ENGINE DETAIL
The New Holland 6635 is powered by the Iveco 8045.25 turbocharged diesel engine, providing 85hp at a rated RPM of 2500, which supports efficient towing and traction capabilities for medium-duty agricultural tasks. Key specifications include a displacement of 3.9L and a relatively low oil capacity of 12.4 quarts, suggesting routine oil changes might be more frequent compared to larger engines, enhancing maintenance but potentially limiting extended usage without servicing. The Thermostart pre-heating system will improve cold start performance, making this model advantageous for operators in colder climates.

TRANSMISSIONS OVERVIEW
The New Holland 6635 tractor features a 12-speed partially synchronized transmission with a synchronized shuttle, offering smooth directional changes without clutch disengagement, which enhances operator efficiency in field operations. Its optional 24-speed partial power shift provides finer control over gear selection, ideal for varying load conditions and terrain. This capability allows for improved fuel efficiency and productivity but may present a learning curve for operators unfamiliar with multi-speed systems.

TRANSMISSION 1
The New Holland 6635 features a Synchro Command transmission with 12 forward and reverse gears, providing versatility for various farming tasks. Its partially synchronized design allows for smooth gear transitions and efficient operation, particularly beneficial during field operations that require frequent stopping and reversing. An advantage is the left-hand reverser, facilitating quick directional changes, although synchronization may not be as seamless as fully synchronized systems under heavy load situations.

| Gears | 12 forward and reverse |
| Description | Four gears in three ranges with left-hand reverser. Gear and shuttle shifts are synchronized |
TRANSMISSION 2
The New Holland 6635's Dual Command transmission, featuring a partial power shift with 24 forward and 12 reverse gears, enhances versatility in various field conditions. Its four gears in three ranges with a two-speed power shift and left-hand reverser facilitate quick gear changes, ideal for tasks requiring constant shifting, such as plowing or hauling. However, the complexity of this system may pose a learning curve for operators unfamiliar with advanced transmission technology.
