A stripper band for a crop pick-up includes a U-shaped plastic body having an upper leg and upper bight portion reinforced by a sheet metal strap so as to stiffen the band for being able to withstand downward forces applied by heavy windrows of crop being picked up and conveyed over a top surface of the band. The sheet metal strap has upstanding bosses located about upper rear mounting holes against which clamping forces are directed when securing the band to the pick-up frame. Front and lower regions of the band are constructed only of plastic and remain flexible enough to absorb impacts from hard objects without permanent deformation of the band.
