An encyclopædia of agriculture [electronic resource] : comprising the theory and practice of the valuation, transfer, laying out, improvement, and management of landed property, and the cultivation and economy of the animal and vegetable productions of agriculture, including all the latest improvements, a general history of agriculture in all countries, and a statistical view of its present state, with suggestions for its future progress in the British Isles. Agriculture. Book IV. LEVELLING MACHINES. 419 long, 3§ inches broad, and five eighths of an inch thick at the back. The curves of the blades are formed to a circle of 40 inches diameter. (High. Soc. Trans, vol. vii.) 2716. The Sithney scarifier, or hash, consists of a cylinder with many circular cutters, or a number of circular cutters connected together upon one axis, which is intended to pass over the ground, for the purpose of scarifying or cutting the surface of grass land, perpendicularly, to the depth of a few inches, and to any required degree of fineness. By means of this scantier, or hash, the roots of old grass may be effectually destroyed without the labour of ploughing, which is calculated to enable the farmer to graze the land much longer, previously to breaking it up for wheat or turnip tillage. The apparatus is proposed to be connected to the hinder part of an ordinary cart; or the axis of the cylinder, or circular cutters, may be supported by two iron arms, attached to the axletree with a pair of common carriage wheels. When this machine is used for renewing lawns or grass land, it will then be necessary to fix above the cutters a box containing grass seed ; which box must be perforated with small holes, one hole being exactly over every cutter, so that the seed may fall immediately into the furrow produced by the cutter. (Newton s Journal, vol. i. p. 250.) 2717. The only essential roller for general purposes is the parted cast-iron roller, with a scraper and box over (Jig. 359.). Sect. V. M
