MECHANICAL
The Minneapolis-Moline 5 Star tractor features a 4x2 2WD chassis, suitable for flat terrain with limited traction capabilities compared to 4WD models. The disc brakes provide reliable stopping power, while the power-assisted steering enhances maneuverability, especially in tight spaces. The 10-speed partial power shift transmission allows for versatile speed adjustments, making it ideal for varied farming applications, though operators in hilly areas may find the 2WD configuration a challenge on inclines.
