Auto Lubrication System for Agricultural Sprayers

I. Industry Background of Auto Lubrication Systems for Agricultural Sprayers

With the advancement of agricultural modernization, large boom-type agricultural sprayers (including self-propelled and towed models) are widely used in large-scale field operations. The long boom length, frequent operation, and complex powertrain systems make lubrication maintenance a key factor affecting equipment lifespan and operational efficiency.

Traditional manual lubrication methods face the following issues:

1、Lubrication points are scattered, making comprehensive coverage difficult with manual maintenance.

2、Under high-frequency operation, lubrication omissions or over-lubrication are common.

3、Long-term exposure to pesticides, water mist, and dust leads to corrosion and wear of metal components.

Therefore, auto lubrication systems have become a standard configuration for medium and large sprayers. They not only significantly extend the lifespan of key components but also reduce maintenance costs and improve operational efficiency.

II. Lubrication Points and Quantity on Agricultural Sprayers

1. Boom System

The boom system is the most critical lubrication area on an agricultural sprayer, including:

①Boom folding hinge pins

②Boom lift mechanism pivot shafts

③Boom balance suspension hinge points

④Anti-sway mechanism link pivot shafts

⑤Central oscillation bracket bearings

Boom-related lubrication points typically account for over 50% of the total lubrication points on the machine, making them the core focus of the auto lubrication system.

2. Chassis and Undercarriage

①Front and rear wheel hub bearings

②Steering knuckle kingpins

③Suspension or oscillating axle hinge points

Tow hitch connection pivot shaft

3. Drivetrain and Connection Points

①PTO universal joint cross shafts

②Pump drive coupling bearings

③Belt tensioner pulley bearings (if equipped)

4. Lubrication Point Quantity

Sprayer Type Number of Lubrication Points

①Medium Towed Sprayer：15–25 points

②Large Boom Sprayer： 25–35 points

③Self-Propelled Sprayer： 30–40 points

Auto lubrication systems can cover all lubrication points, avoiding omissions inherent in manual maintenance.

III. CISOLUBE Auto Lubrication System Solution for Agricultural Sprayers

1. Recommended Lubrication Pumps

GT Auto Lubrication Pump: Suitable for medium and large sprayers, supports timed and metered grease delivery, stable and reliable.

GP203 Auto Lubrication Pump: Compact size, ideal for centralized lubrication of boom systems, fits space-constrained locations.

2. Distributor Configuration

DSP Main Distributor: Responsible for main line distribution, precisely allocating grease to each branch line.

DSPP Sub-Distributor: Used for zoning lubrication of left/right or front/rear boom sections, shortens grease lines, improves system response speed.

DSP / DSPP Material Selection: Carbon steel for standard conditions; stainless steel for high-humidity, pesticide-corrosive environments—higher cost but offers optimal corrosion resistance.

3. System Advantages

①Extends the lifespan of boom hinges and bearings

②Prevents manual lubrication omissions or over-lubrication

③Reduces manual maintenance labor costs

④Enhances long-term operational reliability of equipment

Improves operational efficiency and reduces downtime risk

IV. Practical Application of Auto Lubrication Systems on Agricultural Sprayers

Auto lubrication systems enable centralized control and metered grease delivery for multiple lubrication points such as boom folding, lifting, oscillation hinges, chassis steering, and drivetrain components. For large self-propelled sprayers, the system can simultaneously manage 30–40 lubrication points, ensuring stable operation of key components under high-load, long-duration working conditions.

V. Reasons to Choose CISOLUBE Auto Lubrication Systems

Industry Trust: CISOLUBE GT / GP203 pumps are widely used in agricultural machinery and industrial lubrication fields.

High Reliability: Supports continuous operation, resistant to high temperatures and corrosion.

Flexible Material Selection: Options include carbon steel and corrosion-resistant stainless steel to meet different operational needs.

Simplified Maintenance: Centralized grease supply reduces manual operation frequency and lowers downtime costs.

VI. Conclusion

Auto lubrication systems are the core solution for ensuring the long-term stable operation of booms and key components on agricultural sprayers. The GT / GP203 Auto Lubrication Pumps + DSP / DSPP Distributors combination provided by CISOLUBE can cover all lubrication points on the sprayer, achieving metered, timed, and automated lubrication. This makes it an ideal choice for medium and large sprayers, including self-propelled models.
