The manual for the
B2630/
B3030 states to operate the tractor for the first 50 hours at a slower speed and
avoid excessive work or operation until the various parts become "broken-in".
It goes on to say,
To obtain the maximum performance and the longest life of the tractor, it is very important to properly break-in your tractor. In handling a new tractor, the following precautions should be observed.
Do not operate the tractor at full speed for the first 50 hours.
Do not run the engine at speeds faster than necessary.
The terminology is a little vague, but they certainly don't want you to run at WOT during break-in.
