Abstract: A device to facilitate the installation of a cultivator blade on a shank. The device comprises a frame having a configuration complementary to the peripheral configuration of the blade and defining a channel that fits over the cultivator blade to seat at least a portion of the edges or wings of the blade as well as to protect the tip of the blade. The device has a fortified or reinforced tip to provide a striking surface. To use, the blade is seated in the device and positioned on the shank and the installer can strike the striking surface and the force of the blow is spread along the periphery of the blade to prevent or reduce damage to any one area of the blade.
