Kivi-Pekka 13’ Rock Picker. By using a Kivi-Pekka stone picker, you will be able to avoid causing wear and tear on your other farming machinery. The Kivi-Pekka stone picker will also help increase your crop yield, as there will be no stones to restrict the cutting height when harvesting, prevent harvesting or damage your machinery.
The machine is customized and manufactured according to the customer’s specifications. The KIVI-PEKKA is suitable for use by small co-operative groups and contractors, thanks to its durability and speed. In addition to field work, the KIVI-PEKKA can also be used for land clearance, road renovation and foundation work, golf courses and landscaping.
The Kivi-Pekka stone picker does not require a high towing capacity (70 hp) or hydraulic capacity (20 l/min.) from the tractor. You can run the stone picker with a small tractor, thus saving on fuel and costs and keeping your larger tractors available for jobs requiring more power.
The KIVI-PEKKA Flex Drum makes it possible to collect larger stones than when using the standard lifting drum. The lifting drum transmission is mounted on its own frame. This allows the frame and entire lifting drum to rise up together, thus making it possible to pick up stones 50 cm(20″) in diameter. The hydraulic pressure accumulator in the Flex Drum assists in raising the lifting drum when it comes upon a large stone. The drum can also be raised into its up position manually using hydraulics. The Flex Drum suspension dampens shocks to the sieve and tines, thus extending their service life. Thanks to the Flex Drum, there is no need to reverse rotation – the drum is simply raised to pick up large stones without having to stop.
Kivi-Pekka is equipped with strengthened drive belts, and power is transmitted to the lifting drum via straight drive belts, which reduces the power requirement. The belts do double duty as an overload protection mechanism, while also absorbing the shock from the stones that come into contact with the machine, thus preventing it from affecting the tractor through the transmission. The belts are highly resistant to wear and tear and require very little maintenance. Because the drivetrain contains no expensive parts that need replacing, the operating costs of the Kivi-Pekka stone picker are kept low.
Kivi-Pekka sieves soil in three phases:
– Stones enter the machine over the sieve, which is located underneath the lifting drum.
– When the stone is dropped into the stone tank, the accompanying soil drops through the bottom grate and back into the field.
– The soil container, which is located behind a grate in the back wall of the Kivi-Pekka stone tank, sieves the soil during tipping.
Kivi-Pekka’s tines are the result of years of product development. Extra strong 13x50mm tines are used with Kivi-Pekka stone pickers.
