Abstract: An agricultural working device, such as a mulcher, is improved with a working rotor which is driven by a drive shaft and a cutting rail with a cutting edge which can be directed towards the working rotor. Sensors for acquiring parameters of working rotor and/or cutting rail are provided. An electronic control apparatus is provided with at least one encoder to set the cutting rail. A method for setting the position of a cutting rail of a working device, such as a mulcher, relative to a working rotor, is configured in such a way that the rotational speed of a drive shaft and the rotational speed of the working rotor are measured and compared with one another. When a ratio of the rotational speeds differs by a predefined threshold, a change in the position of the cutting rail is brought about.

Abstract: The bottom of an expansion form is carved to approximately match the contour of the bottom of a crack or joint, while the top is allowed to “run wild” above the surface level. A generous bead of flexible caulk is applied to the bottom of the crack or joint and the expansion form is gently pressed into the caulk to seal the bottom of the expansion form to the bottom of the crack or joint. The damaged area is backfilled and graded, and the top of the form is trimmed after backfill sets. The lower portion of the expansion form is made from a closed-cell polyethylene foam board with sawed sides, which opens the cells to improve the adhesion of the expansion form to the backfill material. Lateral blocking may be used to support the expansion form upright and following the joint or crack while the backfill sets.
