The 24" Gator Rake Lute/Scarifier is a great tool for breaking up hard-pan, algae and fungus on Har-Tru clay courts. The 24" Gator Rake Lute/Scarifier utilizes the same durable, 1/8" thick stainless steel round tubular tines found on the Gator Rake. The tines are adjustable and can be replaced when needed.
