A lock-up mount apparatus for an earth working tillage tool includes a bracket which is provided for attachment to a toolbar and the bracket has a first, second, third and fourth pin opening therein. A tillage tool, such as a cultivating tine, has an attachment structure at the top thereof and this attachment structure has a first and second hole disposed therethrough. A first pin is provided for selectively extending through the first pin opening in the bracket and through the first hole in the attachment structure whereby the attachment and thereby the tillage tool is pivotally attached to the bracket. A second pin is provided for selectively extending through one of the second and third pin openings in the bracket. The second pin also extends through a second hole in the attachment structure when the second pin is disposed in the second pin opening in the bracket whereby the tillage tool is held in a low operative earth working position. The tillage tool is held up in an intermediate non-earth working position when the second pin is disposed in the third opening in the bracket. When the first pin is disposed through the fourth pin opening in the bracket and through the first hole in the attachment structure, and the second pin extends through the first opening in the bracket, the tine is held in a high non-working storage position.
