Warning! To avoid unexpected move-
ment of the implement, disengage the
PTO after each use.
The PTO-driven equipment not requiring
high power take-off, must have 6-splined
coupling to run at 540 rpm. In this case it
is necessary to set 2037 rpm of the diesel
engine.
The PTO-driven equipment which re-
quires high power take-off operates at
1000 rpm of PTO shaft tail and is pro-
vided with 21-splined coupling to be at-
tached to PTO shaft tail.
