis for cost-effective sowing because deviations from the required sowing rate mean a direct increase in costs or reduced yield.

Rape brush

The rape brush, which is included as standard, must be attached for the sowing of fine seeds such as rape. This brush gives additional cleaning to the metering chambers, which are on very small settings for this purpose, meaning that there is very precise metering even in the case of small sowing rates.

Fine metering

The metering unit can be reset to fine sowing very simply and without the need for tools when there are especially small sowing rates, e.g., rape or grass.

Electronic tramline control/monitoring

The current version of the electronic control and monitoring unit, the Drillmat III, switches the tramlines via electromotive valves in all common rhythms. As part of this process, the seeds are returned to the tank via a buffer chamber (seed return). This means effective seed saving. In addition to the switching of the tramlines, the monitoring system provides comprehensive information about the device functions such as working speed, hectare performance, fan speed, metering function, and tank contents (with height-adjustable sensor).

Hydraul. pre-emergence marker

This marks the switched tramlines for maintenance or fertiliser procedures before the emergence of the seeds. The discs leave an easily visible marking on the ground. The pre-emergence marker can optionally either be controlled directly via a hydraulic control unit or automatically through connection to the monitoring system.

Tine and gangway/steps

The exact tine guarantees exact seed coverage and its angle is adjustable. The gangway combined with the tine reaches over the entire width of the device and is therefore particularly secure and convenient.

Farm Operations

Mr Wallner operates an 85 ha dairy farm. He mainly grows cereals and fodder crops, and cultivates his soils using a plough and mulch. This dedicated farmer has been using a Vogel & Noot ArterraGrip 300 rotary harrow in combination with a pneumatic seed drill since 2007. "Our soil is very stony. We therefore needed a really robust and stable soil cultivation machine. The ArterraGrip rotary harrow is exactly that and was therefore the best choice for us. It is also very compact and very easy to maintain." Mr and Mrs Vandler run an arable (particularly maize cultivation) and dairy farm. The farm's soil is loamy and limy. Mr Vandler: "In 2009 we decided to buy a rotary harrow. In the end we opted for the Vogel & Noot ArterraGrip 400. The most impressive feature of the Vogel & Noot rotary harrow is the excellent mixing of crop remains. The ArterraGrip also works extremely well on uncultivated soils and the work is very neat. This machine has proven to be the best choice for us when it comes to preparing the seedbed for sowing." Mr Cernel owns 40 ha of arable land and has been cultivating the soil with a Vogel & Noot Arterra MS 300 since August 2009. He uses the rotary harrow in combination with the Vogel & Noot MasterDrill A 300 seed drill. Mr Cernel also owns a Vogel & Noot Grubber TerraFlex with a mechanical seed drill. "The biggest advantage for me is that by combining the rotary harrow and seed drill, I only have to cover the field once in order to cultivate the soil and sow the seeds. The design of the Vogel & Noot machines is also impressively robust and high quality, which makes it easy to work with heavy soils."

Sowing technology success factor

Even a homogenous seedbed is an important basic requirement for the uniform germination and early development of the whole crop. Of course, natural factors such as light, water and the type of soil also play an important role. However, these factors are not influenced by sowing technology. It is therefore all the more important to use a perfect cultivation process to give the young plants the optimum possibilities for growth, irrespective of whether conventional or conservational sowing procedures are used. The following criteria are crucial for a uniform emergence and healthy development of the young plants: Constant seed depositing depth Even covering with fine soil Good soil consolidation, no plant remains in the sowing drills Even pressure No deep tramlines or compressed zones in the soil Even distribution of plant remains (influences light conditions and nutrient reservoir).

VN seed drill application areas

Vogel&Noot seed drills are made to do a professional job and cover a broad range from conventional sowing after ploughing to powerful mulch sowing. A wide selection of different device designs with various sowing options offers the best possible solutions and creates the basis for a successful crop.

Conventional soil cultivation

Conventional soil cultivation is characterised by the annual use of the plough. Under good conditions, ploughing works all plant remains deep into the ground. Any existing weeds are destroyed because working the plants deep into the ground means that they are deprived of both air (for respiration) and light (for photosynthesis). The cultivation depth is usually in a range of 15 – 30 cm. After ploughing, the ground is very loose (high volume increase) and displays large hollows within the ploughing depressions. Both corresponding reconsolidation and sufficiently fine clod-breaking are required to ensure that optimum germination conditions are produced for the crop that is cultivated next. These tasks can both be achieved via secondary soil cultivation. As the plough leaves behind a clean table, conventional seed drills with shoe coulters can be used without them getting clogged with plant remains.

Mulch sowing/conservational cultivation technology

In the case of mulch sowing, the ground is not rotated before sowing (= without plough), and the plant remains are mixed with soil measuring 2 – 15 cm on the ground surface. Cultivation can be carried out in a separate process or at the same time as sowing. The ground covering (area proportion of the plant remains/straw remains in the whole area) varies between 20 – 80% depending on the cultivation implement and working depth. Significant cultivation targets in the case of mulch sowing include: Create a sufficiently high fine earth proportion Even soil loosening (working depth according to requirements) Incorporation and shredding of the plant remains Removal of existing old weed growth. Today, there are a variety of different types of devices for these tasks, such as cultivators, disc harrows, and rotary cultivators. The quality of the work has a significant effect on the success of mulch sowing.

Mechanical attachment seed drills for soil cultivation machines

The SuperDrill AL and A mechanical seed drills never fail to impress thanks to their simple and robust construction. The fact that they are mounted on the packer roller of the rotary harrow means that the large seed hopper volumes permit rapid cultivation in three working widths (2.5 /3 / 4 m).

Mechanical seed drill for 3-point mounting

The SuperDrill D mechanical seed drill is used as an attachment with the 3-point coupling. It is robust, easy to use, and permits precise seed depositing in combination with exact seed metering. The large seed hopper facilitates high outputs in combination with 3/4 m working width.

Pneumatic seed drills for 3-point mounting

With its 3-point mounting, the MasterDrill D is suitable for use direct on the tractor, but also in combination with various drawn cultivation implements. The MasterDrill D seed drills are ideal for powerful sowing in deposited work procedures with low power consumption (6.00 m from approx. 100 PS).

Other features

High-volume tyres reduce the soil pressure and avoid tramlines. A favourable centre of gravity reduces the lifting force requirement. Therefore, sowing can be carried out with large working widths, even when smaller tractors are used.

Large tail wheel

The large diameter of the tail wheel guarantees very even driving of the sowing shaft and therefore exactly conforms with the sowing rate.

Hydraulic coulter lifting

The depth control bar is used as standard for hydraulic coulter lifting. In the case of rotary harrow-seeder combinations, this increases the ground clearance during lifting. Tail wheel and tine with steps are lifted at the same time.

Depth control bars

In the case of all SuperDrill seed drills, the stable steel sowing pipes are positioned on the depth control bar and are therefore guided exactly into the depression. The precise deposit depth is especially important for quick and even growth of the seed.

Running wheels

The generous dimensions of the running wheels (200/60-14.5) reduce the soil pressure and guarantee incredibly even driving of the sowing shaft.

Sickle coulters

The SuperDrill sickle coulters are not sensitive to harvest remains thanks to their special shape (circular arc). As these are not contracted, blockages are avoided. The wearing part is also reversible and can be used on both sides, meaning that the service life of the SuperDrill coulters is twice as long as it is for conventional shoe coulters.

Double disc coulter

The double disc coulters with 300 mm diameter are equipped with a robust bearing. Double-sided scrapers and a covering on the upper side help to prevent the formation of blockages, ensuring that double disc coulters work optimally, even under conditions where there is a large amount of harvest remains. The double-sided ball bearing has a very compact housing. The large pass that is therefore possible between the new double disc coulters provides blockage-free working conditions, even in complicated mulch sowing conditions. The discs, made from rust-free V2A steel, are particularly robust in sticky soils.

Sowing shaft drive

The sowing shaft is driven via the drive cassettes and the standard gear mechanism. The gear mechanism offers a number of setting opportunities for the required sowing shaft speed. The optional gears are a particularly convenient solution, and the special construction of these gears guarantees very even driving of the seed metering wheels, resulting in incredibly exact sowing. The continuous gears can also be equipped with an electrical remote seed quantity adjustment if required.

Shoe coulter

Conventional sowing with the tried-and-tested shoe coulters. The standard shutter flap prevents blockages in the case of backwards movement. The large swing area means that the drill coulters avoid obstacles, preventing damage.

Compaction roller (optional)

The compaction rollers (250 mm diameter, 42 mm wide) are equipped with a finely adjustable height alteration system (perforated screen). They guide each individual drill coulter to the precise depth, ensuring incredibly accurate seed depositing. Pressure rolling increases the soil consolidation and therefore helps quick emergence.

Coulter pressure adjustment

All MasterDrill seed drills are equipped with continuous central coulter pressure adjustment (spindle), which can also be hydraulically operated on request. Additionally, individual coulters can have their pressure adjusted.

Track indicator + depth control

The hydraulically operated disc track indicators (double-acting control unit) are equipped with a depth limiter. The track indicators can optionally be set to the tractor wheel track or also to the centre of the tractor, with an overload protection system via shear-off bolt.

Sowing tine

The sowing tine provides optimum seed coverage, even when there are harvest remains. The angle of inclination of the tines has 3-fold adjustment, and the tine height can be continuously adjusted, which is important in the case of light soils. In heavy soils, the tine pressure can also be increased via a spring in addition to the unladen weight. The tines can also be supplied in a strong 10 mm model for use in heavy soils.

Individual coverer for the shoe coulters

These are directly assembled onto the shoe coulter, adjusting exactly to the soil, which means that they cover the seeds particularly evenly. They can be used in light soil conditions with no harvest remains.

Track loosener (only for D and HD types)

Track looseners are available for loosening the tractor tracks in front of the seed drill and for the wheel of the drill, with continuous height and side adjustment.

Rapid discharge from seed hopper

Any remains in the hopper can easily be removed via the residue emptying supports in the hopper and the emptying flap on the metering unit.

Steps and platform

All VN seed drills can be equipped with convenient access routes to ensure that the seed hopper can be reached safely. Non-slip step tread and additional railings ensure safety is maintained.
