Grom
Stubble unit

„GROM" ("THUNDERBOLT") - stubbly aggregate, adapted for plain surface processing of soil, immediately after harvest time - it actuates the fast germination of remainders of crop seeds and cockles, enables also the fast decay of post harvest remainders and helps to keep the moisture in soil. Remainders of crop seeds and cockles germinate the best if the soil is shallowly cultivated after harvest. Straw also changes itself into humus much more easily if the stubble field is blended on small depth.

There are the following operating elements of the aggregate:
- special spring teeth with square cross section, finished with double sided coulters or with "goose foot",
- leveling drag manually adjusted or drag made of wire teeth,
- tube roll.

Adjustment of the operating depth is performed by means of changing the tube roll position.
