The bucket itself is similar in capacity. The most obvious difference is the "bent" arms vs. the "curved" arms. They say it makes the FEL easier to use by clearing up the view of the bucket. Sitting on a
BX2350, I don't disagree, but other than that, there is no functional difference between the new and old loader. One other nice thing is that the "kickstand" on the new loader is a one-motion affair...one piece with one pin. The old loader has a kickstand on each arm, so you have to deploy it on one side, walk around the tractor, then deploy it on the other side. Not that big of a deal, but unnecessary...the new loader definitely wins out on this one if those extra 10 seconds really matter to you.
I have a 3-way valve that comes off with the FEL. I have no other (or desire for any other) front implements, so it hasn't been an issue...preferable, really, to get that joystick out of the way when the FEL is not attached. But you can get a 4-way stick that stays with the tractor...you just need to order the right LA211 assembly to accomodate that "optional" setup vs. the "standard" 3-way valve. And, of course, order the 4-way assembly seperate from the LA211 FEL. Shouldn't be that big of a deal for your dealer.
I paid $2,400 for my loader 2.5 years ago. I'd expect it to be a few bucks more now, and I'd add another few hundred for the seperate 4-way control valve.
I'm sure somebody much smarter than me could fashion a QA setup so you could swap out the bucket quickly, but there is not one available from Kubota. Honestly, the capacity of the FEL is such that there isn't much else you could do with it, even if you had a QA. Couldn't lift a round bale with a spear...can attach forks to the bucket very easily already (BXpanded)...I'd just get some chain hooks welded on, is all.
And everyone says to get a toothbar...I don't have one and have been getting along just fine.
But then there's the grapple. Boy, I'd love to have a grapple. Ones are made for the BX FEL, but I haven't justified it yet.
