Attention is drawn to the following places, which may be of interest for search:
In subclass A01B all relevant details of tools, methods, implements or parts of agricultural machinery which are used for an action that will result in furrowing, ploughing, tilling, moving, opening or smoothing the soil should be classified here. Some of these parts, tools or methods may not refer directly to a blade for working the soil, but will be, however, directly related to the soil working action, like guiding the machine to work the soil according to a planned path or at a constant depth which are related to the steering of, to the connection or hitch to the tractor. Double classification in other subclasses, like in subclass A01C, is allowed depending on the details. For instance, a coulter for a seeder which has a seed pipe attached, the coulter having no detail relevant for the soil working classification scheme, will only be classified in group A01C 5/00. However, a coulter for a seeder, even if it includes a seed pipe, whose action in the soil is described in detail or has some special feature for working the soil, e.g. opening the furrow, may be relevant for subclass A01B.

There is no clear technical distinction between a harrow and a clod crusher. Here we classify, in order to make a distinction, harrows which are explicitly used for clod crushing and/or stone crushers for agricultural purposes (note that stone crusher is different from stone gatherer/remover, A01B 43/00). Double classification is possible for other details of the harrow. Clod crushing rollers can be also classified in A01B 29/00 attending to specific features covered there.

Preventing overstrain |
When pulling soil working elements, like ploughs or subsoilers, the tractor must provide a certain tractive force while maintaining constant speed. This may be important for some soil working actions in which soil working tools rotate at a speed which is dependent on the forward speed of the tractor. Also for achieving a homogeneous soil working with certain tools when soil compaction or resistance conditions change from one area of the field to the next. Here the resistance of the soil to penetration of the tools is measured, and the motor is adjusted to maintain constant speed or power.

The steering referred to here is normally either automatic or semiautomatic (assisted guiding), so that the soil working follows a more precise path (following marks, or trenches created beforehand, so that soil working takes place in precisely parallel tracks, or follows a desired pattern).
