ENGINES OVERVIEW
The Massey-Harris 33 features a Continental 3.3L 4-cylinder engine available in both gasoline and diesel variants, offering flexibility based on fuel preference and operating conditions. Key advantages include robust torque delivery suitable for various agricultural applications, while the diesel model may provide improved fuel efficiency and longevity under heavy loads. However, consider that the gasoline engine may offer easier starting in cold conditions but at the cost of slightly lower torque output compared to the diesel engine.
