    I just bought i used commerical gravley 34z and was wondering what I need to do on a regular basis so this machine will last me. The mower has 400 hours on it. I know I need to change the oil and stuff like that but what else? How do I know when to change the hydro oil? Any help will be greatly appreciated!!!

    Check the Gravely web site and you can find the owners manual. You will need the model and serial number of your mower for the correct manual.
