. Agricultural engineering; a text book for students of secondary schools of agriculture, colleges offering a general course in the subject and the general reader. Agricultural engineering. 208 AGRICULTURAL ENGINEERING level, is worthy of consideration. In Europe, the reversible plow has been in more extended use than in this country. The moldboard type of reversible plow consists of two plow bottoms, a right- and a left-hand, which are used alter- nately. These plows do not have many of the conveniences of the high-lift sulky and do not possess the usual provisions for relieving the landside friction by placing the load on the carriage. It is, however, an entirely practical tool. The reversible disk plow is so arranged that by swinging the team and hitch about to the opposite direction, the inclination of the disk is changed, but the carriage is left unchanged and is simply drawn across the field in the reverse direction. It would seem that this implement has reached a higher state of development than its moldboard mate. Tractor Gang Plows. The use of the tractor for plow- ing requires for the best service special plows adapted to. Fig. 118. An engine gang plow. the special requirements of tractor power. Tractor gang plows are made with moldboard and disk plows and range in size from two to fourteen furrows. In general there are two types, one the flexible beam shown in Figure 118, in which each plow or pair of plows may be handled independently, and the rigid beam, Fig. 118a,.
