ENGINE DETAIL
The Case 2594 tractor features a robust turbocharged 6-cylinder diesel engine with a displacement of 8.3L, delivering 217hp at a rated RPM of 2100, making it suitable for heavy-duty agricultural tasks. The large oil capacity of 30 quarts and coolant capacity of 44 quarts ensure effective engine protection and thermal regulation, vital for prolonged operation in demanding conditions. However, its sizable displacement means higher fuel consumption, which could be a consideration for long-duration projects or cost-sensitive operations.

J.I. CASE 2594 ENGINE
The Case 2594 tractor is powered by an 8.3L 6-cylinder diesel engine, known for its robust performance and fuel efficiency. Key advantages include high torque delivery at low RPMs, which enhances productivity during heavy field operations. However, ensure proper maintenance of the fuel system to mitigate potential issues with injector wear over time, especially in high-load scenarios.

TRANSMISSIONS OVERVIEW
The Case 2594 tractor features a 12-speed and a 24-speed transmission with power shift capabilities, enhancing operational efficiency and performance in varied agricultural tasks. The three-speed power shift allows for smooth transitions between gears under load, while the four-speed version offers more torque management options, beneficial for heavy-duty applications. However, the complexity of these transmission systems may require more maintenance and operator training to maximize their advantages.

TRANSMISSION 1
The Case 2594 tractor features a three-speed power shift transmission with a total of 12 forward and 3 reverse gears, providing flexibility for various field conditions. With an oil capacity of 128 quarts (121.1 liters), it ensures adequate lubrication for extended operation, though regular monitoring is crucial to avoid overheating. A key consideration is that reverse operation is unavailable in the fourth range, which could limit maneuverability in tight spaces or during certain tasks, necessitating careful gear selection.
| Type | three-speed power shift |
| Gears | 12 forward and 3 reverse |
| Oil capacity | 128qts / 121.1L |
| Description | Three power-shift gears (1-3), plus reverse, in four ranges (1-4). Reverse does not function in fourth range |

| Description | With 20.8x38 rear tires |
TRANSMISSION 2
The Case 2594 tractor features a four-speed power shift transmission that provides 24 forward and 3 reverse gears, offering a versatile range for various field applications. The 128-quart (121.1L) oil capacity ensures optimal lubrication and cooling for extended operational efficiency but may require careful monitoring to prevent overheating. Note that reverse operation is restricted in the fourth range, which may limit maneuverability in certain situations; therefore, plan gear selection accordingly for specific tasks.
| Type | four-speed power shift |
| Gears | 24 forward and 3 reverse |
| Oil capacity | 128qts / 121.1L |
| Description | Six power shift gears (1-6), plus reverse, in four ranges (1-4). Reverse does not work in fourth range |

MECHANICAL
The Case 2594 tractor features a 4x2 2WD chassis, making it suitable for lighter tasks rather than heavy-duty applications where 4WD would be beneficial. Its power steering enhances maneuverability, and wet disc brakes provide reliable stopping power under various conditions, reducing maintenance needs. With a choice of a 12-speed or 24-speed power shift transmission, operators have the flexibility for precise control and efficiency during fieldwork.

J.I. CASE 2594 TIRES
The Case 2594 tractor features a versatile tire selection, with options for both front (14Lx16) and rear (ranging from 24.5x32 to 20.8x42) that cater to various agricultural applications. The larger rear tire options enhance traction and stability on uneven terrain, making it suitable for heavy-duty tasks such as plowing or hauling. However, operators should consider compatibility with soil conditions and weight distribution, as larger tires may impact maneuverability in tighter fields.
