ENGINE DETAIL
The Avery 12-25 tractor features a 2-cylinder gasoline engine with a substantial displacement of 464.6 ci (7.6 L), providing robust torque for heavy-duty applications. Its liquid-cooling system ensures efficient thermal management, prolonging engine life, while the bore/stroke ratio (6.50x7.00 inches) promotes low-end power delivery. Operating at a low rated RPM of 700 may limit peak speed, but it enhances durability and is ideal for tasks requiring consistent power, such as plowing or hauling.

AVERY 12-25 ENGINE
The Avery 12-25 tractor features a robust 7.6L, 2-cylinder gasoline engine, delivering reliable power for agricultural tasks. Its 14-gallon (53.0 L) fuel tank provides extended operational time, beneficial for large fields; however, gasoline engines generally have lower fuel efficiency compared to diesel counterparts. Consider this tractor for tasks requiring moderate power in short-duration, high-intensity scenarios, but be cautious of fuel costs during extensive use.

TRANSMISSION
The Avery 12-25 tractor features a simple gear type transmission with only 2 forward and 1 reverse gear, making it less suited for complex tasks that require variable speed control. This limitation can hinder efficiency in operations such as plowing or cultivating, where varying speed is essential for optimal performance. However, its straightforward design offers ease of maintenance and reliability for users who perform basic farming tasks in less demanding environments.

| Gears | 2 forward and 1 reverse |
MECHANICAL
The Avery 12-25 tractor features a 4x2 two-wheel drive chassis, which offers simpler handling and lower maintenance compared to four-wheel drive systems, but may struggle on uneven or muddy terrain. Its 2-speed gear transmission allows for basic speed adjustments, enhancing versatility in light agricultural tasks. However, the limited gearing options may reduce performance efficiency in more demanding applications, making it ideal for smaller scale operations or lightweight tasks.

AVERY 12-25 TIRES
The Avery 12-25 tractor features agricultural front tires sized 30x8 and rear tires sized 56x20, both constructed from steel, which enhances durability and load-bearing capacity. The larger rear tires provide improved stability and traction in field operations, making it suitable for heavy tillage tasks. However, the steel construction may lead to increased weight, potentially impacting maneuverability on softer terrains.

DIMENSIONS & TIRES
The Avery 12-25 tractor weighs 7500 lbs (3402 kg), providing stability while operating in various terrains. Its larger rear tires (56x20) facilitate enhanced traction and load distribution, making it suitable for heavier tillage and hauling tasks. However, the smaller front tires (30x8) may limit steering precision in tight spaces, making it less adept on undulating terrain compared to tractors with more uniform tire sizes.
