Description

PROBOSS replacement mechanical lumbar wing - Part number 11988411

Original replacement lumbar wing manufactured by PROBOSS, commercial part number 11988411, mechanical version. This internal backrest structural component is specifically engineered for PROBOSS tractor and agricultural machinery operator seats equipped with a mechanical lumbar adjustment system. Its primary function is to support and contour the lower-back padding, flexing in response to the adjustment knob to deliver customized, consistent ergonomic support. Constructed from flexible, high-strength technical material, it withstands repeated flexing cycles and continuous operator pressure without permanent deformation or fatigue. Replacing the lumbar wing is essential when the internal support becomes cracked, broken, or fatigued from extended field use, restoring full postural comfort to the backrest.
