DAVID BROWN 50D POWER
ENGINE DETAIL
The David Brown 50D tractor features a 6-cylinder diesel engine with a displacement of 248 ci (4.1 L), delivering 50 hp (37.3 kW) at a rated RPM of 1800, which offers a good balance of power for farming applications while maintaining fuel efficiency due to its 16:1 compression ratio. The liquid-cooled system, with coolant and oil capacities of 20 qts (18.9 L) and 11 qts (10.4 L) respectively, enhances thermal management, reducing the risk of overheating during prolonged operation. However, operators should monitor oil levels regularly, as maintenance may be more frequent with higher capacities and a compression ratio that may impose additional stress on engine components.
