4.06 - Driveline
DANGER: Only use the original driveline supplied with this mower and always
with the safety shielding. Carefully read and file away the driveline operator’s
manual supplied by the manufacturer. The following does not substitute the
information found in the driveline manual.
IMPORTANT: Always check driveline length during initial setup and when connecting to
a different tractor.
In the collapsed position the driveline should be approximately 2” from bottoming out to
prevent possible damage to the tractor or implement. When the driveline is in the
maximum extended position, the ideal minimum overlap of the two halves should be
approximately 6” (see fig. 16).
