They are machines for working the land in order to create the best conditions for the growth of the root system of the plants as well as to unroot weeds and to inter manure that has been previously spread over the land.
The rotary tiller is a carried machine and driven by the tractor through three point linkage.
It consists of a horizontal shaft (rotor) on which are fitted the rotating units (weeding hoes) taking their motion from the tractor P.T.O. by a cardan shaft and through a reduction angle gearbox and a side chain transmission or with gears.
The required powers strictly depend on the work width of the machine and on the work depth of the weeding hoes and of the type of the land: from 20 up to 100 HP for widths between 800 and 3000 mm.
The number of revolutions needs by the rotor oscillates in a range between 150 and 200 rev. per min. depending on the nature of the land and on the kind of work required.
CHOICE OF THE PRODUCT
In order to supply the most suitable product, it is necessary to keep in consideration the following details.
The differences between a unit with a gearshift and a unit with only a single speed is that with the former there exists the possibility to get the most fit work speed to the rotor depending on the kind of the land, on its characteristics and on the chopping result required.
The approximate power needed by the gearbox can be determinated according with the following formula:
N = i * L * h
Where: N: requested power in KW
i: experimental working index in KW/m*cm.
L: width in meters
h: work depth in cm
Approximate working tractor speed 2/4 Km/h and working depth between 14/30 cm.
