Changing the hydro oil on your John Deere Commercial Ztrak. Warning signs to look for.

In this video I go go over how to change the oil in the hydraulic pumps on the John Deere Commercial Ztrak mowers. This mower was a Z915B. The customer said the left hydro was loosing power while cutting. After doing a test run of the unit I confirmed the issue which side was having the issue. After seeing the condition of the oil and the amount of debris in the left side hydro's filter I figured a flush of the system and new oil and filters may solve the issue.
