INTERLOCK SAFETY SYSTEM
The interlock safety system is to prevent the en-
gine form starting if the blade switch is engaged or
the neutral lock bails is unlocked. It also causes
engine shutdown if the operator falls from, or at-
tempts to leave the operator position while the
blades are engaged or the neutral lock bail is un-
locked. After the engine starts, the operator must
hold either the left or right O.P. lever down before
engaging the blades or unlocking the neutral lock
bail. If neither O.P. lever is held the engine will stop.
Check the function of the safety electrical system
on a regular basis.

turnbuckle until the tire stops turning. Holding
down the O.P. lever, release the neutral lock bail
from the drive levers. This will cause the tires to
rotate in full forward. Squeeze the drive levers

nut. Repeat on other side if necessary.
