Performing Daily
Maintenance
Before starting the machine each day, perform the
Each Use/Daily procedures listed in
(page 27).

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.

disconnected or damaged, the machine could
operate unexpectedly, causing personal
injury.
• Do not tamper with the interlock switches.
