COVER STORY<br />
Top left: Rocks up to 50cm can be picked up<br />
Left: The Kivi-Pekka rock picker can be towed by a small tractor<br />
Above: Rocks enter the machine over a sieve and the soil is<br />
dropped back into the field<br />
Right: When the unit is lifted a grate cleans rocks and sieves<br />
soil<br />
The tines run the entire length between the sieve bars, keeping<br />
the sieve clean and preventing jamming of rocks.<br />
The lifting action is achieved with a hydraulic cylinder, which<br />
raises both rotors simultaneously.<br />
The rotors are locked into the top position with mechanical<br />
locks and can be set to the working or transport position from<br />
the tractor cab.<br />
Kivi-Pekka’s lifting drum transmission is mounted on its own<br />
frame, which allows the frame and entire lifting drum to rise<br />
up together, making it possible to pick up rocks with a 50cm<br />
diameter.<br />
A hydraulic pressure accumulator in the Flex Drum helps in<br />
raising the lifting drum when it comes upon large rocks, while<br />
the drum can also be raised into its up position manually using<br />
hydraulics.<br />
Another benefit of the Flex Drum’s suspension is that it dampens<br />
shocks to the sieve and tines, extending their service life.<br />
Thanks to the Flex Drum, there is no need to reverse rotation –<br />
the drum is simply raised to pick up large stones without having<br />
to stop.<br />
