The invention pertains to a torque limiter (100) for limiting the torque applied to row units of an agricultural harvesting head. The limiter comprises a base (102) configured to communicate a drive torque to a row unit and having first external threads (164) extending about the periphery of the base (102); an output plate (106) coupled to the base (102); an input plate (104) drivingly coupled to the output plate (106), the input plate (104) being configured to receive the drive torque from a row unit drive shaft (114); a spring (110) disposed to press the input plate (104) against the output plate (106); and a shell (112) surrounding the spring (110) and having an aperture (116) at a first end of the shell (112) to receive the row unit drive shaft (114) and having second threads (162) engaging the first threads (164). |
