I read online that a lot of people like the non-QA loader better.
FELs detach, but not very quickly nor conveniently. In seven years of tractor use, with three tractors, I have never removed the FEL. I have detached the bucket from the FEL many times, for improved forward visibility.
Did you intend to ask about QA bucket attachment to the FEL?. There are several proprietary QA bucket attachments out there. The INDUSTRY STANDARD QA bucket attachment is Skid Steer Quick Attach, (SSQA) which is seldom, if ever, criticized.
Are there different size R4 tires for each tractor or is there a standard size? I mean does the L3901 have several Industrial tire sizes to choose from or just one standard size?[/QUOTE]
Yes, dozens of sizes for different tractor weights.
