I looked at these and supposedly they can't lift much like my 800 pound wood working tools would be the max it would lift and then it would not be able to lift it very high.
I have the same L series Kubota, I move up to 1200lbs with regularity. Mostly it moves 350 gallon totes of split and stacked hardwoods around ( have acres that I collect the firewood off of, some of it, is up to a 1/2 mile of wood trails behind the house ).
Im guessing you looked at a (smaller ) BX model, to the untrained eye, all the Kubotas look alike, kinda. I think the L-series ( shown ) is rated at 1100 at 24" but Im working from memory ( not safe ).
Like everything, right tool for the right job, a tractor by design is not a really a good loader, but will function as one clearly. As an example, I didnt buy mine to move things around, I bought for a rototiller/brush hog/mower/trailer mover/box blade-gravel mover/firewood mover/pulling trees out of the back 40, its a utility tool, just happen to have purchased forks for it.
As it turns out, I use a root rake/grapple on the front of it more than anything else, that is I pickup and move tree canopies and brush to burn more than any other use. I use it to get the mail ( 1/2 mile haul to the mailbox ), stuff like that.
Problem with a tractor and forks, is maneuverability, just a like a full size skid loader, its worthless, due to size inside a building ( unless you have a 20k sqft shop ).
For maneuverability, I included a pic of what Im running now in the shop, the tractor brings it in the door, the Nissan takes it from there.
