Nice looking welds.
You must be your own contractor to own a super duty Takeuchi excavator. My local Rural Electric Cooperative, only uses that brand (here in Iowa, US), they don't break down. Per the foreman, who's my neighbor.
Cat brand stuff is made in the next state east. Could be "right to repair" is a better reason. All these major US construction machinery companies with custom everything (like fuel filters, with special monitors only sold by dealers), but OBD is proprietary, and only dealer can service. And they own the software in the machine, per the sales contract. I wonder is this a universal thing in all manufactures of equipment with environmental computer control for minimal emissions, which gave them license to make a mega money pump?
