A. Checking Hydraulic System Oil Level
The hydraulic system oil level should be checked after the first 10 hours of operation. Thereafter, check the oil after every 200 hours of machine operation or monthly, whichever occurs first.
If the oil level is consistently low, check for leaks and correct immediately.
1.Wipe dirt and contaminants from around the reservoir.
2.When the machine is "cold" (before operation), visually check the level of hydraulic system oil. Hydraulic system oil level should be in the middle of the indicator window located on the left side of the machine (See Figure
3.Clean the fill cap and install it onto the reservoir.
The hydraulic system oil should be changed if you notice the presence of water or a rancid odor to the hydraulic oil.
1.Park the mower on a level surface and stop the engine.
2.Remove the three 1/4” filter guard screws and filter guard from both axles. (See Figure
3.Place a suitable container under the hydraulic oil filters. Remove the cover from the left side tank to gain access to the hydraulic reservoir. Remove the fill cap from the reservoir.
4.Remove the hydraulic filters from both axles and allow the fluid to drain into the container. Properly discard the oil when the system has drained completely. (See Figure

B. Changing Hydraulic Oil
The hydraulic system oil should be changed after the first 120 hours of machine operation and every 400 hours or annually thereafter, whichever occurs first. The oil should also be changed if the color of the fluid has become black or milky. Ablack color and/or a rancid odor usually indicates possible overheating of the oil, and a milky color usually indicates water in the hydraulic oil.
