Vertical Feed Mixer Gearbox Maintenance Tips

Understanding the Vertical Feed Mixer Gearbox

The vertical feed mixer gearbox is a crucial part in agricultural machinery. It is essential for the mixing and processing of animal feed in a vertical feed mixer, making it an indispensable tool in modern farming. This gearbox takes power from the tractor's PTO (Power Take Off) and uses it to drive the mixer's auger or paddle, effectively mixing the feed.

Advantages of the Vertical Feed Mixer Gearbox

• Increased Efficiency: The vertical feed mixer gearbox helps to improve the efficiency of the feed mixing process.



• Greater Power Conversion: It converts the high-speed, low-torque power from the tractor's PTO into a lower speed, high-torque motion needed for mixing.
• Robust Design: The gearbox is designed to withstand the harsh conditions of agricultural work, ensuring its longevity.
• Easy Maintenance: With proper maintenance, the gearbox can function optimally for a long period.
• Versatility: It can be fitted onto different types of tractors and feed mixers, making it a versatile choice for farmers.

At XinLan, we specialize in producing these gearboxes, providing a perfect replacement for damaged parts on your agricultural machinery.

Applications of the Vertical Feed Mixer Gearbox

• Animal Feed Production: The gearbox is used for mixing different types of animal feed.
• Poultry Farming: It is used in poultry farms for mixing poultry feed.
• Dairy Farming: Dairy farmers use it for preparing feed for their livestock.
• Aquaculture: The gearbox is also used in aquaculture for preparing fish feed.
• Specialty Farming: It is used in specialty farming operations such as horse breeding and rabbit farming.

How Does the Tractor PTO Driven Vertical Feed Mixer Gearbox Work?

• Tractor PTO: The PTO is a splined driveshaft, usually located at the rear of the tractor, that provides power to the attached implement. In this case, it powers the vertical feed mixer.
• Gearbox: The gearbox is the component that receives the rotational power from the tractor's PTO. It converts this power into the required form and speed to drive the mixer's auger(s) or paddle(s).
• Vertical Augers or Paddles: These are the components within the mixer that physically mix the feed. They rotate vertically, lifting feed from the bottom of the mixing chamber and then letting it fall back down, creating a thorough mixing action.
• Power Transmission: When the tractor's engine is running, power is transmitted through the PTO 轴 to the gearbox of the vertical feed mixer.
• Speed Conversion and Torque Amplification: The gearbox converts the high-speed, low-torque rotation from the tractor's PTO into a lower speed but higher torque motion needed to drive the mixer's augers or paddles. This process involves using gears of different sizes within the gearbox to adjust the rotational speed and torque according to the requirements of the mixing process.
• Mixing Process: The converted power activates the vertical augers or paddles, which rotate to mix the feed. The rotation moves the feed upwards against the sides of the mixing chamber and then allows it to fall back down into the center, ensuring a uniform mix.

Tractor PTO Driven Vertical Feed Mixer Gearbox Installation Steps

1. Read the Manual: Before starting, thoroughly read the gearbox and feed mixer manuals for any specific installation instructions or precautions. Check the new gearbox and the mixer for any shipping damage and ensure you have all necessary parts and tools for the installation.
2. Mounting the Gearbox: Align the gearbox with the mounting points on the feed mixer. Use the bolts provided to secure the gearbox to the mixer. Ensure that all bolts are tightened to the recommended torque specifications to avoid any movement or vibration during operation.
3. Attaching the PTO Shaft: Connect the PTO shaft to the tractor and gearbox, ensuring that the locking pins are properly engaged. Check that the shaft can rotate freely and that there is enough clearance for turning and tilting without interference.
4. Connecting Hydraulic Lines (If Applicable): For gearboxes or mixers that use hydraulic systems for functions like discharge doors or additional auger controls, connect the hydraulic lines from the mixer to the tractor's hydraulic outlets. After connecting, start the tractor and operate the hydraulic functions to check for any leaks at the connection points.
5. Testing: With the tractor in a stationary position, start the engine and engage the PTO at a low speed. Observe the mixer operation, listening for any unusual noises or vibrations that could indicate an issue with the installation. Increase the PTO speed to the operating speed recommended by the manufacturer and check the mixer operation under load.

Common Troubleshooting of the Vertical Feed Mixer Gearbox

• Gearbox Makes Unusual Noises: This could be due to worn or damaged gears, insufficient lubrication, or foreign objects in the gearbox. Inspect gears for wear or damage and replace them if necessary. Ensure the gearbox is properly lubricated according to the manufacturer's instructions. Check for and remove any foreign objects.
• Gearbox Overheating: Causes could include overloading the mixer, running the mixer for too long without a break, insufficient lubrication, or damaged bearings. Avoid overloading the mixer beyond its capacity. Allow the mixer to rest if it has been running for extended periods. Check and replenish the gearbox lubricant. Inspect bearings for damage and replace if needed.
• Gearbox Leaks Oil: This could be due to worn or damaged seals, loose bolts or fittings, or a crack in the gearbox housing. Replace worn or damaged seals. Tighten any loose bolts or fittings. If there is a crack in the housing, it may require welding or replacing the gearbox.
• Mixer Does Not Operate at Full Capacity or Speed: This could be due to the gearbox not properly engaging, PTO shaft issues, or internal gearbox damage. Ensure the gearbox is fully engaged and the PTO shaft is correctly connected and functioning. Inspect the internal components of the gearbox for damage and repair or replace as necessary.
• Difficulties in Shifting Gears: This could be due to lack of lubrication, worn internal components, or misalignment. Lubricate the gearbox thoroughly. Check for worn gears or shafts and replace them if necessary. Ensure the gearbox is properly aligned with the mixer and PTO shaft.
• Increased Vibration During Operation: This could be due to an imbalance in the mixing augers, damaged gearbox bearings, or loose mounting bolts. Check the mixing augers for proper balance and adjust or repair as needed. Inspect and replace damaged bearings. Secure all mounting bolts to reduce vibration.

Agricultural PTO Shaft for Vertical Feed Mixer Gearbox

• Shaft type: The PTO shaft for agricultural applications is typically a splined driveshaft. It consists of an inner male spline and an outer female spline that engage with the corresponding splines on the tractor's PTO output shaft and the input shaft of the gearbox.
• Length and size: The length of the PTO shaft depends on the distance between the tractor's PTO output shaft and the input shaft of the vertical feed mixer gearbox. Additionally, the size of the PTO shaft (diameter) should be suitable for the power requirements of the vertical feed mixer gearbox.
• Safety features: PTO shafts are equipped with safety features to prevent accidents and injuries. One common safety feature is the use of a telescoping or sliding mechanism that allows the shaft to collapse or extend as needed.
• Guards and shields: PTO shafts are typically equipped with guards and shields to protect operators and bystanders from coming into contact with the rotating shaft.
• Maintenance and lubrication: Regular maintenance of the PTO shaft is essential for optimal performance. This includes inspecting the shaft for wear, damage, or loose components, as well as lubricating the shaft according to the manufacturer's recommendations.
