Abstract: A tiltable bucket assembly having a working edge on the leading end of the bucket and a forward extending extension arms, a pair of support arms, a pair of first wheels, a pair of second wheels, a pair of bucket-rotational members, a bucket-pivoting member, a bucket-linking arm, and a displacement body having an output shaft disposed therein. The support arms are connected at one end to each corresponding first wheel and extend forward from the corresponding first wheel. The extension arms are connected to the support arms at a point away from the first wheels. The bucket-rotational members are attached at one end to the bucket at a point away from the working edge. The other end of the bucket-rotational members are linked to the corresponding first wheels so that vertical displacement of the first wheels result in a substantially equivalent vertical displacement of the other end of the bucket-rotational members.

Abstract: A spray cultivator having a frame with unequal rigid side elements pivotally connects to define between pivots a parallelogram with opposite sides equal and parallel. The frame is fixed by a first side element to a lift bar of a prime mover for pulling the cultivator over level and non-level fields. The remaining three side elements comprise the remaining parallelogram sides and the free ends thereof extending downwardly and rearwardly beyond the pivotal connections of the parallelogram. A second side free end engages level and non-level field surfaces with a sliding shoe. A third side free end that is parallel to the fixed first side element supports a spray pipe and nozzle that is continuously perpendicular to a field's level and non-level surfaces at a constant height thereabove responsive to the field surface engagement and pivotal parallelogram connections of the frame side elements.

Abstract: Apparatus for mounting on the front of a tractor, combine or other land vehicle which is useful for gathering chunks, twigs, branches or other debris from the soil. The apparatus, constituting a chunk gathering machine, is comprised generally of the combination of a rotary rake mechanism and a collection means, or pan, into which chunks, twigs, branches or other debris is swept by the rotary rake mechanism as well as means for dumping, or discharging, the collected debris.
