The Toolcat tipping weight formal rating is 3,000 pounds. Even the A and B Toolcats lift and curl more than 1,500 lbs. at less than full lift height. But when you lift a ton with pallet forks, they're not good over 4 feet high while the C series should handle a ton to five feet high. My heaviest attachment, an Ammbusher hydraulic rotary cutter, weighs over 1100 pounds and can be moved around without strain.
And yes, SkyPup, the machine is great with grapples. I have a 63" hydraulic CID root rake brush grapple that tackles lots of brush and growth, or whatever you want to grab such as good-sized logs, etc.
