Stair Climbing Wheel Set for CRB

[Hoss]

Thanks. I have the cart that goes with the TM4, but saw the stair climbing wheels as an option at another site. Maybe they just attach to the dolly and replace the stock round wheels. There is no description, just a picture showing two sets of wheels with three small tires on each coming out from a tri-spoke. Not sure how that would be an improvement over stock round wheels for transport and wanted to know if they would be used instead while operating the machine on stairs.
