Max 25 HST FLUID

   / Max 25 HST FLUID #11  
It's HST, forward and backward pedal. This is why I'm confused. Thank you for helping by the way. I recently bought this and theres no fluid on the sightglass, I need to add or change it.
Well, now there's two of us that are confused. I don't even understand why they want GL-4 in the axle instead of GL-5.

Anyway, take a whiff of what's in there now. Gear oil smells nothing like hydraulic fluid.

I did add a couple more pictures, It does say the transmission is hydraulic+mechanical.

i just used the same fluid in the axle, it differs over the years based on the manuals

I used the same stuff in OP's pic. Never saw it in the sight glass and ended up overfilling it, I put in about 3 gallons of fluid. Do you know about how much extra these things hold? thanks

be careful, emax and max are 2 completely different machines, I can't speak to the emax.

FWIW, check your Hyd level before adding more. Mine was filled above the sight glass, and because Hyd fluid is relatively clear, it looked like it didn't have any fluid in the sight glass. If you don't have a dipstick on your reservoir, make your own with a long zip tie. Measure down from the fill port to the site glass, and then mark the zip tie accordingly. Will get you very close to the actual level of your fluid.
