Breaking in a New Machine
New engines take time to develop full power. Mower
decks and drive systems have higher friction when
new, placing additional load on the engine. Allow
40 to 50 hours of break-in time for new machines to
develop full power and best performance.
Using the Rollover
Protection System (ROPS)
WARNING
To avoid injury or death from rollover: keep
the roll bar in the raised locked position and
use the seat belt.
Ensure that the rear part of the seat is secured
with the seat latch.

Check carefully for overhead clearances
(i.e., branches, doorways, electrical wires)
before driving under any objects and do
not contact them.
