The ballast to add is calculated with the formula
Gv min. = (Mb tot x (C + Lb tot)) – (Tv x B) + (0,2 x Te x B)
-----------------------------------------------------------------
A+B
The distance from the center of gravity of the combi machine to the lower hitch of the tractor is calculated with the formula
Lb tot = (Lb1 x Mb1) + (Lb2 x Mb2) + (Lb3 x Mb3) + (Lb4 x Mb4) + (Lb….x Mb….)
------------------------------------------------------------------------------------------------------
Mb1+Mb2+Mb3+Mb4+Mb….
The overall weight of the entire combi machine is calculated with the formula
Mb tot = Mb1+Mb2+Mb3+Mb4+Mb…..
On the front bridge of the tractor it must, in any case,
burden at least 20% of the total mass tractor-tool in
march order. It is however to hold present that, beyond
to the appropriated one chosen the connection tractor-
tool, the application of ballasts in front position, the
limits and with the modalities indicated from the
constructor of the tractor, can improve of the stability.
Moreover, with firm tract or it must be made to come
down to earth the toolavoiding
therefore possible involuntary reductions,
improving some, at the same time, the stability.
