Our solid steel light switch knob is machined from solid steel bar stock just like the original and exactly matches the John Deere original profile. This replacement for John Deere Part F690R is no longer available from John Deere Parts.  The plastic replacements that are available and that come with the replacement switch look and feel horrible, not to mention that they won't hold paint. This Light Switch Knob is threaded to screw right onto the orignal shaft.

Fits all two-cylinder tractors:
L, LA, LI, A series, B series, R, G, D, 45 & 55 Combines and many others.
