2.3.3 Description of the machine and its parts
2.3.3.1 Gearbox
Gearbox DSK-317.1/S
(Pict. 2) consists of two castings, containing gearbox wheels nested in roller bearings. The upper case houses
the gears including the shift mechanism, and the lower case houses the worm shaft and the worm gear with hexagonal output shaft. The
gear changing is carried out with the gear lever 1 , located on the left side of the gearbox. The gears are locked in their positions by a
spring-loaded ball which falls into the corresponding shift gate recess. There is a connecting flange in the higher part of the upper casting
2 with clamping pins. The left side of the upper casting is provided with a locking handle 4 or all passive field work. The trailer towing
hitch is connected to the holes close to the dividing plane. The accessories driven by the gearbox output shaft (drive axle, ploughing
wheels, rotary tiller....), are connected to the output hexagonal shaft 5 and are secured with a retaining bolt and safety pin.
2.3.3.2 Drive axle
The drive axle TN-GLOBAL
(Pict. 4) consist of a half-shaft
1 with a hexagonal carrier inserted in the freewheel hub. The freewheel hub
is equipped with a locking finger for four freewheel functions (see text below). The locking finger is controlled by the control handle 2 with
an arrow indicating the direction of rotation of the wheel. The wheels are fitted with tyres 4 with tractor type V-tread and are screwed
onto the freewheel hub. Depending on the design the wheels may be fitted with a set of outer 5 and inner 6 weights. The drive axle is
connected by attaching the half-shafts 1 on the gearbox output shaft and securing it with retaining bolts and safety pin 3 .
2.3.3.3 Ploughing wheels
The ploughing wheels OK-GLOBAL
(Pict. 5) are screwed on the freewheel hub
1 in the same way as the drive axle wheels are. The
ploughing wheel 2 is a weldment of steel attachment plate and two circular profiles connected with welded on ploughing plates. The left
and right wheels differ from each other only in the angle the ploughing plates are welded onto the circular profiles. Connection to the
gearbox output shaft is identical with the drive axle.
2.3.3.4 Tiller implement
The tiller implement 1 is connected to the gearbox output shaft 2
(Pict. 13) instead of the drive axle half-shafts and is secured with
retaining bolts with safety pin 3 . The tiller implement with angular blades carries a basic type designation KUR (Pict. 16), and the one
with lanced blades carries a basic type designation KUK
(Pict. 17). The basic width of both tiller implements consists of two sets of blades
in a triple-star configuration 1 , identical for the left and the right side. Each triple-star shaped set is made of a carrier of welded hexagonal
pipe with welded-on flanges, onto which the tiller blades are screwed 2 . The blades are made of flat steel with forged sharp edge along
one side. The triple-star shaped set is put on the gearbox output shaft in the same way as the drive axle and secured with retaining bolts
with safety pin 3 . To achieve wider tillage the tiller implement width can be increased by adding single-star edge sets 4 , 5 . Each single-
star shaped set is made of a carrier of welded hexagonal pipe with welded-on flange, onto which the tiller blades are screwed. The driving
pin is inserted into a counterpart and is secured with a retaining bolt with safety pin 3 .
2.3.3.5 Protective cover
The safety protective cover 4
(Pict. 12) is made of sheet steel plates bent to required shape and welded together including welded on
steel feet and fastened with screws onto the gearbox side under the below the upper hitch screw.
2.3.3.6 Hitches and attachments
(Pict. 7) The upper hitch,
Hitch Z-01 1 is made of two welded together steel plates between which the shoulders of the hitch drawbar
fork are welded. Part of the hitch is a steel pin with a split pin. The hitch is screwed onto the casing with two screws, spring washers and
nuts.
The lower suspension attachment, Hitch BZN-002 2 consists of an attachment and a weight. The actual arm of the attachment is used
to connect all passive accessories and as the carrier of the 33 kg weight 3 . The attachment is made of two flat arms welded together and
a fork with holes welded on its end to connect an adjusting element or other passive implements. The front section of the attachment is
offset to allow easy installation of the 33 kg weight.
The tractor balancing is performed with the Weight carrier NZ-5/317 4 . It consists of a steel rod with a welded on fork used to mount
the weight carrier on the gearbox. The 5 kg weight 5 are slid on the steel rod and secured in position using the tightening handle.
2.4 Machine assembly

Request your dealer as part of pre-sales service how to set up the machine and briefing on how to use it!

Due to the weight of the machine, we recommend that the assembly is performed with the assistance of another person.

IMPORTANT NOTICE: Never lubricate the hexagonal driving surfaces on the output shaft of the gearbox, or the
internal hexagonal surfaces in the semi-axes or in the star-shaped tillers! Oil together with dirt creates a layer of
a very durable matter (similar to cement), which prevents easy removal of the drive axle or tiller implement
spacers!
48
The listed dimensions include the driving unit with guiding handles in optimal working position and with KUK-125. The width varies according to the applied working width of the
tiller implement.
