How often should I change the oil in a Kohler KT745?

Change the oil in the Kohler KT745 every 100 hours of run time. Because it is measured in engine hours, log the hour-meter reading rather than a date.

What is the maintenance schedule for a Kohler KT745?

The Kohler KT745 is serviced on engine hours, not miles. Key intervals include Air Filter (every 25 hours), Engine Oil & Filter (every 100 hours), Fuel Filter (every 100 hours). Track the hour meter and service each item when its interval comes due.

Does the Kohler KT745 track maintenance by hours or miles?
