Replace Meter Drive Shear Pin
1.
A shear pin is used to protect meter drive from damage.
-
Excessive forces occur when meter cartridge is filled with product when fan is not running. Do not engage meters unless fan is running.
-
Excessive forces occur when certain seed sizes bind between meter rollers and meter housing. If binding occurs with small seed (less than 6 mm [1/4 in.]), the black meter roller, and small wear plate, switch to standard wear plate. If binding occurs with small seed (approaching 6 mm [1/4 in.]), the black meter roller, and standard wear plate, switch to green meter roller.
IMPORTANT:
Avoid transmission damage. Do not use any other hardware to replace factory specified shear pin (11M7017). See your John Deere dealer for correct repair parts.
