2. INTENDED USE

The compact KRUK disc harrow is a universal tool for the cultivation of the top layer of soil

to the depth of 5 cm to 15 cm. It is designed for use after harvest and before sowing following

ploughing or in soil cultivation without ploughing, when the vegetation remains are not covered but

mixed with the top soil layer (i.e. mulched). It may be used on all types of soils including those with

stones thanks to the use of elastic suspension of the harrow discs. The harrow allows for opening

and mixing of the soil and in connection with the packer also for packing and compressing of soil.

Due to the resistance to clogging the harrow is well suited for the cultivation of tall stubbles which

remain after the harvest of crops and corn and for cultivation of aftercrops intended to be used as

fertiliser.

• check whether the discs and packer rotate freely by rotating them by hand,

•lubricate the elements of the machine in accordance with the guidelines specified

in section 8.5.

The machine's hydraulic system is filled with Renolin VG46 hydraulic fluid manufactured

by FUCHS. It is allowed to mix it with the hydraulic liquid with the oil from the tractor's hydraulic

system.

8.2 COUPLING THE MACHINE TO THE TRACTOR

To safely and securely couple the machine to the tractor it should be placed on a firm and

level ground.

To couple the machine to the tractor it is required to perform the following actions

• reverse the tractor to a distance which allows to couple the machine with the tractor's lower

hitch,

• attach the upper hitch of the 3 point hitch to the machine and remove any play,

• attach the hydraulic lines of the machine to the tractor's external hydraulic system,

• raise the machine,

• check the leaktightness of the machine's hydraulic system, the hydraulic lines may not be

bent or damaged,

8.3 MACHINE ADJUSTMENT

8.3.1 ADJUSTMENT OF THE HARROW DISKS' WORKING DEPTH

The working depth of the harrow disks may be adjusted using the tractor's three point hitch

or the mechanical or hydraulic shaft adjustment mechanism.

In case of the mechanical adjustment the depth is adjusted by changing the length of the

turnbuckles.

In case of hydraulic depth control the adjustments are made using the hydraulic control

levers inside the tractor's cabin by changing the number of pressure plates of the actuators placed on

the piston rod (fig. 4 - item A).

8.3.2 WORKING DEPTH AND TINE ANGLE ADJUSTMENT

The adjustment of the tine working depth is performed using pins placed in appropriate

openings in the plough frog secured with a cotter pin (fig 4. - item B).

The angle may be adjusted using the lower scraper attachment pins (fig. 4 - item C).
