a solvent, such as turpentine, added to paint or varnish to dilute it, reduce its opacity or viscosity, or increase its penetration into the ground

Any volatile liquid that lowers the viscosity of a paint or varnish, and thus make it flow more easily; it must be compatible with the medium of the paint; the most common thinner is turpentine.

a device for thinning sugar beet sprouts. It may be used in both irrigated and nonirrigated regions of beet cultivation. The thinner consists of L-shaped blades attached to cutters and disks. The USSR produces four-, six-, eight-, 12-, and 18-row thinners. As the thinner moves along the row of plants the cutters, rotating on a plane perpendicular to the direction of the machine’s movement, make slanting cuts in the rows to a depth of 3–4 cm, loosen the soil, and kill weeds in the vicinity of the row. Half sweeps secured on beams in front of the cutters cultivate the interrow spaces at the same time. The thinner is grouped with tractors in the 1.4- and 2-ton class. The cutters are driven by the machine’s supporting wheels. Thinners similar to those in the USSR are used abroad.
