Page 45 Front axle system - Powered front axle Rowtrac series axle lubrication - System components involved (continued) The main components of the Rowtrac axle lubrication system are: • Rowtrac Series 4WD Tractor Drive Axles have final drive upboxes at the ends of each axle. These upboxes do not have common passages with the axle center section so they require external plumbing to supply the required lubrication oil and then return it back to the axle center section.
