BIG BUD 400/20 POWER
ENGINE DETAIL
The Big Bud 400/20 tractor is powered by a robust Detroit Diesel 8V-92T engine, providing 400 hp and an impressive 19:1 compression ratio, making it suitable for heavy-duty applications like deep tillage or large-scale farming. Its significant displacement of 736 ci (12.1 L) ensures high torque for demanding tasks, while the turbocharging enhances performance at higher RPMs, ideal for fatigue in prolonged operations. However, maintenance can be a challenge due to the complexity of the turbocharged system and the need for regular servicing of its 24-volt electric starter system.
