The entries in the division for Swing Ploughs, Class 4, were 
numerous. 
In addition to the other com.\iei\iors, Messrs. Murray and Bobinson appeared. 
The lattei', a local celebrity from Sutton, near Hull, showed a wooden plough 
fitted with steel breast fittings. The ordinary coulter was replaced by a large 
revolving knife or wheel, which cutting deep caused a very neat furrow slice 
at the expense of considerable power. The dynamometer told a tale, as will 
be seen by a glance at the results given in Table 1. (lacing p. 538), column 14. 
The plough made verj' equable work, but was not approved of by the Judges 
on account of its liability to derangement from wear and tear. The"stilts are 
strengthened by iron straps. The slade is long, 3 feet 2 inches, Avhich partly 
explains the accuracy of the work. On the land-side of the share a cutter is 
attached, which is intended to assist the action of the revolving disc. The

beam is 4 x 4J inches. The total length, including stilts, is 12 feet 6 inches, 
of which the latter comprised 7 feet (J inches. Nothing in the class made 
better work ; but the heavy draught put it out of court. 
Joint Hodgson, of Louth, Lincolnshire, exhibited No. 1721, comprising an 
iron beam and wooden stilts, a strong useful implement. The ordinary coulter 
was displaced by a small disc wheel.
