Heavy duty leveling should be done with Three Point Hitch implements. A few Three Point Hitch levelers include: Land Plane Grading Scraper (LPGS), Box Blade and Rear/Angle Blades.
If your leveling work is moderate I suggest a Ratchet Rake bucket attachment, which will transfer abrasion from the bucket to the extended lower teeth on the Ratchet Rake.
Most used for tearing out brush, then piling the resulting debris, Ratchet Rake is also fine for moderate grading and small garden soil preparation.
You cannot DIG with a Ratchet Rake on the bucket.
Ratchet Rakes are sold by the T-B-N Store, button at top of this page. Delivery by UPS.

Tractors are prime movers. Now you need tools, which for tractors are called
implements when mounted on the Three Point Hitch and
attachments when mounted on the FEL.
Do not plan to pick up a heavy load with the FEL without ballast of some sort on your tractor, usually weight mounted on the Three Point Hitch. If you pick up a heavy load with the FEL without counterbalance, your rear wheels will lift in the air.
