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.
