Not sure what you have there, but it is not a part for a 10, 101, 226, 227, or 237 corn picker. Nor is it s part for a 10, 205, 210, 410, 234, 313, 334, 434, 335, 435, 612, or 812 corn attachment for a John Deere combine...
Parts Depot in Wiscosin has one of each. Calls N14032N a "blade" and N14033N a "knife". Don't know how that helps, but thats all I could find.
Thanks - I checked with Deere and they call them a front trash knife and a rear trash knife but have no idea what they fit. They do show a dealer with inventory - probably Parts Depot.
