I changed it at 48, currently have ~140. So almost 100hrs.
I'd say that your oil choice was fine. thanks!!

Rotella T6 5w-40
There is a thread on here about blowing up your turbo by using high viscosity oil during the winter. I run the Rotella T6 5w-40 full synthetic in mine and let it warm up a bit before running it, also a minute to cool down when I'm done. No issues here in 250 hours. 5w-30 sounds like a great idea, but as you said, it is not as readily available for diesel engines as 5w-40. I'm not sure why they would tell you to run 5w-30 semi-synthetic. I don't think I've ever seen that for diesel engines. Beyond that, even though it is cold in the winter, the summer months get pretty warm, so I would be leery about running a 30-weight oil.
I don't have a block heater either, but I will most likely add one as it is easier on the engine to preheat it when it is cold out.

I am guessing that they were told this by the engineering staff (who probably has never changed oil in anything in their lives) and if you ask them about anything other than what they were told, it is a no from them.
I believe that engineers who design vehicles of any kind, enjoy making the lives of mechanics horrible. Either that or they simply never actually work on or build the vehicles they design.
I am sure that 5w-30 semi-synthetic engine oil will work perfectly fine in these tractors. But the differences between 5w-30 and 5w-40 are minor. And between the two, I'd lean toward the 5w-40. Check out this video explaining why:
