workmaster 55

[mannyrub]

I have a newholland work master 55 and I changed the front hydraulic arms the seal for the front end loader.when I shut it off to change a seal everything was running fine.once I changed the seals the tractor will not start.does the tractor have a low hydraulic fluid sensor that wont let it start. It is the only thing that I can think of.
