How long is the break in period for a 3030?

As I mentioned, and most all farmers and professionals I know feel the same way, if it isn't ready to work when I buy it; I don't need it. Good luck and be safe!

Sorry, I changed topics . I am not talking about break-in period. But operating the tractor after that. The question is why Diesel boat engines are recommended to run at 80% of Max RPM, but apparently not tractors?

The manuals I have had with them are very similar to the manual I have with my JD and CNH equipment; it says (and I quote from the manual) "The engine is ready for normal operation. Avoid unnecessary engine idling, watch for fluid leaks and check levels frequently". Other than that, the manuals basically instruct the operator to operate the machine as normal but to be sure to check bolt tightness and to be sure to do the 50 hour maintenance as directed. To be blunt, I would never buy a new piece of equipment that was not ready to work. Time is money and these companies know that fact.

Im confused? WHERE does it say anywhere in your post to run the engine at MAX RPM?

One thing I HATE about Kubota's ( and they all might be this way..??..I have no idea) is that the specs will state that the engine produces "X" horpower at "YYYY" RPM..and nothing more. No torque curve..no other engine data

Longevity!

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.

Same on the B2920. Max throttle gives you 2800 RPM, which is also PTO at 540.

The B2920 has similar language. So I'm not support to use my tiller or mow for 50 hours? Yeah, right. Even the dealer told me to use it as I please and there is no need to baby it.

Maybe I'm too impatient. Like I said earlier, I do not own a 3030 or even a 2920, but I do have two mowers with 28 hp 3 cyl Kubota engines in them. Both have been run at full throttle since the day I bought them new. The older one just passed 1600 hours last week and it still runs like new. But, hey, if it makes a guy feel better, more power to them. I keep complete logs on my maintenance and never miss any recommended item on the maintenance of the engines or transmissions. Other than that, I bought the machines to work and work is what they do. If I only get 10 or 15k hours on my engine rather than 17k hours on it before it's in need of a rebuild, so be it. As always, be have fun and be careful!

Thusly my point! If a guy NEEDS it...then WFO is the only speed. If ya dont...then WOT isnt a "have to do" sort of thing
