I
OPERATING THE TRACTOR
■^NOTE
This unit is equipped with a
safety
interlock
system
for
your
pro¬
tection. The purpose of the safety
interlock system is to prevent the
engine from cranking or starting
unless the brake/speed control pedal is
depressed and the PTO lever is
in the disengaged position. In addi¬
tion, the PTO lever must be in the
disengaged position when the unit
is put into reverse or the engine
will shut off. If the operator leaves
the seat with the PTO lever engaged, the
engine will shut off.
