The best luck I’ve had breaking in a new motor is the following:

30 minutes about 1/3 governed speed, no load
20 minutes 2/3 governed speed, no load
20 minutes 1/2 governed speed road gear on level road
20 minutes full throttle road gear on level road
30 minutes full throttle 1/3 load
30 minutes full throttle 2/3 load
30 minutes full throttle full load (not overloaded) engine should maintain rated RPM 90% of the time.

After the above, work the tractor like normal varying load and engine speed and avoiding prolonged idling and overloading the first 100 hrs or so. I like to use light oil (10-10W) the fist 10 hours changing oil and filters at 10, 50 and 100 hours. After 10 hours use oil you normally would use.

Good luck.

I have noted that prolonged light loads especially on diesels does not seat the rings very well.
