Rotation Definitions And Conventions
This instruction manual refers to relative rotational directions. The terms clockwise and anti-clockwise are
relative definitions and depend on the ope
rator’s viewpoint. To eliminate confusion the following definitions will
be used throughout this text;
Under normal cutting conditions flail rotation in the flail mower will be the reverse of the tractor drive wheel
rotation.
This will be defined as
’Reverse rotation’ (RR)
. See
Error! Reference source not found.
Figure 1.3(A).
[
Note
: for information only; When the direction of flail rotation in the flail mower is the same as the tractor drive
wheel rotation, this is defined
as ‘Forward rotation’ (FR)]
Figure 1.3
Additionally, other references to ‘clockwise’ and ‘anti-clockwise’ actions by the operator conform to international
right-h
and thread conventions for ‘screw down’ and ‘un-screw’ respectively.
This convention also extends to the definition of PTO drive rotation from the prime mover; see Figure 1.3(B).
