NorthStar PTO Generator — 13,000 Surge Watts
The NorthStar PTO generator targets farms needing robust peak output with steady rated power. It uses a 1-3/8 inch, 6-spline input shaft geared for 540 RPM, and 100% copper windings for durability and efficient performance. A metal housing supports long life in field conditions, while a 100 Amp thermal magnetic breaker and a plastic shield contribute to safe operation. Outlets include a welding receptacle and four 120V 20 Amp receptacles plus a voltmeter, enabling versatile on-site power for workshops and temporary irrigation pumps.
IMDLLC 10011P PTO Generator Package — 10 kW
The IMDLLC 10011P provides simultaneous 120V and 240V output with a heavy-duty, brush-type single-phase design. It relies on 100% copper windings and a pre-sealed, maintenance-free bearing system housed in a durable aluminum and steel shell. The magnetic circuit breaker offers separate overload protection, and a drip-proof design helps protect internal components. A three-bar LED meter displays Hertz, Volts, and Amps for real-time monitoring, while the standard 1-3/8″, 6-spline input shaft delivers safe 540 RPM PTO speed. Assembly support is available in the USA.
IMDLLC 16002P PTO Generator — 16 kW
The IMDLLC 16002P is designed for higher-demand applications with a continuous 16 kW output. It features simultaneous 120V and 240V operation, full power outlets, and a robust aluminum-steel housing for durability in harsh field environments. A heavy-duty automatic voltage regulator maintains consistent output, while the 1-3/8″ x 6-spline input shaft ensures reliable PTO coupling at 540 RPM. The unit is assembled in the USA with access to local sales and technical support, aiding maintenance and troubleshooting.

Buying Guide: Key Considerations For Tractor PTO Generators
Power output vs. load: Match continuous wattage to the expected average workload. For irrigation pumps or heavy-duty equipment, prioritize higher continuous kilowatts (kW) and surge watts to handle startup draws.
RPM and shaft compatibility: Ensure a 540 RPM PTO with a compatible input shaft (1-3/8″ and 6-spline) for secure, noise-minimized operation. Check shaft length and alignment requirements, including adjustable or telescoping options when needed.
Build quality and longevity: Metal housings, copper windings, and sealed bearings contribute to durability in outdoor farm environments. Look for drip-proof designs and protective shields for safer long-term use.
Safety and protection: Magnetic circuit breakers, voltmeter displays, and individual overload protection help prevent damage to equipment and reduce risk. Outlets and welding receptacles should be rated for the expected loads and applications.
Support and compatibility: Units with U.S.-based assembly and local technical support can simplify maintenance. Replacements and OEM-compatible options improve long-term viability if parts are needed later.
Maintenance needs: Consider units with low-maintenance designs, such as sealed bearings and simple electrical circuits. Copper windings generally offer better efficiency and longevity than aluminum windings in many PTO generators.
Application fit: For farms with multiple tasks, a 10–16 kW range often balances common needs like irrigation pumps, cold-weather machinery, and mobile shop power. For welding or heavy startup tasks, a higher surge capacity is advantageous.
Portability and installation: Review mounting and stand requirements, dimensions, and weight. Some units are designed for quick coupling to standard tractors, while others may require additional adapters or shields for safe operation.
Cost of ownership: Beyond the purchase price, factor in maintenance, spare parts availability, and potential downtime. Replacing a failed unit with a compatible OEM option can reduce total ownership costs in the long run.
