I am looking into possibly buying an older Koehring 6633 excavator that is located in North East, Maryland, 21901. Please let me know if you are interested in looking this machine over for me. Thank you. Here in the link to look it over the pictures that the seller is making available. https://www.machinerytrader.com/lis...uipment/for-sale/191654083/1988-koehring-6633
Check if you can find local mechanic who can inspect machine
You are smart to be looking for a qualified person to look at it. On top of everything else hammer life is extra hard on any machine.
