Perfect seeding combination with a rotary harrow
Advantages of Pronto KR
- Universal range of use after plough and for mulch sowing even on heaviest soils
- Rotary harrow for perfect fine-soil production even in heavy soils
- 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
- Cracker packer steel roller for optimum levelling and consolidation of the seedbed
- 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
- 6 m working width
- Power demand starting at 160 kW / 220 HP

Very stable rotary harrow with tines in dragging position. 20 rotary segments for 6 m working width.
Switch-off couplings at each half of the rotary harrow are responsible for the overload protection.
Stable gear tank design
Via a change gear drive the rotary speed can be adjusted to the soil and operational conditions.
Rotary speeds for 1.000 rpm pto-shaft speed:
Standard 21/24 cogs: 234 or 306 rpm
Optional 19/26 cogs: 196 or 367 rpm
Optional 17/28 cogs: 162 or 441 rpm
Tine quick-change system
The tines are fixed in pairs with a retaining clip at the rotary support and secured with a cotter pin.
The tines can be changed without tools.
Floating rotary harrow segments
Each one of the two 3 m halves floats around a central bolt and can adapt to the contours.
Thus, working depth and power can be saved compared to a 6 m rotary harrow.
Guarantees additional levelling and steadying of the soil in front of the packer.
Can be adjusted to the working depth of the rotary harrow in a perforated strip.
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.
Cracker packer Ø 54 cm
Ring spacing 12,5 cm. Steel packer roller, ideal for being used in a rotary harrow. Excellent consolidation and crumbling effect on intensively cultivated soils.
Very flexible use on heavy and very heavy soils due to adjustable intermediate knives. Resistant to cloggings under wet conditions.
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
The seed depth is adjusted with a 24-wrench via a cog wheel that runs in the cog strip. A bolt fixes the seed depth.
Seed bar mounted at the packer frame
Seed bar and packer frame form a unit and are mounted with a parallelogram at the rotary harrow.
If the working depth of the rotary harrow is changed, seed depth and coulter pressure are not affected.
Coulter pressure adjustment
Via the spindle the shaft where the TurboDisc coulters are mounted with a rubber bearing is twisted.
By twisting the shaft the pre-tension of the rubber elements changes and thus also the coulter pressure to 120 kg per coulter.
The Pronto 6 KR has 2 distribution towers as a standard equipment:
Standard: resp. 20 exits/coulter (15 cm row spacing)
Optional: resp. 24 exits/coulter (12.5 cm row spacing)
48 TurboDisc seed coulters - optional
Row spacing 12.5 cm. The row spacing, thus, is identical to the ring spacings of Cracker or FarmFlex packer.
The TurboDisc seed coulters always sow into evenly consolidated soil. Moreover, the fine earth rate behind the packer rings in general is higher than between the rings.
Recommended in general - except if there are high amounts of organic material. 40 TurboDisc seed coulters - standard
Row spacing 15,0 cm. For mulch seed with a high rate of straw in the seed horizon the larger row spacing is favourable.
The clogging tendency of the seed bar decreases considerably - particularly at the relatively low operational speeds of the rotary harrow combination.
