    The Heavy Harrow is available in either a five-row configuration with 66-cm x 1.6-cm (26-in. x 5/8-in.) tines or a seven-row configuration with 66-cm x 1.3-cm (26-in. x 1/2-in.) tines. Both configurations have tungsten carbide Endura-Tip tines.

     

    • Easily replace tines by removing a few bolts and easily dropping out the tine bar.
    • Tine adjustment is simple with either mechanical or hydraulic adjust options.
    • The seven-row configuration offers approximately 68 percent more ground coverage in the field over the five-row configuration.
