Hello. I just joined up here. My first piece of equipment i ran was an older kobelco excavator with a 10 ton removable counterweight. My dad worked at a sand and gravel pit and ran this machine and let me sit on his lap when i was little and dig holes in the sand. Then i later bailed out bottom sand from the pond there. I have been trying to find any pics or info on this machine and cannot find anything. I do not remember a model number ???LC, year 1990 maybe?? 10 ton hydraulic removeable counter weight, orange in color, mitsubishi engine, i remember it to be a pretty big machine. My dad could pull out stuck loaded tri axles with just swing motor. Any info on this machine would be nice as it is the main reason i joined up here. thanks.
