When to change the motor oil?

Once purchased Bad Boy Mower will come with Shell 10w 30 motor oil and diesel mowers come with Shell 15W40 motor oil already in the engine. This motor oil will need to be exchanged during the first 50 hours of usage and then every 100 hours from that time on. Proper motor oil can easily be purchased at the local dealer or service station.
In order to exchange the motor oil you should
1. Locate the motor oil valve
2. Drain the mower by opening the valve and drain the oil
3. Close the valve
4. Re-fill the engine with the proper amount of new motor oil designed for your mower
5. Recycle the old oil properly
