Maintenance
Change the Hydraulic System Filter
Service Interval: After the first 250 hours
Every 500 hours thereafter (Every 250 hours if using Mobil 1 15W50)
1.Stop engine, wait for all moving parts to stop, and allow engine to cool. Remove key and engage parking brake.
2.Locate the two filters under the transmissions. Remove filter guards.
3.Carefully clean area around filters. It is important that no dirt or contamination enter hydraulic system.
4.Unscrew filters to remove and allow oil to drain from drive system.
Important: Before reinstalling new filters, apply a thin coat of Exmark Premium Hydro oil on the surface of the filters rubber seal.
Turn the filters clockwise until rubber seal contacts the filter adapter then tighten the filter an additional 3/4 to 1 full turn.
5.Remove the vent plug on each transmission and fill through expansion reservoir, when oil comes out of vent reinstall plug.
Exmark Premium Hydro Oil is recommended. Refer to the chart for an acceptable alternative:

Exmark Premium Hydro | 500 Hours |
Oil (Preferred) |

Mobil 1 15W50 | 250 Hours |

6.Raise the rear of machine up and support with jack stands (or equivalent support) just high enough to allow drive wheels to turn freely.
7.Start engine and move throttle control ahead to 1/2 throttle position. Disengage parking brake.
A.With the bypass valve open and the engine running, slowly move the directional control in both forward and reverse (5 or 6 times).
B.With the bypass valve closed and the engine running, slowly move the directional control in both forward and reverse directions (5 to 6 times). Check the oil level, and add oil as required after stopping the engine.
C.It may be necessary to repeat steps A and B until all the air is completely purged from the system. When the transaxle operates at normal noise levels and moves smoothly forward and reverse at normal speeds, then the transaxle is considered purged.
Do Not change hydraulic system oil (except for what can be drained when changing filter), unless it is felt the oil has been contaminated or been extremely hot.
Changing oil unnecessarily could damage hydraulic system by introducing contaminates into the system.
