Home-Built Wood “Dethatcher”
He made the 3-ft. wide by 2-ft. deep dethatcher by bolting together 2 by 6’s and 2 by 8’s, with one 2 by 8 on front and one on back. It attaches to the tractor with a pair of chains that hook onto a trailer hitch on the tractor.
He drilled a series of holes a couple inches apart into the front board, then hammered square concrete nails into them. The nails extend about 2 in. below the board.
“I make a pass with the dethatcher to loosen the soil. Then after I spread grass seed I make a second pass. The nails turn the soil over and bury the seeds, and the 2 by 8 on back smooths out the ground,” says Koch.
He says the nails he used run straight down and tend to plug up with grass. They’re also square, which eventually caused the board to crack. “I had to screw a 1 by 6 board over the crack to keep the nails from falling out. If I did it over, I’d use 3-in. round concrete nails and angle them backward so they’d break up the soil without picking up grass,” notes Koch.
