25 Simba SL
Operating Instructions
4.7 Adjusting Depth
To change the working depth it is advisable
to lift the machine clear of the ground so that
the rear roll linkage becomes loose. The
depth is changed by adding shims above and
below the collar on the depth control rod.
When the depth has been altered, lower the
machine into work and check operation. If
the depth change has been significant then
other settings could be affected. This could
be chassis pitch (front to rear) and disc angle
for the given depth.
A small amount of cultivation, eg. a 20 metre
run, should be carried out before altering
these settings to check whether they are now
suitable for the cultivation effect required.
These settings should be addressed
immediately to prevent too much
unsatisfactory work being carried out.
4.8 Work Instructions
Driving speed
The SL can be driven at speeds of up to 12
km/h.
This depends on the field conditions (type of
soil, surface trash, etc.).
Drive more slowly if the conditions are difficult
or a firmer finish is required.
Turning:
Before turning, the machine should
be eased fully out of work onto the
transport wheels while moving
forward. Likewise, it should eased
back into work once the turn has
been completed. Do not attempt to
turn the machine on the roll.
4.9 Parking the machine
In order to avoid damage as a result of
moisture, the machine should be parked, if
possible, indoors or under cover.
When manoeuvring the machine,
pay attention to your surroundings.
Ensure that nobody is in the
manoeuvring area (watch for
children!).
• Park the machine on level and solid ground.
• Raise the machine and lower the parking
stand.
• Lower the machine to the ground, ensuring
that it is stable.
When parking with the machine
unfolded, ensure that no load is
carried by the Terra-Grip tines.
This can lead to breakage of the
points.
• Disengage from the linkage and drive
forward slowly until the tractor is clear.
• Switch off the tractor.
• Disconnect hydraulic lines from the tractor.
