#2 How often do I need to change the engine oil? I bought it in May and the engine oil comes with that. After that, I have been continuously using it.
You should change the oil after the first 5 hours of use. It should then be changed every 50 hours or annually.
#3 If this mower has no oil drain plug, how do you drain the oil in order to change it?
If you do not have an oil drain plug, you will need to tip the mower on its side, opposite of the air filter, and drain the oil from the oil fill tube.
The oil drain opening is under the mower. You need to tip the mower on its side the plug is right under the oil measuring stick. Make sure you have a oil pan right under the oil plug.
#7 What is the process for changing from side discharge to mulching, and is it easy to do?
All you need to do is remove the side discharge chute and the mulch cover will come down to cover the hole in the side of the deck. That is all you need to do to start mulching.
