A calibration block provides a deck with a slot for receiving a first plate for supporting a distal end of the planter unit when setting its gauge wheels, whereby the first plate is flush with the deck at a predefine distance from the soil. The calibration block also provides a gauge block and associated second plate for increasing the predefined distance.

A method for measuring the milling depth of a road milling machine, the machine being operative to mill a ground surface with a milling roller lowered to a milling depth to create a milling track, the machine including at least one side plate located to at least one side of the milling roller to engage an untreated ground surface, and the machine including a stripping plate operative to be lowered onto the milling track generated by the milling roller. The method includes measuring the milling depth of the milling track, the measuring including detecting a measurement value of a ground engaging sensor engaging the milling track.

A precision depth measurement device precisely measures pocket depth and seated primer depth for consistent ammunition production. The device includes a drop indicator having a stem. The stem has an outer peripheral surface. A hub is annular having an inner perimeter surface. The inner perimeter surface is complementary in size to the outer peripheral surface of the stem. Thus, the stem of the drop indicator is insertable into the hub. A collar is removably couplable to the hub. The collar has a collar lip extending inwardly from an internal surface of the collar. The collar lip defines a collar opening at a base end of the collar. The collar opening is complementary in size to an ammunition casing wherein the collar receives the ammunition casing and holds the drop indicator in a perpendicular position relative to the ammunition casing.

The present invention relates to a method for positioning a milling drum box of a ground milling machine, in particular of a road milling machine, a recycler or a stabilizer, arranged on a machine frame relative to the ground, comprising the steps of: detecting the presence or absence of a ground contact, in particular in a region located in the front or a region located in the rear in the working direction (a), of at least one side plate of the milling drum box of the ground milling machine, and controlling a lifting and/or a lowering of the machine frame depending on the detected presence or absence of a ground contact. The present invention also relates to a ground milling machine for carrying out the method.

A measuring device for inspecting a hole, which can favorably be mounted on a riveting robot adapted to insert a rivet into the hole after inspection. The measuring device includes a test mandrel having a hollow housing and interacting means, whereby the relative position of the interacting means can be detected to determine characteristics of the inspected hole. The measuring device further includes a bushing which is arranged movable relative to the test mandrel.
