Cub Cadet 754-05129 V-Belt B-Section

This B-section classical V-belt serves as the upper PTO to cutter deck drive belt on select Cub Cadet Pro Z 700 and Pro Z 900 series zero-turn mowers. It transmits power from the engine PTO clutch to the mower deck spindle assembly. The belt features aramid fiber (Kevlar) tensile cords embedded in a rubber compound body, providing high tensile strength, minimal stretch, and resistance to shock loads encountered in commercial mowing applications. The wrapped fabric cover ensures smooth engagement and wear resistance against idler pulleys. It replaces OEM part numbers 754-05129 and 954-05129. Direct fit for 72-inch cutter deck configurations on listed Pro Z models.
