Pronto DC
Universal seeding technology for all conditions

Advantages of Pronto DC
- For precise sowing after plough, mulch sowing or direct seed
- The Pronto DC achieves high speeds while maintaining the exact seed placement due to its unique packer. This is due to a very good levelling effect with high clearance. Thus, the forming of waves is effectively prevented.
- Our packer concept is a prerequisite for a good crop emergence in wet and dry conditions
- Turbo Disc seed coulter with uniformer for a considerable clogging reduction and exact seed placement
- Easy handling due to central adjustment of the seedbed-preparation unit and the packer-seed unit
- Uniform planting depth over the entire field due to predefined depth difference between packer system and coulter
- PPF system for exact fertilizer-depot placement below the seed rows
- 3 - 9 m working width
- Power demand starting at 80 kW / 110 HP
Distinguishing Features of Pronto DC
- Trailed seed drill combining seedbed preparation, consolidation, sowing and pressing
- 2-row DiscSystem for the production of fine earth at high working speeds
- The scraper between the packer tyres has decisive advantages in wet conditions as its large clearance allows for a uniform consolidation over the entire working width

Equipment
Linkage
Discharge of the remaining quantity
Standard equipment for all Pronto models. Allows for an almost complete discharge of the hoppers.
Only a very low seed and/or fertilizer quantity has to be discharged via the metering unit.
Double hopper version Grain & Fertilizer
Pressurized hoppers partitioned in a ratio of 40% at the front and 60% at the rear.
Both metering units meter into one common distribution tower.
Thus, seed and fertilizer are placed together in one furrow.
Attention: This system canNOT be compared to the PPF system. It should only be used under corresponding climatic conditions (e.g. very high annual rainfall) and after having consulted a plant-production counsellor.
Fan
Hydr. fan pto-drive
If the output of the hydraulic pump of the tractor is too low or if there is a danger of oil getting mixed if more tractors are used, pto-drive has to be preferred.
For pto-drive always 11 cm³ gear pump.
Hydr. fan drive axial piston pumps
Direct drive with 5 cm³ oil motor for Pronto 6 DC and Pronto 6 AS single hopper.
Direct drive with 10 cm³ oil motor for Pronto 3 to 6 DC/AS with double hopper, Pronto 7 to 9 DC and Pronto 8 to 12 SW with single hopper.
Direct drive with 19 cm³ oil motor for Pronto 8 to 12 SW with PPF.
DiscSystem
2-row DiscSystem
The discs are always mounted in pairs on one shaft, thus allowing for a large clearance.
Ideal for mulch seed as resistant to cloggings.
Mounted in absolutely maintenance-free and very wide rubber elements. Prevents the setting angle of the discs from changing in hard soil conditions.
Working depth adjustment DiscSystem
The working depth of the DiscSystem is adjusted hydraulically and and can be adjusted while driving.
The driver can see the position of the DiscSystems on a scale at the machine.
Discs Ø 46 cm
Serrated discs easier penetrate the soil.
Due to the small diametre the discs turn very fast, thus facilitating the production of fine earth.
The considerable curve of the disc improves the mixing effect and the power requirement is lower than for a straight disc.
Spade discs
Run in each disc row on the outside.
They prevent that too much soil is transported to the edge plates.
They prevent the forming of ridges and allow for an optimum continuation.
Depth adjustment DiscSystem
The working depth can be adjusted steplessly hydr. while driving.
The driver can see the position of the DiscSystem on a scale at the machine.
Working depth adjustment DiscSystem
The DiscSystem is lifted on the headlands via hydr. cylindres. By means of memory cylindres the discs return to the set position when being lowered. The working depth can be adjusted steplessly while driving. The driver can see the position of the DiscSystem on a scale at the machine.
Packer
PU (Poly-Urethan) tyre filling
For chassis and intermediate axle packer.
Recommended on sites where the tyres could be damaged by stones, thorns etc.
Does not affect the millability and thus the self-cleaning effect of the tyre. Increases the weight per tyre by approx. 42 kg for tyre size 7.50-16 AS and by 22 kg for 185/65-15 AS.
Front packer 7.50-16 AS / Ø 78 cm
For an even consolidation over the whole working width. Due to the levelling effect it is possible to reduce the working depth of the disc harrow and, thus, to save power.
Coulter bar
TurboDisc seed coulter
Controlled by press wheels with a soil adjustment of +/- 7,5 cm. Adapts optimally to the soil contours.
Designed for exact seed placement at high speeds. Allows for a secure and even emergence due to a perfect embedding of the seed and an immediate seed-soil contact.
Maintenance-free rubber bearing
Overload protection and shock absorber which guarantees smooth running of the seed coulters even at very high speeds.
Uniformer and scraper
Uniformer: fixes the seed in the seed furrow and prevents it from being blown out by high air quantities.
Scraper: carbide-covered and self-adjusting. Keeps the space between the discs clean and prevents cloggings.
Press-wheel controlled seed harrow
Mounted at the „short“ TurboDisc seed coulters. The depth of each harrow element is individually controlled by the press wheel even in uneven soils. The harrow guarantees that the seed is covered even on heavy soils.
Press wheels 5 cm
Standard. Recommended on medium and heavy soils.
Equipped as standard with carbide-covered scrapers. Soil does not build up - the outer diametre of the wheels thus always stays the same, and the seed depth cannot change.
Mechanical coulter pressure adjustment
The pre-tension of the rubber elements is steplessly adjustable up to max. 120 kg per coulter via a crank.
Seed depth adjustment
For the Prontos 3 to 6 DC the seed depth is adjusted centrally at the lifting cylinders of the chassis and the side wings via spacer clips.
Seed distribution tower
Pronto 3 to 6 DC are equipped with a seed distribution tower which is mounted at the rear of the machine and is easily accessible.
The seed tubes can be laid relatively short and steeply dropping towards the TurboDisc seed coulters, thus reducing the clogging tendency.
Mechanical half-width shut-off
Optional from Pronto 4 DC on. Not possible for PPF system. Is integrated into the cover of the distribution tower. The cover plate has to be turned manually to block the respective half of the machine.
The seed size has to be reduced manually by 50% at the terminal.
Maize distributor double row
Not available for Pronto 6 DC with electric half-width shut-off.
The maize distributor allows for sowing maize with a larger row spacing of 15 cm.
The maize distributor is placed on the distribution tower and only equipped with the number of exits which are necessary for sowing maize.
The seed tubes leading to the respective TurboDisc seed coulters are simply connected with the exits of the maize distributor.
Via a perforation in the maize distributor spare air can escape via the exits of the main distributors which are not used - for a good lateral distribution.
Maize distributor double row
The illustration shows the row distribution for 60 cm double rows for a Pronto 3 DC:
Black lines: seed row spacing 15 cm.
Red marks: seed rows that are used for sowing maize - all other rows remain free from seed.
Double rows with a spacing of 60 cm (from one double row centre to the next one).
Blue marks: show the arrangement of PPF fertilizer coulters (if fitted).
One PPF fertilizer coulter respectively supplies one seed coulter.
Two distribution towers
The machines dispose of two distribution towers which are placed directly above the seed bar and are easily accessible.
The seed tubes can be laid relatively short and steeply dropping towards the TurboDisc seed coulters, thus reducing the clogging tendency.
Mechanical half-width shut-off
There is a valve in the fall sluice below the metering unit which is used to block the seed supply to one distribution tower.
The seed size has to be reduced manually by 50% at the terminal.
Electric half-width shut-off
Via a servomotor the valve below the metering unit can be closed resp. opened electrically.
It is operated via the terminal of the DrillManager.
The DrillManager automatically reduces the seed quantity by 50%.
Seed depth adjustment
Is made directly via spacer clips at the lifting cylinders of the seed bar.
The more clips are inserted, the DEEPER is the seed depth. The seed depth adjustment of the Pronto 3 to 6 DC works the other way round.
Options
Press wheels 7,5 cm
Only recommended on very light soils. Equipped as standard with carbide-covered scrapers. Soil does not build up - the outer diametre of the wheels thus always stays the same, and the seed depth cannot change.
Pre-emergence marker
Are mounted directly at the TurboDisc seed coulter. The depth is controlled via a press wheel.
The desired track width has to be indicated when ordering.
The aggressivity of the pre-emergence marker is adjusted via a depth stop.
Hydr. coulter pressure adjustment
Recommended on very changing soils.
The basic adjustment is made by means of the crank. Via the hydraulic cylinders the coulter pressure can be increased while driving, e.g. on heavy subareas.
At the same time the coupling to the seed quantity regulation allows for an automatic changing of the placed seed quantity.
Track eradicator discs
Two disc pairs which are mounted in such a way that they run in each disc row behind the tractor tracks.
Can be adjusted more deeply to loosen the tractor tines. Absolutely resistant to cloggings compared to track eradicator tines.
Front packer
Due to the levelling effect in combination with consolidation it is possible to reduce the working depth of the disc harrow and thus to save power and diesel.
Intermediate axle packer
If the tractor is equipped with wide-base tyres or twin tyres, consolidation over the whole working width can be achieved even by only using the intermediate axle packer.
Fertilizer disc coulters
Fertilizer coulters in a one-disc design. With integrated drag coulter which among others acts as a scraper. The open design allows for a high clearance and a low clogging tendency.
Maintenance-free oil-bath bearings. The disc supports are mounted in rubber elements.
Container micro-granulate
The micro-granulate hopper is integrated completely into the seed hopper of the Pronto.
The filling is made via the feed opening of the seed hopper.
Functioning micro-granular unit
Its pneum. system is integrated into the pneum. system of the Pronto. The micro-granulate is led into the seed current after the main metering unit and is - together with the seed - distributed to the seed coulters via the distribution tower.
It is operated via the terminal of the DrillManagers.
Front- and side packer Ø 65 cm
Optional for Pronto 3 and 4 DC (rigid). 185/65-15 AS
For an even consolidation over the whole working width. Due to the levelling effect it is possible to reduce the working depth of the disc harrow and, thus, to save power.
Intermediate axle and side packer Ø 78 cm
Optional for Pronto 6 DC. 7.50-16 AS. For an even consolidation over the whole working width.
Due to the levelling effect it is possible to reduce the working depth of the disc harrow and, thus, to save power.
Front packer SteelDisc Ø 58 cm
Optional for Pronto 4 DC rigid. Heavy steel ring packer with excellent consolidation and cutting effect on heavy soils. Ideal for stony sites.
1-row hydr. Crossbar
Optional: available for Pronto 3 DC, 4 DC and 6 DC - not with PPF fertilizer coulters.
Is placed between the DiscSystem and the tyre packer. The aggressivity can be adjusted steplessly hydr. (see scale). Not possible with PPF fertilizer coulters.
Makes sense when sowing on ploughed soils. Relatively high horsepower requirement.
Not recommended for mulch seed because of the danger of clogging.
Harrow behind 1-row DiscSystem
Optional: available for Pronto 3 DC, 4 DC and 6 DC - not with PPF fertilizer coulters.
Is placed tbetween the DiscSystem and the tyre packer. Is adjusted mechanically via a hole pattern.
The harrow breaks the earth current created by the DiscSystem, thus encouraging the crumbling and levelling in front of the packer. Recommended on light soils.
Electric half-width shut-off
Optional: available only for Pronto 6 DC. Cannot be combined with double hopper version PPF, Grain & Fertilizer system or micro-granular unit.
In case of an electric half-width shut-off the Pronto 6 DC is equipped with two distribution towers.
By moving a valve the servomotor blocks one distribution tower. The DrillManager automatically reduces the seed quantity by 50%.
It is operated via the terminal of the DrillManager.
Double hopper version with PPF system
Hopper partitioned with a ratio of 40% at the front and 60% at the rear.
Pressurized hoppers - designed for spreading high fertilizer quantities. Air-tight filling and discharge openings.
PPF system
The fertilizer coulters are arranged centrally in front of a tyre. The fertilizer thus is placed centrally between two seed rows.
In order to be able to place the fertilizer below the seed, the fertilizer coulters can be charged with a coulter pressure of up to 200 kg.
Micro-granular unit
Optional: available for Pronto 3 DC, 4 DC, 4 DC rigid and Pronto 6 DC.
Not possible with PPF system or electric half-width shut-off.
Allows for the placement of micro-granulate directly into the seed furrow (e.g. insecticides). The granulate is placed in the seed furrow together with the seed.
Application quantity approx. 10 kg/ha.
Drawbar extension: Pronto 6 DC
Optional for Pronto 6 DC with lower link linkage. Extension by 800 mm. Allows for tight turning with twin or terra tyres
Drawbar linkage
Optional for Pronto 6 DC. Also available with Scharmüller coupling Ø 80 mm.
The Pronto 6 DC is lifted at the rear via the tyre packer and at the front via the hydr. drawbar.
Hopper extension: Pronto 4 and 4 DC rigid
Optional for Pronto 4 DC and Pronto 4 DC rigid. Only possible for single hopper. Increases the seed hopper capacity by 700 l.
Track eradicator tines with attachment frame
Are swivelled out hydraulically when lifted. Loosen the soil in the area of the tractor tracks.
Only suitable for mulch seed to a limited extent (prone to cloggings if there are large quantities of harvest residues).
Hydr. filling auger
Output 400 kg/min. With double hopper it is only possible to fill the rear chamber.
Hydraulically driven, requires an additional double-acting control device.
In transport position foldable and lockable.
