Operating the HSL with
GPS
Operating the HSL with the assistance of GPS can be
beneficial in several ways and is recommended.
The actual working width of the Landoll HSL is about 4"
less than the name plate value. Because of structural
symmetry, the 7833 HSL is off set to the right hand side
approximately four (4) inches. The right hand side of the
HSL will work one half of the name plate width, while the
left hand side will work approximately 4" less.

OPERATION AND MAINTENANCE
•
When operating the Landoll HSL with the assistance
of GPS guidance, set the swath width to the label
width in inches; less ten (10) inches.
•
For a more precise and efficient setting, set your
GPS guidance per the listings in the table.
•
When the GPS is set up to correctly to reflect the
distance worked either side of center, including the
offset, it becomes very easy to see if the HSL is
tracking straight by the distance overlapped.
•
When the GPS guidance is set correctly and the
Landoll HSL is tracking straight, there will be minimal
overlap on either side, and no skips.
•
GPS guidance also helps out when turning narrower
units on the headland. It becomes more efficient
when turning at higher speeds to not have to turn
back in, for what would be the next adjacent pass; but
instead work a rotation where one or two passes are
skipped to be completed later.
