Roller with a semi-hollow tyre for a farming machine, in particular a roller which can be combined with a seed drill or a soil-preparation tool

摘要

The roller (10) has a tubular support structure of a horizontal axis rotatably mounted on a tractor-drawn support frame with a series of semi-hollow tires (12). A framework is made of a set of bars e.g. flat bars, joined together by two circular end cheeks (32) between which the bars extend axially. The tires are mounted on the bars of the framework with an assembly, where the tires comprise inner surface axially oriented notches.
