Tomorrow? Congrats, it's gonna be a long 24hrs
re. what to look for. The dealer should have it prepped up and real shiney so any leaks, dings, cracks etc should be real evident. Not that there will be any but if there are you should see it when you're testing it out.
The dealer should show you how to properly hook everything up and also how to operate it. IIRC they should also go over the warranty with you too.
I would recommend to check the front axle oil level as theres been many posts about it being low. This is supposed to be part of the dealer prep but it seems to fall inbetween the cracks on some. Check the engine oil level and the HST oil level also and if any are low make sure they provide you enough fluid to bring them up to spec free, as thats part of the prep.
Also ask if they had greased the MMM's zirks as some have reported that the 1st time they greased their MMM's that it took quite a bit of grease before they saw that they were full. Engine oil and HST oil should be checked too.
Make sure everything works while they're there and ou should be GTG.
re. scheduled maintenance. The 50 is your 1st, then the 100 hr then @ 100 increments from that point on. I adhered to the schedule (still do) and try to follow it to the "T". IF you do that you'll be good w/any warranty work should that need arrises.
Some didn't wait on the 50 hr mark and did theirs early and some others waited past the 50 hr mark. Again follow the manual and you'll be GTG.
re. breakin. The manual spec's to not run @ WOT for the 1sr 50 hrs and to vary the rpm when working it. I purchased my BX23 in the dead of winter and when mowing season arrived I had already met the 50 spec and went right at it. I pretty much adhered to the 50hr requirement and kept under WOT (no tach on the BX23) and varied the rpm every 10 - 15 minutes of run time for a sec to two then went back up to the rpm I was working @. This gives the cylinder a good backwash of oil and helps clean it of any ring/cylinder wear debris.
With all that said, theres been some that ran their new BX's like they intended to work 'em and went WOT right off the bat and reported no problems with it. They argued there wasn't any breakin requirement on new cars/trucks so they felt the BX should be fine also. I do know that Harley Davidson required a 500 mile breakin and I adhered to it when I did purchase one new.
In anycase, you'll probably be fine to work it hard from the get-go as long as you back off every now and then to give it a good backwash but since I followed the 50 hr breakin spec, thats what I recommend to you too.
The owners manual is actually pretty good and should give you some good reading. The implement manual(s) are good too. SO make sure you get a manual w/all the implements. There will be a few translation gafs but all in all the manual(s) are very good.
It specs out all the required maintenance and has drawings to help you out.
Kubota changed the required manitenance specs from my model to the new models in that the HST fluid isn't spec'ed to be changed at the 50 hr now which saves you some $$$'s. I believe it's not required until the 300hr now. Mine was spec'ed at the 50 and then again @ the 300 and every 300 after that. Theres been many the debate over that change and some have even contacted Kubota wanting verification that the manual was correct and the response has always been the same, FOLLOW THE MANUAL!
So while you lay awake tonight with visions of an orange tractor dancing in your head. make sure you RTM (read the manual) and you should be GTG. Course we're all here ready to help and share the excitement
