I am from Australia, as a lot of you probably Australian design rule (ADR as we know it) require that all FEL's are self leveling. (All legal (nanny state) arguments aside, that is an argument for another thread.)
The self leveling loader is great particularly with a set of forks, the forks always stay parallel to the ground, nothing comes of the back of the load. The bucket can also be smaller and lighter yet carry the same load because there is no requirement for a spill guard.
That brings me to 4 in 1 buckets. I do not know what I would do with out mine they are so versatile, picking things up, using it as a grader blade, scraping etc.
Most new tractors sold in my area are fitted with 4 in 1 buckets, there are 4, 1023E sitting at the local dealers all fitted with aftermarket FEL's and 4 in 1 buckets. You can order JD FEL's if you want.
When I went looking to buy my 1025R I was not interested in the JD FEL because of it's complicated self leveling systen but mainly because it didn't come with a 4 in 1 bucket.
My question is why I have yet to see a posting of a SCUT with either a 4 in 1 bucket or self leveling FEL and why arn't they popular in the U.S.?
PS Attached is a photo of my 1025R as you can see I like to get it dirty
