ENGINE DETAIL
The Case R tractor is powered by a 4-cylinder, Waukesha gasoline engine featuring a displacement of 132.7 cubic inches (2.2L) and a robust bore and stroke of 3.25x4.00 inches (83x102 mm), providing a good balance of torque and horsepower for various agricultural tasks. Operating at a rated RPM of 1425, it offers efficient fuel combustion but may face limitations in high-speed applications. With a coolant capacity of 17 quarts (16.1L), effective thermal management is ensured, making it suitable for extended operations, though attention to cooling system maintenance is critical to prevent overheating.

TRANSMISSIONS OVERVIEW
The Case R tractor features a 4-speed transmission, which allows for greater flexibility in varying field conditions compared to the 3-speed option. This advantage can enhance productivity by enabling more precise speed adjustments for tasks such as tilling or plowing. However, the complexity of the 4-speed system may lead to increased maintenance challenges and require more operator training for optimal performance.

4-speed 3-speed |
TRANSMISSION 1
The Case R tractor features a 4-speed forward and 1-speed reverse gearbox, allowing for versatile speed management during various agricultural tasks. The limited forward gears may pose a challenge in maximizing speed range for different field conditions, potentially requiring frequent gear shifts. However, this setup can enhance control in tight maneuvering situations, making it well-suited for smaller fields or precision applications.
| Gears |
4 forward and 1 reverse |
TRANSMISSION 2
The Case R tractor features a simple gear configuration with 3 forward speeds and 1 reverse, making it suitable for basic agricultural tasks and light towing operations. The limited number of gears may pose a challenge in maneuvering finely in variable terrain or heavy workloads, impacting efficiency during complex operations. For optimal use, this tractor is ideal for small fields and straightforward tasks where speed modulation is less crucial.

3 forward and 1 reverse |
MECHANICAL
The Case R tractor features a 4x2 2WD chassis which provides adequate traction for light agricultural tasks but may struggle on uneven terrain. The open operator station enhances visibility and comfort, making it ideal for short to moderate-duration operations in favorable weather conditions. Its 4-speed transmission allows for versatility in speed selection; however, the limited number of gears may restrict performance for complex tasks requiring finer speed adjustments.
