Need help?Do you have a question about the New Holland 157 and is the answer not in the manual?
This document provides specifications for New Holland Tedders and Rake Tedders, agricultural implements designed for spreading (tedding) and raking hay to facilitate drying and collection. The manual details various models, including the 157, 163 (Manual Fold and Hydraulic Fold), H5270 Tedders, and the 255 Rake Tedder.
Tedders are primarily used to spread out cut hay evenly across a field, allowing for faster and more uniform drying. This process, known as tedding, helps aerate the hay, reducing moisture content and preventing spoilage before baling. The New Holland tedders offer different configurations to suit various farm sizes and operational needs.
Model 157 Tedder:
The Model 157 is a compact tedder, suitable for smaller operations or fields where maneuverability is key. Its 3-point attachment makes it easy to connect and disconnect from a tractor. The standard PTO slip clutch protects the driveline from sudden shocks, enhancing durability.
Model 163 Tedder (Manual Fold):
The Model 163 Manual Fold tedder offers a wider working width compared to the 157, increasing efficiency for larger areas. Its towed attachment design allows for greater flexibility in tractor compatibility. The manual folding mechanism requires manual intervention to switch between operating and transport configurations.
Model 163 Tedder (Hydraulic Fold):
The Hydraulic Fold version of the Model 163 provides the same wide working width as its manual counterpart but with enhanced convenience. The hydraulic folding feature allows operators to switch between working and transport positions from the tractor cab, saving time and effort. This requires one tractor remote valve for operation.
Model H5270 Tedder (Hydraulic Fold):
The H5270 is the largest tedder specified, designed for maximum productivity in extensive fields. With six rotors and a significantly wider operating and tedding width, it can cover large areas efficiently. Its hydraulic folding mechanism and robust tire configuration (including both center and outer tires) ensure stable operation and transport. This model also requires one tractor remote valve.
Rake tedders combine the functions of a tedder and a rake, offering versatility in hay management. They can be used to spread hay for drying (tedding) or to gather it into windrows for baling (raking). This dual functionality can reduce the need for multiple implements, saving on equipment costs and storage space.
Model 255 Rake Tedder:
The Model 255 Rake Tedder is a versatile implement capable of both tedding and raking. Its adjustable raking width allows for flexibility in creating windrows of different sizes. The use of double tines per arm enhances its effectiveness in both spreading and gathering hay. The 4-ply tires provide durability and stability in various field conditions. It requires a tractor with 30 hp and a 540 rpm PTO for optimal performance.
PTO Slip Clutch: All models feature a standard PTO slip clutch, which is a critical safety and maintenance component. It protects the tractor's PTO shaft and the implement's driveline from damage due to sudden overloads or blockages by allowing slippage when torque exceeds a certain limit. This helps prevent costly repairs and extends the lifespan of the equipment.
Tractor Attachment: Tedders are available with either 3-point or towed attachments. 3-point attachments (like on the Model 157) are typically for smaller implements, offering good maneuverability and easy lifting for headland turns. Towed attachments (on Models 163 and H5270) are common for larger implements, distributing weight over more wheels and often allowing for higher working speeds.
Tractor Remote Valves: Hydraulic fold models (163 Hydraulic Fold and H5270) require one tractor remote valve. This indicates that the tractor needs a hydraulic outlet to power the folding mechanism, providing convenience and efficiency for operators.
Safety Tow Chains: Standard on towed models, safety tow chains are crucial for preventing runaway implements in case of a hitch failure, ensuring safety during transport.
Tires: Various tire configurations are specified across the models, including 15 x 6 x 6 and a combination of 18 x 8.50 - 8 and 16 x 16.50 - 8 for the largest H5270 model. The 4-ply rating on the Model 255 Rake Tedder's tires indicates enhanced durability and load-carrying capacity, important for field operations. Proper tire inflation and maintenance are essential for stability, traction, and longevity.
Tractor Requirement: The specified PTO tractor requirements (ranging from 15 hp to 35 hp) and PTO speed (540 rpm for the Rake Tedder) are crucial for ensuring the implement operates efficiently and safely. Matching the implement to a tractor with adequate power prevents strain on both the tractor and the implement.
Design and Specifications: The document notes that "Design, materials and/or specifications are subject to change without notice and without liability therefor." This is a standard disclaimer indicating that manufacturers may update product designs and specifications over time. Users should always refer to the most current information available from New Holland.
Safety: A prominent "THINK SAFETY" message emphasizes the importance of understanding and following safety procedures. It advises operators to read the Operator's Manual, pay attention to safety and operating decals, and never operate machinery without all shields, protective devices, and structures in place. This highlights the manufacturer's commitment to operator safety and the need for responsible equipment operation.
Overall: The New Holland Tedders and Rake Tedders are designed to provide efficient and reliable solutions for hay management. With a range of models offering different working widths, folding mechanisms, and functionalities, farmers can choose the implement best suited to their specific needs, from small-scale operations to large commercial farms. Key features like standard PTO slip clutches, hydraulic folding options, and robust tire configurations contribute to the performance, durability, and ease of use of these agricultural machines. Regular maintenance, as outlined in the Operator's Manual, is essential to ensure the long-term performance and safety of these implements.
