l am looking for an older digger for land drainage and general farm work, have a couple of slatted tanks to dig out. I have looked at a komatsu pc 120 -5 from 1992 or 93, has1100 hours on the clock. Tracks and undercarriage have been fully overhauled lately. Perkins engine seems good. Generally tidy well cared digger for age. It has been on a small building project for a number of years and hasn’t done much. I know the chap who drove it for a week lately, he see’s no fault with it apart from the fact that it is much slower than a Hitachi 120-1. I have a friend who operates a hitachi -1 120, super machine, lively and plenty of power, he thinks this particular komatsu is a slow outdated machine. I know of a komatsu 12 tonne locally with a komatsu engine that gave good service . This machine will be around €10000 which would only buy a rough hitachi. Any advice on the different versions and years of these komatsu diggers and what to look out for would be appreciated. Have access to hitachi buckets, can a quick hitch be fitted to bring the komatsu up from 60 mm to 65ml pins. Looking forward to your replies.
