Backhoe help, added tractor hydraulic oil to my JD 410 backhoe

[acadie1]

Topping up the trans/hyd fluid in my 1978 JD 410 today when I realized that I was adding the hydraulic fluid for my Case farm tractor. I probably put less than two litres in before I realized what I was doing. How fatal is this? I really do not like to contemplate changing the fluid in the JD as the manual indicates that it holds about 20 US gallons.
Thanks,

2 liters in a 20 US gallons, I would not worry about it. By the way, :welcome: to TBN!
