Small Hay Rake/Hay Tedder/Rotary Hay Rake RXHR2500 for Collect Grass and Spread Hay

A rotary hay rake, also known as a hay tedder, is a piece of agricultural equipment used in the process of haymaking. Its primary function is to collect cut grass or hay from the field and spread it out in order to facilitate drying. The rotary hay rake consists of a set of rotating tines or arms that gather the hay into windrows or fluff it up to enhance the drying process.

The primary purpose of a rotary hay rake or hay tedder is to expedite the hay drying process. By spreading the hay out and fluffing it up, the equipment allows air to circulate through the hay more effectively. This not only speeds up drying time, reducing the risk of mold or spoilage but also ensures a more uniform drying process, which is crucial for maintaining the quality and nutritional value of the hay.

Key Components of Rotary Hay Rake(Hay Tedder)

The rotary hay rake, or hay tedder, comprises several key components that work together to efficiently spread and aerate hay for faster drying. Understanding these components is crucial for anyone operating or maintaining this piece of agricultural machinery. Here are the key components:

1. Tines or Teeth: These are the primary working parts that physically contact the hay, flipping and spreading it out. Tines are mounted on rotating arms or disks. Often made of flexible yet durable materials to withstand the rigors of contact with the ground and the hay.

2. Rotating Arms or Disks: These arms or disks hold the tines and rotate them through the hay. The rotation lifts and spreads the hay to expose it to air and sunlight. Their design varies with the model, including the number of arms or disks, which directly influences the tedder's efficiency and suitability for different hay volumes and types.

3. Gearbox: Transfers power from the tractor to the rotating arms or disks. It's essential for the precise control of the tedding operation. Must be robust to handle the torque and continuous operation, often requiring regular maintenance to ensure longevity.

4. Frame: Provides structural support for the tedder, holding all other components in place and connecting to the tractor. Typically constructed from high-strength steel to withstand the stresses of operation and the outdoor environment.

5. Wheels and Tires: Facilitate the movement of the tedder across the field. Their design impacts the ease of transport and the ability to navigate various terrains. Some models feature adjustable wheel positions to alter the tedding height and intensity.

6. PTO Shaft (Power Take-Off Shaft): Connects the tedder to the tractor's power take-off, transmitting mechanical power to the tedder. Often equipped with safety shields to prevent entanglement or injury.

Working Principle of the Tractor PTO Driven Rotary Hay Rake

A tractor PTO driven rotary hay rake works by transferring mechanical power from the tractor to the hay rake, enabling it to perform its function of spreading and aerating hay for quicker drying. Here’s a step-by-step explanation of how it operates:

Step 1: Power Transfer from the Tractor: The process begins when the tractor's PTO shaft is connected to the hay rake's PTO input shaft. The tractor's PTO is a splined drive shaft that provides a method for transferring power from the tractor's engine to auxiliary equipment like the hay rake.

Step 2: Activation of the Gearbox: Once the PTO shaft is engaged, the rotational power from the tractor's engine is transferred to the hay rake's gearbox. The gearbox is a crucial component that converts the engine's power into the necessary speed and torque to drive the rake's moving parts, primarily the rotating arms or disks equipped with tines.

Step 3: Rotation of Tines: The power transmitted to the gearbox causes the rotating arms or disks to turn. These arms or disks are outfitted with tines (or teeth) that physically interact with the hay. As the arms rotate, the tines lift, fluff, and spread the hay across the field. This action exposes more surface area of the hay to the sun and wind, significantly accelerating the drying process.

Step 4: Adjustment and Maneuverability: Operators can adjust several aspects of the hay rake for optimal performance, including the working width, tedding height, and intensity. These adjustments allow for efficient operation in varying conditions and with different types of forage. The hay rake is towed behind the tractor, and its wheels allow for smooth maneuverability across the field, enabling even coverage and effective tedding.

Choose the Right PTO Shaft for a Rotary Hay Rake

Choosing the right PTO shaft for a rotary hay rake involves considering several factors to ensure compatibility, safety, and efficiency. The PTO shaft is a crucial component that transfers power from the tractor to the hay rake, allowing it to operate. Here's a guide to help you select the appropriate PTO shaft:

1. Determine the Required Power Capacity: Check the power requirement of the hay rake (in horsepower) and ensure the PTO shaft can handle that level of power. The shaft must be capable of transmitting the required power from the tractor to the rake without overheating or failing.

2. Match the PTO Size: Tractors come with different PTO sizes, commonly measured in inches and by the number of splines (e.g., 540 RPM with a 6-spline shaft or 1000 RPM with a 21-spline shaft). Ensure the PTO shaft you choose matches the size and spline count of your tractor’s PTO output. Similarly, verify the input specifications of the hay rake's gearbox to ensure compatibility with the shaft.

3. Length of the Shaft: The length of the PTO shaft is critical for safe and effective operation. It should be long enough to connect the tractor and the rake without being under tension, but not so long as to risk entanglement or inefficiency. Measure the distance between the tractor’s PTO and the implement’s input shaft when hitched, keeping in mind that this distance will change as the tractor moves and turns. Many PTO shafts are telescopic, allowing for adjustment to the correct length. Ensure the shaft can be safely adjusted to fit the working distance between your tractor and the rake.

4. Safety Features: Choose a PTO shaft with reliable safety guards to protect operators and bystanders from entanglement hazards. These guards should cover the rotating shaft and be made from durable materials. Consider shafts with built-in torque limiters or shear bolts to prevent damage to the tractor or hay rake if the shaft encounters excessive resistance or if a jam occurs.

5. Maintenance and Compatibility: Look for a shaft that is easy to maintain, with readily available replacement parts. Regular maintenance is crucial for long-term reliability and safety. Ensure the shaft has high-quality universal joints and yokes for smooth operation and to accommodate the angles and motions involved in typical use.
