A soil conditioner for use in combination with a cultivating implement drawn behind a tractor to break up the soil and leave a prepared seedbed in a single operation.

Two sets of axial blade members are provided about each reel. The blades are equiangularly spaced about the axis and are arranged so that each blade of one set is angularly spaced midway between adjacent blades of the other set. The first set of blades include ground-engaging edges spaced a first radius from the axis. The corresponding edges of the remaining set of blades are spaced a second radius from the axis that is less than the first radius. The different radii of the two sets of blades enable the conditioner to be towed through a field, with the freely-rotating blades breaking up clods of dirt left by the cultivator, without the blades becoming clogged with dirt. The conditioner also includes an adjustment structure for elevationally adjusting the blade edges relative to the cultivator. This adjustment structure includes adjust…
