2.3 Basic information
2.3.1 Use
Gearbox DSK-317.1/S used in drive axle assembly creates small one-axle tractor which can be combined with one-axle braked trailer
for transporting load. For passive soil cultivation the gearbox can be combined with an attachment for connecting passive implements. The
small one-axle tractor wheels can be easily replaced with soil loosening implements or ploughing wheels to cultivate the field with a plough.
The output shaft is supported on roller bearings and the casing is in this place fitted with a special seven-lip seal that prevents dirt from
entering the gearbox and oil leaks from the casing. The lower part of the gearbox is waterproof and can operate submerged in water or
mud up to the dividing plane. This feature can be used for example in the cultivation of flooded rice fields.
Gearbox DSK-317.1/S features an upgraded output shaft, which does not allow the use of axles and tiller implements with the axial pin
(drive axles TN-01 to TN-05, cultivators AKY-357 and AKY-358). With this gearbox it is possible to use only axles TN-GLOBAL and
cultivators KUK/KUR . Other accessories for the gearbox are identical to the original small one-axle tractors TERRA/VARI. Any four-stroke
engines supplied by VARI a.s. can be coupled as drive units.
2.3.1.1 Drive axle TN-GLOBAL
Drive axle TN-GLOBAL is used to provide travel on paved and to a limited extent also on unpaved roads. Half-axles are mounted on the
output shaft of the gearbox and secured with locking pin with safety catch. The drive axle is supplied equipped only with outer weights as
standard. To improve adhesion, it is possible to mount add-on inner weights. When using the drive axles we also recommend to fit the
gearbox with all possible weights (33 kg at the lower attachment BZN-002 + 2pc of 5kg on weight carrier NZ-5/317). This will increase the
pulling power of the axle and improves terrain passability.
2.3.1.2 Ploughing wheels OK-GLOBAL
The ploughing wheels OK-GLOBAL are optional accessories designed for ploughing. They are mounted on the output shaft of the
gearbox in the same way as the drive axle. Ploughing wheels are mounted on the axle’s freewheel hubs in place of the tractor V-tread rim
wheels. Their diameter is such that in use with the lower attachment the attached accessories are at the correct height above the ground.
Use the add-on weights to reach the required weight and balance of the machine.
2.3.1.3 Tiller implements KUK/KUR
Tiller implements KUK/KUR are put on in the place of the drive axle onto the output shaft of the gearbox always in such a way that the
blade sharp edge on each star-shaped set indicates the direction of rotation. Slowing down in forward motion and to determine the depth of
the soil loosening is achieved with the use of a share holder N-3 with share, which is attached to the upper hitch Z-01 and secured with a
pin. The guide wheel VK-GLOBAL is used to provide easy transport of the tiller implement assembly. The guide wheel is mounted by
means of screws in the holes in the front part of the gearbox casting. Guide wheel is used only for transporting the tiller implement
assembly to a field. During work the guide wheel is dismantled or put upside down in the holder so as to face upward.
