ENGINE DETAIL
The Aultman & Taylor 15-30 tractor features a powerful 4-cylinder Climax gasoline engine with a substantial displacement of 510.5 ci (8.4 L), allowing for robust torque delivery, particularly beneficial for heavy fieldwork. With a bore/stroke ratio of 5.00x6.50 inches, it is optimized for low-end power, although it operates at a relatively low rated RPM of 900, which may limit top-end speed for transport but enhances durability for continuous operations. The 20-quart coolant capacity ensures effective thermal management, essential for maintaining performance during extended use in demanding agricultural scenarios.

AULTMAN & TAYLOR 15-30 ENGINE
The Aultman & Taylor 15-30 tractor is powered by a Climax 8.4L 4-cylinder gasoline engine, providing robust performance for agricultural tasks. Its total fuel capacity of 22 gallons (16 gal main + 6 gal auxiliary) allows for extended operation, minimizing downtime during fieldwork. However, the gasoline engine may offer less torque compared to diesel alternatives, potentially posing challenges when tackling heavier loads or demanding terrain.

TRANSMISSION
The Aultman & Taylor 15-30 tractor features a simple transmission with one forward and one reverse gear, which enhances ease of operation but limits its versatility in various field conditions. This design is advantageous for straightforward tasks, such as light plowing or towed applications, yet may struggle with terrain requiring speed control or varied power delivery. Operators should consider this tractor for small-scale farming or hobbyist use where minimal gear shifting is desired.
| Gears | 1 forward and reverse |
MECHANICAL
The Aultman & Taylor 15-30 tractor features a 4x2 2WD chassis, providing limited traction in challenging terrains compared to 4WD alternatives. Its 1-speed transmission simplifies operation but restricts versatility, making it ideal for flat, open fields but less effective in variable conditions. Users should consider its efficiency for specific agricultural tasks where speed variability is less critical.

AULTMAN & TAYLOR 15-30 TIRES
The Aultman & Taylor 15-30 tractor features a robust steel construction with 36x5 inch front wheels and 70x12 inch rear wheels, enhancing its stability and traction on uneven terrain. The larger rear wheels provide a significant advantage in plowing and tilling by distributing weight more effectively, reducing soil compaction. However, the all-steel composition may lead to increased weight, which can be a challenge for transportability and fuel efficiency compared to tractors with composite materials.

DIMENSIONS & TIRES
The Aultman & Taylor 15-30 tractor features a relatively short wheelbase of 98.5 inches, improving maneuverability in tight spaces but potentially limiting stability on uneven terrain. Weighing 8,240 lbs, it provides significant traction for field operations, though its weight may hinder transportability. The tire sizes, with a narrow front (36x5) and wide rear (70x12), enhance load distribution and facilitate plowing but may require careful tire pressure management to optimize performance on various soil types.
