ENGINES OVERVIEW
The Wallis Bear tractor features two engine options: a 17.4L and a more powerful 24.3L, both four-cylinder gasoline configurations, providing robust torque ideal for heavy-duty tasks. The higher displacement 24.3L engine may offer enhanced performance for demanding agricultural applications, but can lead to increased fuel consumption. When considering operational costs and farm equipment compatibility, the choice between these engines should reflect both the workload and efficiency preferences needed for optimal performance.

ENGINE DETAIL 1
The Wallis Bear tractor features a robust 4-cylinder, gasoline engine with a displacement of 1062 ci (17.4 L) and an impressive bore of 6.5 inches, highlighting its potential for high torque at low RPMs (650). The hand-crank starter, while historically significant, presents a challenge in safety and ease of use compared to modern electric starters. This tractor's specifications indicate suitability for heavy farm tasks in early 20th-century agriculture, but its operational complexity and lack of modern convenience may limit its appeal in contemporary settings.

ENGINE DETAIL 2
The Wallis Bear tractor features a 4-cylinder, 24.3 L liquid-cooled gasoline engine, known for its substantial displacement of 1480 ci, which provides robust torque for heavy-duty agricultural tasks. The 7.5-inch bore paired with a 9-inch stroke results in a favorable torque curve, although its hand-crank starter may pose challenges in modern usage, particularly in terms of ease of operation and safety. Ideal for collectors or vintage farming enthusiasts, this tractor represents historical engineering but may require specific maintenance due to its limited availability and unique parts.

WALLIS BEAR ENGINES
The Wallis Bear tractor features two engine options: a 17.4L and a more powerful 24.3L 4-cylinder gasoline engine, making it suitable for varying workloads. With a generous fuel tank capacity of 60 gallons (227.1 liters), it offers extended operational time, ideal for large-scale agricultural tasks or extended fieldwork. However, the gasoline engine may have higher operational costs due to fuel consumption compared to diesel alternatives, which could impact long-term economic viability.

TRANSMISSION
The Wallis Bear tractor features a basic 3-speed forward and 1-speed reverse gear configuration. This simplicity allows for easier operation and maintenance, particularly advantageous for small-scale farming or garden cultivation. However, the limited number of gears may restrict versatility and speed adjustments when facing diverse terrain or demanding tasks.

MECHANICAL
The Wallis Bear tractor features a 3x2 2WD chassis that is suitable for light to moderate agricultural tasks, providing good maneuverability in tight spaces. The mechanical power assist steering enhances operator control, which is beneficial in uneven terrain but may lack the precision of hydrostatic systems. The 3-speed gear transmission allows for flexibility in speed management but may limit performance in steep or heavy-duty applications; consider opting for the canopy for improved operator comfort in outdoor conditions.

DIMENSIONS & TIRES
The Wallis Bear tractor, with a weight of 16,000 lbs (7257 kg), provides enhanced stability and traction on uneven terrain, making it suitable for heavy-duty agricultural tasks. However, its substantial weight can pose challenges in terms of transportability and mobility on softer ground conditions. Operators should consider the specific soil type and field conditions to maximize efficiency and prevent soil compaction.
