Need help with Hydraulics!!!

Hey guys. I just put a new hydraulic filter on my Gravely promaster 100 series mower and now I need to know how to bleed the lines.

I have about 14 yards to mow tomorrow so any help would be appreciated!

The first thing if you didn't do it is to fill the new filter with hydraulic oil. Then start the mower and loosen the filter enough to let some oil seep out. Then tighten it for good. Lastly, Jack the wheels off the ground blocking it securely and so forth so it doesn't fall and let it run forever back and forth in reverse and forward. This is how I do it on my eXmarks. I guess it will work there as well. You may also check the user's manual for instructions on this.

Take care, Ed

Gravely's will purge as Ed explained, (Just a little clearer) Set the throttle about 3/4's and move the sticks forward and reverse slowly 8/10 times then test ride.
