MECHANICAL
The J.I. Case 2390 tractor features a 4x2 2WD chassis which may limit traction on steep or slippery terrains, making it less ideal for heavy tillage work in such conditions. The mechanical rear differential lock enhances traction when needed, while the hydraulic wet disc brakes provide reliable stopping power under load. The power steering and Silent Guardian cab with air conditioning ensure operator comfort, which is beneficial for prolonged usage, though the 12-speed partial power shift transmission may require a learning curve for efficient operation.
