VARI GLOBAL
2.4.1 Gearbox
First attach, according to (Pict. 6) onto the square-end 1 of the shift gate the sheet metal arrow 2 indicating which gear is engaged,
followed by the gear lever 3 , which must be secured against coming off with the split pin 4 . Check if the tightening handle ( 3 on
Pict.
2) is unscrewed enough to ensure that its threaded end is not in the way of mounting the driving unit.
2.4.2 Small one-axle tractor assembly
2.4.2.1 Hitch Z-01
1 on Pict. 7: is fitted using 2 screws with washers and nuts in the holes in the rear part of the gearbox. Tighten the bolted connection
well! The single axle trailer is connected to the fork of the hitch using a pin with a split pin. The pin must be always secured with the
split pin so it does not fall out.
2.4.2.2 Drive axle TN-GLOBAL
Pict. 9: set the finger of the freewheel in the position
LOCKING (see
Pict. 27
A ). Insert the spacers’ hexagonal driving pins 1 of the
driving axle TN-GLOBAL into the wheel hub’s hexagonal holes 2 , slip on the washer 3 , screw on the lock castellated nut 4 and tighten
it well – torque 200 Nm . Insert the split pin 5 and bend out its ends.
Pict. 10: the drive axle is attached over the hexagonal
1 output shaft of the gearbox. When attaching make sure that the hole in the
half-axle spacer 2 coincides with the hole in the shaft of the gearbox so that it will be possible to push through the holes the retaining bolt
with safety pin 3 . Always snap the safety pin around the retaining bolt so that the bolt does not fall out during operation! The V-tread on
the tyre must be in the travel direction when the machine is travelling forward.
Assemble the drive axle on the tractor by the following procedure:
1. Put the left wheel 5 on a firm and level surface with the spacer facing upwards.
2. Turn the gearbox 6 into a horizontal position. Insert the left part of the gearbox output shaft into the wheel spacer. secure with
the retaining bolt and safety pin 3 .
3. Fit the right wheel 7 with the spacer on the right side of the of the gearbox output shaft. Secure with the retaining bolt and
safety pin 3 .
4. Turn the tractor on its wheels. Before mounting additional accessories, use the support leg ON-1 or connect the tractor to the
one-axle trailer to ensure its stability.
2.4.3 The additional inner weights assembly
The additional inner weights can be added to improve adhesion and to increase the total weight of the small one-axle tractor during soil
cultivation. When installing inner weights, first remove the two (out of four) screw connections for the outer weights, hub and wheel rim.
Put one add-on inner weight 3 on the inner part 2 of the wheel rim 1 and using the screws M10x140 4 wiht nuts M10 5 and lock
washers 6 (included with the add-on outer weights supply) screw the weight on the rim. Do not tighten the screws yet. Do the same with
the other add-on outer weight for the same wheel. Finally, tighten all screws to the torque of 48 Nm , preferably in a “cross” shaped
pattern. Repeat the procedure with the other wheel of the drive axle.
2.4.4 Ploughing accessories
For soil cultivation using passive accessories the small one-axle tractor must be provided with add-on attachment BZN-002 ( 2 shown
on Pict. 7) Attach the lower attachment with two M12 screws in holes in the lower casing. The attachment feet with holes are directed to
the back towards the operator. Tighten the bolted connection well! The attachment arms are provided with several mounting holes. For the
passive accessories mount the lower attachment as shown so that the holes of the fork are in a top view behind the upper hitch. The
passive accessories are attached to the adjusting element
50 NT-3 .
Balancing the machine to work in the correct position is achieved with the use of the additional weight carrier NZ-5/317 ( 1 on Pict. 8).
It is attached with two screws M10 2 to the feet provided with holes in the front upper part of the gearbox.
2.4.5 Ploughing wheels
The ploughing wheels OK-GLOBAL are attached on the freewheel hubs of the drive axle using four screws M10 with nuts and washers in
place of the tractor wheel rims. The wheels are attached from the inner side of the hub, i.e. from the gearbox side (Pict. 5). Tighten the
bolted connection well!
2.4.6 Rotary cultivator assembly
If the small one-axle tractor is fitted with attachments BZN-002 and NZ-5/317 , it is necessary to remove them before attaching the
tiller implements.

Always remove the attachment (the lower suspension)! There is a danger of damage to the gearbox and the tiller
implement blades.
Observe some important recommendations when assembling the tiller implements:

Attach the sharp edges of the blades on the gearbox output shaft so as to have them always at the front in the direction of
rotation 51 .

The blade points at the gearbox must be always against each other! If it is not so the rotary tiller is jumping and is difficult to
control.

The star-shaped sets and blades on them are always turned against each other by 45° in relation to the row before them. The
blade points thus form a continuous spiral for easier penetration into the soil. Therefore observe this angular setting by 45° also
when attaching additional single-star edge sets on wider tiller implements.
50
Connections and setting, see the pertinent Instructions for use.
51
When looking at the gearbox from the left side of the gear lever the output shaft rotates in forward travel counter-clockwise (to the left).
