PTO Electric Alternator 15KW Continuous /16KW Peak
The 15KW PTO Electric Alternator is designed for small tractors with at least a 30 HP engine to produce clean, efficient power. It provides a robust output shaft of 1-3/8″ with a 6-spline drive and multiple outlets: two 20 amp 120V outlets, one 30 amp 120V twist-lock, one 120/240V four-prong, and a 12V DC outlet. It also includes circuit breakers for safety and UL-listed receptacles. Best for: farm tasks where multiple outlets are needed and the unit will run from a tractor PTO at 540 RPM. Limitation: heavy setup may require proper mounting and alignment to the 6-tooth spline shaft.
IMDLLC 22005P PTO Generator Package, 22 kW
This 22 kW PTO generator package combines heavy-duty, single-phase operation with 120V and 240V simultaneous output. Features include 100% copper windings, pre-sealed bearings, a durable aluminum/steel housing, magnetic circuit breaker protection, a drip-proof design, and a Three Bar LED meter displaying Hertz, Volts, and Amps. Best for: users needing reliable, higher-power PTO output with added safety protections. Limitation: internal wiring and maintenance access may require professional handling for service.
IMDLLC 16002P PTO Generator with Auto Voltage Regulator, 16 kW
This 16 kW generator features an automatic voltage regulator to maintain stable output for sensitive equipment. It provides 120V and 240V at the same time, 100% copper windings, pre-sealed bearings, and a durable aluminum/steel housing. With a 1-3/8″ 6-spline input at 540 RPM, it suits tractors needing dependable voltage control. Best for: users needing consistent voltage for tools that require steady power. Limitation: automatic voltage regulation may still require monitoring under extreme loads or irregular PTO speeds.
PTO CONTROL TOWER COMBO KIT – W/O KICKOUT STYLE – 10″
The PTO Control Tower Combo Kit offers a compact solution for coordinating PTO power delivery. While not a generator itself, it provides a streamlined control interface for PTO-driven setups. Best for: users who want centralized control components in a 3-point hitch system. Limitation: it does not include an engine or generator and must be paired with compatible PTO generators or power units.
Upgraded PTO Extension PTO Extender Adapter (GOWENIC)
The universal PTO extender enhances shaft compatibility by extending or bridging PTO connections. It features a 1 3/8″ 6-spline design compatible with tractors up to 70 HP. Best for: users needing to adapt PTO shafts to match distance between tractor and implement. Limitation: extension devices can introduce additional alignment considerations and potential vibration if not properly mounted.
Buying Guide
What to consider when choosing a 3 point PTO generator:
- Tractor compatibility: Confirm the shaft size (1-3/8″ and 6-spline) and PTO speed (540 RPM) for proper fit and performance.
- Power needs: Match kilowatt output to the tools you plan to run. Higher wattage offers more flexibility but requires a robust tractor or a dedicated power source.
- Voltage requirements: If you operate both 120V and 240V tools, ensure the unit supports simultaneous dual-voltage output and proper circuit protection.
- Outlets and safety: Look for multiple outlets, circuit breakers, and UL-listed receptacles for safer operation.
- Durability and mounting: Consider a unit with a sturdy housing and a secure 3-point hitch mount for stable operation in fields or yards.
- Maintenance: Seek models with sealed bearings and copper windings for longevity and lower maintenance.
- Support and parts availability: Prefer brands with local technical support and readily available service parts.
FAQ
- What is a PTO generator used for? – It converts tractor PTO power into electrical power for tools and equipment away from main electrical sources.
- What output size do I need for typical farm tools? – Most common tools run on 120V or 240V outlets; confirm wattage per tool and total load.
- Do all PTO generators require automatic voltage regulation? – Not always, but AVR helps maintain stable voltage for sensitive equipment.
- Can I mix PTO extenders with generators? – Yes, but ensure alignment and safe clearance to avoid binding or vibration.
- Is 540 RPM the standard PTO speed? – Yes, many 3-point hitch systems operate at 540 RPM, but verify your tractor’s specification.
- Do I need professional installation? – Complex setups or high-power units may benefit from professional mounting and wiring.
