Riding Mower Fitted With Front-Mount Dethatcher
The spring-toothed dethatcher mounts on a 5-ft. long pipe that attaches to an angle iron bracket on front of the mower deck. Johnson made the dethatcher by slipping a series of 8-in. long hay rake teeth over the pipe, and then bolting each set of tines to a length of 1 1/4-in. angle iron that's fastened to the top of the pipe. The 1 1/4-in. angle iron is bolted to a pair of 2-in. angle irons spaced 15 in. apart, which bolt onto flat metal brackets that bolt onto the deck.
He drilled a 7/16-in. dia. hole in each flat metal bracket and one 3/8-in. hole behind it in the deck itself, which accepts 2-in. long bolts.
The 7/16-in. bolts in the flat metal brackets were fitted with a washer and a stiff valve spring, and then were pushed down through the angle irons and brackets. "The 7/16-in. bolts need to be about 4 1/2 in. long," says Johnson. "The teeth will rise and fall as the deck goes up and down."
A pair of metal braces run back from the top of the pipe to the 7/16-in. bolts to provide reinforcement.
"It works great. Usually I keep the rake teeth flush with the bottom of the mower's tires," says Johnson.
