The rear tractor ploughs
are among the essential tools for those you have a field to cultivate. The most ancient agricultural tool in history has always been used in the soil tilling and the preparation for sowing by ploughing, aerating and tilting the soil. It is also very used for the preparation of the soil for the following cultivations.
The tilling by means of the plough can be classified in:
- cultivation:deforestation, trenching, hydraulic arrangements, etc.
- preparatory (perdiodical):Preliminaries: scarification, chopping, etc. - Complementaries: grubbing, harrowing, soil rolling, etc.
- consecutives (with plants already present in the field):weeding, earthing up, etc.
The rules to follow for a perfect ploughing are the traditional ones:
- the cut made by the plough cutter has to be clean and vertical;
- the cut made by the ploughshare has to be horizontal (that is to say without steps) and doesn't have to dent the wall of the previous groove;
- the tilting of the clumps has to be as complete as possible; the fertilizer (and the manure) on the soil like grass have to be well underground;
- the groove behind the plough has to remain clean (without the return of ground);
- grooves have to be linear and parallel and with the same depth, perfectly joint one to the other so that there is no hard soil between them;
- the tilling on the head (or finishings) have to be carried out by means of crosswise grooves that level the soil off and give to the head a slight inclination towards headland;
