Looks like you already posted the first part of your question in another thread, where it was already answered. But with regard to the LB1914, it is almost exactly like the Kubota B8200 from the 1980's. They are very similar in looks (espcially the hood), horsepower (19), they both have manual transmissions with transmission driven PTO's. The Kioti LB1914 is a very old design that they kept alive because it's cheap to produce. There has been speculation for 5 years that it would be discontinued, but dealers still have them. You can buy a new LB1914 for $9600 with a loader.
/ looking at JD/Kubota/Kioti- which models compare?
If you are looking for a Kioti that compares to the JD2320 or Kubota 7610 range you would look at the CK20 or CK25. The CK20 would be less $$ than either and the CK25 about the same price as the JD or Kubota I believe. Both Kioti's are heavier (the CK25 much heavier) than either the JD or B7610. Generally people seem to think the B series Kubotas are optomized for mowing (lightweight for power) while the Kioti is optomized more for ground engaging and loader capacity. I suspect the JD would be in between but I don't know that model as well.
