What is the best way to add a hammer to this machine? I have the thumb and a wain roy style coupler. Is there some sort of adapter that goes from the coupler to a plate on a hammer or something?
Yes. Wain Roy or Tag or several other bucket manufacturers make a hammer cap for that style coupler. Just need to know the model of the hammer.
You can get a hammer with the wain Roy already built in. United Rentals usually has some for sale. I have one myself that works on my TB240, and 153FR. I no longer need it now and want to sell it.
I bought online from Dave Langafels at Langafels Equipment company, I told him I needed an NPK ph3 to match with a TB260 with tag wain roy style coupler. He sold me a central fabricators top cap. Lead time was about 6 weeks. That was about January 2022.
