An implement for removing rocks and preparing soil for landscaping or seeding includes a bucket attached to the lift arm of a skidsteer loader by an appropriate hitch mechanism. The bucket includes a frame mounted on the outer end thereof which supports removable and replaceable grates having spacing therebetween for allowing rocks to be collected on the grate and dirt collected with the rocks to fall through the grates. Tines extend from the outer transverse edge the frame supporting the grates and are adapted to collect and dig under rocks which are forced up the tines and onto the grate by the normal forward movement of the skidsteer. Periodically, when the grates become full of rock, the operator pivots the implement, thereby dumping the rocks into the bucket. The bucket includes a perforated grated floor through which additional dirt may be removed from the rocks and dropped back onto the soil while the rocks remain in the bucket. Occasionally, when the bucket is full or nearly full, the operator dumps the rocks on a rock pile by dumping the bucket.
Implement for separating rocks from soil including a bucket, a hitch for pivotally connecting said bucket to a drive vehicle for moving said implement relative to soil from which rocks are to be removed, said bucket having an open side, a closed side, and a floor connecting the open and closed sides of the bucket, said bucket including a grating assembly having a ground engaging member separately mounted on said grating assembly, said grating assembly defining openings sized to retain rocks on the grating assembly while permitting soil to drop through the grating assembly, said ground engaging member extending along said grating assembly for removing rocks from the soil and depositing the rocks on the grating assembly, said ground engaging member includes multiple spaced tines projecting from said grating assembly for penetrating soil as the implement is moved, said tines engaging rocks on the soil, whereby movement of the implement forces rocks to move along said tines and onto said grating assembly.
Implement for separating rocks from soil including a frame, a hitch assembly for mounting said frame to a drive vehicle for movement over soil having rocks to be removed, said frame having an outer transverse edge extending transversely to the direction of movement over soil, a grating assembly mounted on said frame, and a ground engaging member removably mounted relative to said grating assembly on said outer transverse edge, said grating assembly defining openings sized to retain rocks of a predetermined size on the grating assembly while permitting soil to drop through the grating assembly, said ground engaging member extending along said outer transverse edge for removing rocks from the soil and depositing the rocks on the grating assembly.
