Effects of Using GNSS Guidance for the Non-skilled Operator to Improve the Accuracy and Efficiency of the Tedding Operations

Abstract

We investigated the tedding operation accuracy when a non-skilled operator worked on a skilled operator’s advice or with GNSS guidance. The non-skilled operator using a skilled operator’s advice could drive a tractor with the same accuracy of the skilled operator. When the non-skilled operator used GNSS guidance, the overlapping area was 26 % more compared to driving on a skilled operator’s advice, but all area was operated.

We measured the travel distance and work time of the nonskilled operator with and without GNSS guidance when the operator performed tedding in a 4.5 ha field. GNSS guidance reduced the driving distance by 33 % and the work time was 16 % lower. Thus, GNSS guidance could improve the work efficiency of a nonskilled operator.
