A thatching attachment for a rotary power lawn mower that uses short lengths of nylon trimmer cord as bristles to thatch lawns by mounting the brushes on a blade. The device uses alternatives to bristles and new arrangements of the blades to better groom lawns overall. The new thatching elements work on all types of grasses and perform better than plain nylon bristles. Moreover, these thatching elements last longer and are, therefore, more economical. Finally, my new designs are better at mulching the cuttings, which reduces the amount of waste picked up by the mower. This saves time and cost of bagging and disposal of the waste.
