Abstract: The invention relates to the field of land mines and in particular to devices and techniques for neutralising and/or retrieving land mines. Existing mine retrieval/neutralisation techniques include mechanical excavation or shaped charge attack and such techniques are either susceptible to blast damage in the event of inadvertent mine explosion or can produce ambiguous results (i.e. an operator can be unsure as to whether a mine has been successfully attacked or a non-mine target has been attacked in error). The present invention provides a mine retrieval technique that involves spearing the mine for later retrieval to the surface.
Abstract: A mine stripper with numerous plow blades that rotate as they dig deeper to achieve an equilibrium depth of about nine inches and a basket that presses against the top of these blades to receive dislodged mines while sifting away attached soil.

Abstract: A turf product having a base (11), a root zone material and a reinforcement material (15) located thereon and turf growing in the root zone material (13), the base preferably being the upper surface of a pallet (10). The invention also includes a method and means whereby the turf can be located temporarily in position whilst on pallets and one in which the turf can be placed on the ground surface by locating the turf on a pallet in the required position and then removing the pallet from thereunder.
Abstract: A rock rake fiber gathering into a row or a gathering area objectional rocks and debris from the ground where a first roller engages such rocks and debris and a deflector forms a gap therebetween through which only un-objectionable rocks and debris may pass. The adjustable rock rake having an actuator for adjusting the angle of the roller and deflector. The adjustable rock rake having guards about the end of the roller such that a gathering area is formed for the accumulation of rocks and debris. The guards being removable and storable upon the frame of the adjustable rock rake.

Abstract: A ground raking attachment for bucket-equipped tractor includes a toothed, cylindrical rotor which works the soil and at the same time rakes the ground free of rocks, refuse, roots, sticks and other debris which is transferred to the tractor bucket by the action of the rotor.
Abstract: This rock picker invention is a towable farm implement which is capable of removing rocks from a farm field. A plurality of buckets scoop up quantities of soil as the rock picker is towed by a tractor. The buckets are mounted on a pair of cables which pass over guide wheels. The cables are forced to move by a power source so that the buckets are forced into, across and out of the ground. The guide wheels are mounted on axles on a conveyor frame which allows the buckets and cables to be lifted to a transport position and which allows the angle of attack between the buckets and the ground surface to be varied. The buckets are equipped with openings and shaped such that soil falls from the buckets when the buckets are lifted. The cables are guided such that the buckets are caused to invert and dump the rocks collected into a hopper. The hopper is equipped with a lifting linkage to allow transfer and disposal of rocks collected.
Abstract: A ground-raking attachment adapts bucket-equipped tractors for raking a ground surface free of rocks, refuse, roots, sticks and other debris. The attachment includes a frame and means for pivotally mounting the frame on a tractor bucket. The frame mounts at least one pair of motor driven, rotatable shafts mounting a plurality of rake teeth arranged for raking debris from the ground and progressively advancing it into the bucket. A frame drive is connected to the bucket for angularly adjusting it to selected positions relative to the ground.
Abstract: The device is pulled behind conventional sod cutting apparatus and includes an angled roller that diverts the various sod rolls sequentially discharged from the apparatus, doing so to one side of the path traversed by the apparatus. The device also includes a frame having ground supports for supporting the roller at a slight elevation above the ground so that the roller is free to rotate in a direction determined by the still moving rolls of sod. Provision is made for optimumly adjusting the roller angle and once adjusted to maintain the same angle when changing the setting back and forth to divert rolls either to the left or right. The device also includes a hitch by which the device can be quickly unhitched at the end of each run to permit the sod cutting apparatus to be turned around more readily. Also, the roller supporting frame is adjustable to accept rollers of different lengths for accommodating sod rolls of different sizes.
