You can use Engen Agrifluid. It is even better than donax TD.
sity hydraulic fluids
small pieces have been from different parts of hydraulic system you can be infected hydraulic oil.
There are various forms of hydraulic fluids out there. Some are, some are not.
Not usually. Hydraulic systems use fluids. Pneumatic systems use gas.
Dexron III is itself an hydraulic fluid. The issue is, not all hydraulic fluids are equal in quality. General Motors recommends replacing the discontinued Dexron III with Dexron VI
PTO, hydraulics, or neitherThe first thing you need to know is whether the tractor has a PTO (Power Take-Off) or built-in hydraulics. Given the age of the tractor in question, likely it either has a PTO or neither. If it has hydraulics, you should be able to attach the splitter. This may require the purchase and installation of a hydraulic transfer box. Be wary if you look at doing this yourself...hyrdaulics are fluids under high pressure and can cause devastating injuries when they leak.If the tractor has a PTO, you can get PTO-powered hydraulic transfer boxes. From what I've seen they can be really expensive.If you have neither, you're likely not going to be able to get this working.
Mostly hydraulic fluids, maybe oil and coolant.
Pneumatic systems use air or an inert gas. Hydraulic systems use water or oil.
Wires stretch and sag. Hydraulic fluids transfer force with far smaller losses.
The pressure in a hydraulic system varies you need to be specific about the changes in volumes, temperatures and the hydraulic fluids involved.
Hydraulic
depends on what your putting the fluid in, in some cases, yes
