Hydraulic Drive Service
5.8 Regular external maintenance of the Hydraulic Transaxle drives will ensure proper cooling of the hydraulic
system. Maintenance should include the following:
5.8.1
Oil Level…
Inspect the oil level by locating the expansion tank behind the operator seat. The oil
level should be at the “Full Cold” line. If required, add oil until the oil level reaches the “Full Cold”
line. Never fill the expansion above the “Full Cold” line. The expansion tank’s primary purpose is
to allow heated oil to expand. If the tank is over filled, there is a potential during operation the oil
will expand enough to spill out of the cap.
5.8.2
Oil Recommendation…
Use a 20W-50 engine oil with an API classification of SL has been selected
by the manufacture and is recommended for normal operating temperatures.
Oil Volume: Approximately 2 quarts (each transaxle)
5.8.3 Fluid Change Recommendation… To ensure constant fluid quality levels and longer life; an initial
oil and filter change at 75 hours is recommended. Subsequent changes are recommended at
400 hr. intervals minimum.
Fluid Change Procedure (Boulevard Only)
5.8.4
Service Position…
Position the mower on a level surface, engage the park brake, and apply the
Bypass Actuator. Thoroughly clean the transaxles around the fill plugs and the oil filters before
removing.
5.8.5 Drain Oil… Place an oil drain pan (12 inch or more in diameter and 5 qt. capacity is optimal)
beneath the transaxles. Remove the oil filter guards and oil filters from each transaxle to drain oil.
