The newly released Zirkon power harrow joins the impressive line-up of machinery at Te Aroha Tractors


The newly released Zirkon power harrow with modular design is part of the impressive line-up of machinery at Te Aroha Tractors. The Zirkon power harrow has been a part of the Lemken product range for a long time as a solo machine as well as in combination with a seed drill.

The top-of-the-range model of the Zirkon range has been revised and relaunched with a modular concept. The Zirkon 12 now offers a greater choice of gearbox and tine equipment, with a choice of two types of central gearboxes offering the proven rotor speeds of 330rpm and 440rpm for the PTO speed of 1000rpm.

Farmers and contractors who don’t require a regular exchange of the rotor speed may choose a new angular gearbox with two manually changed gears as an economic solution.

The new angular gearbox is available for the foldable versions for tractors up to 320hp (235kW). The revised Dual-Shift gearbox provides gear selection via a lever as before. It can be used for tractors with up to 408hp (300kW).

The new arrangement of the front PTO connection and the rear shaft connection also provides a smoother running of the shafts. The Zirkon 12 also features the change of the direction of rotation, allowing quick change of the tines from working in drag to grip position or vice versa.

Offering a selection of bolted tines and quick-change tines, the bolted tines are directly bolted to the rotor and come as standard. For the quick-change tines, holders are bolted to the rotors, which house the tines. This feature is an option and the power harrow can be upgraded or exchanged any time.

Many smaller but useful improvements have been integrated in the new range of power harrows. The transport security of the folding versions can now be hydraulically unlocked. Depth adjustment and the guidance of the side plates now provide improved adjustment.

The three-point linkage connection point has been adapted to suit tractors with larger category linkages. For the first time, Lemken offers hydraulic depth adjustment for the Zirkon 12. This means the driver can conveniently adjust the working depth to changing soil conditions from the driver’s seat while working. 

The three-point linkage provides an increased lifting power of up to 3000kg.
Te Aroha Tractors are a regional dealer for Lemken cultivation products, servicing Waikato, and stocking a full range of wear parts for all Lemken cultivation equipment.
