Komatsu PC20 Mini Digger 3 Ton Self Build

Komatsu PC20 Mini Digger 3 tonGood selection of buckets with the machineIn good working order apart from the tracking seems not as powerful as it should be(there is wear in the rollers underneath that the tracks run on and the sprockets, but it was like that when I got 20 years ago and it still works ok) I have built 2 self build houses without any problems with the machineThe dipper and bucket rams were reconditioned recently (new rods and seals)I don't know how old the machine isObviously this is an old machine and has wear in joints and pins etcStarts and runs wellThe hour meter was on about 4000 hrs when I got it so seems to work as its on 4669 nowWill need to be transported by the buyer from near OxfordCash on collection
