Description

PROBOSS replacement backrest frame assembly - Part number 11988613

Original replacement backrest frame assembly manufactured by PROBOSS, commercial part number 11988613. This complete structural backbone is specifically engineered to form the main upright support frame on PROBOSS tractor and agricultural machinery operator seats. Its primary function is to support the backrest foam cushion, upholstery, and lumbar adjustment assembly while safely absorbing operator back loads during rough-terrain driving and intensive field maneuvers. Constructed from high-strength structural steel with a corrosion-resistant protective finish, it ensures exact geometric alignment with the seat base reclining pivots. Replacing the backrest frame is essential in the event of bending, cracked welds, or structural fatigue from heavy loads, restoring full rigidity, ergonomics, and operator safety.
