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.
NOTE: TMD5129 and TM5132 have 12 wheels total; six on the center section and three on each of the wing sections.
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 is standard equipment on all Frontier™ TM51 Series Tandem Disk Harrows. A control valve allows varying hydraulic pressure to the wing-fold cylinders. It transfers weight from the mainframe to the wings to improve penetration in hard ground and/or heavy soils. Increasing pressure to the rod end of the cylinder holds the wing level to prevent gouging in soft or moist soils.
The pressure relief feature allows wings to flex over obstacles to help prevent damage to the cylinder rod. Convenient knob adjustment can be easily reached from the front of the disk. The indicator gauge provides the operator with a quick visual indication of the results of the adjustment.
NOTE: Requires a tractor with closed-center hydraulics. Operators must follow special operating instructions per the operator's manual.
Oil-bath disk gang bearings with a standard wear plate allow consistent lubrication and prolong bearing life with minimal maintenance.
This feature ultimately saves both time and money.
The front gangs overlap, eliminating the need for a middle breaker.
This provides a more-level soil profile, ensuring complete coverage on each pass.
Safely transport the TM51 Series Tandem Disk Harrow from the farm to the field easily with the standard pintle hitch.
A two-blade taper, including the furrow filler on the outside rear wing, reduces outside ridges and smooths out the soil to create a level soil surface.
Transport locks secure the unit for transport mode.
Two separate control arms are standard, one for transport leveling and one for leveling while the disk is in the ground.
Once set for a given soil condition, the disk will continue to perform with consistency.
