One of my first jobs to break in my CK30 was mowing a 6 acre bumpy field that took 10 hours. I was sure to adjust the rpms between PTO540 and about 2000 as I went along. The field was tall but the tractor wasn't lugged since I was going so slow due to terrain.
Check the radiator screens often, they will accumulate junk and lead to overheating.
Driving on the road is a 2wd job. Also, go kinda slow since the bumps in a road will bounce a suspensionless tractor pretty good. Flashers, seatbelt, etc. are good.
I have actually noticed pretty substantial front tire wear on my tractor after the first 200 hours. I do not run on any asphalt but use 4wd most of the time and my dealer thinks the scrubbing is wearing them out. He and I both measured the toe in and it is within specs. It's not enough to need replacement but noticeable. The big rears still look new.
Put the tractor to work and enjoy the nice swish sound of the blades cutting through grass. Check oil and note that your fuel gauge will stay full and then all of the sudden go down quickly to empty.
