My first question as a B7800 owner - break in

mkflyfish · Apr 4, 2003

I know this is more like owning and operating, but to me it applies to anyone purchasing a tractor, so I posted here.

OK, the only thing I see in the manual is to not operate the Tractor at Full Speed for the First 50 Hours....

What does this mean? Not to run the motor at 2600 rpm ? Or don't go work on my wife's riding arena with the box blade (I desperately need to do this so that I can totally justify my new Orange ride) ?

Maybe I'll just putz around the yard for the next 49.2 hrs straight.

Michael, this topic has been discussed at some length in the past but I don't know that I could find the old threads. Yes, the manual says to not operate it at full speed or full throttle the first 50 hours, but PTO speed is a couple of hundred rpm below that. /forums/images/graemlins/wink.gif You might ask your dealer what he thinks, but I think the concensus of opinion is to not worry about it; just go on to work with it, but vary your rpm occasionally; i.e., I probably would not set out to run it at PTO speed for the first 8 hours without a break or slowing down. Basically, just break it in the way you intend to use it, and too slow rpm is almost undoubtedly worse than too fast, in my opinion.

Perhaps I could help!

Bring it up here to Nova Scotia and I'll do the break in for you. I can even wear some of the paint of the bucket so it will look like a real tractor.
Just keep varying the RPM's for the first little while and really load it up for a few minutes on the odd occasion.

I'd even go so far as to change oil and filter after 10 or so hours.

HI,

I forget exactly what I did, but I know I limited my rpms to some extent and gradually increased them.

I was doing a lot of backhoe/loader work when I got my B2910 last summer. I kept increasing max rpm every ten hours. Starting at about 15 or 1600 rpm, that gave me max rpm at 100 hours.

And since I was learning how to operate the backhoe, this was probably wise anyway, as at higher rpms the backhoe moves faster.

Many feel running at different rpms during breakin is best. I can't say I feel any different...

Have fun with that new tractor! You will get a lot of work done you otherwise would not have. That is for sure!

"Full speed" is full throttle. That isn't the same as correct PTO RPM or proper implement operating speed - it is when the engine governor kicks in. My wife seems to love shoving the throttle all the way to "rabbit". Drives me nuts (I don't think it is good for the tractor regardless of the number of hours), but she likes the extra power she thinks she gets.

No, she doesn't use implements much - I'd hate to see how fast the backhoe would fly at max RPM /forums/images/graemlins/ooo.gif.
