- a generally rectangular main frame adapted to be towed in a direction transverse to a long side thereof;
a towbar detachably connected to said main frame and extending transverse to a long side thereof;
first towbar connecting means on said main frame, positioned substantially midway of a long side thereof;
second towbar connecting means on said main frame, positioned at one end thereof;

Abstract
Disclosed is an agricultural roller useful, for example, in closing and packing furrows after they have been sowed by a seed drill. The roller includes a generally rectangular frame equipped with several roller mounting stations for mounting the desired number of pairs of rollers for a particular use in side-by-side alignment. The frame is also equipped with alternate towbar mounting stations and means for positioning the towbar appropiately for the number of roller pairs employed, and with mounting stations for outrigger frames carrying additional roller pairs when desired. The roller pairs are so mounted on the frame (and outriggers) that they are pivotable in a vertical plane transverse to the rolling direction to closely follow the land contour.
