Technical Specifications and Performance: Deciphering the Data
The Case 446's heart is its Onan B43M engine, delivering a robust 12-14 horsepower—a variation commonly seen due to manufacturing tolerances and reporting differences. This discrepancy doesn't diminish the tractor's powerful performance. Its hydraulic drive system, while renowned for its strength, presents its own maintenance considerations.
| Feature | Specifications | Notes |
|---|---|---|
| Engine | Onan B43M | Robust and reliable engine, though parts availability may be a consideration. |
| Horsepower | 12-14 hp | Variation reflects manufacturing tolerances and reporting discrepancies. |
| Fuel Capacity | ~3 gallons (11.4 liters) | Slight variations reported across sources. |
| Hydraulic Fluid | ~1.2 gallons (4.7-6.1 liters) | Volume may vary slightly depending on model and reporting. |
| Approximate Weight | 770-800+ lbs | Weight can fluctuate depending on added accessories and equipment. |
This table reflects typical values – variations should be expected in vintage equipment. The tractor's versatility is further enhanced by a range of attachments, including mower decks and snow blowers, extending its functionality throughout the year. Isn't the ability to tackle different tasks a key factor in a garden tractor's appeal?
