Operation of the self-propelled implement

•
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:
•
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 deadman 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.
