TRANSMISSION 1
The International Harvester 574 tractor features a partially synchronized transmission with 8 forward gears and 4 reverse gears, allowing for smooth shifting between four synchronized low-range gears. The transmission's design provides an effective torque management system, making it suitable for a variety of agricultural tasks and enhancing operational efficiency. However, the partially synchronized nature may present challenges in more advanced shifting scenarios, particularly when transitioning between ranges under load, which could lead to wear or difficulty in gear engagements.
| Type | partially synchronized |
| Gears | 8 forward and 4 reverse |
| Description | Four synchronized gears (1-4) in low, high, and reverse ranges. |
TRANSMISSION 2
The International Harvester 574 hydrostatic tractor features an infinite forward and reverse gear system, providing smooth and responsive control, particularly beneficial for tasks requiring frequent directional changes. Its rarity in North America may limit parts availability and resale value, but it can be an advantage for European market enthusiasts seeking a specialized model. Ideal for applications in tight spaces, the hydrostatic transmission enhances maneuverability, making it advantageous for smaller farms and landscaping projects.
