CONTOUR SWATHING
Some fields require Contour Swathing for application of fertilizer, chemicals, or other agricul-
tural maintenance. If a field has contoured terraces, Contour Swathing may be required for
swathing to follow the contour of the terraces. Some fields may have an irregular shape,
which requires Contour Swathing for reasonable coverage.
When Contour Swathing is used, each swath (except the first) is based on the previous swath.
This allows any irregularities in one swath to be accounted for in the next swath. For example,
the operator may have to drive around a tree or ground feature in the field. Guidance for the
next swath will follow the path taken by the operator when driving around the tree or ground
feature. Contour Swathing can be referred to as ‘relative’ swathing. This is because each
swath is ‘relative’ to the previous swath. Other parallel swathing can be referred to as
‘absolute’ swathing. This is because each swath is an ‘absolute’ distance (swath number
multiplied times the swath width) from the A-B reference line.
To provide Contour Swathing guidance, the Smartbar memorizes each swath path as the
operator is driving. To simplify the progress through the field, each memorized swath is
separate from the other swaths. See the Contour Swathing Diagram below. Swath #1 starts
at the ‘1A’ mark and ends at the ‘1B’ mark. Swath #2 starts at the ‘2A’ mark and ends at the
‘2B’ mark, etc. The Smartbar memorizes the path of the two complete swaths. While driving
the first swath, the Smartbar memorizes the path of that swath. While driving the second
swath, the Smartbar shows relative guidance to the first swath while memorizing the second
swath. While driving the third swath, guidance to the second swath is shown while memoriz-
ing the third swath. This process is repeated across the field.
