Tractor is 2800, the FEl is about 1000 to 1200 with the mounts and bucket. IF the tires are filled that adds about 400-500 more pounds per tire depending on size and fill material. Firestone's web site has weight specs on filled tires. If you put a heavy implement on it, you will be close to over weight for a 7k trailer. You only get to haul about 5000 pounds net weight as the trailer is about 2000 pounds. If it's a one time shot to get the tractor...well it's up to you. Don't forget to chain it down good. I go thru the big hole in the loader and thru the rear wheels. Use a ratcheting binder, not the snap over ones. Around here the troopers will stop you if you don't use DOT transport chains.
