An adjusting device includes a lifting device for adjusting a position of an attachment in use and a locking mechanism. The lifting device is switched between a locking position and a free position under a locking action of the locking mechanism, the lifting device drives the attachment to move to a first position when the lifting device is in the locking position; and the lifting device drives the attachment to move to a second position so as to work when the lifting device is in the free position. The adjusting device has a simple structure, a low production cost, an easy maintenance, and a garden tool using the adjusting device can conveniently and quickly adjust the position of the attachment connected to the garden tool.

The present invention is a harvester header attachment designed to slice crop residue and till soil as a harvester is harvesting a field of crops. The present invention is a series of tillage devices attached to the bottom side of a harvester's header. As the harvester moves through a field of crops, the tillage devices spin on a bearing and cut into the crop's stalks, leaves, and root balls, tilling the standing crop residue. The present inventions will have down pressure from the weight of the harvester's header causing them to cut into the soil profile a couple of inches. This will allow the present invention to act as a tillage tool. With both the crop residue being punctured and the soil being tilled, the present invention will incorporate the soil with the crop residue and have many benefits for farmers' fields and equipment.

A soil treatment apparatus for loosening soil includes a supporting device and a holding device movably held on the supporting device. A plurality of injection elements are held on the holding device. The injection elements are insertable into and withdrawable from soil via a lifting device. A fluid supply device is in fluid connection with the injection elements for providing fluid. The supporting device includes a first supporting device portion and a second supporting device portion. The soil treatment apparatus is configured to be caused to move in a processing direction via the first supporting device portion. The holding device is held on the second supporting device portion. The first and second supporting device portions are arranged one behind the other in the processing direction and interconnected so as to be movable and in particular displaceable relative to one another in the processing direction.
