youtube - push mower oil change.... oil plug under mower deck
On a push mower you take the oil cap off our drain plug out (which ever it has) and tip the mower on its side with the carburetor up. Once the oil is drained, refill it. Riding lawn mowers have an oil drain bolt on the bottom of the engine and you change the oil and filter kind of like a car
That would depend entirely on the particular Toro mower you're referring to.
Every oil change 3000-5000 miles
One should first start the mower and let the oil get warm. Doing this will ensure that not much of the old oil is left in the tank. Next place an oil pan under the mower to catch the oil and then pull the plug pin. Let the oil drain out and then put the cap back in place. Refill the mower with new oil and the job is done!
Kawasaki 15 HP Ariens Lawn Mower takes 1.2 Litres of oil and maybe a little more when you change the oil filter
I don't think you need to. There is no motor, so it doesn't need oil.
Find a drain plug or turn it on it side and dump the oil out.
No, you are not supposed to change your spark plug wires during oil change service. Most car manufactures recommend an oil change every 3,000 miles. It is also recommended that you change your spark plugs every 2 years.
?? What filter? I gather it is a walk-behind mower. Just change the oil every 25 hours to keep it alive!
On the bottom of the mower, it takes 3/8" socket driver (no socket) to remove it
I recommend to change the oil every 25 hours or so. Oil changes are always a cheap insurance. I have had to rebuild or replace a few engines due to not changing the oil. When in doubt, change it.
