Mechanism for mounting a soil leveling device

摘要

A mechanism for mounting a soil leveling device to the mounting arm of a leveling attachment operates in either a fixed setting or a floating setting. The mechanism includes a rearwardly extending carrier arm which carries the soil leveling device at its distal end. The carrier arm is pivotably connected at its proximal end to the mounting arm of the leveling attachment for upward and downward movement. A connecting link is mounted to the mounting arm and a spring assembly extends between the link and the carrier arm. The connecting link is selectively operable in either a fixed setting or a released, floating setting. When the connecting link is in the fixed setting, the spring assembly biases the carrier arm and the leveling device with a downward force. When the connecting link is in the floating setting, the leveling device can move across a soil surface free of a downward bias from the spring assembly.
