Congrats on the Branson. Great machine. As far as the engine, many years back Cummins needed a supplier for the smaller A-series engines. Kukje went after this contract and designed and got an engine series approved by Cummins. Cummins has pretty stringent standards, but Kukje made the grade. So they sell the engine as a Cummins, and then they also install it in their tractors. They are not noted as Cummins on the engines installed in the tractors, although the numbers are all the same, like A2300, etc. And I believe them to be the same as the Cummins labeled units. But to put the Cummins decal on the engine and get the max benefit of that branding requires a payment to Cummins for each engine. That label has some value. So I guess you can say it is identical to a Cummins A-series, but is not actually branded as such. But the engine rolls off the same assembly line with the same parts.
On the LS, someone noted that it is a Mitsubishi designed engine built by LS. I suspect that LS simply buys the engine from Mitsu and installs it in their tractors. I really doubt they build that engine. Mitsu, Kubota, Yanmar, etc., are all commonly bought engine to put in industrial and commercial rigs. All are good.
The 4520R is a sweet tractor, you will enjoy it.
