Electric vs PTO Systems: Pros and Cons for Dairy Farm Effluent Management

Reliability and Regulatory Compliance

Electric System: More automated but specifying the correct equipment and design layout is critical for long-term compliance and reliability.

PTO System: Often fewer moving parts or less pieces of equipment so they can be reliable if the human labour is available to operate it. Can be more accurate in its proof of placement of the effluent for assurance with regulatory compliance.

Upfront Costs

Electric System: Sometimes higher initial investment due to electric infrastructure requirements.

PTO System: Sometimes lower initial costs as it utilizes existing tractor to power the equipment.

​Pros

• Automation for efficient stirring and pumping of effluent.
• Lower labour costs and increased operational efficiency.
• Suitable for farms with access to a reliable power source.

Cons

• Often higher upfront investment. Need to spec the system for future expansion.
• Not ideal for multiple locations or can be farm expansion.
• Susceptible to power outages and electrical failures.

​Pros

• Versatility and mobility, suitable for off-the-grid locations.
• Can be used in multiple locations or sold if farm operations change.
• Lower initial costs due to utilizing existing tractor assets.

Cons

• Requires trained farm workers for operation and supervision.
• Relies on tractor engine, clocking up additional hours.
