As is well known, farming is first and foremost a profession, and every important decision you make will affect your ultimate benefits. Therefore, in terms of soil management, which is crucial for farming affairs, the Case IH double row disc rake is definitely a wise choice. This series of disc harrows will help you maximize efficiency and overall performance, enabling you to achieve both profitability and soil cultivation success.
The advantages of true dual row linkage
By using Case IH once on farmland, the true advantages of dual row linkage will be fully demonstrated. The rake groups on both sides of the switch center work perfectly together to evenly distribute the traction force. With less field adjustment, higher stability can be achieved, and traction can be carried out more straightforwardly and easily. Unlike the "double offset" design of many competing products, the "true" double row linkage design of Case IH (as shown in the left figure) allows the rake blades in the rear rake group to move straight between the notches in the front rake group, achieving true full width cutting without leaving any uncut gaps. The differences between the two are obvious - appropriate residue size, thorough soil mixing, and more effective incorporation of chemical agents into the soil. Whether you choose rigid frame equipment or flexible wing frame equipment, every Case IH double row disc rake has these advantages.
The reaction force generated by the symmetrical rake group can offset the offset, and the rear rake group will cut the incision of the front rake group, so as to achieve uniform soil cultivation throughout the width range of the tool.
All models of double row disc harrows are equipped with industry-leading specialized Case IH Earth Metal ® Rake blades can provide extraordinary durability and crack resistance. It has been confirmed that Earth Metal harrows can effectively function in the field, with a strength 30% higher than traditional harrows and a service life of up to 20% under the same conditions. With its special shallow concave design, this unique rake blade is easier to pull than conical or spherical rakes, thus saving more fuel. It is these outstanding advantages that make the Case IH double row disc rake stand out.
Better design is only for preparing better planting beds
Case IH True Tandem 340 bed disc harrow is a new high-performance seed bed preparation system that can better cut and mix crop residues, form more regular soil block sizes, better penetrate crust hard soils, and provide better "out the back" ™ Performance. From this, it can be seen that this is not an ordinary double row disc rake. The True Tandem 340 takes seed bed preparation to a whole new level, helping you achieve higher production potential.
Carefully designed, with richer functions
Upon closer inspection of the True Tandem 340, you will discover various reasons why this disc rake provides outstanding performance. You can see at a glance that it adopts a heavier and stronger main beam frame. This main beam frame is reinforced by multiple 13mm thick crossbeams and fully integrated with the wing frame. This improved beam structure can increase soil permeability and ensure a longer service life. For models of 7.6 m and larger, 152 x 152 mm steel pipes are used for support to increase strength and weight.
From beginning to end, with ease and ease
When you are ready to attach the True Tandem 340, you can experience various functions that make the entire process safer and easier: the spring buffered self leveling front attachment device with a "perfect attachment" switch center is fully compatible with the horseshoe tractor towing hook. The popular spiral hose bracket can be used to secure hydraulic hoses and wires, preventing them from becoming obstacles. The True Tandem 340 can be adjusted to the height of the tractor towing hook using a screw buckle or an optional hydraulic leveling cylinder, allowing for quick leveling from front to back.
Design a multifunctional disc rake for dealing with multiple residues and dryland operations
The harsher the conditions, the more sturdy the disc rake you need to use. The newly launched heavy-duty True Tandem 370 multifunctional double row disc rake has been improved to provide better penetration and higher "out the back" performance ™ Performance. The beam frame used in True Tandem 370 is even stronger and more durable than 340, and has many of the same yield increasing functions, making it particularly suitable for dryland and multi residue management situations. For a strong person like 370, even the harsh soil and residue conditions are not a problem.
