Question:
I have a RZ5425 Zero Turn Mower a little over 2 years old. After ~20-30 minutes operation, the right hydraulic drive become noisy and sluggish in response. The noise is rough, but short of grinding, with intermittent clicking. Not to the level of cavitation that I am familiar with, but possibly the case. I was thinking it is probably related to the fluid heating up and viscosity degradation.
I am looking for guidance on checking/changing the hydraulic fluid on the RZ5424, as I do not see anything in the manual or learn anything from the Parts Diagram. Specifically, I do not see a hydraulic reservoir, so it may be sealed, but hopefully still maintainable. Specification of recommended fluid is of interest as well.
Thanks
