EARTH METAL DISK BLADES: Our industry-exclusive Earth Metal disk blades help you cover rocky terrain and uneven ground with confidence — even at high speeds. Equally tough and breakage-resistant in all directions, Earth Metal disk blades are proven stronger than ordinary carbon steel blades. Perfect for no-till and minimum-till environments, these disk blades penetrate hard, dry soils to help you break through surface compaction, effectively slicing through fall crop residue or spring weed flush.

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 Blade*- 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.

Durability and Low Maintenance For Any Field- The True-Tandem gang assembly precisely matches front and rear gang blades for maximum productivity and a smooth seedbed, regardless of field conditions. The 18-degree gang angle paired with the concavity and crimped center of each blade gives you even cutting and mixing action. With more durability and low maintenance features, the True-Tandem disk harrow will get you in and out of the field and ready to plant.

The U-shaped scraper design decreases the likelihood of bending when engaged with rocks and debris.

Extremely versatile from dry to wet conditions

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).

Nodular Cast-Iron Spools- Made from nodular iron, which is stronger than gray cast-iron or steel-fabricated spools

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.

Spools withstand shock loads, providing the weight necessary to cut residue and penetrate hard soil.

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

New Bolt-and-Clamp Mounting Design- Straight bolts and steel plates around the gang tube add strength and durability.

Reach Seedbed Perfection: Put the finishing touches on your seedbed with the double-edge TigerPaw Crumbler rolling reel. Every bar has two edges to hit large clods twice and tuck residue under the soil’s surface for improved leveling and better seed-to-soil contact. The unique design of the Crumbler ensures each bar is rifled to maintain constant down pressure, while hydraulic cylinders provide easy adjustability from the cab and settings to match any field condition.

TigerPaw Crumbler- The patented Crumbler produces more uniform clod sizing and residue distribution.

The formed, twisted, shape limits excessive penetration into the soil to minimize accumulation of mud inside the Crumbler.

The Crumbler is made of high-strength steel for a longer life.

Mounted directly to the main frame for a more stable, long-lasting and reliable tool.

Hydraulic Down Pressure- Hydraulic down pressure allows down-force to be applied to the Crumbler and easily adjusted to match field conditions

The force is changed with a hydraulic valve block found near the front of the tool.

3-bar Coil Tine Harrow-

Made to perform in high-residue conditions.

Adjustable tine angles and an adjustable down pressure.

Indexed tines improve soil leveling.

Hook to Your Tractor and Go:The rugged True-Tandem frame provides two height options for the hitch, depending on the tractor’s drawbar. Whether going across rugged, rolling terrains or field to field, you’ll be able to easily maneuver your equipment.

Front T-bone Hitch-

Spring cushioned, featuring the “perfect hitch” clevis for tractor pin compatibility and extra safety during hook up.

Engineered to maximize rear tractor tire clearance during tight turns.

Swivel Hose Stand-

Mounted on the pull hitch.

Keeps hydraulic hoses and wires out of the way during hook up and transport.

Rear Hitch Versatility-

Optional feature allows for pull-type attachments for additional soil conditioning.

Equipped with a 9-pin electronic connector for lighting and one set of hydraulic couplers.

Hitch vertical capacity is 1,000 lb.

Larger Tires, Less Compaction:Reduce compaction in your fields with large, stubble-resistant tires. Providing a greater footprint, these tandem wheels work independently for a smoother ride and longer life. With the rockshaft mounted directly to the frame, the hubs and tires are more durable and tillage tool more balanced.

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.
