A suspension system for cold planer with four tracks is disclosed. The suspension system includes a hydraulic cylinder for each track, an additional bypass valve for each hydraulic cylinder and an additional bypass valve that bypasses the operation of the front control valves that control the elevation of the front tracks during a cutting operation. During transport or roading of the cold planer, the bypass valves are energized by a controller and the energized bypass valves provide communication between the head ends of the left side cylinders and the head ends of the right side cylinders. During roading, the energized bypass valves also provide communication between the rod ends of the front cylinders and between the rod ends of the rear cylinders.
