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 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.
KIVI-PEKKA stone pickers offer four working widths: 4m(13′), 5m(17′), 6m(20′) and 7m(23′). The machine width is chosen according to its planned usage rate and the stoniness of the soil, thus making it the right machine for the right application. The KIVI-PEKKA 5, KIVI-PEKKA 6 and KIVI-PEKKA 7 each have a wider lifting drum, which operates more efficiently with a higher volume of stones.
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 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. The standard tines are 12x45mm, which is ideal for use with the normal lifting drum (max. stone size 35 cm). Extra strong 13x50mm tines are used with Kivi-Pekka stone pickers equipped with a Flex Drum, whose maximum stone size is 50 cm. The tines are mounted on flexible rubber elements, thus offering lateral flexibility.
