3 Point Hitch Disc Mower for Grass Cutting and Hay Cutting

[embed]https://youtu.be/3ApydHbW9hY[/embed] A 3-point hitch disc mower is a valuable piece of agricultural equipment designed for efficient grass and hay cutting in farming operations. Mounted to the three-point hitch of a tractor, this mower utilizes the power take-off (PTO) to drive its cutting action, making it an integral tool for forage and hay production. The 3-point hitch disc mower attaches directly to the three-point hitch on the rear of a tractor. This system provides stability and allows for easy lifting and lowering of the mower for operation and transport. It features several discs equipped with sharp, rotating blades. These discs cut the grass or hay as the tractor moves forward, offering a clean and efficient cut. The mower operates via the tractor's PTO, which powers the rotation of the cutting discs. This direct drive system ensures efficient energy transfer from the tractor to the mower. Operators can adjust the cutting height to suit the specific needs of the grass or hay being cut, allowing for flexibility in managing forage quality and ground conditions.

Working Principle of the 3 Point Hitch Disc Drum Mower

The 3-point hitch disc drum mower operates through a series of steps:

1. Mounting: The mower is attached to the tractor's three-point hitch, which consists of two lower arms and an upper link. The lower arms are connected to the mower frame, while the upper link provides vertical adjustment.
2. Power Source: The mower is powered by the tractor's power take-off (PTO), which transfers power from the tractor engine to the mower blades. The PTO shaft is connected to the mower's gearbox, which increases the rotational speed and transmits it to the cutting mechanism.
3. Cutting Mechanism: The cutting mechanism consists of a set of horizontally rotating disc drums equipped with cutting blades. These blades are mounted on the drums at specific intervals and are designed to cut the standing crop as the mower moves forward.
4. Height Adjustment: The mower's height can be adjusted using the upper link of the three-point hitch. By changing the angle of the upper link, the cutting height can be increased or decreased, allowing the operator to adapt to different crop conditions or cutting requirements.
5. Operation: Once the mower is properly attached and adjusted, the tractor moves forward, pulling the mower along. As the disc drums rotate, the cutting blades engage with the crop, slicing it at the desired height. The cut material is then discharged to the side or rear of the mower, forming a windrow or spreading it evenly, depending on the design of the mower.
6. Safety Features: To ensure safe operation, most disc drum mowers are equipped with various safety features. These may include guards around the rotating blades to prevent debris from being thrown out, shear bolts or slip clutches to protect the mower from damage in case of an obstacle, and a quick-release mechanism to disengage the mower from the tractor in emergencies.

3 Point Hitch Disc Mower Installation Operation

Installing a disc drum mower to a tractor generally involves the following steps:

• Position the Tractor: Park the tractor on a level surface and engage the parking brake to ensure stability during the installation process. Adjust the three-point hitch to the proper height. This can usually be done by using the hydraulic control lever or crank on the tractor. The hitch should be set to match the attachment points on the mower.
• Align the Mower: Position the disc drum mower behind the tractor, aligning the lower hitch arms of the mower with the attachment points on the tractor's three-point hitch. Ensure that the hitch arms are securely connected to the tractor.
• Attach the Top Link: Connect the top link of the three-point hitch to the upper attachment point on the mower. Adjust the length of the top link as needed to achieve the desired height and level the mower. Double-check all fasteners, including pins and bolts, to ensure they are tight and secure. This step is crucial for safety and to prevent any parts from becoming loose during operation.
• Connect PTO Shaft: Attach the power take-off (PTO) shaft of the mower to the PTO stub on the tractor. The PTO shaft should slide onto the stub and be secured using the locking mechanism, such as a collar or a pin.
• Adjust Height and Level: Use the tractor's hydraulic control lever or crank to adjust the height of the mower. Set it to the desired cutting height, keeping in mind the type of crop and cutting conditions.
• Test Operation: Before starting the actual cutting, engage the PTO and observe the mower's operation. Ensure that the blades rotate smoothly and that there are no unusual vibrations or noises. Check for any interference between the mower and the tractor.

Proper Maintenance of the 3 Point Hitch Disc Mower

Proper maintenance of a 3-point hitch disc drum mower is essential to ensure its optimal performance, extend its lifespan, and promote safe operation. Here are some maintenance tasks to consider:

1. Regular Cleaning: After each use, clean the mower thoroughly to remove any debris, grass clippings, and other material that may have accumulated. Pay attention to the cutting blades, disc drums, and discharge chute. Use a brush or compressed air to remove stubborn debris.
2. Blade Inspection and Sharpening: Regularly inspect the cutting blades for signs of wear, damage, or dullness. Replace any blades that are bent, cracked, or excessively worn. Sharpen the blades as needed to maintain their cutting efficiency. Follow the manufacturer's recommendations for blade maintenance and sharpening techniques.
3. Lubrication: Keep all moving parts properly lubricated according to the manufacturer's instructions. This includes lubricating bearings, gearbox components, and any other areas specified in the maintenance manual. Use the recommended lubricants and follow the recommended intervals for lubrication.
4. Gearbox Inspection: Check the gearbox for any leaks, abnormal noises, or signs of wear. If you notice any issues, address them promptly to prevent further damage. Follow the manufacturer's guidelines for gearbox maintenance and lubrication.
5. PTO Shaft Maintenance: Inspect the PTO shaft for any signs of wear, damage, or loose components. Ensure that the protective shielding is intact and properly secured. Grease the PTO shaft as recommended by the manufacturer.
6. Check Nuts and Bolts: Regularly inspect all nuts, bolts, and fasteners on the mower for tightness. Vibrations during operation can cause them to loosen over time. Tighten any loose fasteners to ensure the mower remains properly assembled.
