TRANSMISSION
The Yanmar Ex450 features a synchronized shuttle transmission, providing seamless gear transitions between its 9 forward and reverse speeds, ideal for tasks requiring precision in direction changes. The dual stage dry clutch enhances control while operating under load but may present challenges in smooth engagement compared to hydraulic clutches. Its oil capacity of 28 quarts (26.5 liters) ensures adequate lubrication for extended usage, although regular monitoring is essential to maintain optimal performance and prevent overheating.

YANMAR EX450 TIRES
The Yanmar Ex450 tractor's versatile tire options allow for adaptability across various applications, from agricultural to lawn care and industrial tasks. The 14.9-24 rear Ag tires provide excellent grip for field work, while the 44x16.1-22.5 turf tires enhance performance in landscaping scenarios, reducing soil compaction. However, the need to switch tire types for different tasks may require additional time and resources, and careful consideration of the intended use is crucial for maximizing efficiency and effectiveness.
| Ag front | 8-16 |
| Ag rear | 14.9-24 |
| Lawn/turf front | 27x12-15 |
| Lawn/turf rear | 44x16.1-22.5 |
