A rotary movable agricultural implement, especially a circular spike harrow (3) has a parallel implement moving in a straight line (4) and supplied from the same power source (5). The two implements are relatively adjustable in height. One of the two implements has tines with flexible ends and which have a pitched roof shape with side edges crosswise to the direction of travel. Rollers or discs (24,25,26) support the implements on the ground. A seed-drill or planter is positioned between the rotary and straight-moving implements
