Achieve consistently clean parts while reducing labor requirements

Arnold Machine heavy-duty parts washers safely and efficiently clean agricultural equipment parts. The innovative and durable design delivers consistent cleanliness levels for components of all shapes and sizes. 

Say goodbye to spending hours using dangerous chemicals to manually scrub caked-on grease, oil, and dirt. Our parts washers automate the cleaning process so your technicians can focus on more critical tasks.

Bring automated parts cleaning technology to your agricultural maintenance operations—Trust Arnold Machine to simplify washing, improve cleanliness, and boost productivity.


Improved Productivity

Workers can load parts into the machine and then focus on other essential responsibilities to maximize productivity.

Consistent Results

Enjoy consistent cleanliness levels—unlike manual methods where results can vary based on the component or employee.

Engineered to Last

Arnold Machine parts washers can last upwards of 30+ years with the proper replacement parts and minimal upkeep.


We offer cutting-edge enhancements to boost the power and productivity of your industrial parts washing system. Our specialized capabilities allow for complete customization to meet your exact cleaning requirements.

We can integrate the following technologies into any of our washers:


Ultrasonics in a parts washer work through a process called cavitation. High-frequency sound waves, produced by transducers in the cleaning solution, create alternating high-pressure and low-pressure cycles. 

During the low-pressure cycle, tiny vacuum bubbles form and grow. Once these bubbles reach a critical size, they collapse during the high-pressure cycle, releasing energy as shockwaves and micro-jets. This energy dislodges contaminants and residues from parts. 

The cleaning solution helps dissolve and remove the dislodged contaminants. Overall, ultrasonics provide a robust and efficient cleaning method, penetrating hard-to-reach areas while minimizing manual scrubbing.

Check out our case study to see how we helped a company increase the parts per hour throughput while providing a safer and more efficient cleaning process.

Vacuum Drying

Drying parts after wash and rinse cycles often prove complex in automated systems. Conventional drying via high-velocity air or heat cannot fully dry parts, especially those with blind holes, tapped holes, and worm trails. Vacuum drying thoroughly evaporates liquid from the deepest recesses where air drying fails. It guarantees 100% dryness when paired with a traditional blow-off.

Chemical Monitoring

Chemical monitoring automatically ensures proper soap distribution for hands-off process optimization. It maintains peak chemical concentrations without human intervention.

Automatic Chemical Addition

Automated chemical addition eliminates waste and human miscalculations by adding the required soap amounts. The washer handles chemical replenishment automatically.

Automated or Robotic Load and Unload

We can automatically or robotically load and unload parts into and out of the washer. Automation eliminates manual labor from the process. Read our case study to learn how we helped a manufacturer achieve a specific cleanliness level for their parts.


Clean parts are essential to avoid costly farm equipment breakdowns. For example, keeping a tractor's fuel lines free of debris is critical to prevent breakdowns, expensive repairs, and downtime.

Arnold Machine designs and builds custom agricultural parts washers to tackle any cleaning challenge, including intricate parts and hard-to-access areas. Our advanced machines deliver precision cleaning—from removing oils and grime to cleaning fuel system internals.

We engineer each parts washer based on your needs, including:

  • Part geometries
  • Part dimensions (large or small)
  • Target cleanliness levels
  • Daily volume requirements
  • Specific contaminants to eliminate

Our state-of-the-art, heavy-duty washers ensure peak performance, reduce labor requirements, and keep your operation running smoothly.
