ENGINE DETAIL
The David Brown 3800 features a gasoline 3-cylinder engine with a moderate displacement of 2.4L and low compression ratio of 6.75:1, which can enhance longevity but may limit power output compared to higher compression engines. Operating efficiently at a range of 700-2200 RPM with peak torque at 1400 RPM allows for effective low-end performance, making it suitable for tasks requiring consistent pulling force. However, the 12V starter system and oil bath air cleaner might necessitate regular maintenance to ensure optimal operation and engine longevity in varied conditions.
