Greetings from Ontario, Canada. I just took delivery of a B7800 with the 402 fel and 63" Kubota rear mount snowblower and rear blade. I am looking for some advice on the break-in period for the tractor ( 1st 50 hrs?)The manual advises against running the engine at rated speed or running the tractor at a fast speed. We get a ton of snow around here (starting tonight in fact) and the tractor will have to work to get through the snow drifts. Also I get firewood from a woodlot a couple of miles from my place. What speed should I use for road travel during the break-in period? Do I have to go easy on the snowblowing during the break-in period. Any comments greatly appreciated.
Thanks,
Hank

When we break in the bigger tractors we run them for a couple of hours with increasing rpm and load progressing into foull throttle full load for about the last hour of a three to four hour run depending on if there is an hour or two of time on the unit or not. It is good to vary the throttle during break in. The snow blowing, just allow proper warm up time and you should be fine. We do like to see full load conditions but not for continious extended periods. Do not just expect from hour one to go full throttle and not let up on load or rpm. We do tell people as you get closer to ten hours just start using it the way you will run it. ....

Yikes I'd better check the forecast again. Maybe I should take the time to swap the box scraper for the blower.
I think the reason for instructions to maintain low ground speeds is that an engine shouldn't be lugged during its break-in. Lugging means a situation where the engine isn't capable of maintaining rpm given the load. An engine can be lugged from pto or hydraulic system use when the tractor is stationary as well.
A new engine may tend to run hot for awhile and running them hot during break in also doesn't do them any good. That's another reason to hold the speed down if it's going to be roaded during break-in. Art's description of use is what I understand as well and I think a consistent idea is don't baby them but keep an eye on the temp gauge.

I'm new here to the board, but I have learned a great deal before I purchased my new B-7800 with FEL, MMM & box scraper. Anyway I thought that it said in the book the usage break in period was 10 hours but for fluid and filter change it was 50 hours. I'll have to review the manual. I love this new machine. I do have a question about using a carry all on the 3 pt hitch. How much weight will this tractor pick up using a carry all? ....

Chances are the tractor will lift more than the carry-all is rated for.
Most carry-alls I have seen are limited to the 500-1000 pound range. If you need more lift than that you can get a set of three point pallet forks. ....

I know of at least one carry-all that is rated at 4000 lbs. With a beefy carry-all like that you would be limited by your 3ph lift capacity. ....

Forks are a trade-off. Heavy-duty ones weigh more and take their own weight off the 3ph capacity. My forklift weights over 600 lbs. It will lift huge weight with its but-plate on the ground. I can also move huge weight by abusing the tractor and putting everything heavy I can find in the loader and going slow on level ground--got to be aware of safety things though. A lighter forklift would be a better match for my tractor but I couldn't find one. ....
