Grass cutting chain saw drive system

The combination of a grass cutting adapter and a chain saw drive comprising:

• the chain saw drive including a motor with an output, a frame holding the motor and having at least one attachment point proximate the output;
• the grass cutting adapter including a cutter head, means for rotating the cutter head, including:
• a flexible shaft, means for connecting the flexible shaft to the cutter head, means for supporting the flexible shaft rotatably including a tubular member inclined at an angle below the horizontal in a downward arc terminating at the lower end proximate the cutter head in a vertically downward aspect, the lower end of the tubular member having a constriction of the bore thereof, a sealed anti-friction bearing having an inner race and an outer race positioned in tubular member lower end with the outer race thereof proximate said constriction, at least one spacer extending upwardly in the tubular member from the anti-friction bearing, a second bearing resting on said spacer, a second spacer above said second bearing, the flexible shaft having a downward facing shoulder resting on the inner race of the sealed anti-friction bearing and extending upwardly through the second bearing to said output, means for coupling the flexible shaft to the output including means for attaching the supporting means to the attachment point, comprising a bracket extending from the attachment point laterally past the output and fixing the upper end of the tubular member proximate the output, and means for manually grasping said combination for grass cutting comprising a first handle extending from one end of the combination and a second handle extending from an end of the combination opposite the first handle.
