TRANSMISSIONS OVERVIEW
The CaseIH 685XL features an 8-speed synchromesh transmission which provides smoother gear changes, ideal for general farming tasks, and a 16-speed two-speed power shift option that enhances versatility for varied work conditions. The power shift allows for quick shifting under load, improving efficiency for tasks requiring frequent speed adjustments. However, operators must be familiar with the operational intricacies of each transmission type to optimize performance in heavy-duty scenarios.

TRANSMISSION 1
The CaseIH 685XL tractor features a synchromesh transmission with 8 forward and 4 reverse gears, providing smooth shifting and versatility for various tasks. The 304mm dry disc clutch ensures effective power transmission and durability under load, but may require careful maintenance to prevent slippage. This setup is advantageous for operations needing frequent directional changes, such as loading or field work, promoting efficiency in tight spaces.

| Gears | 8 forward and 4 reverse |
| Clutch | 304mm dry disc |
| Description | Four synchronized gears in two ranges, plus reverse range |
TRANSMISSION 2
The CaseIH 685XL tractor features a two-speed power shift transmission with a total of 16 forward and 8 reverse gears, enabling versatile speed selection for various tasks. The integrated torque amplifier allows for on-the-move shifting, enhancing productivity during heavy load operations, though it may require careful handling to avoid excessive wear. The dry disc clutch (304mm) offers robust engagement but may present challenges in maintenance compared to wet systems.

| Gears | 16 forward and 8 reverse |
| Clutch | 304mm dry disc |
| Description | Four synchronized gears (1-4) in two ranges (low/high) plus reverse range. Two-speed torque amplifier provides an on-the-move shift to a lower speed |
MECHANICAL
The CaseIH 685XL's chassis offers versatile 2WD and 4WD configurations, enhancing traction and stability depending on field conditions. With hydrostatic power steering, maneuverability is improved, while the wet disc brakes provide effective stopping power and reduced wear in demanding tasks. The 8-speed synchromesh and optional 16-speed two-speed power shift transmission allow for efficient speed management, making it suitable for both heavy-duty agricultural operations and lighter field tasks.

CASEIH 685XL TIRES
The CaseIH 685XL tractor offers both 2WD and 4WD configurations, providing flexibility for diverse agricultural applications. The 2WD model with larger rear tires (16.9-34) enhances traction during tillage, while the 4WD variant improves stability and reduces soil compaction, making it ideal for heavier loads and varied terrain. However, the initial purchase cost and maintenance complexity are higher for 4WD systems; the choice depends on operational needs and field conditions.
