Back and Forth Swathing (BF)
Back and Forth swathing is used, as the name applies, to swath the field in first one direction
and then the other using swaths that are parallel to the A-B line. Below are the steps required
for BF swathing.
The straight line defined by marks A and B must be parallel to the remaining swaths. Make
sure the GPS antenna has a good view of the sky and the Smartbar shows NO alarm condi-
tions.
If DIR is set to Automatic (AUT), the Direction is set automatically when the machine turns
past 75
o
alignment to the A-B line. If DIR is set to Manual (MAN), press the SELECT button
(after marking B and turning) to set the direction.
The SELECT button and DOWN button are then used to choose the next swath you want to
run. Swaths are numbered in order but you can run any swath you want at any time and in any
direction.
Important
The ‘A’ and ‘B’ marks form a straight line that must be parallel to the remaining
swath paths. Ensure that no alarms are present while setting the ‘A’ and ‘B’ marks.
Snap-to-Swath Swathing (SNP)
When using SNP, the Smartbar will find the swath nearest to the current position and set the
swath number accordingly. Swath lines are numbered as in BF swath type. The SELECT/UP
button and DOWN button do not control the swath number as in Back and Forth Swathing.
With the SNP pattern, you can work the field with the least need for pressing Smartbar but-
tons.
First, mark the A-B line as you would with BF, and then make your turn. If (DIR) is set to Auto-
matic (AUT), the Direction is set automatically when the machine turns past 75
o
alignment to
the A-B line. The following section leads you through a step-by-step description of swathing
using either BF or SNP swath patterns.
