The loader can probably lift 1,150 lbs. but the tractor cannot except in IDEAL conditions.Here's the Kubota answer "The loader lift capacity is around 1,150 lbs, and therefore you won***8217;t notice the extra 100lb addition.
Also, the versatility of the 4-in-1 bucket is worth the extra 100 lbs"
FWIW, my L6060 is considerably larger and heavier than a 3901, the FEL lift capacity is more and, no doubt, my Kubota 4-in-1 bucket (the one compatible with the L6060) is heavier than yours.
I find the FEL/4-in-1 bucket combination to be almost useless without the sand filled ballast box on the three point. Indeed the tractor will not back up a small incline even with nothing in the bucket unless in FWA and even on a crushed rock driveway. Moreover, it is dangerous on inclines, again with nothing in the bucket. More than once, I have lifted the outside rear wheel when turning down minor inclines with nothing in the bucket. As a result, I always travel with the bucket near the ground to prevent excessive tipping before I can react by lowering the FEL. I also keep it in FWA when the FEL/bucket is attached to prevent quickly sliding down any incline that I might find myself on.
Caveat: I change and repair my own tires and have no provision for handling liquid ballast so do not use such. The 6060 does have two cast iron weights on each side and I do have the previously mentioned ballast box filled with unopened bags of playground sand that I can use with both the 6060 and my M9960.
Caution is advised.
