work progress

1

The outer border of the field to be worked is first worked using radio remote control.

2

The area lying within this outline is defined as an area to be worked.

 

 

3

The user selects from the proposed travel pattern strategies:

1)
The fastest travel pattern within the defined field calculated by the assistance system itself.

2)
Travel direction and travel pattern determined by the operator.

 

4

  1. The machine calculates the travel pattern according to the selected strategy and starts the work.

1)
First, two further passes are mowed along the defined outer border in order to create space for turning manoeuvres.

2)
Thanks to the assistance system, the defined field is worked semi-autonomously.

 

5

The operator must monitor the work at all times and stop the machine by radio remote control in case of emergency.

6

The machine will stop after completing the work.

7

The operator then drives the machine off the field by radio remote control.
