) ( not shown ) which goes through a frame hitch pin hole ( 12a1 ) in a frame longitudinal member ( 12a ). the frame longitudinal member ( 12a ) is securely attached to a frame left transverse member ( 12al ) on one side and a frame right longitudinal member ( 12ar1 ) on the opposite side . the frame left transverse member ( 12al ) and the frame right transverse member ( 12ar ) in conjunction with a frame longitudinal member extension ( 12a2 ) provide a towing means when attached to a right aerator ( 14a ) and a left aerator ( 14b ) at their respective distal ends . the frame left transverse member ( 12al ) is securely attached to a frame left pivot joint ( 12al2 ). the frame left pivot joint ( 12al2 ) is pivotally attached to a frame left rear member ( 12al3 ) and permits the left aerator left end ( 14bb ) to move through a frame left rear member motion ( 12al4 ) upwardly and downwardly when it transverses a bump in the ground . the frame right transverse member ( 12ar ) is securely attached to a frame right pivot joint ( 12ar2 ). the frame right pivot joint ( 12ar2 ) is pivotally attached to a frame right rear member ( 12ar3 ) and permits a right aerator right end ( 14ab ) to move through a frame right rear member motion ( 12ar4 ) upwardly and downwardly when the left aerator ( 14b ) transverses a bump in the ground . the frame left rear member ( 12al3 ) is rotationally attached to the right distal end of a left aerator axle ( 14be ) by a frame left connecting pin ( 12al1 ). the left aerator axle ( 14be ) is rotationally attached to a left aerator axle left bearing ( 14bf2 ) which is further rotationally attached to a left aerator left end ( 14bb ). the left aerator left end ( 14bb ) is securely attached about its circumference to a left aerator drum surface ( 14bd ). the left aerator drum surface ( 14bd ) is securely attached to a left aerator right end ( 14bc ). the left aerator right end ( 14bc ) having a left aerator fill ( 14bb1 ) which is used to add mass to the left aerator ( 14b ), the additional mass increases the penetration of an aerator first spike ( 18a ) into the soil . the left aerator right end ( 14bc ) is rotationally attached to a left aerator axle right bearing ( 14bf1 ) which further is attached to the left distal end of a left aerator axle ( 14be ). the frame right rear member ( 12ar3 ) is rotationally attached to the right distal end of a right aerator axle ( 14ae ) by a frame right connecting pin ( 12ar1 ). the right aerator axle ( 14ae ) is rotationally attached to a right aerator - axle right bearing ( 14af1 ) which is further attached to a right aerator right end ( 14ab ). the right aerator right end ( 14ab ) further comprises a right aerator fill ( 14ab1 ) which is used to add mass to the right aerator ( 14a ). the additional mass increases the penetration of the aerator first spike ( 18a ) into the soil . the right aerator right end ( 14ab ) is securely attached about its circumference to a right aerator drum surface ( 14ad ) on the right distal circumference . the right aerator drum surface ( 14ad ) is securely attached to a right aerator left end ( 14ac ) on the left circumference . the right aerator left end ( 14ac ) is securely attached to a right aerator axle left bearing ( 14af2 ) which is rotationally attached to the left distal end of the right aerator axle ( 14ae ). the left distal end of the right aerator axle ( 14ae ) is securely attached to one distal end of a rake adjusting bracket ( 16a ). the left aerator axle ( 14be ) is securely attached to one distal end of a rake adjusting bracket ( 16a ). the opposite distal end of the rake adjusting bracket ( 16a ) is securely attached to the right aerator axle ( 14ae ). the rake adjusting bracket ( 16a ) is rotationally attached at a midpoint to a rake adjusting screw ( 16c ). the rake adjusting screw ( 16c ) is securely attached to a rake adjusting handle ( 16b ) which when turned in either direction causes the rake adjusting bracket ( 16a ) to move forward or aft . this motion adjusts the rake angle of the right aerator ( 14a ) and the left aerator ( 14b ) relative to the direction of travel of the enhanced agricultural aerator ( 10 ). the rake angle has a significant impact on the degree of soil disturbance produced . the larger the angle the further the away from an aerator first spike ( 18a ) the soil is disturbed resulting in more aeration . this rake adjustment in conjunction with the mass adjustment allows the user to select the proper aeration for the soil condition . secondly , referring to fig2 which is a rear view of an enhanced agricultural aerator ( 10 ) being pulled by a farm tractor showing the right aerator ( 14a ) and left aerator ( 14b ) in several roll positions ,

rake adjusting bracket ( 16b ), rake adjusting screw ( 16a ), rake adjusting handle ( 16c ), and farm tractor ( 24 ). the enhanced agricultural aerator ( 10 ) is removably attached to a farm tractor ( 24 ). as the farm tractor ( 24 ) tows the enhanced agricultural aerator ( 10 ) over uneven ground the left aerator ( 14b ) moves through a left aerator drum roll position motion ( 22b ). the motion from a left aerator drum roll position 1 ( 22b1 ) to a left aerator drum roll position 2 ( 22b2 ) and finally to a left aerator drum roll position 3 , caused by the terrain , results in the left aerator ( 14b ) flattening the soil . as the right aerator ( 14a ) moves through a right aerator drum roll position motion ( 22a ) the motion from a right aerator drum roll position 1 ( 22a1 ) to a right aerator drum roll position 2 ( 22a2 ) and finally to a right aerator drum roll position 3 ( 22a3 ), caused by the terrain , results in the right aerator ( 14a ) flattening the soil . the left aerator drum roll position motion ( 22b ) and right aerator drum roll position motion ( 22a ) repeatedly applied over the extent of an entire field results in the field terrain becoming more smooth . the rake adjusting handle ( 16c ) is securely attached to the rake adjusting screw ( 16a ) which is rotatably attached to the rake adjusting bracket ( 16b ). turning the rake adjusting handle ( 16c ) rotates the rake adjusting screw ( 16a ) which causes the rake adjusting bracket ( 16b ) to move which changes the rake angle of the right aerator ( 14a ) and the left aerator ( 14b ). referring to fig3 a which is a perspective view of a first embodiment of a spike welded to an aerator drum surface exhibiting the following features : aerator first spike ( 18a ), aerator first spike center crease

aerator first spike side ( 18a2 ) to the aerator first spike forward side ( 18a3 ) at an aerator first spike angle ( 18a8 ). the aerator first spike angle ( 18a8 ) between the aerator first spike side ( 18a2 ) to the aerator first spike forward side ( 18a3 ) provides ridged the aerator first spike ( 18a ) so that it will not bend when subjected to side loads along an aerator first spike load direction ( 18a9 ). now referring to fig4 a which is a perspective view of a second embodiment of a spike welded to an aerator drum surface exhibiting the following features : aerator second spike (
