A system may dispense a marker, determine location data or time data, and substantially simultaneously trigger the dispensing of the marker and logging of the location data that identifies a geographic location at which the marker is dispensed or the time data that identifies a time at which the marker is dispensed.

An apparatus and method are disclosed for efficiently removing a belt from a drive assembly of an agricultural implement in which a flywheel and a header framework cooperatively define a gap therebetween which is smaller than a cross- sectional dimension of the belt and thereby prevent the belt from being simply passed through the g ap and removed from the remaining components of the drive assembl...

A bathrobe structure (1) is formed by weaving threads extending in one direction with other threads extending in a direction generally orthogonal to the former, to form certain patterns; said threads consisting of microfibers (3) and (4). The weaves may be of plain type, of twill type with oblique ribs formed by the offset between interlacings or of satin type, i.e. with looser weft and warp inter...
