Kivi-Pekka 4

Three-stage soil separation

The machine lifts the topsoil and separates stones from earth in three stages. (1) Stones pass onto a screen placed beneath the lifting drum; (2) they go into the hopper, while the sifted soil returns to the field; (3) the remaining soil is collected by a separate container behind the rear wall of the hopper and released at the moment of unloading. As a result, only stones end up in the hopper, and the valuable topsoil stays in the field.

Flex Drum — flexible drum for large stones

The lifting drum's drive runs along its frame, so the entire drum can move upwards. A hydraulic pressure accumulator allows the Flex Drum to “pass over” large stones instead of becoming blocked by them, while the suspension protects the screen and tines. The standard range of 2.5–35 cm extends to Ø 50 cm. The drum can also be raised from the cab to release a jammed stone, without leaving the tractor. The Flex Drum is available on models 5 and 6 (optional) and comes as standard on model 7.

Tank capacity and discharge height

A larger tank means fewer stops for emptying. Model 5 has 3 m³ and a capacity of up to 1000 kg/min; model 7 has 5 m³ and up to 1400 kg/min. On models 4–7, the hydraulic discharge reaches 2.9 m, so stones go directly into a trailer with sides up to 2700 mm or into a lorry, without being unloaded onto the ground first.

ISOBUS package — ultrasonic sensor and rotor protection

The ISOBUS version measures the working depth with an ultrasonic sensor and maintains it automatically. In the event of a jam, the machine relieves the rotors by itself and raises the Flex Drum, then returns to work once the blockage clears. At the headland, a single button is enough: the automation lifts the machine and stops distribution. The package is available only in versions with the Flex Drum.

Glacial soils

Farms on glacial soils, where stones “come up” out of the ground after every winter and damage seed drills, combines and tyres. Model 3.3 is for narrow specialist crops and landscape management (tractor from 60 hp), model 4 is an economical entry point (from 70 hp), model 5 suits medium-sized areas (from 80 hp), and model 7 is for large areas and contract services (from 100 hp).
