Re: To all the new tractor owners
Good advice to check it. Make sure you check the level cold, though - not hot; consult your owners manual for the process.
A couple of months ago there was a lot of discussion about things that didn't seem to be checked by the dealer before delivery and hydro fluid was on the list. My X394 came with the level above the "Add" line but below the "Full" line. I've been watching it to see if it drops a little bit with usage (posters said that it would), and it really hasn't moved. Coming up on 8 hours, I plan to change the oil and top off the hydro fluid at the same time.
The X300's with an accessible reservoir for the hydro fluid use the same thing - Low Viscosity Hy-Gard.
