Shear Protection

IMPORTANT: All shear protection pins should be replaced annually.

Replace the shear pin ONLY with shear pin of the same size. Do not replace with other type pins. Replacement cotter shear pins (A) are located on seed transmission or left-hand variable rate drive motor.

NOTE: If drill shaft binds due to misalignment, loosen bolts on drill shaft bearings on planting units. Make certain shaft turns freely, then tighten bolts.

Shear pins (A) may become deformed through normal usage. In this condition, it is possible for the shear pin to eventually fail without a machine malfunction.

Infrequent or improper lubrication causes "binding" of moving parts within the machine. This "binding" will cause the shear pins to shear, thus preventing breakage of machine parts.

Replacement cotter pins (B) and meter handle (C) are located on mechanical transmission or on left-hand variable rate drive motor.

If meter handle breaks; remove broken pieces, align flat surfaces (A) and insert new handle (B) through gearbox (C) until handle snaps into groove on shaft. Gearbox must seat into cutout (D).
