Can you safely dye hydraulic fluid

[Buggs67]

I bought some of the JD dye the other day. The dealer kept asking me what it was when I ordered it.

Sure makes seeing the fluid in the hydrostat sight glass MUCH easier. I dribbled a little into a jug of fluid and it was bright red afterwards. This stuff should go a long way. I plan to use a pipette to put a very small amount into a jug and see how much I need.

Old post, but I have the same problem.
I called JD dealer. He looked up the part # and it's $4 and change. He doesn't stock it, never heard of it, didn't know what it's for. I explained and he said JD fluid isn't clear and couldn't understand why they make it. He's happy to order it for me and I'd rather give him the business than the interweb. Plus it'd give me a chance to look at the "toys" and maybe buy something I don't know I need yet :tractor:

Wow... $12.95 for something JD sells for $4.27.

I added some to my 2720 when I changed the hydro oil. Along with making it easier to see the level in the sight glass, it makes it much easier to see any small leaks, especially during the winter in the snow.

It's always nice to be able to immediately distinguish between hydro oil, engine oil and coolant.

Not surprised. $8-9 is a pretty typical shipping and handling charge for small items.
