hello, a friend of mine should restore a land in the hills with moraine, alluvial soil mixed with stones and earth, should create paths and terraced slopes, trace access roads and perform earthworks, for this he had thought of an old tracked komatsu I believe 18 tons of tonnage model: PC180 -NLC5K Komatsu PC 180 LC-3, what do you think of this series of excavators that merits and defects, thanks

I appreciate this is an old post but I had a Komatsu pc150-3
I bought it with a mate of mine for a project about 15 years ago . It had a leg sticking out of the block when we got it so we got a used engine which we rebuilt and stuck it in . We had the pumps reconditioned and we used it for some house sites we developed . We then sold it to a mate who still owns it and it’s still going well .
I think the 150 and 180 were pretty much the same digger and I thought it was a great machine . Very easy to work on as well . I think it might of been one of Komatsu’s first servo controlled machines .

I think they are basically the same machine . I took the pumps off mine and had them reconditioned. It was very straightforward from what I remember .
