PTO "Disengaged"
When the PTO lever is set at the "Disengaged"
position, the clutch lever (2) connected to the PTO lever
via a link mechanism rotates to the front side of the
machine.
Spring (8) tension pushes the spline boss (3) toward
the front side of the machine, which creates clearance
between the clutch disc and friction plate (4), causing no
friction.
This eliminates the clearance between brake discs
and friction plate (9), causing friction.
Driving power to the PTO shaft (1) is thus shut off
and brake engages to prevent the PTO shaft (1) from
free-spinning.
