hi excuse me if I disturb, at a tractor mechanic in the area there is a caterpillar brand mini excavator model 303 for sale, I think the series is CR or GR, I don't remember well, the livery and paint of the machinery in question is faded and discolored scratched by wear from time and blows. it has rubber tracks with traces a little worn, by eye I moved the arm with my hands and I noticed a bit of play in the connection of the fifth wheel support arm, very evident, what do you think of this machine? what merits and fears it would have. what market price would the engine be a mitsubisci, I did not ask the mechanic with interest, I thought before I inquired, we will have to transport it on an old Fiat truck for agricultural work in the countryside. thank you.
