Change Hydraulic fluid

[turbomoparboy]

I have a 94 763. What is the best way to change the hydraulic fluid? Where is the drain? I dont know when mine was changed last and what is in there. The filter was changed last about 10 years and 600 hours ago ( the machine sat for years) I was thinking about draining it, changing the filter above the engine, refill, run it for a little while then drain it again as well as change all the filters. Anyone ever use Shell Donax 10w30 tractor transmission hydraulic fluid? Thanks, Justin

Does anyone know how to drain some or all of the hydraulic fluid?

The way i do it is to run my machine at idle and pump the oil out of the aux lines. As soon as it starts to spit, shut it down. Change the filter and re-fill with fluid.
If the system was contaminated, keep the old filter on, put in a few litres of oil (say a 5 litre bottle), drive it around lift/tilt. Run at idle and pump more fluid out, repeat till the oil is a good colour. Replace the filter and fill with fluid.
