MECHANICAL
The J.I. Case 1390 tractor features a versatile 4x2 2WD/4x4 MFWD drivetrain, which provides adaptability for different terrains, but may struggle in particularly muddy conditions compared to dedicated 4WD models. The hydrostatic power steering offers improved maneuverability, while the mechanical drum brakes may require more maintenance than modern hydraulic systems, impacting long-term reliability. With a 12-speed synchromesh transmission, operators benefit from smooth shifting in various speed ranges, enhancing operational efficiency for a range of agricultural tasks.
