ENGINES OVERVIEW
The Eagle Manufacturing 6A tractor is equipped with a powerful Hercules 5.6L or Waukesha 5.9L six-cylinder gasoline engine, providing robust performance in various agricultural tasks. Its engine displacement aids in high torque delivery, ideal for heavy-duty applications; however, operators should consider fuel economy implications with high-capacity gasoline engines. For optimal efficiency, coupling with proper transmission systems can enhance power-to-weight ratios, making it well-suited for both fieldwork and transport scenarios.

MECHANICAL
The Eagle Manufacturing 6A tractor features a 4x2 2WD chassis, offering a basic drive system suitable for lighter agricultural tasks but limiting traction in rough or muddy conditions. The manual steering system can be less responsive than power steering, leading to increased operator fatigue during extended use. With a 3-speed transmission, it provides limited speed versatility, making it efficient for specific tasks but potentially unsuitable for varied terrains and demanding applications.
