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.
Operating the Parking

Always set the parking brake when you stop the
