A tissue button includes a body, a door, and a cross-pin that secures the door to the body. The door pivots relative to the body between an open position and a closed position. A first portion of a suture can be pulled when the door is in the open position, and a second portion of the suture cannot be pulled when the door is in the closed position. A cross-section of the cross-pin taken perpendicular to a longitudinal axis is non-circular.

In one embodiment, a tractor bucket attachment may include an attachment head and a loop of flexible cable. The attachment head may include a mounting bracket and first and second cable attachment mechanisms. The mounting bracket may be configured to secure the attachment head to a tractor bucket, the tractor bucket having a front edge. The loop of flexible cable may have a first end and a second end, the first end being attached to the first cable attachment mechanism and the second end being attached to the second cable attachment mechanism. The loop of flexible cable may be configured to ensnare a bale against the front edge of the tractor bucket.

In a cable connection structure in which a roughly spherical cable end disposed at the tip of an inner wire is connected to a movable member, the movable member is provided with a pair of wing pieces that hold the inner wire, a cable insertion opening that guides the cable end to a space between the wing pieces, and a roughly elliptical cable end passage part that displaceably supports the cable end. The long axis of the roughly elliptical shape of the cable end passage part roughly coincides with the direction of insertion of the cable.
