ADVANCE-RUMELY 6A TIRES
The Rumely 6A tractor features a robust steel construction for both its agricultural front (30x6) and rear (48x12) wheels, which enhances durability and load-bearing capacity. However, the all-steel design may result in a harsher ride and reduced traction on softer soils compared to rubber tires. This tractor is particularly advantageous for heavy-duty applications in fieldwork and would perform well in hard, even terrain scenarios, but may struggle in muddy or loose conditions.
