Are lawn mowers two cycle engines?

Two-cycle engines are able to propel your lawn mower, snow blower or pressure washer in one crankshaft revolution and two strokes of the piston. The vast majority of the small engines Briggs & Stratton manufactures are 4-cycle engines, which require four strokes of the piston to complete a crankshaft revolution.

Do you use 4-cycle or 2 cycle oil for lawn mower?

What type of engine is a lawn mower?

Most lawn mowers are powered by four-cylinder engines, but some walk-behind lawn mowers use two-cylinder engines. Four-cylinder engines are typically more efficient and eco-friendly, compared to two-cylinder engines.
