(1) Two dimensional force to Plowbody is calculated in this paper, considering about transmitted force (cf. Report II).
(2) The x, y components of force to Plowbody, Wx, Wy, will influence traction force.
Q=Wx+μWy is included in the equation of traction force, so Q is called Plowbody resistance, say.
Q will be got by equation (3) in decimal form.
(3) As Plowbody curve is represented by simple curve or connected curve (cf. Report I), Q will be got by equation (4) or (5) respectively.
(4) By some calculation as to some Plowbody curves, Q will increase as radius of curvature at share point, Plowbody height increase or share angle decrease respectively.
(5) A design of two dimensional Plowbody curve is illustrated, and Plowbody resistance, traction force and average radius of curvature about designed curve are examined.
