PTO engaged or the parking brake off, the engine will
shut down.
Location
There are two different style seat switches used. The
ribbon type switch is located in the bottom of the seat
between the seat cushion and the seat base (Figure
247). The mushroom type is fastened to the bottom of
the seat base (Figure 248).
