Cub cadet m50s (tank) problem with hydrostatic

[95dodgeram33]

Hey guys I have a 2006 cub cadet m50s zero turn mower that worked fine until I change the hydrostatic fluid now one side moves but the other doesn't I'm just wondering if there is a way to bleed it some way or something it has a new belt new filters. Thanks
