Compact Disc Harrows
Heliodor
Maintenance-free high-quality axial angular ball bearings guarantee perfect permanent function of the discs. The bearings pick up not only the radial, but also the axial forces of the hollow discs and they are also en- closed by a sealing ring. There is no chance for dust and dirt due to an additional labyrinth sealing ring.
The solid headstock is known for high durability and the ease of serv- icing. The multiple adjustment possi- bilities make the quick adaptation to different tractors easier. The lower links will be fitted to a one-piece, spring-loaded drawbar. So imple- ment vibrations will be cushioned by the drawbar and not be transferred to the tractor. Additional weights can be fitted to the headstock to ensure a good penetration also in heavy soil conditions. Rigid implements can pick up up to 400 and folding imple- ments up to 500 kilograms.
The Heliodor comprises two rows of single suspended notched hollow discs, which are extremely wear resistant with a diameter of 465 mm and 5 mm thickness. The inclination of the discs leads to a good penetration behaviour. The discs of the LEMKEN Heliodor are arranged with distances of 250 mm in staggered positioned rows. The result is a line distance of 125 mm which enables intensive soil cultivation.
Rubin
of the working elements
The LEMKEN Rubin has 250 mm disc spacing on both front and rear rows. This provides blockage-free working. Front and rear disc rows are staggered to give working alignment of just 125 mm spacing between each working row. A disc cultivator using discs smaller than the LEMKEN Rubin’s would have to have to work substantially deeper to achieve complete cultivation across the working width. And if the disc cutting angle is less than that of the Rubin, then com- plete working width cultivation can often be impossible.
This means the implement would need to be worked deeper to achieve the same quality of work similar to the Rubin. Also deeper working depth would mean the advantage of light draught requirement is lost and higher power requirement is needed.
The LEMKEN Rubin notched hollow discs have a diameter of 620 mm and a thickness of 6 mm. This guarantees a superb working quality.
Through penetration performance and large cutting angle, the Rubin discs achieve a high standard of consistent cultivation action over the entire working width at working depths as low as only 7 cm. The large discs have four times the contact area than smaller discs. Therefore down time is reduced, working time in the field is maximised and maintenance costs are reduced.
contour precisely
Rubin concave discs are separately attached on indivi- dually pre-tensioned sprung legs. This in comparison with other methods of attachment clearly shows that the spring element on each leg delivers a continuous optimum pressure to keep the discs at the correct depth in the soil and enable maximum working intensity.
The attachment system also always keeps individual discs on-track with no sideways movement. Especially on hard ground and heavy soils this system proves much superior compared with those using the rubber attachment systems. Again this guarantees consistently cultivated bouts with no gaps left.
Cultivators
Kristall
With TriMix shares, the Kristall has the perfect equipment for the initial shallow stubble cultivation.
- The share points with their long parallel edges are optimized to combine good soil penetration with minimum draft.
- The overlapping arrangement of the wings guarantees that the straw is worked in intensively over the entire area, even at low working depths.
- All soil capillaries are broken, preventing the soil from drying out.
The tines and concave discs, for levelling, are arranged in such a way that the flow of soil comes to rest before the next tool. As a result, the Kristall always operates uniformly across its working width, without blockages, even under tough conditions.
- The concave discs behind the tines ensure additional good lateral distribution of straw and soil and reliably level the surface.
- The roller reconsolidates the soil uniformly across the working width.
If the working depth of the Kristall compact cultivator is changed, the concave discs adapt to the new working depth without further adjustment.
- A parallel linkage holds the concave discs and the rear rollers in the correct position at all times and ensures they are constantly at the correct working depth.
- On the folding version, of the Kristall, a suspension system for each roller section ensures effective contour following, and even reconsolidating of the soil across the width.
Smaragd
The Tandem double roller, which consists of a scrolled tube bar roller and a flat bar roller each of 400 mm diameter is very well suitable for optimum crumbling and reconsolidating. The intensive crumbling produces a fine shallow surface tilth which is ideal for volunteer and weed seed germination.
Especially for minimum tillage use, the use of the double roller as follow- ing implement is recommended.
In addition to tube bar- and double rollers there is a toothed packer roller available for the Smaragd 9 in difficult working conditions. Due to the simple scraper adjustment a perfect work without sticking even in humid and heavy soils is possible.
The use of the toothed packer roller provides a high bearing capacity and an optimal reconsolidating.
For direct seeding of intermediate crops during cultivation the Smaragd disc cultivator can be combined with suitable seed units. The seed is broadcasted by means of tubes. The following implement ensures a good crumbling and reconsolidating and the intermediate crops can germinate immediately and evenly.
Karat
When a tine of the intensive cultiva- tor Karat with overload safety device touches an obstacle, it swerves to the top and rear to be guided back to the working position immediately afterwards.
- The large tripping height, the over- load device and the tripping force of 550 kg per tine guarantee a smooth work even when working deep.
- Via the additionally integrated shear- bolt the LEMKEN Karat is perfectly protected even when a tine is stuck under a rock or root.
- The robust, forged beams and dura- ble pressure springs endure highest constant loads.
When the working depth of the mounted cultivator Karat is changed, the hollow discs adapt to the new working depth without re-adjustment.
- By means of a parallelogram the hol- low discs and the following rollers are always kept in position.
- With the folding cultivators Karat each roller segment is provided with a pendulum compensator. By that the rollers can level out soil uneven- ness and ensure constant depth guidance and smooth running of the Karat.
The semi-mounted cultivator Karat is equipped with a hydraulic depth adjustment as standard. With that it is possible to comfortably adjust the working depth stepless via the follow- ing rollers from the tractor cab.
- Here perfect operation quality is once more very important for LEMKEN: When changing the work- ing depth there is no need of re- adjusting the hollow discs.
- For exact depth guidance each roller segment is featured by a central pivot. Thus ground waves do not lead to a building-up of the cultivator.
Topas
The Tandem double roller, which consists of a scrolled tube bar roller and a flat bar roller each of 400 mm diameter is very well suitable From our long experience with the Terradisc tine and disc cultivator we achieve top quality cultivation with fewer tines and this has resulted for example in the 3 metre version of the Topas 140 being equipped with just 7 tines and producing ideal mixing and tilth.
The large clearance between tines considerably reduces trash blockages and enables total subsurfaces soil movement.
The short and compact design of the Topas ensures a positive centre of gravity.
The symmetrical positioning of the tines on the 140 mm square box section frame ensures an even draft which is particularly important when attached to the tractors front linkage.
Tine distance is adjustable to suit the following implement.
Each tine is adjustable to provide the optimum tilth, trash incorporation and penetration. The outer guide boards provide ridge free operation between passes and large inter-tine and under frame clearance enables operation in dense trash conditions.
Multi-adjustable depth wheels ensure an exact depth control.
An adjustable rear PTO enables the use of the original PTO shaft of the following implement to be used.
Pneumatic Seed Drills
Solitair
The double disc coulter with parallel suspension enables the independent adjustment of coulter pressure and seeding depth. The discs are equipped with wear and maintenance free tapered roller bearings, which are sealed by fixed covering caps. The upper area between the discs is covered so that there’s no possibility of stones or clods being caught there.
Through the staggered configuration of the double discs there are no blockages even with large amounts of mulch material.
The hydraulically driven fan speed can be steplessly adjusted and it is independent from the PTO shaft speed. The desired fan speed is easily achieved with a low tractor engine RPM variations in fan speed are reliably avoided when engine speed changes.
The seed distributors are mounted outside the hopper directly above the coulter bar. The pipes used are as short as possible with equal length which provides accurate seed placement and spacing. Seed pipes steeply run downwards which pre- vents seed blockages. The distributor head may be opened easily to enable inspection and cleaning.
