Abstract
An oil drain valve and oil sight gauge assembly for an internal combustion engine of an implement such as a lawnmower. The oil drain valve includes a valve member disposed in a valve body attached to the engine housing and disposed above the mower deck. The valve member may be selectively moved to allow oil to drain from an oil sump in the engine crankcase through a drain opening disposed below the mower deck. The valve member is retained in the valve body when the oil drain valve is opened to prevent the valve member from being lost. The oil sight gauge is internally vented to the crankcase to provide an accurate indication of the oil level in the crankcase, and is visually associated with the oil drain valve to provide an operator with a visual confirmation that all of the oil has been drained from the crankcase.
