Within the ground maintenance industry it is known that the rotation of certain materials such as a steel blade or a plastic cord, will effectively cut blades of grass and such. This concept has been incorporated in this device to produce an apparatus that will both cut and trim lawns and properties by simply pushing this machine like a lawnmower When trimming around obstacles such as trees, curbs, fences, tombstones etc.; all you need to do is squeeze a lever that will engage a trimhead assembly with a rotating plastic cord. The trimhead will be located at the left front of the mower base. This will enable to Cut and Trim Mower to go beyond the wheel base width and reach areas not accessible with a conventional lawnmower. This can cut in odd locations without excessive bending down. The Cut and Trim Mower is distinct from the standard lawn mower because it functions as a weed and garden trimmer similar to a weed eater and at the same time cuts grass. There are a number of features novel of this device. First: one motor operates both the trimmer and the grass cutter. Secondly: the nylon cord trim head assembly can be disengaged without shutting off the motor. Thirdly: this device is safe as no external blade is exposed only a nylon cord. Fourthly: this device uses a nylon cord rather than a steel blade for trimming purposes. This is what makes this device distinct from other patents including United States Patents numbers 4,170,099; 4,242,855; 4,642,976; 4,653,254; 2,917,890; 3,304,700; 3,319,406 and 3,782,085 which the closest patent I believe is 4,170,099 but my device is novel because the blade mounting is inside the mower itself and the drive is also more efficient and sufficient for the purposes needed. Belt drives in some of the devices are not practical for speed required. This is very durable and novel in that it will last much longer without excessive wear and tear. patent 4,170,099 is exposed wire with an unprotected unsafe head.
