•
The implement is driven by two-wheel motors, which are controlled separately.
•
The single-wheel drive allows the wheels to rotate at different speeds and in different directions.
This makes it possible to drive very tight bends and, if necessary, to stop the machine quickly or
drive backwards.
•
As shown in Figure 7.2, a first steering lever (Pos. 1 or Pos. 3) and a second steering lever (Pos.
2 or Pos. 4) are arranged on the control panel on each handle.
•
If, for example, a left-hand drive is to be initiated, this can be done by actuating the first steering
lever (Fig.7.2, item 1) on the left handgrip (Fig.7.2, item 5). The more the first steering lever is
pulled through, the smaller the turning circle becomes, until finally the left wheel is blocked. The
right wheel is not affected in this steering maneuver and maintains its speed. If necessary, by
moving from the first steering lever to the second steering lever (Fig.7.2, item 2), the left wheel
can be moved in the reverse direction, whereby the turning circle can be reduced so that the motor
mower rotates about its own axis. There is a proportional behavior in both functions of the steering
levers. This means that the further the second steering lever is pulled through, the faster the left
wheel turns out of the blocked state in the opposite direction of travel.
•
When the two first steering levers (Fig.7.2, Pos.1 and Pos.3) are actuated at the same time, the
drive unit stops, while the second steering levers (Fig.7.2, Pos.2 and Pos.4) are in the reverse
direction at the same time emotional.
•
The control device with two steering levers on each side also constitutes a safety device, since it
is necessary to engage the two steering levers in a deliberate manner in order to change the
direction of rotation of the relevant wheel.
For sudden dangers moments:
•
In emergency situations, the operation of the two first steering levers (Fig.7.2, Pos.1 and Pos.3)
can be used to immediately stop the machine. The traction drive itself is switched off by the
subsequent actuation of the driving lever (Fig.7.1, item 1) in the horizontal position. Following this,
the two steering levers can be released.
•
Release the dead man switch (Fig.7.1, item 3). This shuts off the engine and brakes the wheels.
At maximum speed, the machine comes to a standstill after a few meters.
