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.
Kivi-Pekka 3-phase soil sieving system
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.
The 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.
Strong tines and auxiliary springs
All tine sizes give way sideways to prevent blockages. No backwards rotation is hence required. The 12×45 tines are particularly durable and contribute to extended maintenance intervals. All tines are fitted with auxiliary springs and suspended with rubber buffers.
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.äänimerkillä, mikäli joku näistä lakkaa pyörimästä.
