Wow, great forum! Thanx so much for the various comments. The question from mddorange was a good one.. Not only did the seller not have any data sheets or info, he only had one key! He was a decent fellow, and did caution me to change the oil, which I just did yesterday. But he did not even have the owners manual! I have been fortunate, in that a nearby Kubota dealer has some helpful folks, who have already emailed me the 94 page Operators Manual. The tractor has(had) 302 hours, and was in really nice shape.. No rust, no dents, gentle use it appears, hydraulics look good, everything works, etc. I was not planning to buy this big a tractor (was looking at a B2400 with front loader at the dealer, but everyone cautioned to "go a bit bigger than you think you need". Really glad I did this, as I cleared out the parking area at my farmhouse yesterday, using the loader, and it worked really well, but any smaller, and I dont think I could have done it. (This winter has been as crazy as last year - heavy packed 4-foot snow drifts everywhere... We get the same storm systems as Boston gets...) Been years since I drove a loader, but it came back to me ..
Thanx for the kind comments. I will post some pictures of the whole event, even the oil change, once I lift them from my phone.
The previous owner had at least changed the oil, and had the right filter. The L3400 (2011 year), uses an oilfilter from Kubota numbered "HH164-32430", and this filter was in the tractor. I used a Mobil "M1-204", as it was listed (and was) compatible. (The oil was black, so I felt I better change it before I did my first bit of work). Everything worked really well, and I was impressed with the power of the hydraulics. I'll post some pictures when I get chance.
