    The hydraulic unlock system field conversion kit is available for FM20 and FM21 Series Flex-Wing Grooming Mowers.

     

    This conversion kit allows the operator to unlock the wings from the tractor seat with the convenience of a hydraulic lever. It replaces the standard rope disengagement that comes with the flex-wing mower.

     

    The hydraulic unlock system requires one additional selective control valve (SCV) (two total) and is ideal for lawn services that fold and unfold the unit to go from job to job.
