Sorry for the mundane question that you have all already answered a gazillion times. And it may already be too late to ask since I have about 30 hours on the BX now. I have been running it between 2000 and 2600 rpms, occasionally adjusting the rpms so as not to run at the same rpm all the time. Is this ok or should I run it a little harder? After 50 hours is when I can throttle up most of the way, correct? Thanks in advance for repeating yourselves again. But I didn't see anywhere in the manual that discussed rpm and break in period.

Your engine was likely fully 'run in' at around 10 hours... There is not much to break in on any modern engine, tolerances a lot closer than they were decades ago, better materials and better assemblies.
At 30 hrs,You can use your engine at whatever load & RPM the job requires.

With 30 hours on it, I wouldn't worry about running it harder, I would still vary RPM's from time to time. I go by the manual, but certainly don't baby tractors during break-in.

I have seen lots of treads on break-in and opinions/practice vary widely.

Yea, the only thing it says is on page 26. A little more info would have been nice.

manual said:
OPERATING NEW TRACTOR
How a new tractor is handled and maintained determines
the life of the tractor.
A new tractor just off the factory production line has been,
of course, tested, but the various parts are not
accustomed to each other, so care should be taken 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." The manner in which the
tractor is handled during the "breaking-in" period greatly
affects the life of your tractor. Therefore, 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 start quickly nor apply the brakes suddenly.
- In winter, operate the tractor after fully warming up the
engine.
- Do not run the engine at speeds faster than
necessary.
- On rough roads, slow down to suitable speeds.
- Do not operate the tractor at fast speed.

The above precautions are not limited only to new
tractors, but to all tractors. But it should be especially
observed in the case of new tractors.

Thanks. I must have skipped page 26 in all my excitement. But you're right, doesn't say anything about rpm.

I kept my BX25 a click under 3,000 rpms for the first 50 hours. I think running a motor too slow does more harm. They call it "lugging the motor": turning parts wear irregularly due to lack of speed/force.

I am wondering about minimum RPM for using loader and backhoe. Can you do harm by running too slow? What are recommended minimums? Rather not run my brand spanking new BX too hard for the first few hours. I have 1 hour on it! :cool2:

To be honest I never saw the point in running low RPM when using the FEL etc. during break-in, I ran it the same during that time as I do normally which is high enough to get good response. I am guessing it was generally around 2500 or so.

Thanks RRR and JT. I am new to this game and just want to learn as much as possible in a quick time before I do something stupid. I know stupid will come but just trying to put it off for awhile. :confused3:
