Been doing some much needed maintenance on an J830 I recently aquired from a friend. Got the spark plug and air filter changed no problems. Downloaded the manual to see where the oil drain plug is at; no luck. Removed the blade and "housing". Thought I'd find the drain plug underneath. However, now I see 4 more bolts and no drain plug. Anyone know where the drain plug is on this thing? Those 4 bolts look like they're holding the engine to the frame of the mower.
If I remember right J830 us a walk behind mower. Your engine has no drain plug. Take out the dipstick and tip the unit on it's side to drain the oil into a pan.
