Your machine may be equipped with a high speed arrangement for changing the engine oil. The high speed arrangement allows the oil to be quickly withdrawn. The high speed arrangement allows the oil to be quickly replaced.The high speed arrangement has a hose which is attached to the oil pan at the drain hole. The other end of the hose has a quick coupler.Note: Drain the crankcase while the oil is warm. This allows waste particles that are suspended in the oil to drain. As the oil cools, the waste particles will settle to the bottom of the crankcase. The particles will not be removed by draining the oil and the particles will recirculate in the engine lubrication system with the new oil.Procedure for the Tractor
Park the machine on a level surface. Shut off the engine. Apply the parking brake.
