Abstract

888,313. Agricultural implements. ETABLISSEMENTS HUARD. July 2, 1958 [July 2, 1957; March 27, 1958], No. 21190/58. Class 6(1). [Also in Group XXIV] The plough bodies of a reversible plough are rotated after the plough is lifted by means of a lever 40a provided with a pawl 43 which engages in a notch 42c in a member 42 fixed to the plough shaft 6c. The lever is operated by means of a link 19 connected to a lever 20 connected by a link 23 to a lever 10 to which the top link 3 of the three point linkage is attached. Rotation takes place after a bolt 12 is manually withdrawn from engagement with a catch 6b on the plough frame. After rotation the catch 6b is engaged by a similar bolt on the other side of member 5a. In a modification the pawl is omitted and a lever 18 abuts against the end of shaft 6c for part of the rotation of shaft 6c, the lever riding over a cam 16 to clear the end of the shaft at the end of the rotation of the shaft.
