Having now had some experience with a tractor, you can't overstate the control you have on the FEL with the increased visibility of the Toolcat. You just cant' do any kind of delicate work with an FEL on a tractor.
The FEL is rated at 1,500 lbs at full height, but like others have said, it's designed to lift a pallet of sod off of a truck bed. I've lifted a one ton pallet of fertilizer without any problem. I like that I can do some heavy lifting without worrying about attaching counter weight on back. I can lift very little with the tractor unless I have a heavy implement mounted on the 3-PT hitch.
