Safety
Rollover Protection System
(ROPS) Safety
•The ROPS is an integral safety device. Do not
remove any of the ROPS components from the
machine.
•Ensure that the seat belt is attached and that you
can release it quickly in an emergency.
•Keep the roll bar in the fully raised and locked
position and always wear your seat belt whenever
the roll bar is up.
•Check carefully for overhead objects before you
drive under them, and do not contact them.
•Replace damaged ROPS components. Do not
repair or alter them.
•There is no rollover protection when the roll bar
is down.
•Wheels dropping over edges, over steep banks, or
into water can cause a rollover, which may result
in serious injury or death.
•Do not wear the seat belt when the roll bar is down.
•Lower the roll bar only when absolutely necessary;
raise it as soon as clearance permits.
•In the event of a rollover, take the machine to an
Authorized Service Dealer to inspect the ROPS.
•Use only Toro approved accessories and
attachments for the ROPS.
Safety and Instructional
Decals
Safety decals and instructions are
easily visible to the operator and are
