Description of the Machine
The KULTIS cultivator is used for inter-row cultivation of maize and sunflower growth with
concurrent additional liquid fertilization.
Its frame is semi-mounted; the machine is mounted in the arms of the hydraulics of the
pulling tractor. It has not control in the cross direction. The number of processed rows is 6 or 8;
the inter-row spacing is 650
– 750mm.
The machine consists of a frame which is fitted with weeding units, a chassis, a tank for
the fertilizer with a pump and application distribution. Furthermore, there is hydraulic control
system for folding the arms of the frame and the chassis.
3.3.1. Frame
The frame consists of a three-piece carrier of the weeding units; there are connecting pins
for the pulling vehicle in the front and a holder for the tank with the applied fertilizer with an
operating platform in the rear. There are holes for securing the side arms in the working or
transport position using pins in the place where the frame is divided.
3.3.2. Weeding Units
The weeding units are designed with a parallel link hitch. There is a shank with a flat-
cutting V-string sweep with the width of 250mm in the rear part of the unit. There are application
pipes for the distribution of the liquid fertilizer in the rear part of the shank.
Furthermore, there separator disks located on the shanks in the rear part of the unit that
are adjustable in both vertical and horizontal direction. The separator disks separate the strip of
the processed soil by a weeding tine from the row. At the same time, it acts as a shield that
prevents damage to the plants in the row caused by the soil from the tine.
The weeding unit may get clogged even when the separator disks are set to the maximum
width when cultivating growth with a high amount of weeds.
The frame of the tine is connected to the unit by two screws M16x70. They are shear
screws in order to protect the frame of the weeding unit from damage caused when the tine hits a
solid obstacle or gets clogged.
There is a feeler wheel with adjustable working depth on the handle in the front part of the
unit.
In the centre of the parallel link hitch, there are shock-absorbing springs or hydraulic
plunger located on pins. They stabilize the weeding unit in the vertical direction and ensure
terrain tracing.
The weeding units are connected to the frame by clamps. When rearranging the inter-row
spacing, release the clamps and change the position of the weeding unit to the required distance.
3.3.3. Chassis
The chassis consists of two pairs of travelling wheels that are adjustable in relation to the
frame. There are two wheels allowing mechanical setting of the height of the frame above the
surface, located on the axles in the front of the frame in the direction of drive. There is a chain
drive of the metering pump for the fertilizer on one of the wheels.
There are travelling wheels located in the rear part of the frame on hydraulically controlled
axles.
