I Would like to change & flush the Hydro fluid on a 220 Grasshopper mower. What is the best and easy way to do this?

Although I've never done this on a mower, I have a good bit of fork lift hydraulic experience.
The most important thing to point out is that you should NEVER flush a hydraulic system in operation with a solvent! It will damage the pump and hydraulic motors. Using solvent on disassembled parts is okay.
Secondly, if the system filter has been changed occasionally and the fluid looks clean there is no need to change and flush unless the maintenance schedule calls for it. It is not like engine oil that must absorb combustion by products.
