Magnum Drawbar Harrow

Built to Perform, Built to Last

Great in the Field. The primary uses of the Gates Magnum Heavy Harrow are for heavy residue management, fertilizer and chemical incorporation, spring seedbed preparation, and post-seeding operations. Saves Time and Fuel. With the Gates Magnum Heavy Harrow, you can run at high speed (8-12 mph) covering large areas in less time.  With today’s high fuel prices, it can give you fuel savings of 50 to 75 percent over conventional implements. A Winning Combination! The combination of 5/8″ x 30″ or 9/16” x 26” tines, unsurpassed section down-pressure, a heavy tubing frame (10″ x 10″ x 1/4″wall HSS), and precise, hydraulic controlled tine angle adjustments make the Gates Magnum an ideal machine for all types of farming practices.
