I posted yesterday about my tiger cub not starting and i got a lot of advice that was very good. I got the mower running today and decided to change the Hydrolic and filter. I went to the scag dealer and they gave me 2 quarts of 20w50. I emptied the fluid, changed the filter and added the 2 quarts into the resivior. I fired the mower up and it doesnt move. I looked at the manual when i got home and saw that it said the hydo fluid should be 3 inches from the top. My question is #1 -does anyone know how much hydro fluid a tiger cub takes? #2 even if it is low on fluid shouldnt it work a little? The mower was moving fine before i decided to change the fluid. I am sure this is something simple. However, my shop is 30 min from my house and i know i am going to be thinking about this all night so if anyone has any ideas please let me know.
