I ended up getting a new (still in crate)
L5740 with R4s, FEL, 2nd front hydraulic for future grapple and +/- snow blade. Paid $1K or so more than I thought market should be, but there aren't many left. I liked the smaller cab of the 5740 and the only thing I liked better on the 6060 was the loader control. The JD 4720 was probably too tall for my barn, as it has "regular' garage doors. I liked it OK, but I guess I'm just used to Kubotas. The JD pricing was very aggressive, but I liked the Kubota better overall. I have woods and the extra height of the JD would have been a minus.
Thanks for the info! Keeping my
L4300 for now...
