Durability
The durability of the machine has been achieved as a result of progressive product development over the past 35 years. The right materials and the best components keep running costs low.
Flex Drum lifts heavy stones
The lifting drum’s power transmission is mounted along the drum frame, allowing the frame and the entire lifting drum to yield upwards, which makes it possible to lift stones 50 cm in diameter. Because of the Flex Drum’s hydraulic pressure accumulator, the drum passes over any large stones it comes into contact with. In addition, the drum can be raised into the top position with the hydraulic system, allowing any jammed stones to be released.
The Flex Drum’s suspension system protects the sieve and tines against the contact with stones, thereby extending their service life. Thanks to the Flex Drum, no backwards rotation is needed, as the drum can be lifted up and a large stone picked up without stopping.
Extra strong tines and auxiliary springs (Flex Drum)
All tine sizes give way sideways to prevent blockages. No backwards rotation is hence required. The 13×50 Flex Drum tine is particularly durable and contributes to extended maintenance intervals. All tines are fitted with auxiliary springs and suspended with rubber buffers.
Soil collecting
Soil collection allows the topsoil to end up back in the field. Cleaned rocks can be used in construction or road building, for instance.
Kivi-Pekka separates the soil over three stages:
1. Stone enters the machine over the sieve located under the lifting drum.
2. Stone is carried to the tank, and the soil in the sieve structure is released back to the field.
3. Any left-over soil slides into a separate container located behind the back wall of the stone tank, and gets released at the tipping stage.
Sieve
The welded sieve is made of special-alloy steel and is available with different spacings. The tines run between the sieve bars the entire length, thus keeping the sieve clean and preventing jamming of rocks.
Hydraulic lift
The lifting action is achieved with a hydraulic cylinder, which raises the rakes simultaneously. Mechanical locks secure them into the top position. The operator is able to position the picker in working or transport position from the cab.
Optional accessories
ISOBUS control makes work easier and more effective
Stone pickers with ISOBUS control measure the working depth by means of an ultrasound sensor and adjust the depth automatically. If stones begin to pile up too fast, the machine automatically lightens the rotor and raises the Flex Drum. Once the congestion has cleared, the rotor and lifting drum return automatically to the original position. In the headland, the automatics lift the machine and pause the PTO at the press of a button. The automatics also lift the machine when the tractor reverses or the PTO is disengaged.
Working with an ISOBUS stone picker is easy and lets you work long days without getting tired. The automatics also prolong the service life of components by preventing excessive wear. In addition, the ISOBUS terminal displays service reminders and working time, which is a big help for contractors and users who share equipment.
Rotation quard
When operated in dusty conditions, the rotation guard monitors the operation of the rotors, the lifting drum and the main drive PTO shaft with sensors. An auditory alarm in the tractor cab alerts the operator if any of these stops turning.
