ENGINE DETAIL
The Case 351 tractor is powered by a 4-cylinder gasoline engine with a 2.7L displacement, providing a moderate torque of 136 lb-ft at 1300 RPM, making it suitable for tasks requiring consistent low-end power. Its oil bath air cleaner ensures effective filtration in dusty conditions, although maintenance might be more frequent than a dry air filter. With a compression ratio of 7.25:1, it's optimized for reliable performance, though lower compression might limit high RPM efficiency; ideal for applications like light tillage or mowing rather than heavy-duty pulling.

J.I. CASE 351 ENGINE
The Case 351 tractor is powered by a J.I. Case 2.7L 4-cylinder gasoline engine, providing a balance between horsepower and fuel efficiency. Its 18.4-gallon (69.6L) fuel tank allows for extended operation in medium-duty agricultural tasks without frequent refueling. However, the gasoline engine may face challenges in fuel availability in rural areas where diesel is more common, potentially limiting its operational scope.

TRANSMISSIONS OVERVIEW
The Case 351 tractor features a 12-speed transmission paired with a 4-speed gear range, allowing for enhanced adaptability in various field conditions, improving operational efficiency. The wide range of gear options offers better torque management for tasks requiring precision, but may require skilled operators to effectively navigate the gear selection. This versatility makes it ideal for both high-speed transport and low-speed field work, positioning it as a robust solution for diverse agricultural applications.

TRANSMISSION 1
The Case 351 tractor features a Tripl-Range gear transmission with a total of 12 forward and 3 reverse gears, enhancing versatility for varying operational tasks. The four primary gears combined with three selectable ranges (low, direct, high) allow for optimal torque management and efficiency across different terrains and workloads, making it suitable for both agricultural and industrial applications. However, mastering the gear transitions may present a learning curve for operators unfamiliar with multi-range systems, necessitating training for efficient use.

TRANSMISSION 2
The Case 351 tractor features a simple gear transmission system with 4 forward and 1 reverse gear, providing ease of operation for basic tasks. The limited gearing may be advantageous for straightforward applications, such as small-scale farming or landscaping, where complex gear changes are unnecessary. However, the lack of additional speeds could challenge performance in varied terrains or specialized tasks requiring finer control over speed and torque.

MECHANICAL
The Case 351 tractor, with a 4x2 2WD chassis and manual steering, offers simplicity in operation but may limit traction in adverse conditions compared to a 4WD model. Its disc brake system ensures consistent braking performance, although the open operator station may expose the user to weather elements. The 12-speed gear transmission provides versatility for different tasks, making it suitable for flat terrain agricultural operations but less optimal for uneven fields where 4WD could be advantageous.

J.I. CASE 351 TIRES
The Case 351 tractor's tire specifications indicate a front tire size of 6.00-16, which offers a good balance of maneuverability in tight agricultural spaces, while the rear tire size options of 11.2-36 or 13.9-36 provide enhanced traction and stability for heavy loads. The smaller front tire may limit maximum ground clearance, which could pose challenges in uneven terrain scenarios. Overall, this configuration is well-suited for general farming tasks, but users should be cautious of potential understeering when operating on slopes or loose surfaces.

DIMENSIONS & TIRES
The Case 351 tractor has a compact wheelbase of 87.1 inches, which enhances maneuverability in tight spaces, making it ideal for smaller fields or landscaping applications. Weighing 3,840 lbs, it offers a balanced weight distribution that aids traction, especially with its larger rear tires (12.4-36) designed for improved soil penetration and stability during heavy-duty tasks. However, the relatively narrower front tires (6.00-16) may limit its lateral stability during steep terrain operations, potentially requiring careful operation on inclines or uneven ground.
