This invention is a manually operated tool for increasing the efficiency and decreasing the effort attributed to common garden leaf rake. The invention is a tubular shaft with a handle on the upper end and a wheel at the bottom end to which half way down the shaft, at a calculated angle, attach one or t wo common garden leaf rakes. By applying simple physics, namely the leaver, it transforms a common garden rake into a "Super Rake". Thus increasing output efficiency and decreasing input effort. By taking advantage of the leaver principle, (example the manual can crusher , or a nut cracker), it can increase the force on the rake, the exact calculation of force is irrelevant, the object is to illustrate the scientific principle which applies to the "Super Rake". By taking advantage of less effort, we can double the efficiency by attachin g two rakes thus covering twice the area, while maintaining minimal effort.
