Question: which is better 2 stroke or 4 stroke grass cutter?
Answer: With 4-cycle trimmers, the engine produces one power stroke every 4 cycles. This means that given the same engine size and gas, a 2-stroke engine will produce more power than a 4-stroke engine. Still, 4-cycle engines have their advantages. ... During cycle 4, the exhaust valve opens to allow exhaust gases to escape.
