So the rings are rated at 11,000lbs, giving 44,000lbs of securement.
If your straps are rated 10,000lbs each, and there are 4 of them you have 40,000lbs of securement.
Even considering the WLL of 3,335 for a 2" ratchet strap, you have 13,340lbs of securement. Right around three times the expected load.
For a tractor that weighs less than 4,500lbs.
I'd say you're good.
But.
You must provide securement for the implement. It has to be tied down independently of the tractor. A bucket requires a tiedown. A backhoe also requires securement. Even a bush hog or a mower, a rake or blade.
