Power harrows Zirkon - LiveUpdater

Efficient seedbed preparation

The soil is the most important resourcein productive agriculture. Choice of theprimary cultivation procedure, for theparticular location, and optimal use oftechnology, help retain the long-termprofitability of the soil. Another importantfactor for a successful harvest –irrespective of the cultivation procedure– is the preparation of seedbeds.The objective here is to prepare the soilso that the seeds can quickly germinateand efficiently grow. The prepared soilstructure should remain stable rightthrough to harvest.After primary soil cultivation the land isprepared for optimum plant developmentby the preparation of seedbeds.The seeds which have been sown andare germinating in the soil requirewater, heat and air to develop. The surfacesoil should be soft enough for theseedlings to grow through. The areaunder the seeds should be reconsolidatedto aid capillary action and watersupply to the plant. These factors areoptimised in a well prepared seedbed,thereby ensuring the basic requirementsfor a good growth rate.Seedbed preparation must also performthe following tasks:••The surface left by the primary soilcultivation must be levelled to createuniform conditions for sowing.••The tools on a machine used for thepreparation of seedbeds, e.g. powerharrow tines, must break up clods,lumps and crumbs. However, it is notjust a queston of generating the correctaggregate sizes. Even clod distributionin the seedbed and the longtermstructural stability of the soil arealso important for plantdevelopment.••The soil must be cultivated to a consistentworking depth.••An adequate reconsolidation of thesoil under the seeds is essential foroptimum soil compaction to ensurethat the seedlings are supplied withwater during the first growth phase.• • The pore volume, in the topsoil, mustbe large enough to ensure an adequatesupply of water and air to theplant roots.

Zirkon – perfection in many variationsIt is becoming ever more important toadjust the intensity of the seedbedpreparation to the prevailing field conditions.Practice shows that the powerharrow is a very versatile and efficientdevice and therefore best performs thispreparatory task.To ensure optimum seedbed preparation,the working parameters of theZirkon power harrow from LEMKEN canbe perfectly adjusted. Whether shallow,quick and extensive, or deep andintensive – it is only neccesary to setthe specifications such as workingdepth, rotor speed, tine position andforward drive speed for the requiredsoil cultivation. The Zirkon power harrowproduces an intensive mixing andcrumbling action down to a workingdepth of approx. 15 cm. The active toolswill prepare an optimum seedbed inpractically all soil conditions, even incompacted, dry and hard or heavysoils. The use of the power harrow inagriculture is therefore acquiringgreater importance today. In combinationwith other machines many workprocesses can also be completed morequickly and economically.both in conventional and in conservationcultivation procedures and can beused both in a rear and front-mountedposition.The Zirkon power harrows are availablein different working widths anddesigns:••Zirkon 8: The mounted, entry-levelmodel in working widths from 2.5 to4 metres non-folding format.••Zirkon 10: The high-performancemounted, rigid power harrow with a3 or 4 metre working width.••Zirkon 10 K: At working widths from 4to 6 metres the mounted power harrowcan also be hydraulically foldedto a transport width of 3 metres evenin combination with the Solitair 9 Kseed drill.• • Zirkon 10 KA: The semi-mountedpower harrow in working widthsfrom 4 to 6 metres. When combinedwith the pneumatic Solitair seed drillfrom LEMKEN, is a powerful combinationfor demanding arable farming.The Zirkon power harrows fromLEMKEN best meet the high demandsof a modern arable farm. They are suitablefor very high continuous loads

The quietest andsmoothest runningmachine in its classSimple replacement oftines by the quickchangesystemChange of rotation direction –correct tine position simply &quicklyEach four tine carriers per metre workingwidth are arranged with a minimumoffset to each other so that thetines of the Zirkon power harrow canwork in succession to each other.••A constant force flow of the tines inthe soil is achieved even underextremely difficult conditions.••This arrangement creates verysmooth running characteristics and auniform load on the tractor PTO.The advantages of the quick-changesystem are offered as standard by theZirkon 10, optionally by the Zirkon 8.The knife tines have sharpened cuttingedges on both sides.••Each pair of tines is attached to thetine carrier with a safety plug. Tinescan be changed simply and quickly.••The special hardening process makesthe knife tines particularly wearresistantwithout becoming brittle.••Hard facing in the main wear areassignificantly extends the service lifeof the knife tines.The DUAL shift gears from LEMKENfacilitate not only changing the speedof the rotors but also the direction ofrotation of the rotors.••The change in the direction of rotationenables the knife tines to be setto “grip” or “drag”.••When set to “drag”, the tines have abetter levelling effect and are particularlyusefull in stoney conditions, asstones are pushed into the ground.••In the “grip” position the tines aid soilpenetration and prove themselves inmulch sowing through the intensivemixing of soil and vegetation. Fineearth is conveyed into the area of theseed placement. Large crumbsremain on the surface and reducecapping and erosion.
