The 365 Cat someone posted on here said it was a Perkins. Probably stamped Cat.
All three of my current skid steer and CTL machines are SCR (one of those 3 is new so that isn't really fair to use that as an example). I had one issue with the SCR on a 2018 model that was covered under a fix it program a couple months ago. The other 2 machines that we no longer have, did not have any SCR issues. While an SCR machine will have a higher likelihood of having more issues (simply because there is an opportunity for more things to go wrong), I have not seen issues to speak to. Honestly, I think is how they are run, and the engineering is what makes some better than others. Kubota and SCR has not been a great fit for whatever the reason, but when every machine that runs the Kubota 3.8 sees issues, that says something about the engineering that went into the design. Kubota, Cat, and Takeuchi all are known to have issues running the same engine.
