ABSTRACT:
The present invention contemplates a shield arrangement for the power take-off shaft of a tractor or like piece of equipment. The arrangement includes an inverted, U-shaped shield member which is pivotally mounted to the tractor for movement between raised and lowered positions, wherein in the lowered position the power take-off shaft is shielded. The arrangement further includes a spring-loaded, strut-like link pivotally mounted within the shield member. The link member is adapted to contact the power take-off shaft for supporting the shield member in its raised position, with the link member configured to disengage the take-off shaft upon initiation of the shaft's rotation for automatically lowering the shield member.
