at any distance between the lines on the sowing bodies 23 are placed the sowing pneumatic dosage measurer that with the controlled hydraulic propelling centrifuge turbine 21 and the pneumatic distributor 25 complete the pneumatic sowing system in addition the seed dosing can also be made either by means of mechanic dosing or directly from the hopper the advantage of this self propelled machine with a sowing and or fertilizing device is that the sowing and or fertilization elements may be easily disassembled and therefore by assembling the fumigation and or spraying elements it may become a self propelled fumigator and or sprayer when the self propelled machine is used as a fumigator on the supporting cradle 20 the liquids deposit is placed and instead of the turbine 9 a fumigation pump is placed which is propelled by the same hydraulic command of the air turbine on the lifting 16 the fumigation boom is hung and fixed its technical features are similar to those available in the market in case any other tool is fitted if it has to use the lifting system it may be either fitted in a similar was as described above for the sowing machine and fumigator or by means of a bolt as in any tractor available in the market the fact that the tools kit may be easily disassembled has the advantage of facilitating its transportation since the kit may me transported in a trolley designed for this purpose that may be carried by the machine and respect.
