Single-point Hydraulic Depth Control

• Easily adjust operating depth with a single hand crank conveniently located at the front of the machine
• Helps adjust to adverse conditions, such as wet, muddy soil
• The system holds a constant blade operating depth to provide a uniform seedbed depth temperature, contributing to early, even plant emergence

Fore and Aft Leveling

• Optional hydraulic front-to-back leveling allows quick operator reaction to changes in field conditions
• View the gauge from the cab to easily return to your pre-adjusted position

Right-sized for Performance

• True-Tandem 345 disk harrow blades are 22 inches in diameter, right sized to handle residue and create the perfect seedbed
• The True-Tandem 375 all-purpose disk features a unique shallow concavity bladed front gang and a standard concavity rear gang that allow for better soil penetration and increased ground speeds of up to 7 mph. Standard concavity equipped front gang is also available for a more traditional disk configuration.
• A 26-inch blade option is available on the True-Tandem 375 disk harrow for maximum soil movement and mixing
• Blades provide additional tillage depth — up to 4 inches deep in one pass — to help move more soil and residue
• Capable of running 4.5-7 miles per hour for optimal performance and greater productivity

Built for Longevity

• Using pure boron alloy steel and an extremely precise manufacturing process means the disk blades hold their shape better and resist breaking or bending
• Each disk blade runs on its edge, causing soil to explode off the blade and level with minimal backside pressure — this results in reduced compaction compared with conventional blades

Crimped-center Disk Blades

• Blades feature a unique, flat, crimped center for a tighter fit with the cast iron nodular spools
• Blade design adds strength where it counts — in the center of the blade
• Disk blade scrapers are adjustable in gangs or individually
• Scraper arm options can be tailored to local conditions, with heavy-duty, rigid arm scrapers recommended for heavy soils and lighter residue situations

Rollable Disk Blades

A rollable disk blade offering allows customers who desire the ability to edge roll the disk blade to sharpen. Made of a high-quality alloy with the toughness and durability of boron while maintaining the ability to roll the edge. Note: This offering is not Earth Metal.

Bearing Options

• Flange-style bearing works well in fields with few rocks and debris
• For areas with rocks and debris, the cushion gang option holds the arbor bolt firm, yet allows the joint to rotate freely through rough terrain for a high-quality finish
• For extreme soil conditions and rocky areas, additional heavy-duty bearings and gang hangers strengthen and support longer gang segments (31 ft. and 34 ft. only)

Proven Center Shank Design

• A center shank removes the uncut soil between disk gangs to create uniform residue and soil mixing
• Designed to let residue and soil roll off

Nodular Cast-iron Spools

• Made from nodular iron, which is stronger than gray cast-iron or steel-fabricated spools
• Spools withstand shock loads, providing the weight necessary to cut residue and penetrate hard soil
• The needed weight to penetrate hard ground and cut residue is carried in the gang, not the frame of the tool to reduce the stress on frames, bearings and gang hangers

New Bolt-and-Clamp Mounting Design

• Straight bolts and steel plates around the gang tube add strength and durability

Frame-mounted Gauge Wheels

• Bolted directly to the frame, these wheels feature an adjustable, one-way pivot design, providing stability and less wobble in normal field conditions
• Design avoids sliding the gauge wheel and gouging the gang when wheel is on inside of turn
• Set the gauge wheel for easy wing leveling — no wrenches are needed
• Pivoting gauge radial stabilizer wheel increases surface area and provides improved durability

Walking Tandems

• Provide excellent depth control and stability
• Low-cost standard configuration or optional larger, stubble-resistant tires
