4. OPERATING MANUALS
Before use you must read the operating manuals precisely!
The operating manuals will introduce the MAESTRAL and also warn you on
particularity to which you should pay special attention. Because the MAESTRAL is a
working machine what requires also suitable knowledge, qualification to handle with
motor machines. Consideration of the manuals assures safety and faultless operation
of the machine. You will also avoid possible costs because of mishandling or wrong
maintenance of the machine. In that case the machine will be useful help by various
works. In case of buying of spare parts, please see the
-3-
Page 4
catalogue of spare parts with marked spare parts. In case of machine trouble
please go to nearest authorised service of Tovarna Muta.
WARNING!
When buying the machine please demand confirmed
indemnity bond from the dealer. With confirmed indemnity
bond you carry guarantee intervention into force. When
ordering spare parts please state the machine type, year of
production and code of spare part you are ordering.
5. USE OF MAESTRAL
Motocultivator MAESTRAL is multipurpose machine, in combination with
various attachments is performing particular works like cultivating of land on the
field or in the garden with attached rotary tiller, mowing – haymaking with
attached mowing system and cutter bar, ploughing, transport …
Superiority of the machine is multifunctional, it can perform various works, it
is easy to handle with, light machine regarding to it’s functionality.
Motocultivator MAESTRAL we can use together with attachments, made by
Štruc Management, adapted for use on this machine.
Regarding to the work we adjust also the speed of work. MAESTRAL has a
lot of possibilities in both directions. For harder work conditions we can choose
lower gear, for easy work we can choose higher gear. The work can be done more
efficiently and safe.
6. DESCRIPTION OF INDIVIDUAL FUNCTIONS OF THE
MACHINE
The handle levers on the machine we will describe in position of machine,
when the machine is ready for mowing, that means that in front of you is first the
engine thereafter is gearbox (Pic. 1). For proper functioning of the machine all the
levers should be adjusted properly, only in that case the work with machine is
easy and correct.
Handle bar with steering functions
- adjustment of working height of handle bar you achieve with pushing of lever
No.7 till first position, then raise or lower the handle bar regarding your body
height and attachment you are using (Pic.2)
adjustment of side deviation of the handle bar you achieve also with pushing
of lever No. 7 but till second position then you turn the handle bar to right or left
side (Pic. 11). After releasing the lever the cork should stuck into the

groove of dividing part and hole of the thorn, so that the handle bar remains in this
position. For height regulation there are 7 positions available, side deviation has one
position on the left and one on the right side.
- for some works like tillage, transport with trailer, cultivating and ploughing the
machine has to be adjusted properly. That means you must turn the handle bar for
180 degrees. In that case you must dismount all three steering levers. To do that you
must pull out with hand all the corks (Pic. 16). You dismount the levers, rotate the
handle bar and mount the levers back into place (put back the corks!). Check if the
handle bar is locked! For side deviation the procedure is the same like for mowing
position (Pic. 11).
Clutch lever with safety switch
- clutch lever is mounted together with safety switch which prevents running of the
machine when the clutch lever is not pressed. This prevents eventual accidents by
unintentional release of clutch lever (the engine stops). Mechanical principle of
safety switch is blocking the clutch lever when the safety switch is not pressed. By
starting of the motor you must press the clutch lever first and then block the clutch
lever with the button inside the clutch lever holder. Starting of motor is possible
only when the clutch lever is pressed! Start the motor according to enclosed
manuals and pictures for motor.
- when the motor is running you can begin with work. The clutch lever should be used
together with lever of safety switch. When both levers are pressed (Pic. 3) you can
change the gears, drive direction or activate driven attachments (Pic. 8). When all
the levers are in correct position you begin with releasing of the clutch lever slowly
but you are still pressing the lever of the safety switch, which must be pressed all the
working time.
- the clutch is dry conical (optionally is multidisks). The clutch is adjusted correct,
when the clutch lever has 2 – 5mm of free movement.
WARNING!
M
OTOR IS NOT RUNNING WHEN THE CLUTCH LEVER AND THE
LEVER OF SAFETY SWITCH ARE NOT PRESSED (PIC.
3)
Brakes
- the brakes are by machines with differential made separately for left and right wheel
and are a support by steering – rotating the machine. Both brakes (left and right)
must be adjusted equal. Locking of brakes – parking position we achieve with
pushing of locking tonguelet into the groove, than remains the brake lever in pressed
position. You unlock the brake with pressing the brake lever again (Pic. 4a and 4b)

WARNING!

HEN THE DIFFERENTIAL LOCK IS ACTIVATED (PIC. 5B) BRAKES
ARE NOT WORKING SEPARATELY FOR LEFT AND RIGHT WHEEL – THERE
IS NO STEERING FUNCTION
!
Gear changing
- there are 7 gears available on MAESTRAL – 3 forward and 3 backward. Fourth
gear is possible only when the motor is in front and serves only for transport with
trailer or moving the machine to the working place. When we rotate the handle
bar the fourth gear is blocked! We choose the desired gear with lever on the left
side – No.8, the moving direction we choose with lever forward – backward on
the right side of the machine – No.5.
When changing gears you must use the clutch! Reduce the gas and
choose the desired gear with the lever (Pic. 8).
Mounting the attachments
- you mount the attachments on the basic machine with two (2) nuts (Pic. 13, 20)
- when mounting the machine must not run (safety switch released)
- when activating the attachments with lever 5 you must use the clutch (Pic. 8)
- by attachments with quick connection you change the attachments with pulling
out the cork and than change the attachment

SPECIAL WARNING!
BECAUSE OF MOST FREQUENT USE FUNCTION OF
CHANGING THE MOVING DIRECTION FORWARD –
BACKWARD, YOU MUST HANDLE WITH THIS LEVER
CORRECTLY. WE DO THE CHANGING AS FOLLOWS (SHOWN
ON PICTURES 7,8,9 AND 10): YOU MUST REDUCE THE GAS,
PRESS THE CLUTCH LEVER AND MOVE THE LEVER FORWARD –
BACKWARD GENTLY. WHEN YOU ARE SURE, THE LEVER IS IN CORRECT
POSITION, SLOWLY RELEASE THE CLUTCH LEVER AND ADD THE GAS
WHEN NECESSARY. WHEN CHANGING THE MOVEMENT DIRECTION THE
SPEED OF THE MACHINE IS NOT CHANGED.
The correct adjustment you can check on the gearbox, where the limiter is
mounted. The limiter is adjusted correct when the gear change lever leans onto
limiter just before end position (app. 1mm). In that case we avoid burdening and
wearing out in the gearbox.
Differential lock
- it activates with pulling of the lever backwards, it should remain in this position.
You use the differential by hard work, when both wheels traction is required or
when one wheel slips (on slopes for example) (Pic. 5a, 5b)
WARNING!
A
CTIVATING OF DIFFERENTIAL LOCK WITHOUT CLUTCH IS NOT
ALLOWED WHEN THE MACHINE IS OPERATING OR WHEN FULL GAS. BY
REDUCING THE GAS YOU CAN ACTIVATE IT WITHOUT USE OF THE
CLUTCH
.

7. MAINTENANCE
Maintenance manuals for the motor are in the motor Operating manuals. We
recommend you to check the oil level regularly every 20 hours (oil gauge) (Pic.
14). Change oil every 100 working hours or once in a season!
When changing oil the machine must be warmed up. Pour the oil out through the
hole on the bottom of the gearbox by unscrewing the oil screw. Pour in the oil
quality SAE 90 1,7l.
After the work clean the machine of earth, grass or similar dirt. When storing the
machine for longer time, grease metal parts with oiled mop.
We wish you successful work with machine MAESTRAL!
