hi, sorry if I disturb, you would have information and technical data of the fiat fl 12 crawler loader, there are various series from the fiat, fiat allis version, fiat hitachi version, the fiat fl12 and 14 have the same crawler undercarriage, it is similar I believe to the caterpillar 951, it was built from the 60s to the 90s, first of all fiat, then fiat allis then fiat hitachi, fiat kobelco and adessonew holland I believe they no longer build them, it was replaced by crawler excavators, I believe that new hollan and first fiat kobelco build only a few models of tracked bulldozer, let me know thanks, besides the models made the chronology, in my part some farmers use them in the countryside to plow and till the uncultivated fields.
