Recently purchased a new Kubota B2320 and it currently only has two hours on it. I've been removing snow in my driveway using the front end loader and have not had it past 2000 rpms nor have I really needed to. I was under the impression I should keep the rpms lower during this new "break in stage" but a friend tells me he runs his wide open or at least in the recommended range that shows on the instrumentation where one would run a pto driven implement. He says it wont hurt the machine and running a diesel motor at lesser rpms could cause problems because the diesel fuel wont burn correctly? Thoughts and opinions? :confused:

Well what I am doing and have done the m7040 is use it normally at what ever I'm doing . So it breaks in the way I will use it the rest of its life .

I have ran it low rpm and high rpm . Just depends on the job I have it doing .

I've always heard to break it in slow and easy because its fresh and new. I think somewhere on here there is an indepth posting on how to break in a tractor. I know the first 50hr service is crucial because you're getting out all the contaminants from being built in the factory, like any metal shavings and milling's that may be in the engine block from the factory.

Which to me is one potential reason to break it in gently at first, to make sure nothing is going to blow out the block.

The diesel engine will run and fuel will flow just fine even if you're putting around at idle.

My thoughts is like I said break it in how your going to use it then ya will never have a problem . Breaking in a motor slow and easy makes the motor think it going to have a slow easy life .

I'm not saying wind it all the way up all the the . Just use it normally .

Heck we break in all our 1 ton Diesels by hook a trailer to them and start pulling across county the way the will be used right off the lot . And ran them up to 500,000 miles and never had a problem .

But if ya Grandpa a motor then use it hard they want last . Because it was grandpa'd . Have seen that happen also .

Just use it normally and rpm it as the job needs and it will last for ever .

I just bought a new B3200 and I used the tractor for the first 50 hours ,according to what the manual stated.Not counting the first two hours before I read the manual that night Hey what normal guy reads the book then uses the product ? The tractor came off the flat bed , I doubled checked all fluid levels , and jumped on that baby pushing tree tops and smiling from ear to ear , knowing I would not be dragging brush anymore. Enjoy your new tractor.

I break mine in according to the manual which allows me to use it just as I do normally, PTO RPM is not quite full throttle and I run it at various RPM's with occasional cool down periods. I avoid long periods of the same RPM, but how I break them in is not much different than how I use one normally.

"Low RPM" is going to be different on a BX/B, L or M, I can work effectively at a much lower RPM on my M than BX, so "low" is relative.
