If you're not completely happy with your present equipment for incorporating chemicals or preparing smooth seedbeds on trashy surfaces or hilly ground, a rotary harrow that goes around in circles might be worth looking into.
"A key advantage of our harrow is that its rotating action levels the ground. It's great for incorporating chemicals and isn't affected by sidehills as are conventional harrows," explains Mark Thompson, of Strathmore Machine Works, Strathmore, Cal. "The sloping teeth release and spread trash, fertilizer, stalks, weeds, straw and other residues that clog ordinary harrows. These and other features have triggered new interest in a machine we've been making and selling in this area for many years."
The hitch on the harrow is designed so it produces a "twisting torque" when pulled. This slight torque is just enough to turn the round harrow counterclockwise as it's pulled forward.
"We can also build harrows that rotate clockwise," Thompson told FARM SHOW. "Farmers who use our round harrows in conjunction with tandem disks like to have them rotate clockwise rather than counter clockwise."
Models are available from 5 to 18 ft. dia. in 1-ft. increments. The 18-ft. model retails for $1,485, plus $615 for the hydraulically controlled wheel assembly. The wheels serve as adjustable depth gauges. Large 2-in. dia. bars divide the 18-ft. model into 12 pie-shaped sections. Individual spike teeth mounted on the bars are spaced 10 in. apart and at a slight angle. The 12-ft. dia. model sells for $636, not including wheels and hydraulic control assembly. Individual rotary harrows can be squadron
hitched for use with larger tractors, and can be used independently or in combination with other implements. When the teeth wear down, you simply cut them off, leaving a stub of about 11/z in, which is then used to anchor the new replacement tooth, explains Thompson.
