1 DESCRIPTION
1.1 PURPOSE
The basic version of the machine is a scarifier
intended for use in gardening environments. The blade
cylinder is designed for ripping moss and weeds -
complete with their roots - out of the soil and for
loosening the soil.
With the additional tine cylinder, the machine can be
converted to a lawn dethatcher in just a few steps.
When used as a dethatcher, the machine is primarily
used to remove thatch from small-scale, residential
lawns and home/hobby gardens.
