Our Clutch Head Bolts are specifically made to exactly match the original John Deere hardware found on Two-Cylinder tractors.  This Round Head Clutch Bolt  hardware matches the original round head clutch bolt designed for the Letter Series tractors.  These bolts are called Clutch Head Bolts due to the Clutch Head Drive design.  This special Clutch Head Drive system allows the John Deere Hood Bolts to be installed or removed without marking the bolts painted finish. Just like the original - only better!  We have designed our Clutch Head Bolts to out perform the originals!  A special plating on our clutch head bolts allows you to remove and reinstall them without concern about rust seizing them into place.  Left unpainted, the plating provides a shiny gold accent to your tractor's new paint.  Replaces John Deere A3232R, A4125R, H1085R.
