2. The Problem Landscaping is a common enjoyment among homeowners. Heavy boulders are very common on property; however, almost impossible to move. If one wants to move a heavy rock, they have 2 choices: 1. use brute force and risk hurting themselves 2. rent a bobcat, figure out how to get it home, tear up the grass moving it, etc Neither option is very easy or practical.

3. The Goal create a cart capable of loading and unloading a large rock, and relocating it to different places within the yard. It would be designed to accommodate up to a 300 lb rock. to be able to be used for anything else that is heavy or cumbersome to move; similar to the function of the flat carts that you push around in Lowe’s or Home Depot while shopping. Our idea would be marketed to the average homeowner with landscape needs. The individual could either rent or buy this device and easily store it in a garage or shed when not in use.
