Marking on the
gearbox
Description Use
P
Travel speed
(3. gear) Travel with the assembly on paved roads in flat terrain.
Rotary cultivation of soil - turning the soil into a very fine tilth, final loosening.
R
Reverse speed
(reverse gear) Reverse travel.
0 Neutral Starting the engine.
1
First gear Ploughing, passive soil preparation, travel with the trailer off-road and over uneven terrain.
Rotary soil cultivation - initial breaking up of virgin or hard soil, large lumps.
2
Second gear Travel with the trailer in easy terrain without undulation.
Rotary cultivation of soil - lighter type soils, breaking up heavier soils during subsequent ride
over.
Table 21: Marking of gears

Engage gears only when the engine is idling and the machine is at standstill; never during travel!
If the engine is running at higher than the idling speed the engine centrifugal clutch is engaged with the gearbox clutch plate, the cog-
wheels are turning and it is not possible to engage a gear. If it is not possible to engage a gear from the neutral “ 0 ” briefly increase the
engine speed (when in neutral) to make the gears in the gearbox turn and try to engage a gear again.
2.6.2 Latching the second and third gear
Latching the first and reverse gear in the gearbox when working with passive implements serves as an aid and safety element. This
measure prevents engaging the third gear instead of the reverse or the second gear instead of the first gear. The latching rod is on the left
side of the gearbox in front of the gear lever. When the pin is inserted in the deeper notch of the sleeve (see
Pict. 24), it is possible to
engage only these gears: 1 , 0 and R . When the pin is inserted in the shallower notch (see Pict. 23), it is possible to engage all of the
following gears:
2
,
1
,
0
,
R
and
P.

The gears latching must be done when the machine is standstill and with engaged neutral “0”.
2.6.3 Control of freewheels in the drive axle wheels
The wheels comprise freewheel hubs, where the freewheel latching finger allows four freewheel positions. The control lever is on
Pict. 27
marked with number 1 . The arrow on the lever indicates the direction of wheel rotation for positions FREEWHEEL FORWARD and
FREEWHEEL BACKWARD .
Figure no.27 Position Use
LOCKING
VAt this finger position the wheel is firmly connected to the hub. The arrow on the control lever
points either into the wheel centre of from the wheel centre out.
This position stands for straight travel forward or back. Turning with the assembly is however
difficult with this position.
FREEWHEEL
FORWARD
At this finger position in wheel turning forward the wheel is firmly connected to the hub. When
the wheel turns back or in situation when the wheel turns faster than the axle the bevelled
surface on the finger enables a partial disengagement of the finger from the notch in the hub.
This manifests on the outside as a clapping sound. The arrow on the control lever points in the
turning direction of the wheel (large circular arrow on Pict. 27).
This position is used for field work and for driving with one-axle trailers.
FREEWHEEL
BACKWARD
At this finger position in wheel turning back the wheel is firmly connected with the hub. When
the wheel turns forward or in situation when the wheel turns slower than the axle, the bevelled
surface on the finger enables a partial disengagement of the finger from the notch in the hub.
The arrow on the finger control lever points in the turning direction of the wheel (large circular
arrow on
Pict. 27 ).
This position is used for field work.
FREE
The finger is disengaged and the control lever is in the slanted grooving on the disc wheel lug.
The wheel can freely turn.
This position is used in the manual transport of the machine.
Table 22: Freewheel hub positons
To make the finger fall into the required position, it is necessary to drive a bit with the machine or move the machine by means of
handlebars from side to side until the finger falls into position. If disengaging the finger poses a problem drive the machine a bit to release
the finger from the engaged position.
2.6.4 Making a minimum radius turn with the tractor
The above-described control of freewheel hubs can be used to make a minimum radius turn during field work (ploughing, etc.)
