The TM51 Series Tandem Disk Harrow comes standard equipped with dual wheels for consistent disking depth. The dual wheels provide additional stability for even weight distribution during transport.

End washers help keep the gang shaft end nut tightened during operation, increasing gang wear life. Two gang nut wrenches are supplied with each unit and securely attached to the unit, ready to use when the gangs need tightening.

Hydraulic wing control on Frontier™ TM51 Series Tandem Disk Harrows shifts weight to the wings for better soil penetration and uses adjustable pressure to prevent gouging, while a relief feature protects the cylinders from damage.
