What is a Pilotless® PTO?
A Pilotless® Power Take-Off (PTO) is a mechanical PTO that eliminates the traditional pilot bearing found in conventional PTO designs. WPT Power pioneered and trademarked the Pilotless® Mechanical PTO to address long-standing maintenance and performance challenges while improving reliability for demanding applications such as irrigation.
Why did WPT develop the Pilotless® PTO?
For decades, mechanical PTO design remained largely unchanged. WPT challenged that traditional approach by engineering the Pilotless® PTO to eliminate the pilot bearing and address several inherent limitations. By removing direct loading from the engine crankshaft, the Pilotless® design helps extend engine main bearing life while eliminating the need for critical pilot bearing alignment during installation. The result is a more robust drivetrain solution that reduces maintenance requirements, improves installation efficiency, and delivers reliable performance in demanding continuous-duty applications.
What are the benefits of a Pilotless® PTO?
A Pilotless® PTO offers several advantages over traditional mechanical PTO designs, including:
- Up to a 70 percent increase in sideload capacity
- Time-saving assembly with no pilot bearing alignment required
- Simplified maintenance along with reduced inventory
- Reduced downtime during irrigation seasons
These benefits help irrigation systems operate longer with fewer interruptions, allowing growers to maximize productivity during critical watering periods.

Why is PTO reliability important for Australian cotton irrigation?
Cotton irrigation pump systems frequently operate under continuous-duty conditions for extended periods during the growing season, placing sustained loads on the engine drivetrain and PTO assembly. Under these demanding operating cycles, component reliability becomes critical to maintaining uninterrupted water delivery. A robust Pilotless® PTO design helps withstand these continuous loads while reducing maintenance requirements and the risk of unplanned failures, allowing irrigation systems to operate efficiently when consistent water application is essential for crop performance.
Which WPT PTOs are designed for irrigation applications?
Working with an Australian distributor, DieselGas Moree, which specializes in the irrigation market, WPT developed solutions specifically for Australia’s irrigation industry. Two products designed for continuous irrigation service include:
- Pilotless® Constant Duty Series (CDS) PTO
- Hydraulically actuated Pilotless® Over-the-Shaft (OTS) PTO
Both are engineered to provide dependable performance in continuous-duty irrigation applications.
How does eliminating the pilot bearing improve PTO performance?
By eliminating the pilot bearing, the Pilotless® PTO removes a common wear point found in conventional PTO designs while simplifying installation and reducing ongoing maintenance requirements. The optimized drivetrain design enhances overall durability and provides dependable power transmission under sustained operating conditions, making it well suited for demanding irrigation applications.
How long has WPT’s Pilotless® PTO been in service?
WPT introduced the Pilotless® Mechanical PTO nearly a decade ago, representing an important development in mechanical PTO design. Since its introduction, the technology has undergone continuous engineering evaluation and has demonstrated proven performance among demanding industrial and agricultural applications. Years of real-world operating experience like this have further validated the Pilotless® design, providing customers with a dependable solution backed by extensive field experience.
What makes WPT’s Pilotless® PTO different from newer alternatives?
As the advantages of pilot-bearing-free PTO designs have become increasingly recognized, other manufacturers have introduced similar concepts. WPT, however, pioneered the Pilotless® Mechanical PTO and brings nearly a decade of proven field performance to the technology. Customers benefit from an established design refined over years of engineering development, application expertise, and successful operation in tough environments, rather than an emerging design still forming its performance history.
What other WPT PTO solutions are available for irrigation applications?
Reliable irrigation depends on selecting the right PTO for the application. Different pump installations, drive systems, and engine configurations require PTO solutions engineered to meet their specific operating demands. WPT offers a broad portfolio of mechanical and hydraulic PTOs designed to deliver dependable power transmission across a wide range of agricultural irrigation applications.
Part of the Pilotless® product family, WPT offers Type 1 mechanical and hydraulic PTOs. Specifically engineered for belt-driven agricultural irrigation pump systems, Type 1 PTOs are built to handle exceptionally high belt tension and side loads. Their rugged design provides long-lasting, dependable performance in demanding irrigation environments, helping keep pumps operating efficiently throughout the growing season.
How does the Pilotless® PTO help reduce irrigation downtime?
Unforeseen downtime during irrigation can interrupt water delivery and impact crop productivity. The Pilotless® PTO is designed to improve drivetrain reliability by eliminating the pilot bearing, reducing maintenance requirements, and simplifying installation. Combined with its resilient mechanical design, these features help maximize equipment availability and support dependable operation throughout demanding irrigation schedules.
