MECHANICAL
The Advance-Rumely OilPull W 20/30 features a 4x2 2WD chassis, ideal for flat terrain but limiting traction in adverse conditions. Its open operator station enhances visibility and ventilation but may expose the driver to weather elements. With a 3-speed gear transmission, operators can efficiently manage speed for various field tasks, but the lack of advanced options may hinder performance in more demanding applications.
